## [Unreleased]

### Added

- Add `TokenListService`, a shared service for fetching and caching the token list per chain ([#8700](https://github.com/MetaMask/core/pull/8700))
  - Wraps `@tanstack/query-core` to cache results in-memory for 4 hours per chain ID, matching `TokenListController`'s existing threshold.
  - Multiple controllers sharing the same `TokenListService` instance share the same cache: only one HTTP request is made per chain per 4-hour window regardless of how many callers invoke `fetchTokensByChainId`.
  - Exported from the package as `TokenListService` and `buildTokenListMap`.
- Add `@tanstack/query-core` as a direct dependency ([#8700](https://github.com/MetaMask/core/pull/8700))
- Expose missing public `AccountTrackerController` methods through its messenger ([#8693](https://github.com/MetaMask/core/pull/8693))
  - The following actions are now available:
    - `AccountTrackerController:refresh`
    - `AccountTrackerController:syncBalanceWithAddresses`
  - Corresponding action types are available as well.
- Expose missing public `TokenBalancesController` methods through its messenger ([#8693](https://github.com/MetaMask/core/pull/8693))
  - The following actions are now available:
    - `TokenBalancesController:updateBalances`
    - `TokenBalancesController:resetState`
  - Corresponding action types are available as well.

### Changed

- **BREAKING:** `TokenDetectionController` now requires a `tokenListService: TokenListService` constructor option ([#8700](https://github.com/MetaMask/core/pull/8700))
  - Token list data is fetched directly from `TokenListService` instead of reading `TokenListController` state on each detection pass.
  - `GetTokenListState` has been removed from `AllowedActions` and `TokenListStateChange` has been removed from `AllowedEvents` on `TokenDetectionControllerMessenger`.
- **BREAKING:** `TokensController` now requires a `tokenListService: TokenListService` constructor option ([#8700](https://github.com/MetaMask/core/pull/8700))
  - `TokenListStateChange` has been removed from `AllowedEvents` on `TokensControllerMessenger`.
  - Token `name` and `rwaData` enrichment now happens once at controller initialization instead of reactively on every `TokenListController:stateChange` event.
- Bump `@metamask/transaction-controller` from `^65.0.0` to `^65.1.0` ([#8691](https://github.com/MetaMask/core/pull/8691))
- Switch the default mUSD asset from upfront `allTokens` state seeding to detection-based discovery on Ethereum mainnet (`0x1`), Linea (`0xe708`), and Monad mainnet (`0x8f`) ([#8688](https://github.com/MetaMask/core/pull/8688))
  - `TokenDetectionController` now merges mUSD into the in-memory token list cache for these chains so it is treated as a regular detection candidate, replacing the previous `start()`-time `TokensController:addTokens` call and the per-event re-seed runs.
  - `TokenBalancesController` schedules mUSD for import on the same chains even when the Accounts API returns a zero balance, so users without a current mUSD balance still see the token.
  - Drops Monad testnet (`0x279f`) from the default mUSD chain list.
- Bump `@metamask/network-enablement-controller` from `^5.0.2` to `^5.1.0` ([#8665](https://github.com/MetaMask/core/pull/8665))
- Bump `@metamask/keyring-controller` from `^25.3.0` to `^25.4.0` ([#8665](https://github.com/MetaMask/core/pull/8665))
- Bump `@metamask/accounts-controller` from `^37.2.0` to `^38.0.0` ([#8665](https://github.com/MetaMask/core/pull/8665))
- Bump `@metamask/account-tree-controller` from `^7.1.0` to `^7.2.0` ([#8665](https://github.com/MetaMask/core/pull/8665))

### Removed

- `TokenDetectionController` no longer restarts token detection when `TokenListController` publishes a `stateChange` event ([#8700](https://github.com/MetaMask/core/pull/8700))
  - Detection is still triggered on wallet unlock, account change, network change, and preference changes; the extra restart that occurred whenever `TokenListController` refreshed its cache is gone.
- Stop seeding mUSD directly into `TokensController` state and remove the related event subscriptions ([#8688](https://github.com/MetaMask/core/pull/8688))
  - `TokensController` no longer subscribes to `KeyringController:unlock`, `AccountsController:accountAdded`, `AccountsController:selectedEvmAccountChange`, `NetworkController:networkAdded`, or `NetworkController:stateChange` for mUSD seeding purposes.
  - `TokensControllerMessenger` no longer requires `NetworkControllerNetworkAddedEvent`, `AccountsControllerAccountAddedEvent`, or `KeyringControllerUnlockEvent` as allowed events.
  - Detection-based discovery (see Changed) covers the same user-facing behavior on supported chains.

## [105.1.0]

### Added

- Seed mUSD (`0xaca92e438df0b2401ff60da7e4337b687a2435da`) into `allTokens` state as a default tracked asset on Ethereum mainnet (`0x1`), Linea (`0xe708`), Monad mainnet (`0x8f`), and Monad testnet (`0x279f`) ([#8620](https://github.com/MetaMask/core/pull/8620))
  - `TokenDetectionController.start()` now calls `TokensController:addTokens` for mUSD on every supported chain that is configured in `NetworkController` — this is the primary trigger and uses the proven `addTokens` API. Re-runs on `AccountsController:selectedEvmAccountChange` (since `addTokens` only seeds for the currently selected account).
  - `TokensController` also seeds mUSD directly into state as a defense-in-depth measure: at startup for existing EVM accounts, on accounts already in persisted `allTokens` state, on `AccountsController:accountAdded`, on `AccountsController:selectedEvmAccountChange`, on `KeyringController:unlock`, on `NetworkController:networkAdded`, and on `NetworkController:stateChange` add patches.
  - `TokensControllerMessenger` now requires `NetworkControllerNetworkAddedEvent`, `AccountsControllerAccountAddedEvent`, and `KeyringControllerUnlockEvent` as allowed events.
- Add ZetaChain network support (`7000`/`0x1b58`) ([#8627](https://github.com/MetaMask/core/pull/8627))

### Changed

- Bump `@metamask/permission-controller` from `^12.3.0` to `^13.0.0` ([#8661](https://github.com/MetaMask/core/pull/8661))
- Bump `@metamask/keyring-api` from `^23.0.1` to `^23.1.0` ([#8647](https://github.com/MetaMask/core/pull/8647))
- Bump `@metamask/keyring-internal-api` from `^10.1.1` to `^11.0.1` ([#8584](https://github.com/MetaMask/core/pull/8584), [#8647](https://github.com/MetaMask/core/pull/8647))
- Bump `@metamask/messenger` from `^1.1.1` to `^1.2.0` ([#8632](https://github.com/MetaMask/core/pull/8632))
- Bump `@metamask/keyring-controller` from `^25.2.0` to `^25.3.0` ([#8634](https://github.com/MetaMask/core/pull/8634))
- Bump `@metamask/network-controller` from `^30.0.1` to `^30.1.0` ([#8636](https://github.com/MetaMask/core/pull/8636))

### Fixed

- Correct the seeded mUSD token decimals from `18` to `6` in `TokensController` and `TokenDetectionController` defaults so tracked token metadata matches contract precision ([#8664](https://github.com/MetaMask/core/pull/8664))

## [105.0.0]

### Added

- Expose missing public `CurrencyRateController` methods through its messenger ([#8561](https://github.com/MetaMask/core/pull/8561))
  - The following actions are now available:
    - `CurrencyRateController:setCurrentCurrency`
    - `CurrencyRateController:updateExchangeRate`
  - Corresponding action types (e.g. `CurrencyRateControllerSetCurrentCurrencyAction`) are available as well.

### Changed

- **BREAKING:** Standardize names of `CurrencyRateController` messenger action types ([#8561](https://github.com/MetaMask/core/pull/8561))
  - The `GetCurrencyRateState` messenger action has been renamed to `CurrencyRateControllerGetStateAction` to follow the convention. You will need to update imports appropriately.
  - These changes only affect the types. The action type strings themselves have not changed, so you do not need to update the list of actions you pass when initializing `CurrencyRateController` messenger.
- `MultichainAssetsController`: Restore fail-open behavior for Blockaid spam token filter ([#8580](https://github.com/MetaMask/core/pull/8580))
  - Uses blacklist approach: only rejects tokens explicitly marked as malicious by Blockaid
  - When Blockaid bulk token scan API calls fail or return no results, tokens are allowed through
  - This prevents legitimate tokens from being blocked due to API outages, network issues, or missing token data
  - Malicious tokens that slip through are caught by the periodic rescan (runs daily by default)
- Bump `@metamask/transaction-controller` from `^64.3.0` to `^65.0.0` ([#8585](https://github.com/MetaMask/core/pull/8585), [#8613](https://github.com/MetaMask/core/pull/8613))

### Fixed

- Fix `selectAssetsBySelectedAccountGroup` crashing when an account referenced in the account tree is missing from internal accounts ([#8604](https://github.com/MetaMask/core/pull/8604))

## [104.3.0]

### Added

- Export `SPOT_PRICES_SUPPORT_INFO` from the token prices service ([#8483](https://github.com/MetaMask/core/pull/8483))

## [104.2.0]

### Added

- Add Tempo Mainnet (`4217`/`0x1079`) multicall contract support ([#8346](https://github.com/MetaMask/core/pull/8346))
- Add Forma (`0xf043a` / `eip155:984122`) to `SPOT_PRICES_SUPPORT_INFO`, mapping its native TIA asset to `slip44:984122` so the price-api can resolve it to CoinGecko's `celestia` coin ([#8524](https://github.com/MetaMask/core/pull/8524))

## [104.1.0]

### Added

- `MultichainAssetsController`: periodic Blockaid re-scan of stored SPL-style `token:` assets (default once per day) so tokens that become malicious after a prior scan are dropped; use constructor option `blockaidTokenRescanInterval` (ms), or `0` to disable. ([#8400](https://github.com/MetaMask/core/pull/8400))
- Added Injective Mainnet native token to Price API supported chains ([#8487](https://github.com/MetaMask/core/pull/8487))

### Changed

- Bump `@metamask/account-tree-controller` from `^7.0.0` to `^7.1.0` ([#8472](https://github.com/MetaMask/core/pull/8472))
- Bump `@metamask/transaction-controller` from `^64.2.0` to `^64.3.0` ([#8482](https://github.com/MetaMask/core/pull/8482))
- Bump `@metamask/keyring-api` from `^21.6.0` to `^23.0.1` ([#8464](https://github.com/MetaMask/core/pull/8464))

### Fixed

- Used the `removed` property coming from `MultichainAssetsController:accountAssetListUpdated` event body to manage stale balances ([#8461](https://github.com/MetaMask/core/pull/8461))
- `MultichainAssetsController`: fungible `token:` assets from automatic detection are no longer added when Blockaid bulk scan fails, returns empty, or omits that address (previously fail open); an explicit non-malicious per-token result from `PhishingController:bulkScanTokens` is now required before add. ([#8400](https://github.com/MetaMask/core/pull/8400))
- Fix `AccountTrackerController` wiping existing balances on other chains when syncing accounts for a chain that has no state entry yet ([#8505](https://github.com/MetaMask/core/pull/8505))

## [104.0.0]

### Changed

- **BREAKING:** `NftController` no longer uses the `AssetsContractController:getERC721OwnerOf` and `AssetsContractController:getERC1155BalanceOf` messenger actions for ownership checks; these have been removed from `AllowedActions` ([#8281](https://github.com/MetaMask/core/pull/8281))
  - Consumers that construct the `NftController` messenger and register handlers for these two actions must remove them from their allowed actions list.
- **BREAKING:** `checkAndUpdateSingleNftOwnershipStatus` no longer accepts a `batch` boolean as its second argument; the signature is now `(nft, networkClientId, { userAddress }?)` ([#8281](https://github.com/MetaMask/core/pull/8281), [#8435](https://github.com/MetaMask/core/pull/8435))
  - The method now always writes the updated NFT to state and returns it. Remove the `batch` argument from all call sites.
- **BREAKING:** `checkAndUpdateAllNftsOwnershipStatus` now removes NFTs confirmed as unowned from state instead of setting `isCurrentlyOwned: false` on them ([#8281](https://github.com/MetaMask/core/pull/8281))
  - The `isCurrentlyOwned: false` flag was originally used to power a "Previously Owned" NFTs section in MetaMask, which is no longer supported. NFTs that are confirmed as no longer owned are now removed from state immediately rather than being retained with a stale flag.
- `NftController` NFT ownership checks (`isNftOwner`, `checkAndUpdateSingleNftOwnershipStatus`, `checkAndUpdateAllNftsOwnershipStatus`) now use Multicall3 to batch ERC-721 `ownerOf` and ERC-1155 `balanceOf` calls into fewer RPC requests, falling back to individual calls on unsupported chains ([#8281](https://github.com/MetaMask/core/pull/8281))
- Bump `@metamask/accounts-controller` from `^37.1.1` to `^37.2.0` ([#8363](https://github.com/MetaMask/core/pull/8363))
- Bump `@metamask/keyring-controller` from `^25.1.1` to `^25.2.0` ([#8363](https://github.com/MetaMask/core/pull/8363))
- Bump `@metamask/messenger` from `^1.0.0` to `^1.1.1` ([#8364](https://github.com/MetaMask/core/pull/8364), [#8373](https://github.com/MetaMask/core/pull/8373))
- Bump `@metamask/transaction-controller` from `^64.0.0` to `^64.2.0` ([#8432](https://github.com/MetaMask/core/pull/8432), [#8447](https://github.com/MetaMask/core/pull/8447))
- Bump `@metamask/base-controller` from `^9.0.1` to `^9.1.0` ([#8457](https://github.com/MetaMask/core/pull/8457))

### Fixed

- Restore `checkAndUpdateSingleNftOwnershipStatus` to `NftController` to fix a regression where consumers (e.g. the MetaMask extension) that call this method individually were broken by its removal in [#8281](https://github.com/MetaMask/core/pull/8281) ([#8435](https://github.com/MetaMask/core/pull/8435))

## [103.1.1]

### Changed

- Bump `@metamask/network-enablement-controller` from `^5.0.1` to `^5.0.2` ([#8359](https://github.com/MetaMask/core/pull/8359))

- Bump `@metamask/transaction-controller` from `^63.3.1` to `^64.0.0` ([#8359](https://github.com/MetaMask/core/pull/8359))

## [103.1.0]

### Changed

- Bump `@metamask/controller-utils` from `^11.19.0` to `^11.20.0` ([#8344](https://github.com/MetaMask/core/pull/8344))
- Hide native tokens on Tempo networks (testnet and mainnet) in asset selectors ([#7882](https://github.com/MetaMask/core/pull/7882))
- Force `occurrenceFloor` to `1` for Tempo Mainnet in `token-service.ts` ([#7882](https://github.com/MetaMask/core/pull/7882))

### Fixed

- Fix `NftControllerMessenger` actions union type resolving to `any` for consumers ([#8350](https://github.com/MetaMask/core/pull/8350))
- Fix `NftDetectionControllerMessenger` actions union type resolving to `any` for consumers ([#8350](https://github.com/MetaMask/core/pull/8350))

## [103.0.0]

### Changed

- **BREAKING:** Bump `@metamask/snaps-controllers` from `^17.2.0` to `^19.0.0` ([#8319](https://github.com/MetaMask/core/pull/8319))
  - The controllers now require `SnapController:getRunnableSnaps` instead of `SnapController:getAll`.
- Bump `@metamask/snaps-sdk` from `^10.3.0` to `^11.0.0` ([#8319](https://github.com/MetaMask/core/pull/8319))

- Bump `@metamask/account-tree-controller` from `^6.0.0` to `^7.0.0` ([#8325](https://github.com/MetaMask/core/pull/8325))
- Bump `@metamask/accounts-controller` from `^37.1.0` to `^37.1.1` ([#8325](https://github.com/MetaMask/core/pull/8325))
- Bump `@metamask/multichain-account-service` from `^8.0.0` to `^8.0.1` ([#8325](https://github.com/MetaMask/core/pull/8325))
- Bump `@metamask/profile-sync-controller` from `^28.0.1` to `^28.0.2` ([#8325](https://github.com/MetaMask/core/pull/8325))

### Fixed

- `TokenBalancesController` batches rapid `updateBalances` calls: multiple requests within a short timeframe are coalesced and processed once, reducing redundant balance fetches ([#8246](https://github.com/MetaMask/core/pull/8246))

## [102.0.0]

### Added

- Add Tempo Mainnet (`4217`/`0x1079`) and Tempo Moderato Testnet (`42431`/`0xa5bf`) support ([#8258](https://github.com/MetaMask/core/pull/8258))
  - Add `0x1079` and `0xa5bf` to `SPOT_PRICES_SUPPORT_INFO` in `codefi-v2.ts`

  - Add `0xa5bf` (only Tempo Testnet) to `MULTICALL_CONTRACT_BY_CHAINID` in `multicall.ts`

### Changed

- **BREAKING:** `AssetListState` type now requires a top-level `selectedAccountGroup` property, matching the updated `AccountTreeControllerState` shape where `selectedAccountGroup` was moved out of `accountTree` ([#8245](https://github.com/MetaMask/core/pull/8245))

### Changed

- Bump `@metamask/core-backend` from `^6.1.1` to `^6.2.0` ([#8232](https://github.com/MetaMask/core/pull/8232))

### Fixed

- `TokenBalancesController` no longer crashes when `AccountActivityService:statusChanged` emits non-EVM chain IDs (e.g. `solana:mainnet`); such chains are now silently skipped ([#8228](https://github.com/MetaMask/core/pull/8228))

## [101.0.0]

### Added

- Add Stable network (chain 988) support ([#8185](https://github.com/MetaMask/core/pull/8185))

  - The following action is now available:
    - `MultichainAssetsRatesController:fetchHistoricalPricesForAsset`
  - Corresponding action type (`MultichainAssetsRatesControllerFetchHistoricalPricesForAssetAction`) is available as well.

  - The following actions are now available:
    - `TokenDetectionController:enable`
    - `TokenDetectionController:disable`
    - `TokenDetectionController:start`
    - `TokenDetectionController:stop`
  - Corresponding action type (`TokenDetectionControllerEnableAction`) is available as well.
- Expose missing public `TokensController` methods through its messenger ([#8164](https://github.com/MetaMask/core/pull/8164))

### Changed

- Bump `@metamask/approval-controller` from `^8.0.0` to `^9.0.0` ([#8225](https://github.com/MetaMask/core/pull/8225))
- Bump `@metamask/network-enablement-controller` from `^4.2.0` to `^5.0.0` ([#8225](https://github.com/MetaMask/core/pull/8225))

- Updated `ApprovalController` method calls (`accept` → `acceptRequest`) ([#8183](https://github.com/MetaMask/core/pull/8183))
- **BREAKING:** Standardize names of `AccountTrackerController` messenger action types ([#8164](https://github.com/MetaMask/core/pull/8164))
  - All existing types for messenger actions have been renamed so they include `Controller` (e.g. `AccountTrackerUpdateNativeBalancesAction` -> `AccountTrackerControllerUpdateNativeBalancesAction`). You will need to update imports appropriately.
  - This change only affects the types. The action type strings themselves have not changed, so you do not need to update the list of actions you pass when initializing `AccountTrackerController` messengers.
- Remove hardcoded `supportedNftDetectionNetworks` chain allowlist from `NftDetectionController`; the NFT API now returns an empty array for unsupported chains instead of an error, so chain gating is no longer needed in the client ([#8180](https://github.com/MetaMask/core/pull/8180))
- `NftDetectionController` now skips the NFT API call entirely when all provided chain IDs are non-EVM (decimal `0`), returning an empty result immediately ([#8180](https://github.com/MetaMask/core/pull/8180))
- Update `ReservoirResponse.continuation` type from `string` to `string | null` to match the NFT API response shape ([#8180](https://github.com/MetaMask/core/pull/8180))
- Bump `@metamask/transaction-controller` from `^62.21.0` to `^63.0.0` ([#8217](https://github.com/MetaMask/core/pull/8217), [#8225](https://github.com/MetaMask/core/pull/8225))

### Fixed

- Add missing Tron staking lifecycle asset symbols to `TRON_RESOURCE` filter ([#8174](https://github.com/MetaMask/core/pull/8174))

## [100.2.1]

### Changed

- Bump `@metamask/profile-sync-controller` from `^27.1.0` to `^28.0.0` ([#8162](https://github.com/MetaMask/core/pull/8162))
- Bump `@metamask/account-tree-controller` from `^5.0.0` to `^5.0.1` ([#8162](https://github.com/MetaMask/core/pull/8162))
- Bump `@metamask/core-backend` from `^6.1.0` to `^6.1.1` ([#8162](https://github.com/MetaMask/core/pull/8162))

## [100.2.0]

### Added

- Add optional `networkConfigurationsByChainId` parameter to `calculateBalanceForAllWallets`, `calculateBalanceChangeForAllWallets`, and `calculateBalanceChangeForAccountGroup`. When provided, native (and staked-native) token balances fall back to `CurrencyRateController` when `TokenRatesController` has no market data for the chain, so aggregated balance can be displayed when only a native-currency rate is available. Export type `NetworkConfigurationNativeCurrency` for consumers passing network configs into these functions ([#8141](https://github.com/MetaMask/core/pull/8141))

### Changed

- Optimize NFT Controller state writes from O(2n) to O(2) for NFT detection by batching contract and NFT additions ([#8079](https://github.com/MetaMask/core/pull/8079))
- Remove on-chain ERC-721 RPC fallback for contract name and symbol in `NftController`; contract metadata is now sourced exclusively from the NFT API, eliminating `getERC721AssetName`/`getERC721AssetSymbol` calls during NFT detection. NFT contracts that previously had `name` or `symbol` populated via on-chain calls will no longer have those fields if the NFT API does not supply them ([#8079](https://github.com/MetaMask/core/pull/8079))
- When `isHomepageSectionsV1Enabled` is true, `AccountTrackerController` now uses all popular EVM networks (via `NetworkEnablementController:listPopularEvmNetworks`) for balance refresh on account change and keyring unlock, instead of only the enabled networks from `NetworkEnablementController` state ([#8117](https://github.com/MetaMask/core/pull/8117))
- Bump `@metamask/account-tree-controller` from `4.1.1` to `5.0.0` ([#8140](https://github.com/MetaMask/core/pull/8140))
- Bump `@metamask/accounts-controller` from `36.0.1` to `37.0.0` ([#8140](https://github.com/MetaMask/core/pull/8140))

- Bump `@metamask/multichain-account-service` from `7.0.0` to `7.1.0` ([#8140](https://github.com/MetaMask/core/pull/8140))
- Bump `@metamask/preferences-controller` from `22.1.0` to `23.0.0` ([#8140](https://github.com/MetaMask/core/pull/8140))
- Bump `@metamask/transaction-controller` from `62.20.0` to `62.21.0` ([#8140](https://github.com/MetaMask/core/pull/8140))

### Fixed

- Gate `TokenListController` polling on controller initialization to avoid duplicate token list API requests during startup races ([#8113](https://github.com/MetaMask/core/pull/8113))
- Update token balance fallback behavior so missing ERC-20 balances from `AccountsApiBalanceFetcher` are returned as `unprocessedTokens` and fetched through RPC fallback, rather than being forcibly set to zero ([#8132](https://github.com/MetaMask/core/pull/8132))

## [100.1.0]

### Added

- Export `MAP_CAIP_CURRENCIES` from the package (and from `MultichainAssetsRatesController`) so consumers can resolve selected currency to the same CAIP currency string used by MultichainAssetsRatesController ([#8076](https://github.com/MetaMask/core/pull/8076))
- Add `includeTokenSecurityData` option to `searchTokens` and `getTrendingTokens` to request token security data from the API ([#8106](https://github.com/MetaMask/core/pull/8106))
- Add `fetchTokenAssets` function to fetch token metadata by CAIP-19 asset IDs from the `/assets` endpoint ([#8106](https://github.com/MetaMask/core/pull/8106))
  - Supports optional flags: `includeAggregators`, `includeCoingeckoId`, `includeLabels`, `includeMarketData`, `includeOccurrences`, `includeTokenSecurityData`, `includeRwaData`
- Export new types `TokenAsset`, `TokenSecurityData`, `TokenSecurityFeature`, `TokenSecurityHolder`, `TokenSecurityMarket`, `TokenSecurityFees`, `TokenSecurityFinancialStats`, and `TokenSecurityMetadata` ([#8106](https://github.com/MetaMask/core/pull/8106))

### Changed

- Bump `@metamask/network-enablement-controller` from `^4.1.2` to `^4.2.0` ([#8107](https://github.com/MetaMask/core/pull/8107))

### Fixed

- Fix `AccountsApiBalanceFetcher` to apply stricter conditions when zeroing out token balances ([#8044](https://github.com/MetaMask/core/pull/8044))
- Fix `AccountsApiBalanceFetcher` ERC-20 zeroing to only apply to accounts included in the current request, preventing stale-account entries from being incorrectly reset to zero ([#8095](https://github.com/MetaMask/core/pull/8095))

## [100.0.3]

### Changed

- Bump `@metamask/transaction-controller` from `^62.17.1` to `^62.18.0` ([#8005](https://github.com/MetaMask/core/pull/8005))

### Fixed

- Fix token search API parameter to use `first` instead of `limit` for pagination ([#8019](https://github.com/MetaMask/core/pull/8019))
  - Clamp limit to a maximum of 50 results for regular queries
  - Allow up to 500 results for Ondo token queries; limits exceeding 500 are clamped to 50

## [100.0.2]

### Changed

- Blockaid token filtering in `MultichainAssetsController` now only removes tokens flagged as `Malicious` ([#8003](https://github.com/MetaMask/core/pull/8003))
  - `Spam`, `Warning`, and `Benign` tokens are no longer filtered out

## [100.0.1]

### Changed

- Bump `@metamask/accounts-controller` from `^36.0.0` to `^36.0.1` ([#7996](https://github.com/MetaMask/core/pull/7996))
- Bump `@metamask/network-controller` from `^29.0.0` to `^30.0.0` ([#7996](https://github.com/MetaMask/core/pull/7996))
- Bump `@metamask/network-enablement-controller` from `^4.1.1` to `^4.1.2` ([#7996](https://github.com/MetaMask/core/pull/7996))

- Bump `@metamask/transaction-controller` from `^62.17.0` to `^62.17.1` ([#7996](https://github.com/MetaMask/core/pull/7996))

## [100.0.0]

### Added

- **BREAKING:** `MultichainAssetsControllerMessenger` now requires the `PhishingController:bulkScanTokens` action to be allowed ([#7923](https://github.com/MetaMask/core/pull/7923))
  - Consumers constructing the messenger must include this action in the allowed actions list
- Add Blockaid token security scanning to `MultichainAssetsController` to filter out spam, malicious, and warning tokens during automatic asset detection ([#7923](https://github.com/MetaMask/core/pull/7923))
  - Tokens with `assetNamespace` of "token" (e.g. SPL tokens) are scanned via the `PhishingController:bulkScanTokens` messenger action
  - Only tokens with a `Benign` result are kept; native assets (e.g. `slip44`) are not scanned
  - The filter fails open: if the scan is unreachable or returns an error, all tokens are kept
  - Filtering applies to account-added and asset-list-updated events; `addAssets` (curated list) is not filtered
  - Token addresses are batched into groups of 100 to stay within the `bulkScanTokens` per-request limit

- Added Chiliz Chain native token ([#7939](https://github.com/MetaMask/core/pull/7939))

### Changed

- Changed Plasma native token ([#7939](https://github.com/MetaMask/core/pull/7939))
- `searchTokens` now returns an optional `error` field when requests fail, allowing consumers to detect and handle search failures instead of silently receiving empty results ([#7938](https://github.com/MetaMask/core/pull/7938))

## [99.3.2]

### Changed

- Bump `@metamask/multichain-account-service` from `^5.1.0` to `^7.0.0` ([#7869](https://github.com/MetaMask/core/pull/7869), [#7897](https://github.com/MetaMask/core/pull/7897))
- Bump `@metamask/transaction-controller` from `^62.15.0` to `^62.17.0` ([#7872](https://github.com/MetaMask/core/pull/7872), [#7897](https://github.com/MetaMask/core/pull/7897))
- Bump `@metamask/phishing-controller` from `^16.1.0` to `^16.2.0` ([#7883](https://github.com/MetaMask/core/pull/7883))

- Bump `@metamask/transaction-controller` from `^62.13.0` to `^62.15.0` ([#7832](https://github.com/MetaMask/core/pull/7832), [#7854](https://github.com/MetaMask/core/pull/7854))

### Fixed

- Ensure TokenBalancesController zeroes out ERC tokens that are not returned from Accounts API ([#7861](https://github.com/MetaMask/core/pull/7861))
  - The Accounts API does not return tokens that are empty/have zero balance, but we need to make sure that the API service can return zero balance, so we can correctly update the TokenBalancesController state and prevent stale values (e.g. when a user swaps/sends all their balance for a given ERC-20 token - we need to update the state for that token to zero and not show the old value)

## [99.2.0]

  - No longer needed as cache clearing functionality has been removed

## [98.0.0]

### Changed

- **BREAKING:** `TokenListController` now persists `tokensChainsCache` via `StorageService` and requires clients to call `initialize()` after construction ([#7413](https://github.com/MetaMask/core/pull/7413))
  - Each chain's token cache is stored in a separate file, reducing write amplification
  - All chains are loaded in parallel at startup to maintain compatibility with TokenDetectionController
  - `tokensChainsCache` state metadata now has `persist: false` to prevent duplicate persistence
  - Clients must call `await controller.initialize()` before using the controller
  - State changes are automatically persisted via debounced subscription

  - Added `#isLocked` property to track keyring lock state, initialized from `KeyringController:getState`
  - Added `isActive` getter that returns `true` when keyring is unlocked and user is onboarded
  - Balance updates are now skipped when controller is not active (locked or not onboarded)
  - `KeyringController:unlock` event now only updates lock state without triggering immediate refresh
  - `KeyringController:lock` event sets controller to inactive state
- `AccountTrackerController` now only refreshes balances for the newly added network on `NetworkController:networkAdded` event instead of all networks ([#7492](https://github.com/MetaMask/core/pull/7492))
- Bump `@metamask/transaction-controller` from `^62.5.0` to `^62.7.0` ([#7494](https://github.com/MetaMask/core/pull/7494))

## [94.1.0]

### Added

- Add `excludeLabels` parameter to `getTrendingTokens` to filter out tokens by labels (e.g., 'stable_coin', 'blue_chip') ([#7466](https://github.com/MetaMask/core/pull/7466))
- Add support for spot prices on multiple new chains: Apechain, Lens, Plume, Flow EVM, Berachain, xrpl-evm, Fraxtal, Lukso, xdc-network, and Plasma ([#7465](https://github.com/MetaMask/core/pull/7465))
- Add `ape` to `SUPPORTED_CURRENCIES` for ApeCoin/Apechain native token ([#7465](https://github.com/MetaMask/core/pull/7465))
- Add `isOnboarded` constructor option to `TokenBalancesController` and `AccountTrackerController` ([#7469](https://github.com/MetaMask/core/pull/7469))
  - When `isOnboarded()` returns `false`, balance updates are skipped to prevent unnecessary API calls during onboarding
  - `TokenBalancesController.isActive` now also checks `isOnboarded()` in addition to `isUnlocked`
  - `AccountTrackerController.#refreshAccounts` now checks `isOnboarded()` before fetching balances

### Fixed

- Fix `TokenBalancesController` to evaluate `allowExternalServices` dynamically instead of only at constructor time ([#7469](https://github.com/MetaMask/core/pull/7469))
  - Previously, the `#balanceFetchers` array was built once in the constructor, so changes to `allowExternalServices()` after initialization were not reflected
  - Now `allowExternalServices()` is stored as a function and evaluated dynamically in the fetcher's `supports` method
- Fix `TokenDetectionController` methods `addDetectedTokensViaPolling` and `addDetectedTokensViaWs` to refresh token metadata cache before use ([#7469](https://github.com/MetaMask/core/pull/7469))
  - Previously, these methods used a potentially stale/empty `#tokensChainsCache` from construction time
  - Now they fetch the latest `tokensChainsCache` from `TokenListController:getState` before looking up token metadata
- Fix `AccountTrackerController.syncBalanceWithAddresses` to also check `isOnboarded()` before fetching balances ([#7469](https://github.com/MetaMask/core/pull/7469))
  - Previously, only `#refreshAccounts` checked `isOnboarded()`, but `syncBalanceWithAddresses` would still make RPC calls during onboarding
  - Now `syncBalanceWithAddresses` returns an empty object when `isOnboarded()` returns `false`

## [94.0.0]

### Added

- Add `firstPageOnly` and `signal` options to `NftDetectionController.detectNfts()` method to allow fetching only the first page of NFTs and aborting detection operations ([#7436](https://github.com/MetaMask/core/pull/7436))
- Support for Monad in NFT assets-controllers, [#7254](https://github.com/MetaMask/core/pull/7254)

### Changed

- Bump `@metamask/transaction-controller` from `^62.4.0` to `^62.5.0` ([#7325](https://github.com/MetaMask/core/pull/7325))
- **BREAKING:** Replace Account API v2 with Account API v4 for token auto-detection ([#7408](https://github.com/MetaMask/core/pull/7408))
  - `TokenDetectionController` now delegates token detection for Account API v4 supported chains to `TokenBalancesController`
  - RPC-based detection continues to be used for chains not supported by Account API v4
  - Added `forceRpc` parameter to `TokenDetectionController.detectTokens()` to force RPC-based detection
  - `TokenDetectionController:detectTokens` action is now registered for cross-controller communication
- `TokenBalancesController` now triggers RPC-based token detection as fallback when Account API v4 fails or returns unprocessed chains ([#7408](https://github.com/MetaMask/core/pull/7408))
  - Calls `TokenDetectionController:detectTokens` with `forceRpc: true` when fetcher fails
  - Calls `TokenDetectionController:detectTokens` with `forceRpc: true` for any unprocessed chain IDs returned by the API
- Refactored `TokenBalancesController` for improved code organization and maintainability ([#7408](https://github.com/MetaMask/core/pull/7408))
- Remove warning logs for failed chain balance fetches in RPC balance fetcher ([#7429](https://github.com/MetaMask/core/pull/7429))

- Bump `@metamask/transaction-controller` from `^62.4.0` to `^62.6.0` ([#7325](https://github.com/MetaMask/core/pull/7325), [#7430](https://github.com/MetaMask/core/pull/7430))
- Bump `@metamask/multichain-account-service` from `^4.0.0` to `^4.0.1` ([#7437](https://github.com/MetaMask/core/pull/7437)

### Fixed

- Fix stale `accountsAssets` reference in `MultichainAssetsRatesController` causing incorrect conversion rates for non-EVM chains when currency is changed ([#7424](https://github.com/MetaMask/core/pull/7424))
  - `MultichainAssetsRatesController` now dynamically fetches fresh state instead of caching a reference that becomes stale due to Immer's immutable updates
- **BREAKING:** `NftDetectionController` now calls a new function `NftController:addNfts` that reduces API calls to bulk-scan to batch multiple NFTs URLs ([#7411](https://github.com/MetaMask/core/pull/7411))
- Added decimal precision (default 9dp) for `CurrencyRateController` `conversionRate` and `conversionRate` properties. ([#7324](https://github.com/MetaMask/core/pull/7324))
  - This fixes any BigNumber conversion errors due to exceeding the 15 significant digit limit

- `AccountTrackerController` now normalizes addresses to lowercase internally before calling balance fetchers to match `TokenBalancesController` and enable HTTP request caching ([#7279](https://github.com/MetaMask/core/pull/7279))

### Fixed

- Fix 2dp value in `CurrencyRateController`([#7276](https://github.com/MetaMask/core/pull/7276))

- **BREAKING:** Add optional JWT token authentication to multi-chain accounts API calls ([#7165](https://github.com/MetaMask/core/pull/7165))
  - `fetchMultiChainBalances` and `fetchMultiChainBalancesV4` now accept an optional `jwtToken` parameter
  - `TokenDetectionController` fetches and passes JWT token from `AuthenticationController` when using Accounts API
  - `TokenBalancesController` fetches and passes JWT token through balance fetcher chain
  - JWT token is included in `Authorization: Bearer <token>` header when provided
  - Backward compatible: token parameter is optional and APIs work without authentication

### Changed

- Move peer dependencies for controller and service packages to direct dependencies ([#7209](https://github.com/MetaMask/core/pull/7209), [#7220](https://github.com/MetaMask/core/pull/7220), [#7236](https://github.com/MetaMask/core/pull/7236))
  - The dependencies moved are:
    - `@metamask/account-tree-controller` (^4.0.0)
    - `@metamask/accounts-controller` (^35.0.0)
    - `@metamask/approval-controller` (^8.0.0)
    - `@metamask/core-backend` (^5.0.0)
    - `@metamask/keyring-controller` (^25.0.0)
    - `@metamask/multichain-account-service` (^4.0.0)
    - `@metamask/network-controller` (^26.0.0)
    - `@metamask/permission-controller` (^12.1.1)
    - `@metamask/phishing-controller` (^16.1.0)
    - `@metamask/preferences-controller` (^22.0.0)
    - `@metamask/profile-sync-controller` (^27.0.0)
    - `@metamask/snaps-controllers` (^14.0.1)
    - `@metamask/transaction-controller` (^62.3.0)
  - In clients, it is now possible for multiple versions of these packages to exist in the dependency tree.
    - For example, this scenario would be valid: a client relies on `@metamask/controller-a` 1.0.0 and `@metamask/controller-b` 1.0.0, and `@metamask/controller-b` depends on `@metamask/controller-a` 1.1.0.
  - Note, however, that the versions specified in the client's `package.json` always "win", and you are expected to keep them up to date so as not to break controller and service intercommunication.

### Fixed

- Fix `TokenBalancesController` state that store both lowercase and checksum account addresses ([#7217](https://github.com/MetaMask/core/pull/7217))
- `TokenBalancesController`: state inconsistency by ensuring all account addresses are stored in lowercase format ([#7216](https://github.com/MetaMask/core/pull/7216))

  - Prevents token detection from hanging indefinitely on slow or unresponsive API requests
  - Automatically falls back to RPC-based token detection when API call times out or fails
  - Includes error logging for debugging timeout and failure events
- Handle `unprocessedNetworks` from Accounts API responses to ensure complete token detection coverage ([#7106](https://github.com/MetaMask/core/pull/7106))
  - When Accounts API returns networks it cannot process, those networks are automatically added to RPC detection
  - Applies to both `TokenDetectionController` and `TokenBalancesController`

### Fixed

- Check if `KeyringController` is unlocked before processing account events in `MultichainBalancesController` ([#5473](https://github.com/MetaMask/core/pull/5473))
  - This is needed since some Snaps might decrypt their state which needs the `KeyringController` to be unlocked.

- Removed polling mechanism in the `MultichainBalancesController` and now relies on the new `AccountsController:accountBalancesUpdated` event ([#5221](https://github.com/MetaMask/core/pull/5221))

### Fixed

- The tokens state is now updated only when the `tokenChainId` matches the currently selected chain ID. ([#5257](https://github.com/MetaMask/core/pull/5257))

## [47.0.0]

### Added

- Add `onBreak` and `onDegraded` methods to `CodefiTokenPricesServiceV2` ([#5109](https://github.com/MetaMask/core/pull/5109))
  - These serve the same purpose as the `onBreak` and `onDegraded` constructor options, but align more closely with the Cockatiel policy API.

### Changed

- Use new `@metamask/keyring-internal-api@^1.0.0` ([#4695](https://github.com/MetaMask/core/pull/4695))
  - This package has been split out from the Keyring API. Its types are compatible with the `@metamask/keyring-api` package used previously.

## [45.1.1]

### Changed

- Bump `@metamask/controller-utils` from `^11.3.0` to `^11.4.4` ([#5012](https://github.com/MetaMask/core/pull/5012))
- Bump `@metamask/polling-controller` from `^12.0.1` to `^12.0.2` ([#5012](https://github.com/MetaMask/core/pull/5012))

### Fixed

- Make implicit peer dependencies explicit ([#4974](https://github.com/MetaMask/core/pull/4974))
  - Add the following packages as peer dependencies of this package to satisfy peer dependency requirements from other dependencies:
    - `@metamask/providers` `^18.1.0` (required by `@metamask/keyring-api`)
    - `webextension-polyfill` `^0.10.0 || ^0.11.0 || ^0.12.0` (required by `@metamask/providers`)
  - These dependencies really should be present in projects that consume this package (e.g. MetaMask clients), and this change ensures that they now are.
  - Furthermore, we are assuming that clients already use these dependencies, since otherwise it would be impossible to consume this package in its entirety or even create a working build. Hence, the addition of these peer dependencies is really a formality and should not be breaking.
- Fix `TokensController.ignoreTokens` so that if a network is provided, `allIgnoredTokens`, `allTokens`, and `allDetectedTokens` for that network no longer get corrupted with tokens from the globally selected network ([#4967](https://github.com/MetaMask/core/pull/4967))
- Correct ESM-compatible build so that imports of the following packages that re-export other modules via `export *` are no longer corrupted: ([#5011](https://github.com/MetaMask/core/pull/5011))
  - `@metamask/abi-utils`
  - `@metamask/contract-metadata`
  - `@metamask/eth-query`
  - `@ethereumjs/util`
  - `bn.js`
  - `cockatiel`

- When the `TokenRatesController`'s subscription to `TokensController:stateChange` is fired, token prices are now updated across all chain IDs whose tokens changed, instead of just the current chain. ([#4866](https://github.com/MetaMask/core/pull/4866))
- The `TokenDetectionController` now passes a `x-metamask-clientproduct` header when calling the account API. ([#4877](https://github.com/MetaMask/core/pull/4877))

  - Those packages are now built slightly differently and are part of the [accounts monorepo](https://github.com/MetaMask/accounts).
  - Bump `@metamask/keyring-api` from `^8.1.0` to `^8.1.4`

## [38.0.1]

### Fixed

- Produce and export ESM-compatible TypeScript type declaration files in addition to CommonJS-compatible declaration files ([#4648](https://github.com/MetaMask/core/pull/4648))
  - Previously, this package shipped with only one variant of type declaration
    files, and these files were only CommonJS-compatible, and the `exports`
    field in `package.json` linked to these files. This is an anti-pattern and
    was rightfully flagged by the
    ["Are the Types Wrong?"](https://arethetypeswrong.github.io/) tool as
    ["masquerading as CJS"](https://github.com/arethetypeswrong/arethetypeswrong.github.io/blob/main/docs/problems/FalseCJS.md).
    All of the ATTW checks now pass.
- Remove chunk files. ([#4648](https://github.com/MetaMask/core/pull/4648))
  - Previously, the build tool we used to generate JavaScript files extracted
    common code to "chunk" files. While this was intended to make this package
    more tree-shakeable, it also made debugging more difficult for our
    development teams. These chunk files are no longer present.
- Don't update currency rates on transient errors ([#4662](https://github.com/MetaMask/core/pull/4662))
  - In `CurrencyRateController` if unexpected errors occur during requests to
    crypto compare, the conversion rate in state will remain unchanged instead
    of being set to null.
- Fix fallback conversion rate for token market data ([#4615](https://github.com/MetaMask/core/pull/4615))
  - On networks where the native currency is not ETH, token market data is now
    correctly priced in the native currency.

  - The index signature is restricted to the union of the enum keys of `SupportedTokenDetectionNetworks`.
  - The property value type is restricted to the type union of the addresses defined in the object.
  - The object type is constrained by `Record<Hex, string>` using the `satisfies` keyword.
- **BREAKING:** Convert the `BalanceMap` type from an `interface` into a type alias ([#4397](https://github.com/MetaMask/core/pull/4397))

  - **BREAKING:** `TokenDetectionController` now resets its polling interval to the default value of 3 minutes when token detection is triggered by external controller events `KeyringController:unlock`, `TokenListController:stateChange`, `PreferencesController:stateChange`, `AccountsController:selectedAccountChange`.
  - **BREAKING:** `TokenDetectionController` now refetches tokens on `NetworkController:networkDidChange` if the `networkClientId` is changed instead of `chainId`.
  - **BREAKING:** `TokenDetectionController` cannot initiate polling or token detection if `KeyringController` state is locked.

  - **BREAKING:** The `detectTokens` method now excludes tokens that are already included in the `TokensController`'s `detectedTokens` list from the batch of incoming tokens it sends to the `TokensController` `addDetectedTokens` method.
  - **BREAKING:** The constructor for `TokenDetectionController` expects a new required property `trackMetaMetricsEvent`, which defines the callback that is called in the `detectTokens` method.
  - **BREAKING:** In Mainnet, even if the `PreferenceController`'s `useTokenDetection` option is set to false, automatic token detection is performed on the legacy token list (token data from the contract-metadata repo).
  - **BREAKING:** The `TokensState` type is now defined as a type alias rather than an interface. ([#3690](https://github.com/MetaMask/core/pull/3690/))
    - This is breaking because it could affect how this type is used with other types, such as `Json`, which does not support TypeScript interfaces.
  - The constructor option `selectedAddress` no longer defaults to `''` if omitted. Instead, the correct address is assigned using the `AccountsController:getSelectedAccount` messenger action.

- Replace `ethereumjs-util` with `@ethereumjs/util` and `bn.js` ([#3943](https://github.com/MetaMask/core/pull/3943))
- Update `CodefiTokenPricesServiceV2` so that requests to the price API now use the `No-Cache` HTTP header ([#3939](https://github.com/MetaMask/core/pull/3939))

### Removed

- **BREAKING:** `TokenDetectionController` constructor no longer accepts options `networkClientId`, `onPreferencesStateChange`, `getPreferencesState`, `getTokensState`, or `addDetectedTokens` ([#3690](https://github.com/MetaMask/core/pull/3690), [#3775](https://github.com/MetaMask/core/pull/3775), [#3938](https://github.com/MetaMask/core/pull/3938))
- **BREAKING:** `TokenDetectionController` no longer allows the `NetworkController:stateChange` event. ([#3775](https://github.com/MetaMask/core/pull/3775))
  - The `NetworkController:networkDidChange` event can be used instead.
- **BREAKING:** `TokenDetectionController` constructor no longer accepts options `networkClientId`, `onPreferencesStateChange`, `getPreferencesState`, `getTokensState`, or `addDetectedTokens` ([#3690](https://github.com/MetaMask/core/pull/3690), [#3775](https://github.com/MetaMask/core/pull/3775), [#3938](https://github.com/MetaMask/core/pull/3938))
- **BREAKING:** `TokenBalancesController` constructor no longer accepts options `onTokensStateChange`, `getSelectedAddress` ([#3690](https://github.com/MetaMask/core/pull/3690))

### Fixed

- `TokenDetectionController.detectTokens()` now reads the chain ID keyed state properties from `TokenListController` and `TokensController` rather than incorrectly using the globally selected state properties when a network client ID is passed ([#3914](https://github.com/MetaMask/core/pull/3914))
- Fix `PreferencesController` state listener in `NftDetectionController` so that NFT detection is not run when any preference changes, but only when NFT detection is enabled ([#3917](https://github.com/MetaMask/core/pull/3917))
- Fix `isTokenListSupportedForNetwork` so that it returns false for chain 1337 ([#3777](https://github.com/MetaMask/core/pull/3777))
  - When used in combination with `TokensController`, this makes it possible to import an ERC-20 token on a locally run chain.

## [25.0.0]

### Added

- Add Linea to price api supported chains ([#3797](https://github.com/MetaMask/core/pull/3797))

### Changed

- **BREAKING:** Convert `TokenBalancesController` to `BaseControllerV2` ([#3750](https://github.com/MetaMask/core/pull/3750))
  - The constructor parameters have changed; rather than accepting a "config" parameter for interval and tokens we now pass both values as controller options, and a "state" parameter, there is now just a single object for all constructor arguments. This object has a mandatory `messenger` and an optional `state`, `tokens`, `interval` properties a disabled property has also been added.
  - State now saves tokens balances as strings and not as a BNs.
  - Additional BN export has been removed as it was intended to be removed in the next major release.
- **BREAKING:** Bump `@metamask/approval-controller` peer dependency to `^5.1.2` ([#3821](https://github.com/MetaMask/core/pull/3821))
- **BREAKING:** Bump `@metamask/network-controller` peer dependency to `^17.2.0` ([#3821](https://github.com/MetaMask/core/pull/3821))

- Bump `@metamask/base-controller` to `^4.1.1` ([#3760](https://github.com/MetaMask/core/pull/3760), [#3821](https://github.com/MetaMask/core/pull/3821))
- Bump `@metamask/controller-utils` to `^8.0.2` ([#3821](https://github.com/MetaMask/core/pull/3821))
- Bump `@metamask/polling-controller` to `^5.0.0` ([#3821](https://github.com/MetaMask/core/pull/3821))

## [24.0.0]

### Added

- Add `getDefaultTokenListState` function to `TokenListController` ([#3744](https://github.com/MetaMask/core/pull/3744))
- Add `getDefaultNftState` function to the `NftController` ([#3742](https://github.com/MetaMask/core/pull/3742))
- Add `getDefaultTokensState` function to the `TokensController` ([#3743](https://github.com/MetaMask/core/pull/3743))

### Changed

- **BREAKING:** Bump `@metamask/preferences-controller` to ^6.0.0
- Price API perf improvements ([#3753](https://github.com/MetaMask/core/pull/3753), [#3755](https://github.com/MetaMask/core/pull/3755))
  - Reduce token batch size from 100 to 30
  - Sort token addresses in query params for more cache hits

## [23.1.0]

### Added

- Add support to `CodefiTokenPricesServiceV2` for tracking degraded service ([#3691](https://github.com/MetaMask/core/pull/3691))
  - The constructor has two new options: `onDegraded` and `degradedThreshold`. `onDegraded` is an event handler for instances of degraded service (i.e. failed or slow requests), and `degradedThreshold` determines how slow a request has to be before we consider service to be degraded.

## [23.0.0]

### Added

- Add `onBreak` handler to `CodefiTokenPricesServiceV2` ([#3677](https://github.com/MetaMask/core/pull/3677))
  - This allows listening for "circuit breaks", which can indicate an outage. Useful for metrics.
- Add `fetchTokenContractExchangeRates` utility method ([#3657](https://github.com/MetaMask/core/pull/3657))
- `TokenListController` now exports a `TokenListControllerMessenger` type. ([#3609](https://github.com/MetaMask/core/pull/3609))
- `TokenDetectionController` exports types `TokenDetectionControllerMessenger`, `TokenDetectionControllerActions`, `TokenDetectionControllerGetStateAction`, `TokenDetectionControllerEvents`, `TokenDetectionControllerStateChangeEvent`. ([#3609](https://github.com/MetaMask/core/pull/3609))
- Add `enable` and `disable` methods to `TokenDetectionController`, which control whether the controller is able to make polling requests or all of its network calls are blocked.. ([#3609](https://github.com/MetaMask/core/pull/3609))
  - Note that if the controller is initiated without the `disabled` constructor option set to `false`, the `enable` method will need to be called before the controller can make polling requests in response to subscribed events.

### Changed

- **BREAKING:** Bump `@metamask/approval-controller` dependency and peer dependency from `^5.1.0` to `^5.1.1` ([#3695](https://github.com/MetaMask/core/pull/3695))
- **BREAKING:** Bump `@metamask/network-controller` dependency and peer dependency from `^17.0.0` to `^17.1.0` ([#3695](https://github.com/MetaMask/core/pull/3695))
- **BREAKING:** Bump `@metamask/preferences-controller` dependency and peer dependency from `^5.0.0` to `^5.0.1` ([#3695](https://github.com/MetaMask/core/pull/3695))
- **BREAKING:** Update `OpenSeaV2Contract` type, renaming `supply` to `total_supply` ([#3692](https://github.com/MetaMask/core/pull/3692))
- **BREAKING:** `TokenDetectionController` is upgraded to extend `BaseControllerV2` and `StaticIntervalPollingController`. ([#3609](https://github.com/MetaMask/core/pull/3609))
  - The constructor now expects an options object as its only argument, with required properties `messenger`, `networkClientId`, required callbacks `onPreferencesStateChange`, `getBalancesInSingleCall`, `addDetectedTokens`, `getTokenState`, `getPreferencesState`, and optional properties `disabled`, `interval`, `selectedAddress`.
- Bump `@metamask/base-controller` to `^4.0.1` ([#3695](https://github.com/MetaMask/core/pull/3695))
- Bump `@metamask/polling-controller` to `^4.0.0` ([#3695](https://github.com/MetaMask/core/pull/3695))
- Bump `cockatiel` from `3.1.1` to `^3.1.2` ([#3682](https://github.com/MetaMask/core/pull/3682))
- Bump `@metamask/controller-utils` from `8.0.0` to `^8.0.1` ([#3695](https://github.com/MetaMask/core/pull/3695))

### Fixed

- Fix error caused by OpenSea API rename of `supply` to `total_supply` ([#3692](https://github.com/MetaMask/core/pull/3692))
- Fix `CodefiTokenPricesServiceV2` support for Shiden ([#3683](https://github.com/MetaMask/core/pull/3683))
- Improve how `CodefiTokenPricesServiceV2` handles token price update failures ([#3687](https://github.com/MetaMask/core/pull/3687))
  - Previously a single failed token price update would prevent all other token prices from updating as well. With this update, we log and error and continue when we fail to update a token price, ensuring the others still get updated.

## [22.0.0]

### Changed

- **BREAKING:** OpenSea V2 API is used instead of V1 ([#3654](https://github.com/MetaMask/core/pull/3654))
  - `NftDetectionController` constructor now requires the `NftController.getNftApi` function.
  - NFT controllers will no longer return `last_sale` information for NFTs fetched after the OpenSea V2 update

## [21.0.0]

### Added

- Add `CodefiTokenPricesServiceV2` ([#3600](https://github.com/MetaMask/core/pull/3600), [#3655](https://github.com/MetaMask/core/pull/3655))
  - This class can be used for the new `tokenPricesService` argument for TokenRatesController. It uses a MetaMask API to fetch prices for tokens instead of CoinGecko.
  - The `CodefiTokenPricesServiceV2` will retry if the token price update fails
    - We retry each request up to 3 times using a randomized exponential backoff strategy
    - If the token price update still fails 12 times consecutively (3 update attempts, each of which has 4 calls due to retries), we stop trying for 30 minutes before we try again.
- Add polling by `networkClientId` to `AccountTrackerController` ([#3586](https://github.com/MetaMask/core/pull/3586))
  - A new state property, `accountByChainId` has been added for keeping track of account balances across chains
  - `AccountTrackerController` implements `PollingController` and can now poll by `networkClientId` via the new methods `startPollingByNetworkClientId`, `stopPollingByPollingToken`, and `stopPollingByPollingToken`.
  - `AccountTrackerController` accepts an optional `networkClientId` value on the `refresh` method
  - `AccountTrackerController` accepts an optional `networkClientId` value as the last parameter of the `syncBalanceWithAddresses` method
- Support token detection on Base and zkSync ([#3584](https://github.com/MetaMask/core/pull/3584))
- Support token detection on Arbitrum and Optimism ([#2035](https://github.com/MetaMask/core/pull/2035))

### Changed

- **BREAKING:** `TokenRatesController` now takes a required argument `tokenPricesService` ([#3600](https://github.com/MetaMask/core/pull/3600))
  - This object is responsible for fetching the prices for tokens held by this controller.
- **BREAKING:** Update signature of `TokenRatesController.updateExchangeRatesByChainId` ([#3600](https://github.com/MetaMask/core/pull/3600), [#3653](https://github.com/MetaMask/core/pull/3653))
  - Change the type of `tokenAddresses` from `string[]` to `Hex[]`
- **BREAKING:** `AccountTrackerController` constructor params object requires `getCurrentChainId` and `getNetworkClientById` hooks ([#3586](https://github.com/MetaMask/core/pull/3586))
  - These are needed for the new "polling by `networkClientId`" feature
- **BREAKING:** `AccountTrackerController` has a new required state property, `accountByChainId`([#3586](https://github.com/MetaMask/core/pull/3586))
  - This is needed to track balances accross chains. It was introduced for the "polling by `networkClientId`" feature, but is useful on its own as well.
- **BREAKING:** `AccountTrackerController` adds a mutex to `refresh` making it only possible for one call to be executed at time ([#3586](https://github.com/MetaMask/core/pull/3586))
- **BREAKING:** `TokensController.watchAsset` now performs on-chain validation of the asset's symbol and decimals, if they're defined in the contract ([#1745](https://github.com/MetaMask/core/pull/1745))
  - The `TokensController` constructor no longer accepts a `getERC20TokenName` option. It was no longer needed due to this change.
  - Add new method `_getProvider`, though this is intended for internal use and should not be called externally.
  - Additionally, if the symbol and decimals are defined in the contract, they are no longer required to be passed to `watchAsset`
- **BREAKING:** Update controllers that rely on provider to listen to `NetworkController:networkDidChange` instead of `NetworkController:stateChange` ([#3610](https://github.com/MetaMask/core/pull/3610))
  - The `networkDidChange` event is safer in cases where the provider is used because the provider is guaranteed to have been updated by the time that event is emitted. The same is not true of the `stateChange` event.
  - The following controllers now accept a `onNetworkDidChange` constructor option instead of a `onNetworkStateChange` option:
    - `TokensController`
    - `AssetsContractController`
- Update `@metamask/polling-controller` to v3 ([#3636](https://github.com/MetaMask/core/pull/3636))
  - This update adds two new methods to each polling controller: `_startPollingByNetworkClientId` and `_stopPollingByPollingTokenSetId`. These methods are intended for internal use, and should not be called directly.
  - The affected controllers are:
    - `AccountTrackerController`
    - `CurrencyRateController`
    - `NftDetectionController`
    - `TokenDetectionController`
    - `TokenListController`
    - `TokenRatesController`
- Update `@metamask/controller-utils` to v7 ([#3636](https://github.com/MetaMask/core/pull/3636))
- Update `TokenListController` to fetch prefiltered set of tokens from the API, reducing response data and removing the need for filtering logic ([#2054](https://github.com/MetaMask/core/pull/2054))
- Update `TokenRatesController` to request token rates from the Price API in batches of 100 ([#3650](https://github.com/MetaMask/core/pull/3650))
- Add dependencies `cockatiel` and `lodash` ([#3586](https://github.com/MetaMask/core/pull/3586), [#3655](https://github.com/MetaMask/core/pull/3655))

### Removed

- **BREAKING:** Remove `fetchExchangeRate` method from TokenRatesController ([#3600](https://github.com/MetaMask/core/pull/3600))
  - This method (not to be confused with `updateExchangeRate`, which is still present) was only ever intended to be used internally and should not be accessed directly.
- **BREAKING:** Remove `getChainSlug` method from TokenRatesController ([#3600](https://github.com/MetaMask/core/pull/3600))
  - This method was previously used in TokenRatesController to access the CoinGecko API. There is no equivalent.
- **BREAKING:** Remove `CoinGeckoResponse` and `CoinGeckoPlatform` types ([#3600](https://github.com/MetaMask/core/pull/3600))
  - These types were previously used in TokenRatesController to represent data returned from the CoinGecko API. There is no equivalent.
- **BREAKING:** The TokenRatesController now only supports updating and polling rates for tokens tracked by the TokensController ([#3639](https://github.com/MetaMask/core/pull/3639))
  - The `tokenAddresses` option has been removed from `startPollingByNetworkClientId`
  - The `tokenContractAddresses` option has been removed from `updateExchangeRatesByChainId`
- **BREAKING:** `TokenRatesController.fetchAndMapExchangeRates` is no longer exposed publicly ([#3621](https://github.com/MetaMask/core/pull/3621))

### Fixed

- Prevent `TokenRatesController` from making redundant token rate updates when tokens change ([#3647](https://github.com/MetaMask/core/pull/3647), [#3663](https://github.com/MetaMask/core/pull/3663))
  - Previously, token rates would be re-fetched for the globally selected network on all TokensController state changes, but now token rates are always performed for a deduplicated and normalized set of addresses, and changes to this set determine whether rates should be re-fetched.
- Prevent redundant overlapping token rate updates in `TokenRatesController` ([#3635](https://github.com/MetaMask/core/pull/3635))
- Fix `TokenRatesController` bug where the `contractExchangeRates` state would sometimes be stale after calling `updateExchangeRatesByChainId` ([#3624](https://github.com/MetaMask/core/pull/3624))
- Make `TokenRatesController.updateExchangeRatesByChainId` respect `disabled` state ([#3596](https://github.com/MetaMask/core/pull/3596))
- Fix error in `NftController` when attempt to get NFT information from on-chain fails, and ensure metadata always contains contract address and blank `name` field ([#3629](https://github.com/MetaMask/core/pull/3629))
  - When fetching on-chain NFT information fails, we now proceed with whatever we have (either the OpenSea metadata, or a blank metadata object)
  - Previously, if we were unable to retrieve NFT metadata from on-chain or OpenSea, the returned NFT metadata would be missing a `name` field and the contract address. Now the returned metadata always has those entries, though the `name` is set to `null`.
  - This affects `watchNft` and `addNft` methods

## [20.0.0]

### Added

- **BREAKING**: `TokenRatesControllerState` now has required `contractExchangeRatesByChainId` property which an object keyed by `chainId` and `nativeCurrency` ([#2015](https://github.com/MetaMask/core/pull/2015))
- **BREAKING**: `TokenRatesController` constructor params now requires `getNetworkClientById` ([#2015](https://github.com/MetaMask/core/pull/2015))
- Add types `CurrencyRateControllerEvents` and `CurrencyRateControllerActions` ([#2029](https://github.com/MetaMask/core/pull/2029))
- Add polling-related methods to TokenRatesController ([#2015](https://github.com/MetaMask/core/pull/2015))
  - `startPollingByNetworkClientId`
  - `stopPollingByPollingToken`
  - `stopAllPolling`
  - `_executePoll`
- Add `updateExchangeRatesByChainId` method to TokenRatesController ([#2015](https://github.com/MetaMask/core/pull/2015))
  - This is a lower-level version of `updateExchangeRates` that takes chain ID, native currency, and token addresses.
- `TokenRatesController` constructor params now accepts optional `interval` and `threshold` ([#2015](https://github.com/MetaMask/core/pull/2015))
- `TokenRatesController.fetchExchangeRate()` now accepts an optional `tokenAddresses` as the last parameter ([#2015](https://github.com/MetaMask/core/pull/2015))
- `TokenRatesController.getChainSlug()` now accepts an optional `chainId` parameter ([#2015](https://github.com/MetaMask/core/pull/2015))
- `TokenRatesController.fetchAndMapExchangeRates()` now accepts an optional `tokenAddresses` as the last parameter ([#2015](https://github.com/MetaMask/core/pull/2015))

### Changed

- **BREAKING:** Bump dependency on `@metamask/base-controller` to ^4.0.0 ([#2063](https://github.com/MetaMask/core/pull/2063))
  - This is breaking because the type of the `messenger` has backward-incompatible changes. See the changelog for this package for more.
- Bump `@metamask/approval-controller` to ^5.0.0 ([#2063](https://github.com/MetaMask/core/pull/2063))
- Bump `@metamask/controller-utils` to ^6.0.0 ([#2063](https://github.com/MetaMask/core/pull/2063))
- Bump `@metamask/network-controller` to ^17.0.0 ([#2063](https://github.com/MetaMask/core/pull/2063))
- Bump `@metamask/polling-controller` to ^2.0.0 ([#2063](https://github.com/MetaMask/core/pull/2063))
- Bump `@metamask/preferences-controller` to ^5.0.0 ([#2063](https://github.com/MetaMask/core/pull/2063))

## [19.0.0]

### Changed

- **BREAKING:** Bump dependency and peer dependency on `@metamask/network-controller` to ^16.0.0
- Add optional `networkClientId` and `userAddress` args to remaining `NftController` public methods ([#2006](https://github.com/MetaMask/core/pull/2006))
  - `watchNft`, `removeNft`, `removeAndIgnoreNft`, `removeNftContract`, `updateNftFavoriteStatus`, and `checkAndUpdateAllNftsOwnershipStatus` methods on `NftController` all now accept an optional options object argument containing `networkClientId` and `userAddress` to identify where in state to mutate.
  - **BREAKING**: `addNft` no longer accepts a `chainId` property in its options argument since this value can be retrieved by the `networkClientId` property and is therefore redundant.
  - **BREAKING**: The third and fourth arguments on NftController's `addNftVerifyOwnership` method, have been replaced with an options object containing optional properties `networkClientId`, `userAddress` and `source`. This method signature is more aligned with the options pattern for passing `networkClientId` and `userAddress` on this controller and elsewhere.
  - **BREAKING**: `checkAndUpdateSingleNftOwnershipStatus` on NftController no longer accepts a `chainId` in its options argument. This is replaced with an optional `networkClientId` property which can be used to fetch chainId.
    **\*BREAKING**: The fourth argument of the `isNftOwner` method on `NftController` is now an options object with an optional `networkClientId` property. This method signature is more aligned with the options pattern for passing `networkClientId` on this controller and elsewhere.
  - **BREAKING**: `validateWatchNft` method on `NftController` is now private.
  - **BREAKING**: `detectNfts` on `NftDetectionController` now accepts a single object argument with optional properties `networkClientId` and `userAddress`, rather than taking these as two sequential arguments.
- Bump dependency `@metamask/eth-query` from ^3.0.1 to ^4.0.0 ([#2028](https://github.com/MetaMask/core/pull/2028))
- Bump dependency on `@metamask/polling-controller` to ^1.0.2
- Bump `@metamask/utils` from 8.1.0 to 8.2.0 ([#1957](https://github.com/MetaMask/core/pull/1957))

### Fixed

- Add name and symbol to the payload returned by the `ERC1155Standard` class `getDetails` method for `ERC1155` contracts ([#1727](https://github.com/MetaMask/core/pull/1727))

## [18.0.0]

### Changed

- **BREAKING**: `CurrencyRateController` is now keyed by `nativeCurrency` (i.e. ticker) for `conversionDate`, `conversionRate`, and `usdConversionRate` in the `currencyRates` object. `nativeCurrency`, `pendingNativeCurrency`, and `pendingCurrentCurrency` have been removed.
  - ```
    export type CurrencyRateState = {
      currentCurrency: string;
      currencyRates: Record<
        string, // nativeCurrency
        {
          conversionDate: number | null;
          conversionRate: number | null;
          usdConversionRate: number | null;
        }
      >;
    };
    ```
- **BREAKING**: `CurrencyRateController` now extends `PollingController` ([#1805](https://github.com/MetaMask/core/pull/1805))
  - `start()` and `stop()` methods replaced with `startPollingByNetworkClientId()`, `stopPollingByPollingToken()`, and `stopAllPolling()`
- **BREAKING:** `CurrencyRateController` now sends the `NetworkController:getNetworkClientById` action via messaging controller ([#1805](https://github.com/MetaMask/core/pull/1805))

### Fixed

- Parallelize network requests in assets controllers for performance enhancement ([#1801](https://github.com/MetaMask/core/pull/1801))
- Fix token detection on accounts when user changes account after token detection request is inflight ([#1848](https://github.com/MetaMask/core/pull/1848))

## [17.0.0]

### Changed

- Bump dependency and peer dependency on `@metamask/preferences-controller` to ^4.4.3
- Fix support for NFT metadata stored outside IPFS ([#1772](https://github.com/MetaMask/core/pull/1772))

## [15.0.0]

### Changed

- **BREAKING**: `NftController` now expects `getNetworkClientById` in constructor options ([#1698](https://github.com/MetaMask/core/pull/1698))
- **BREAKING**: `NftController.addNft` function signature has changed ([#1698](https://github.com/MetaMask/core/pull/1698))
  - Previously
    ```

      source?: Source;
      networkClientId?: NetworkClientId; // new
    },
    ```
- `NftController.addNftVerifyOwnership`: Now accepts optional 3rd argument `networkClientId` which is used to fetch NFT metadata and determine by which chainId the added NFT should be stored in state.

### Added

- The method `getERC20TokenName` has been added to `AssetsContractController` ([#1127](https://github.com/MetaMask/core/pull/1127))
  - This method gets the token name from the token contract

### Changed

- **BREAKING:** The tokens controller now requires `onTokenListStateChange` and `getERC20TokenName` as constructor parameters ([#1127](https://github.com/MetaMask/core/pull/1127))
  - The `getERC20TokenName` method is used to get the token name for tokens added via `wallet_watchAsset`
  - The `onTokenListStateChange` method is used to trigger a name update when the token list changes. On each change, token names are copied from the token list if they're missing from token controller state.
- **BREAKING:** The signature of the tokens controller method `addToken` has changed
  - The fourth and fifth positional parameters (`image` and `interactingAddress`) have been replaced by an `options` object
  - The new options parameter includes the `image` and `interactingAddress` properties, and a new `name` property

## [9.1.0]

### Added

- Add a fifth argument, `source`, to NftController's `addNft` method ([#1417](https://github.com/MetaMask/core/pull/1417))
  - This argument can be used to specify whether the NFT was detected, added manually, or suggested by a dapp

### Fixed

- Fix `watchNft` in NftController to ensure that if the network changes before the user accepts the request, the NFT is added to the chain ID and address before the request was initiated ([#1417](https://github.com/MetaMask/core/pull/1417))

## [9.0.0]

### Added

- **BREAKING**: Add required options `getSelectedAddress` and `getMultiAccountBalancesEnabled` to AccountTrackerController constructor and make use of them when refreshing account balances ([#1146](https://github.com/MetaMask/core/pull/1146))
  - Previously, the controller would refresh all account balances, but these options can be used to only refresh the currently selected account
- **BREAKING:** Add logic to support validating and adding ERC721 and ERC1155 tokens to NFTController state via `wallet_watchAsset` API. ([#1173](https://github.com/MetaMask/core/pull/1173), [#1406](https://github.com/MetaMask/core/pull/1406))
  - The `NFTController` now has a new `watchNFT` method that can be called to send a message to the `ApprovalController` and prompt the user to add an NFT to their wallet state.
  - The `NFTController` now requires an instance of a ControllerMessenger to be passed to its constructor. This is messenger is used to pass the `watchNFT` message to the `ApprovalController`.

### Changed

- Add dependency on `@ethersproject/address` ([#1173](https://github.com/MetaMask/core/pull/1173))
- Replace `eth-rpc-errors` with `@metamask/rpc-errors` ([#1173](https://github.com/MetaMask/core/pull/1173))

- Enable token detection for the Aurora network ([#1327](https://github.com/MetaMask/core/pull/1327))

### Changed

- **BREAKING:** Bump to Node 16 ([#1262](https://github.com/MetaMask/core/pull/1262))
- **BREAKING:** Change format of chain ID in state to 0x-prefixed hex string ([#1367](https://github.com/MetaMask/core/pull/1367))

  - The NFT controller state properties `allNftContracts` and `allNfts` are now keyed by address and `Hex` chain ID, rather than by address and decimal `string` chain ID
    - This requires a state migration
  - The NFT detection controller now expects the `chainId` configuration entry and constructor parameter as type `Hex` rather than decimal `string`
  - The token detection controller now expects the `chainId` configuration entry as type `Hex` rather than decimal `string`
  - The token list controller now expects the `chainId` constructor parameter as type `Hex` rather than decimal `string`
  - The token list controller state property `tokensChainsCache` is now keyed by `Hex` chain ID rather than by decimal `string` chain ID.
    - This requires a state migration
  - The token rates controller now expects the `chainId` configuration entry and constructor parameter as type `Hex` rather than decimal `string`
  - The token rates controller `chainId` setter now expects the chain ID as `Hex` rather than as a decimal string
  - The tokens controller now expects the `chainId` configuration entry and constructor parameter as type `Hex` rather than decimal `string`
  - The tokens controller `addDetectedTokens` method now accepts the `chainId` property of the `detectionDetails` parameter to be of type `Hex` rather than decimal `string`.
  - The tokens controller state properties `allTokens`, `allIgnoredTokens`, and `allDetectedTokens` are now keyed by chain ID in `Hex` format rather than decimal `string`.
    - This requires a state migration
- **BREAKING:** Use approval controller for suggested assets ([#1261](https://github.com/MetaMask/core/pull/1261), [#1268](https://github.com/MetaMask/core/pull/1268))
  - The actions `ApprovalController:acceptRequest` and `ApprovalController:rejectRequest` are no longer required by the token controller messenger.
  - The `suggestedAssets` state has been removed, which means that suggested assets are no longer persisted in state
  - The return type for `watchAsset` has changed. It now returns a Promise that settles after the request has been confirmed or rejected.
- **BREAKING:** Initialize controllers with the current network ([#1361](https://github.com/MetaMask/core/pull/1361))

    - `AssetsContractController`
    - `NftController`
    - `NftDetectionController`
    - `TokenRatesController`
    - `TokensController`
- **BREAKING:** The token list controller messenger requires the `NetworkController:stateChange` event instead of the `NetworkController:providerConfigChange` event ([#1329](https://github.com/MetaMask/core/pull/1329))
- **BREAKING:** The token list controller `onNetworkStateChange` option now has a more restrictive type ([#1329](https://github.com/MetaMask/core/pull/1329))
  - The event handler parameter type has been changed from `NetworkState | ProviderConfig` to `NetworkState`
- **BREAKING:** Update the account tracker controller `provider` type ([#1266](https://github.com/MetaMask/core/pull/1266))

- **BREAKING:** Update`@metamask/preferences-controller` dependency and add it as a peer dependency ([#1393](https://github.com/MetaMask/core/pull/1393))
- **BREAKING:** Update `@metamask/approval-controller` and `@metamask/network-controller` dependencies and peer dependencies
- Bump @metamask/abi-utils from 1.1.0 to 1.2.0 ([#1287](https://github.com/MetaMask/core/pull/1287))

## [5.1.0]

### Added

- Support watching assets on a specific account ([#1124](https://github.com/MetaMask/core/pull/1124))

## [5.0.1]

### Changed

- Update `@metamask/contract-metadata` from 2.1.0 to 2.3.1 ([#1141](https://github.com/MetaMask/core/pull/1141))

## [5.0.0]

- **BREAKING:** Remove `isomorphic-fetch` ([#1106](https://github.com/MetaMask/controllers/pull/1106))
  - Consumers must now import `isomorphic-fetch` or another polyfill themselves if they are running in an environment without `fetch`

## [4.0.1]

### Fixed

- Update Nft Controller to add the NFT back to its own group if we are re-importing it ([#1082](https://github.com/MetaMask/core/pull/1082))

## [4.0.0]

### Added

- Add Sepolia support to the currency rate controller ([#1041](https://github.com/MetaMask/controllers/pull/1041))

## [3.0.0]

### Changed

- **BREAKING:** A new private property, controlled by the `start` and `stop` methods, is added to the CurrencyRateController: `enabled`. When this is false, no network requests will be made from the controller. Previously, setNativeCurrency or setCurrentCurrency would trigger a network request. That is now prevented if `enabled` is false. ([#1002](https://github.com/MetaMask/core/pull/1002))

### Fixed

- The TokenRatesController no longer overwrites the `disabled` config property passed to the constructor, allowing the controller to be instantiated with `config.disabled` set to either true or false. ([#1002](https://github.com/MetaMask/core/pull/1002))
- This package will now warn if a required package is not present ([#1003](https://github.com/MetaMask/core/pull/1003))

    - NftController
    - NftDetectionController
    - TokenDetectionController
    - TokenListController
    - TokenRatesController
    - TokenController
- **BREAKING:** [TokenDetectionController] Update `getNetworkState` constructor option to take an object with `providerConfig` property rather than `providerConfig` ([#995](https://github.com/MetaMask/core/pull/995))
- Relax dependencies on `@metamask/base-controller`, `@metamask/controller-utils`, `@metamask/network-controller`, and `@metamask/preferences-controller` (use `^` instead of `~`) ([#998](https://github.com/MetaMask/core/pull/998))

## [1.0.1]

### Fixed

- Fix race condition where some token detections can get mistakenly added to the wrong account ([#956](https://github.com/MetaMask/core/pull/956))

## [1.0.0]

### Added

- Initial release
  - As a result of converting our shared controllers repo into a monorepo ([#831](https://github.com/MetaMask/core/pull/831)), we've created this package from select parts of [`@metamask/controllers` v33.0.0](https://github.com/MetaMask/core/tree/v33.0.0), namely:
    - Everything in `src/assets`
    - Asset-related functions from `src/util.ts` and accompanying tests

    All changes listed after this point were applied to this package following the monorepo conversion.

### Changed

- Use Ethers for AssetsContractController ([#845](https://github.com/MetaMask/core/pull/845))
