 ### Changed
 
 - Bump `@metamask/account-tree-controller` from `^7.5.3` to `7.5.4` ([#9429](https://github.com/MetaMask/core/pull/9429))
-- Gate HIP-3 markets to USDC collateral only, following HyperLiquid's USDH sunset (TAT-3304)
+- Gate HIP-3 markets to USDC collateral only, following HyperLiquid's USDH sunset (TAT-3304) ([#9530](https://github.com/MetaMask/core/pull/9530))
   - Market discovery (`getMarkets`) now filters a HIP-3 DEX out entirely when its collateral token positively resolves to something other than USDC, so such a market can never be surfaced to trade, even via an allowlist entry naming the DEX.
   - Placing an order on a non-USDC-collateral HIP-3 DEX now fails immediately with a new `UNSUPPORTED_COLLATERAL` error code instead of attempting the previous USDC→USDH auto-swap path.
   - The collateral check fails open (treats the DEX as USDC-collateral) when the collateral token can't be resolved against spot metadata, so incomplete metadata doesn't spuriously block an otherwise-valid market.
   - Removed the now-unreachable USDH auto-swap machinery this replaces (spot USDH/USDC balance lookups, the USDC→USDH spot swap, and the auto-swap orchestration).
-- Subscribe to HyperLiquid's `fastAssetCtxs` WebSocket feed for mark/mid price updates, replacing `assetCtxs` as the latency-sensitive price source now that HyperLiquid has slowed the public `assetCtxs` feed cadence
+- Subscribe to HyperLiquid's `fastAssetCtxs` WebSocket feed for mark/mid price updates, replacing `assetCtxs` as the latency-sensitive price source now that HyperLiquid has slowed the public `assetCtxs` feed cadence ([#9530](https://github.com/MetaMask/core/pull/9530))
   - `assetCtxs` continues to populate funding, open interest, volume, and oracle price data, and remains the price source for any symbol `fastAssetCtxs` doesn't cover.
   - `fastAssetCtxs` is a single global subscription (the HyperLiquid SDK exposes no per-DEX variant): the first message is a full snapshot keyed by coin, and later messages contain diffs for only the coins that changed. Coins without an active price subscriber are ignored.
   - Established alongside the global `allMids` subscription, restored together on WebSocket reconnect, and torn down on `clearAll()`. Subscribe attempts use the same 3-attempt/500ms-backoff retry as `assetCtxs` for transient SDK errors.
 
 ### Removed
 
-- **BREAKING:** Remove the `USDH_CONFIG` export, following HyperLiquid's USDH sunset (TAT-3304)
+- **BREAKING:** Remove the `USDH_CONFIG` export, following HyperLiquid's USDH sunset (TAT-3304) ([#9530](https://github.com/MetaMask/core/pull/9530))
   - This constant configured the now-removed USDC→USDH auto-swap path; consumers importing it should remove the reference, as USDH-collateral HIP-3 DEXs are no longer supported (see the collateral gating change above).
 
 ### Fixed
 
-- Scope `#notifyAllPriceSubscribers` to the symbols that actually changed, instead of always fanning out to every price subscriber
+- Scope `#notifyAllPriceSubscribers` to the symbols that actually changed, instead of always fanning out to every price subscriber ([#9530](https://github.com/MetaMask/core/pull/9530))
   - The `allMids` handler now tracks a per-symbol `changedSymbols` set (replacing the previous all-or-nothing `hasUpdates` boolean) and only notifies subscribers of symbols whose price changed.
   - The `activeAssetCtx` handler now notifies only the subscribers of the symbol it just updated, instead of re-notifying every subscribed symbol on each tick.
   - This eliminates redundant reference-equal `PriceUpdate` deliveries to list-view subscribers (e.g. market overview, watchlist) whenever an unrelated symbol's fast-stream price ticks.
