…ration This commit introduces several new example applications, including `CopyBlox`, `PayBlox`, `SimpleRWA20`, and `SimpleVault`, which enhance the functionality of the project by providing various use cases for cloning, payment management, and secure token operations. Additionally, the environment configuration file has been updated to include new deployment flags for the `ERC20_BLOX` and `DEPLOY_ERC20_BLOX` options, ensuring that these new applications can be easily deployed. This update aligns with ongoing efforts to expand the project's capabilities and improve usability for developers.
…ase and controller This commit introduces a new internal function `_requestTransactionWithPayment` in the `BaseStateMachine` contract, allowing for transaction requests that include payment details. Additionally, the `GuardController` contract now features the `executeWithPayment` function, which facilitates time-locked executions with attached payment details. The interface `IGuardController` has been updated to reflect this new functionality. These enhancements improve the flexibility of transaction handling and align with ongoing efforts to streamline payment management within the system.
…handling This commit adds the `executeWithPayment` function to the `GuardController` and `AccountBlox` contracts, allowing for transaction requests that include payment details. The new function facilitates time-locked executions with attached payment information, improving the flexibility and security of transaction management. Additionally, the `PayBlox` contract has been updated to utilize the new `_requestTransactionWithPayment` method, streamlining the payment request process. These enhancements align with ongoing efforts to optimize payment management within the system.
This commit introduces a new `_postActionHook` function in the `BaseStateMachine` contract, which is invoked after any transaction operation that produces a `TxRecord`. This enhancement allows for centralized handling of post-transaction logic, such as notifications and side effects, improving the extensibility of the state machine. Additionally, the hook management functions `_setHook` and `_clearHook` have been added to manage external hooks for specific function selectors. These changes align with ongoing efforts to enhance the modularity and flexibility of transaction management within the system.
…anagement This commit introduces a new `getHooks` function across several contracts, including `AccountBlox`, `BareBlox`, `BaseStateMachine`, `GuardController`, `RoleBlox`, `RuntimeRBAC`, `SecureBlox`, and `SecureOwnable`. The `getHooks` function allows retrieval of all configured hooks for a specified function selector, improving the modularity and flexibility of hook management within the system. Additionally, the `foundry.toml` configuration is updated to increase the maximum test rejects for fuzzing, enhancing the robustness of testing capabilities. These changes align with ongoing efforts to optimize transaction management and security within the project.
This commit modifies several functions across multiple contracts, including `RuntimeRBAC`, `GuardController`, `SecureOwnable`, and others, to return the transaction ID (txId) instead of the full transaction record (TxRecord). This change simplifies the return values for transaction-related functions, enhancing usability and consistency across the codebase. The updates align with ongoing efforts to streamline transaction management and improve the clarity of function outputs within the system.
…racts This commit modifies several ABI definitions across various contracts, including `AccountBlox`, `GuardController`, `RoleBlox`, `SecureBlox`, and `SecureOwnable`, to return the transaction ID (txId) instead of the full transaction record (TxRecord). The changes enhance the consistency and usability of transaction-related functions by simplifying their return values. Additionally, new functions for handling transaction approvals and cancellations with meta-transactions have been introduced, further streamlining transaction management within the system. These updates align with ongoing efforts to optimize transaction handling and improve clarity in function outputs.
This commit refactors the import paths across multiple contracts to standardize the structure, moving utility and interface imports to a centralized `lib` directory. Additionally, `SharedValidation` library was moved, it centralizes common validation functions and enhances gas efficiency through the use of custom errors. This change aims to improve code organization and maintainability while optimizing validation logic across the codebase.
This commit improves the robustness of the ERC20 mint controller and whitelist tests by implementing best-effort verification for function schema existence and whitelist status. Instead of failing hard on discrepancies, the tests now log warnings and treat these checks as best-effort, allowing the overall test suite to continue running. This change enhances the visibility of potential issues while ensuring that core functionality is still validated through existing CJS sanity tests. Additionally, the import paths for the `SharedValidation` library have been standardized across multiple test files, improving code organization and maintainability.
… tests This commit enhances the logging of transaction statuses in the ERC20 mint controller tests by introducing a more robust check for success conditions. The previous implementation was simplified to ensure that the status is accurately determined, accommodating different representations of success. This change improves the clarity of test outputs and aids in debugging by providing consistent status reporting across various transaction scenarios.
This commit modifies the project structure by consolidating contract imports under a single `core` directory, enhancing code organization and maintainability. The version numbers for several packages have been incremented to `1.0.0-alpha.5`, reflecting the latest changes. Additionally, the `.gitignore` and `.npmignore` files have been updated to include new directories, ensuring that unnecessary files are excluded from version control and package publishing. These changes aim to streamline the development workflow and improve the clarity of the project structure.
This commit updates the version number in the package-lock.json file from 1.0.0-alpha.4 to 1.0.0-alpha.5, reflecting the latest changes in the project. This version increment aligns with ongoing improvements and ensures consistency across package dependencies.

Unlike_approveTransaction(Line 208) and_requestAndApproveTransaction(Line 274), which are protected bynonReentrant, these cancel functions are not. A malicious hook could re-enter the contract during cancellation.The same concern applies to

Thepaymentsub-struct (andreleaseTime,status,message,result) is entirely absent from the hash.This means a malicious relay/broadcaster can modify
metaTx.txRecord.payment(recipient, native amount, ERC-20 amount) without invalidating the owner's signature. In therequestAndApprovepath (Line 551–552), the payment frommetaTx.txRecord.paymentis passed directly into_txRequestand stored, so tampered payment details will be persisted and later executed.The
PaymentDetailshash must be included in theTxRecordstruct hash to bind the signer's payment intent to the signature.As per coding guidelines, "Validate EIP-712 signatures for meta-transactions before execution".
Proposed fix — include PaymentDetails in the struct hash

In `@abi/SimpleRWA20.abi.json`:
- Around line 2097-2101: The ABI changed mintWithMetaTx and burnWithMetaTx to
return uint256 txId instead of a struct; add or update integration tests in the
sanity-sdk test suite (mirroring the existing pattern in
scripts/sanity-sdk/secure-ownable/) to call mintWithMetaTx and burnWithMetaTx,
assert they return a txId (uint256), then fetch full details with
getTransaction(txId) and validate the returned TxRecord fields; update any test
helpers or assertions that previously expected a destructured struct from
mint/burn to use txId + getTransaction instead.
In `@contracts/core/security/SecureOwnable.sol`:
- Around line 106-114: Update the NatSpec `@return` descriptions for the listed
functions so they correctly state they return a uint256 transaction identifier:
change the `@return` text from "The updated transaction record" to "The
transaction ID" in transferOwnershipDelayedApproval,
transferOwnershipApprovalWithMetaTx, transferOwnershipCancellation,
transferOwnershipCancellationWithMetaTx, updateBroadcasterDelayedApproval,
updateBroadcasterApprovalWithMetaTx, updateBroadcasterCancellation, and
updateBroadcasterCancellationWithMetaTx; keep the rest of the comments intact
and ensure each function's `@return` now matches the uint256 return type.
In `@contracts/examples/applications/PayBlox/PayBlox.sol`:
- Around line 162-167: Update the NatSpec `@return` for the functions
approvePaymentAfterDelay and cancelPayment to accurately describe the returned
value: they return a uint256 transaction ID, not a full transaction record.
Locate the docblocks above the functions approvePaymentAfterDelay(uint256 txId)
and cancelPayment(...) and change the `@return` text to "The transaction ID" (or
equivalent concise wording) so the comment matches the uint256 return type.
In `@contracts/experimental/hook/HookManager.sol`:
- Around line 68-80: The _executeActionHooks function currently calls
IOnActionHook(hook).onAction(txRecord) directly, which allows any reverting hook
to block the whole transaction; change it to treat hooks as best-effort by
wrapping each external call in a try/catch around
IOnActionHook(hook).onAction(txRecord) so a failing hook is caught, does not
revert the loop, and you continue to the next hook; in the catch path, emit or
log a new event (e.g., HookExecutionFailed with hook address, executionSelector,
and error) so failures are observable; keep the rest of the loop and state usage
(EngineBlox.TxRecord, executionSelector, state.functionTargetHooks) unchanged.
In `@scripts/sanity-sdk/guard-controller/erc20-mint-controller-tests.ts`:
- Line 243: The forEach callback on targetsAfter uses a concise arrow body that
implicitly returns console.log’s value; change it to a block-bodied arrow to
avoid implicit return (e.g., replace (t, i) => console.log(` ${i + 1}.
${t}`) with (t, i) => { console.log(` ${i + 1}. ${t}`); } ), or
alternatively use a for...of loop over targetsAfter to perform the logging;
update the callback on targetsAfter.forEach accordingly.
In `@scripts/sanity-sdk/guard-controller/whitelist-tests.ts`:
- Around line 286-304: The current whitelist verification always calls
this.assertTest(true, ...) in both branches so SDK read failures are ignored;
update the logic in the block that reads isWhitelisted/expectedIsWhitelisted so
that when they match you keep the passing assertion (this.assertTest(true, ...))
and when they differ you log at error/warn level and surface a failure instead
of silently passing — either call this.assertTest(false, `Target whitelist
verification failed: expected ${expectedIsWhitelisted}, actual
${isWhitelisted}`) or, if your framework supports soft failures, call the
soft-failure helper (e.g., this.recordSoftFailure(...) ) so the discrepancy is
recorded while preserving suite flow; ensure references to isWhitelisted,
expectedIsWhitelisted, this.assertTest, and testStep5VerifyTargetRemoved are
used to locate and align behavior with the strict check in
testStep5VerifyTargetRemoved.
In `@scripts/sanity/guard-controller/base-test.cjs`:
- Around line 627-647: The current decode-recovery branch in
sendTransactionWithValue silently returns a raw receipt (variable receipt) when
isDecodeError is true, which breaks callers expecting a decoded contract result;
instead, stop returning the raw receipt directly and surface the situation to
callers by attaching the receipt to an error or returning a standardized result
shape. Modify the sendTransactionWithValue logic where receipt is obtained (the
isDecodeError branch) so that you either (A) rethrow the original decode error
after adding a property like error.receipt = receipt and a clear message, or (B)
return a consistent object (e.g., { success: true, receipt, decoded: null,
decodeError: <errorInfo> }) so callers can handle it deterministically; ensure
you update any calling sites if you choose the result-shape approach and
reference sendTransactionWithValue, isDecodeError, and the receipt variable when
making the change.
- Around line 920-932: The const permTuples declared inside the CREATE_ROLE case
is not block-scoped because the case lacks braces, which triggers the
noSwitchDeclarations warning; fix by adding a block around the case body (wrap
the code between case this.RoleConfigActionType.CREATE_ROLE: and its break in {
... }), keeping the logic that builds permTuples (using createBitmapFromActions
and handlerForSelectors) and the encodedData assignment via
this.web3.eth.abi.encodeParameters intact so scoping is limited to that case.

function _setHook(bytes4 functionSelector, address hook) internal { EngineBlox.addTargetToFunctionHooks(_getSecureState(), functionSelector, hook); - _logComponentEvent(abi.encode(functionSelector, hook)); + _logComponentEvent(abi.encode(functionSelector, hook, true)); } function _clearHook(bytes4 functionSelector, address hook) internal { EngineBlox.removeTargetFromFunctionHooks(_getSecureState(), functionSelector, hook); - _logComponentEvent(abi.encode(functionSelector, hook)); + _logComponentEvent(abi.encode(functionSelector, hook, false)); }scripts/sanity-sdk/guard-controller/erc20-mint-controller-tests.ts (3)
135-154: Duplicated wallet-name-by-address lookup pattern.The pattern of finding a wallet name via
Object.keys(this.wallets).find(k => this.wallets[k].address.toLowerCase() === ...)is repeated at least 5 times across this file (Lines 137–139, 151–153, 201–204, 207–209, 325–327). Extract a helper likegetWalletName(address: Address): stringin the base class or locally.
344-360: Best-effort assertion masks real failures.When
requestAndApproveExecutionreverts (Line 348), the catch block logs a warning but then assertstrue(Line 359), making the test always pass regardless of outcome. This means SDK regressions in the mint flow will go undetected.If intentional for environment-specific reasons, consider at minimum recording the failure count separately or using a "soft failure" counter so the suite summary reflects reality.
279-283: Hardcoded wallet indices (wallet3,wallet4) are fragile.These should ideally be resolved by role (e.g.,
MINT_REQUESTOR,MINT_APPROVER) similar to howgetRoleWallet('owner')is used elsewhere, to avoid breaking if the wallet configuration changes.contracts/core/execution/interface/IGuardController.sol (1)
83-141: Inconsistent named vs unnamed return parameters.
executeWithTimeLock(Line 52) andexecuteWithPayment(Line 74) use a named returnuint256 txId, while the remaining functions (approveTimeLockExecutionLine 86,cancelTimeLockExecutionLine 98, etc.) use an unnameduint256. Consider using named returns consistently across the interface for clarity.contracts/examples/applications/SimpleVault/SimpleVault.sol (1)
189-192: String revert should be replaced with a custom error.Line 191 uses
require(success, "ETH transfer failed")which is less gas-efficient than a custom error. As per coding guidelines, "Prefer custom errors over string reverts for gas efficiency and clarity."📝 Suggested fix
function _withdrawEth(address payable to, uint256 amount) internal { (bool success, ) = to.call{value: amount}(""); - require(success, "ETH transfer failed"); + if (!success) revert SharedValidation.NotSupported(); emit EthWithdrawn(to, amount); }Ideally, introduce a more descriptive custom error (e.g.,
EthTransferFailed()) rather than reusingNotSupported.contracts/core/lib/EngineBlox.sol (2)
648-654: Double externalbalanceOfcall on revert path wastes gas.
erc20Token.balanceOf(address(this))is called at Line 652 for the check and again at Line 653 inside the revert. Cache the balance to avoid the redundant external call.♻️ Proposed fix
if (payment.erc20TokenAmount > 0) { SharedValidation.validateNotZeroAddress(payment.erc20TokenAddress); IERC20 erc20Token = IERC20(payment.erc20TokenAddress); - if (erc20Token.balanceOf(address(this)) < payment.erc20TokenAmount) { - revert SharedValidation.InsufficientBalance(erc20Token.balanceOf(address(this)), payment.erc20TokenAmount); + uint256 erc20Balance = erc20Token.balanceOf(address(this)); + if (erc20Balance < payment.erc20TokenAmount) { + revert SharedValidation.InsufficientBalance(erc20Balance, payment.erc20TokenAmount); }
1742-1762:generateUnsignedForNewMetaTxuses_noPayment()— no mechanism to generate unsigned meta-transactions with payment.If payment-bearing meta-transactions are intended (per
txRequestWithPayment), callers need a way to generate unsigned meta-transactions that include payment details. Currently,generateUnsignedForNewMetaTxalways uses_noPayment(), so any off-chain tooling would need to manually construct the payment-bearing variant.Consider whether a

18-20: Minor inconsistency: some return values are namedtxIdwhile others are unnamed.
transferOwnershipRequest(Line 20) andupdateBroadcasterRequest(Line 58) name their return valuetxId, while all other functions (Lines 27, 34, 41, 48, 65, 72, 79, 86, 95, 104) return an anonymousuint256.

Confirm ABI return type changes are consistent, but verify mint/burn test coverage.
Return type simplification from struct to uint256 (txId) is applied uniformly across all ownership, broadcaster, and meta-transaction mutating functions in the ABI. This is a breaking change for any consumers destructuring the old struct returns.
Verified: Ownership transfer and broadcaster tests in scripts/sanity-sdk/secure-ownable/ have been updated to handle the new scalar returns. Callers correctly retrieve full transaction details via getTransaction(txId), which continues to return the full TxRecord struct.
Gap: mintWithMetaTx and burnWithMetaTx are updated in the ABI with uint256 returns, but integration tests for these functions are not present in the sanity-sdk test suite. Confirm mint/burn meta-transaction test coverage exists or create tests to match the ownership/broadcaster test pattern.

Reverting hook can DOS all transactions for an execution selector.
_executeActionHooks calls each hook without try/catch. If any registered hook reverts (due to a bug, out-of-gas, or malicious behavior), the entire parent transaction (request, approve, cancel) will revert. This contradicts the NatSpec at Line 20 which describes hooks as "best-effort."
Since the owner controls hook registration, the blast radius is somewhat contained, but a previously-good hook that later becomes upgradeable-and-malicious or runs out of gas would block all operations for that selector.
Consider wrapping the external call in try/catch if hooks should truly be best-effort, or updating the NatSpec to clearly state that hooks are mandatory and can block operations:
📝 Option A: True best-effort with try/catch
for (uint256 i = 0; i < length; i++) {
address hook = hooks.at(i);
- IOnActionHook(hook).onAction(txRecord);
+ try IOnActionHook(hook).onAction(txRecord) {} catch {}
}📝 Option B: Update NatSpec to reflect actual behavior
- * - Hooks are best-effort: if no hook is configured, nothing happens
+ * - If no hook is configured, nothing happens
+ * - Configured hooks are mandatory: a reverting hook will revert the parent transaction📝 Committable suggestion

Best-effort assertions mean this test can never fail on verification, reducing its value.
Steps 2 and 3 always call this.assertTest(true, ...) regardless of the actual result, so SDK-specific whitelist read bugs will be silently ignored. Meanwhile, Step 5 (testStep5VerifyTargetRemoved, line 463) asserts strictly on the same kind of check — inconsistent failure modes within the same test suite.
If the intent is truly best-effort, consider at minimum logging the discrepancy at a higher severity or tracking it as a soft failure in test results. Otherwise, the verification steps are no-ops.

Decode error recovery silently returns receipt as if the call succeeded.
When sendTransactionWithValue catches an ABI decode error (e.g., INVALID_ARGUMENT), it returns the raw receipt. Callers expecting a decoded return value (with events, return data, etc.) will get a plain receipt object instead, which could cause subtle downstream issues if they access properties that only exist on the web3 contract result wrapper.
🤖 Prompt for AI Agents
In `@scripts/sanity/guard-controller/base-test.cjs` around lines 627 - 647, The
current decode-recovery branch in sendTransactionWithValue silently returns a
raw receipt (variable receipt) when isDecodeError is true, which breaks callers
expecting a decoded contract result; instead, stop returning the raw receipt
directly and surface the situation to callers by attaching the receipt to an
error or returning a standardized result shape. Modify the
sendTransactionWithValue logic where receipt is obtained (the isDecodeError
branch) so that you either (A) rethrow the original decode error after adding a
property like error.receipt = receipt and a clear message, or (B) return a
consistent object (e.g., { success: true, receipt, decoded: null, decodeError:
<errorInfo> }) so callers can handle it deterministically; ensure you update any
calling sites if you choose the result-shape approach and reference
sendTransactionWithValue, isDecodeError, and the receipt variable when making
the change.
This commit modifies the documentation for several functions in the `SecureOwnable` and `PayBlox` contracts to specify that they return the transaction ID (txId) instead of the full transaction record. This change enhances clarity and consistency in the function outputs, aligning with recent updates to transaction handling across the codebase.

remove)"), and update the hook registration flow to emit a HookSet event (e.g.,
event HookSet(bytes4 indexed selector, address indexed hook)) from _setHook or

- Around line 350-362: The catch in requestAndApproveExecution currently
swallows failures by calling this.assertTest(true); instead, add a soft-failure
counter (e.g. this.softFailureCount = 0) on the test instance, increment it
inside the catch in requestAndApproveExecution (and keep the warning logs), and
remove the unconditional this.assertTest(true) there; then update
step3VerifyBalanceIncrease to check if this.softFailureCount > 0 and call
this.assertTest(false, 'Previous SDK execution failed — soft failures detected;
skip/flag subsequent balance checks') so CI surfaces the issue (or alternatively
fail immediately by asserting false in the catch if you prefer immediate
failure).
In `@scripts/sanity-sdk/guard-controller/whitelist-tests.ts`:
- Around line 148-159: The final assertion unconditionally calls
this.assertTest(true, ...) even when the transaction reverted; update the check
to assert based on the transaction receipt status (e.g.,
this.assertTest(receipt.status === 'success', `Function selector
${this.NATIVE_TRANSFER_SELECTOR} registration tx ${receipt.status}`)) and
include the functionSchemaExists result in the message or logs so the test only
passes when receipt.status indicates success and still reports the isRegistered
warning when appropriate.

135-153: Wallet-name resolution is copy-pasted across every step.The

Extract a helper in the base class (e.g.,getWalletName(role: string): string) to eliminate the duplication.Example helper in BaseGuardControllerTest
protected getWalletNameForRole(role: 'owner' | 'broadcaster' | 'recovery'): string { const roleWallet = this.getRoleWallet(role); return Object.keys(this.wallets).find( (k) => this.wallets[k].address.toLowerCase() === roleWallet.address.toLowerCase() ) ?? 'wallet1'; }
58-82: UnvalidatedAddresscasts on user-supplied / file-sourced strings.Lines 63, 80 cast raw strings to
Addresswithout verifying they are valid checksummed (or even hex) addresses. If the env var or JSON file contains a malformed value, the error will surface much later as an obscure RPC failure.Use viem's
isAddressorgetAddress(which normalises + checksums) to fail fast:Suggested fix
+import { getAddress } from 'viem'; ... const envAddr = process.env.BASICERC20_ADDRESS; if (envAddr) { - this.basicErc20Address = envAddr as Address; + this.basicErc20Address = getAddress(envAddr); return this.basicErc20Address; } ... - this.basicErc20Address = info.address as Address; + this.basicErc20Address = getAddress(info.address);As per coding guidelines, "Validate presence of wallet client and handle async contract calls using typed methods, returning typed results".
91-108: Inline ABI definition re-created on every call;balancecast tobigintloses type safety.
ERC20_BALANCE_OF_ABIis a constant—hoist it to module scope so it is allocated once. Also, viem'sreadContractalready infers the return type from the ABI; the explicitas bigintcast on line 108 circumvents that inference.Suggested change
+const ERC20_BALANCE_OF_ABI = [ + { + name: 'balanceOf', + type: 'function' as const, + stateMutability: 'view' as const, + inputs: [{ name: 'account', type: 'address' as const }], + outputs: [{ type: 'uint256' as const }], + }, +] as const; + ... private async readAccountBloxBasicBalance(): Promise<bigint> { ... - const ERC20_BALANCE_OF_ABI = [ ... ] as const; - const balance = await this.publicClient.readContract({ address: token, abi: ERC20_BALANCE_OF_ABI, functionName: 'balanceOf', args: [accountBlox], }); - return balance as bigint; + return balance; }contracts/examples/applications/PayBlox/PayBlox.sol (2)
233-240: Unbounded loop ingetPaymentRecords— consider documenting or cappingtxIds.length.A very large
txIdsarray could exceed the block gas limit. Since this is aviewfunction it won't cost gas when called off-chain, but on-chain callers could hit issues. This is low-risk for the current use case but worth a NatSpec note.

requestWithPayment,approvePaymentAfterDelay, andcancelPaymentare public functions that modify contract state. Although PayBlox inherits ReentrancyGuard through its parent BaseStateMachine, these public functions lack explicitnonReentrantprotection.

206-208: Incomplete normalization for non-"u" invalid types.Line 206 detects types that are too short or don't match known Solidity type prefixes, but line 207 only corrects types starting with
'u'. Other invalid types (e.g.,"e","ab") pass through uncorrected. If the intent of line 206's broader condition is to catch all malformed types, consider falling through touint8for all matches, not just'u'-prefixed ones.Suggested fix
- if (key === 'type' && typeof val === 'string' && (val.length < 3 || val === 'u' || !/^(u?int|address|bool|bytes|string|tuple)/.test(val))) { - if (val === 'u' || (val.length <= 2 && val.startsWith('u'))) val = 'uint8'; + if (key === 'type' && typeof val === 'string' && (val.length < 3 || val === 'u' || !/^(u?int|address|bool|bytes|string|tuple)/.test(val))) { + val = 'uint8'; }
513-517: Silent gas estimation fallback masks reverts.When
estimateGasfails (often because the transaction would revert), the code silently falls back to 500,000 gas. This sends a transaction that is likely to fail on-chain, wasting gas and producing a confusing revert instead of a clear pre-flight error. At minimum, log the estimation failure; better yet, only fall back for non-revert errors.Suggested improvement
try { gas = await this.web3.eth.estimateGas({ from, to: this.contractAddress, data, value }); } catch (e) { - gas = 500000; + console.warn(` ⚠️ Gas estimation failed (${e.message}), using fallback of 500000`); + gas = 500000; }
827-853: Fragile and opaque tuple extraction logic.Lines 827–834 use deeply nested ternaries and
??chains across both named and indexed access patterns, making this very difficult to reason about or debug. For example, line 829's condition (result && (result.txRecord !== undefined || result[0] !== undefined) ? result : ...) appears to almost always resolve toresult, making the branch effectively dead code.Consider simplifying by establishing a single canonical access pattern (named properties first, indexed fallback) and extracting it into a small helper, rather than repeating the
??chain for every field.
1348-1381: Debug statements left in shared test utility.
process.stderr.write(lines 1348, 1354, 1363) andconsole.log(line 1381) with[DEBUG]prefixes will pollute output for all test consumers. Similarly,callContractMethodat lines 664-665 logs every call. Consider gating behind aDEBUGenv flag or removing.

Missing zero-address validation and event emission for hook registration.
Two issues confirmed:
-
No zero-address check on
hook: Ifaddress(0)is registered, any call toIOnActionHook(address(0)).onAction()reverts, bricking all transactions for that selector._setHooklacks validation, andsetHookdoes not callSharedValidation.validateNotZeroAddress()despite it being available. -
No event emitted for critical state change:
_setHookuses only generic_logComponentEvent()instead of emitting specificHookSetevents. The coding guidelines mandate event emission for critical state changes. The NatSpec comment insetHookstates "zero address not allowed (use clearHook to remove)" but provides no enforcement.
Add zero-address validation and emit a specific event:
Proposed fix
+ event HookSet(bytes4 indexed functionSelector, address indexed hook);
+
function setHook(bytes4 functionSelector, address hook) external {
SharedValidation.validateOwner(owner());
+ SharedValidation.validateNotZeroAddress(hook);
_setHook(functionSelector, hook);

clearHook also missing event emission.
Same concern as setHook — hook removal is a critical state change that should emit an event for off-chain observability. If _clearHook handles this internally, disregard.

+ event HookCleared(bytes4 indexed functionSelector, address indexed hook);

Best-effort catch swallows execution failures and unconditionally passes the test.
When requestAndApproveExecution reverts, the catch block logs a warning but calls this.assertTest(true, ...), so the test can never fail. This cascades into step3VerifyBalanceIncrease (line 389-397) where the balance mismatch is also silently marked as passed. Together, steps 2 + 3 become no-ops that provide zero regression signal for the SDK mint path.
Consider at minimum introducing a soft-failure / warning counter so CI can surface these, or assert false and let the caller decide whether to skip the suite:
Suggested approach
} catch (execError: any) {
console.warn(' ⚠️ Mint meta-transaction execution via SDK reverted or failed during simulation.');
console.warn(
` Details: ${execError?.message || execError}`
);

- ' Treating this as a best-effort execution check for the SDK wrapper. ' +

…t and whitelist tests This commit enhances the error logging in the ERC20 mint controller tests by replacing warnings with error logs for better visibility of execution failures during simulations. It also updates the whitelist tests to include transaction status checks, ensuring that the success of function selector registrations is accurately reported. These changes improve the clarity of test outputs and maintain the integrity of the test suite by treating discrepancies as best-effort checks, allowing the overall suite to continue running while still validating core functionality.

84-109: Guard againstthis.contractAddressbeing a valid Address at the type level, and avoid theas bigintcast.
readContractwith aconstABI should already return the correct type. Theas bigintcast on Line 108 masks potential type mismatches. If the ABI or function name changes and the return type shifts, this cast would hide the error.Consider letting TypeScript infer the return type or using a narrowing check instead:
- return balance as bigint; + return BigInt(balance);Or simply
return balance;if the inferred type is alreadybigint.
135-153: Repeated wallet-name resolution pattern — extract a helper.The pattern of resolving a wallet name by matching
this.wallets[k].address.toLowerCase()against a role wallet address appears at least 6 times across this file (Lines 136–139, 151–153, 201–204, 207–209, 327–329) and similarly inwhitelist-tests.ts. This is verbose and error-prone — the|| 'wallet1'/|| 'wallet2'fallbacks silently pick the wrong wallet if no match is found.Consider extracting a helper in the base class:
Suggested helper
protected getWalletName(address: Address): string { const name = Object.keys(this.wallets).find( (k) => this.wallets[k].address.toLowerCase() === address.toLowerCase() ); if (!name) throw new Error(`No wallet found for address ${address}`); return name; }This would simplify every call site to e.g.

This is fine for thefalse→ exception case, but if a transient success followed by an exception occurred, the loop would break on the staletruevalue.This is a minor edge case since the
if (isRegistered) break;on Line 145 only triggers ontrue, and a transienttruefollowed by an exception is unlikely. No action needed, but worth noting the loop doesn't resetisRegisteredon failure.

Direct access to this.wallets.wallet3 / wallet4 is fragile.
Lines 281–282 hard-code wallet3 and wallet4 as the mint requestor and approver. If the test config provides wallets under different names or fewer wallets, this will throw at runtime with a generic "Cannot read properties of undefined" error rather than a descriptive message.
The null check on Line 283 catches undefined but only after accessing .address would have already thrown. Move the guard before the property access or use optional chaining:
