19-21: Ensure consistent parameter usage across functions

In the claim function, the relayer address parameter is omitted, unlike in the relay and prove functions. If the relayer is required for claiming the originally deposited capital, consider including it as a parameter for consistency and clarity. Alternatively, if the relayer is intended to be identified via msg.sender during implementation, evaluate whether the same approach should be applied to the other functions.


8-21: Enhance parameter descriptions for clarity

The current Natspec comments provide basic descriptions. To improve clarity for developers, consider enhancing the parameter descriptions by specifying data types and expected formats where applicable.

Apply the following changes to the comments:

     /// @notice Relays destination side of bridge transaction by off-chain relayer
-    /// @param request The encoded bridge transaction to relay on destination chain
+    /// @param request The ABI-encoded bridge transaction data to relay on the destination chain
     /// @param relayer The address of the relaying entity which should have control of the origin funds when claimed
     function relay(bytes memory request, address relayer) external payable;

     /// @notice Provides proof on origin side that relayer provided funds on destination side of bridge transaction
-    /// @param request The encoded bridge transaction to prove on origin chain
+    /// @param request The ABI-encoded bridge transaction data that was relayed
     /// @param destTxHash The destination transaction hash proving the bridge transaction was relayed
     /// @param relayer The address of the relaying entity which should have control of the origin funds when claimed
     function prove(bytes memory request, bytes32 destTxHash, address relayer) external;

     /// @notice Completes bridge transaction on origin chain by claiming originally deposited capital. Can only send funds to the relayer address on the proof.
-    /// @param request The encoded bridge transaction to claim on origin chain
+    /// @param request The ABI-encoded bridge transaction data to claim on the origin chain
     function claim(bytes memory request) external;
packages/contracts-rfq/test/FastBridgeV2.Parity.t.sol (1)

6-6: Re-evaluate the need to disable Solhint rules

The directive // solhint-disable func-name-mixedcase, ordering disables the func-name-mixedcase and ordering rules. If possible, consider adhering to the standard naming conventions and function ordering to maintain code consistency and readability, rather than disabling these linting rules.

packages/contracts-rfq/test/FastBridgeV2.t.sol (1)

50-53: Add comments to clarify the purpose of empty virtual functions

The functions configureFastBridge() and mintTokens() are empty but marked as virtual. To improve code readability, consider adding comments explaining that these functions are intended to be overridden in derived test contracts to provide specific configurations or setups necessary for testing.

Apply this diff to add explanatory comments:

 function configureFastBridge() public virtual {}
+    // Override to configure the FastBridge instance with specific settings for tests

 function mintTokens() public virtual {}
+    // Override to mint tokens required for test scenarios
packages/contracts-rfq/test/FastBridgeV2.Management.t.sol (2)

95-102: Consider Edge Cases in Fee Sweeping Tests

In test_sweepProtocolFees_erc20 and test_sweepProtocolFees_eth, the tests assume that there are protocol fees collected. Ensure that cases where no fees are collected are also tested to confirm the functions handle zero balances gracefully.

Consider adding tests for zero protocol fees:

+function test_sweepProtocolFees_zeroFees() public {
+    // Ensure protocol fees are zero
+    assertEq(fastBridge.protocolFees(address(srcToken)), 0);
+    vm.expectRevert("No fees to sweep");
+    sweepProtocolFees(governor, address(srcToken), governorA);
+}

Also applies to: 104-111


53-57: Missing Assertion Message in Role Assignment Test

In test_grantGovernorRole, the assertions lack custom messages. Adding messages can aid in debugging if the test fails.

Enhance assertions with messages:

-assertFalse(fastBridge.hasRole(GOVERNOR_ROLE, governorA));
+assertFalse(fastBridge.hasRole(GOVERNOR_ROLE, governorA), "GovernorA should not have the role before assignment");
packages/contracts-rfq/test/FastBridgeV2.Dst.t.sol (1)

40-53: Parameterize chainGasAmount in expectBridgeRelayed() for flexibility

Currently, chainGasAmount is hardcoded to 0 in the expectBridgeRelayed function. To enhance flexibility and allow testing of scenarios with different chainGasAmount values, consider parameterizing this field.

Apply the following diff to modify the function:

 function expectBridgeRelayed(IFastBridge.BridgeTransaction memory bridgeTx, bytes32 txId, address relayer) public {
     vm.expectEmit(address(fastBridge));
     emit BridgeRelayed({
         transactionId: txId,
         relayer: relayer,
         to: bridgeTx.destRecipient,
         originChainId: bridgeTx.originChainId,
         originToken: bridgeTx.originToken,
         destToken: bridgeTx.destToken,
         originAmount: bridgeTx.originAmount,
         destAmount: bridgeTx.destAmount,
-        chainGasAmount: 0
+        chainGasAmount: bridgeTx.chainGasAmount
     });
 }

Ensure that bridgeTx includes the chainGasAmount field and update any calls to expectBridgeRelayed accordingly.

packages/contracts-rfq/contracts/FastBridgeV2.sol (2)

183-191: Improve Event Logging in prove Function

The BridgeProofProvided event does not emit the destTxHash, which could be valuable for tracking purposes.

Recommendation:

Include destTxHash in the emitted event.

event BridgeProofProvided(
    bytes32 indexed transactionId,
    address indexed relayer,
+   bytes32 destTxHash
);

- emit BridgeProofProvided(transactionId, relayer, destTxHash);
+ emit BridgeProofProvided(transactionId, relayer, destTxHash);

251-260: Clarify Event Parameters in dispute Function

The BridgeProofDisputed event could include additional information to aid in debugging and tracking.

Recommendation:

Include the relayer and reason in the event.

event BridgeProofDisputed(
    bytes32 indexed transactionId,
    address indexed disputer,
+   address indexed relayer
);

emit BridgeProofDisputed(transactionId, msg.sender, bridgeProofs[transactionId].relayer);

226-227: Implement the test_bridge_userSpecificNonce test

The test test_bridge_userSpecificNonce is currently skipped with a TODO comment. Implement this test to verify that user-specific nonces are handled correctly in bridging operations.

Do you want me to help implement this test or open a GitHub issue to track this task?


286-290: Resolve the skipped test in test_bridge_revert_zeroSender

The test test_bridge_revert_zeroSender is skipped with a TODO comment. Address this to ensure the contract correctly handles cases where the sender address is zero.

Do you need assistance in fixing this test or should I open a GitHub issue to track it?


293-297: Address the skipped test in test_bridge_revert_zeroRecipient

The test test_bridge_revert_zeroRecipient is skipped with a TODO comment. Implement this test to confirm that the contract properly reverts when the recipient address is zero.

Would you like me to assist in implementing this test or create a GitHub issue for it?


803-806: Unskip and fix the test_refund_revert_statusNull test

The test test_refund_revert_statusNull is skipped with a TODO comment. Resolve the underlying issue to enable this test and ensure proper refund behavior when the status is NULL.

Can I assist in fixing this test or should we open a GitHub issue to track this task?


809-814: Unskip and fix the test_refund_revert_statusProven test

This test is currently skipped. Implementing it will help verify that refunds properly revert when the status is PROVEN.

Would you like assistance in addressing this test or should a GitHub issue be created?


817-824: Unskip and fix the test_refund_revert_statusClaimed test

The test is skipped pending a fix. Ensure that refunds correctly revert when the status is CLAIMED by resolving this test.

21-21: Verify compatibility with Solidity v0.8.24

The Solidity compiler version has been updated to v0.8.24. Please ensure that all contracts compile successfully with this new version and review the Solidity release notes for any potential breaking changes or deprecations that might affect the codebase.

packages/contracts-rfq/test/FastBridgeV2.Src.ProtocolFees.t.sol (2)

16-24: Ensure transaction amounts align with the 1% protocol fee rate

In createFixtures(), the transaction amounts and fees are set manually. Please verify that these amounts correctly reflect the 1% protocol fee rate configured earlier. Consistency between the fee rate and the fixture amounts is crucial for accurate testing.

For example, for the token transaction:

  • Total amount: tokenTx.originFeeAmount + tokenTx.originAmount = 0.01e6 + 0.99e6 = 1e6
  • Expected fee (1% of total amount): 1e6 * 1% = 0.01e6

Similarly, for the ETH transaction:

  • Total amount: ethTx.originFeeAmount + ethTx.originAmount = 0.01 ether + 0.99 ether = 1 ether
  • Expected fee (1% of total amount): 1 ether * 1% = 0.01 ether

Please confirm that the destAmount values (tokenTx.destAmount, ethTx.destAmount) are consistent with the fee deductions as per the protocol logic.


10-11: Verify that setProtocolFeeRate(1e4) correctly sets the fee rate to 1%

The call to fastBridge.setProtocolFeeRate(1e4); aims to set the protocol fee rate to 1%, as indicated by the comment // 1%. Please verify that 1e4 corresponds to a 1% fee rate in the fastBridge contract's context. This ensures that fee calculations in the tests align with the intended rate.

To confirm how the fee rate is interpreted, run the following script to examine the setProtocolFeeRate function and its usage in fee calculations:

Verification successful

Verification confirms setProtocolFeeRate(1e4) correctly sets the fee rate to 1%

The codebase analysis verifies that setProtocolFeeRate(1e4) indeed sets the protocol fee rate to 1% as intended. Here's a brief explanation:

  • The fee calculations use the formula: (amount * protocolFeeRate) / FEE_BPS or (amount * protocolFeeRate) / 1e6.
  • FEE_BPS is equivalent to 1e6 (1 million), representing 100% in basis points.
  • Setting protocolFeeRate to 1e4 (10,000) results in a 1% fee rate: 10,000 / 1,000,000 = 0.01 = 1%.

The test in FastBridgeV2.Src.ProtocolFees.t.sol correctly sets the fee rate to 1% using setProtocolFeeRate(1e4).

110-112: Ensure consistent hashing by verifying struct encoding

In the getTxId function, the bridge transaction is hashed using abi.encode(bridgeTx). To ensure consistent and reliable hashing, verify that all fields within IFastBridge.BridgeTransaction are of statically-sized types. If any fields are dynamically-sized (such as bytes or string), the hashing may produce inconsistent results across different executions. If necessary, consider encoding each field explicitly or ensuring that only statically-sized types are used.

83-84: Incorrect Revert Message Expectation

In test_setProtocolFeeRate_revert_tooHigh, you're expecting the revert message "newFeeRate > max". Ensure that the actual revert message from the setProtocolFeeRate function matches this string exactly. Any mismatch will cause the test to fail unexpectedly.

Run this script to confirm the revert message in the FastBridgeV2 contract:

Verification successful

Revert Message Expectation is Correct

The review comment's concern about the revert message expectation is unnecessary. The expected message "newFeeRate > max" in the test file matches exactly with the actual implementation in the Admin.sol contract, which is likely the base contract for FastBridgeV2.

  • The setProtocolFeeRate function in packages/contracts-rfq/contracts/Admin.sol uses the exact revert message: "newFeeRate > max".
  • This message is consistently used across multiple contract versions and test contracts.

The test test_setProtocolFeeRate_revert_tooHigh is correctly expecting the revert message, and no changes are needed.

Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify the revert message in `setProtocolFeeRate`.

39-40: Ensure Proper Access Control Testing

The functions setProtocolFeeRate and test_setProtocolFeeRate_revert_notGovernor rely on access control. Verify that the fastBridge.GOVERNOR_ROLE() call correctly references the governor role. Additionally, confirm that unauthorized callers are properly restricted in both the implementation and tests.

Run this script to check the access control implementation:

Also applies to: 88-89

Verification successful

Access Control for setProtocolFeeRate and GOVERNOR_ROLE Verified

The verification process confirms that proper access control is implemented for the setProtocolFeeRate function and the GOVERNOR_ROLE:

  • The GOVERNOR_ROLE constant is correctly defined and consistently used across the codebase.
  • The setProtocolFeeRate function in Admin.sol uses the onlyRole(GOVERNOR_ROLE) modifier, ensuring only governors can call it.
  • The test_setProtocolFeeRate_revert_notGovernor function in FastBridgeV2.Management.t.sol properly tests for unauthorized access.

These implementations ensure that only authorized callers (governors) can modify the protocol fee rate, while unauthorized callers are correctly restricted.

The following scripts were executed for the analysis:

Script:

#!/bin/bash

18-20: Ensure Proper Initialization of FastBridgeV2

When deploying FastBridgeV2, confirm that the constructor parameters and initial state are correctly set, especially the admin address. Any misconfiguration could lead to governance issues.

Run this script to verify the constructor of FastBridgeV2:

Verification successful

Proper Initialization of FastBridgeV2 Confirmed

The constructor of FastBridgeV2 correctly passes the _admin address to its parent Admin contract, which likely sets up the initial admin role. All state variables are appropriately initialized or don't require explicit initialization. The simplicity of the constructor aligns with best practices for contract deployment.

For completeness, please manually verify the role setup in the Admin contract to ensure all necessary roles are properly assigned during initialization.

packages/contracts-rfq/test/FastBridgeV2.Dst.t.sol (10)

24-27: Initialization in setUp() is correctly implemented

The setUp function properly sets the chain ID to DST_CHAIN_ID and initializes the test environment by calling super.setUp(). This ensures that the destination chain context is accurately simulated for the tests.


29-31: Correct deployment of FastBridgeV2 contract

The deployFastBridge function deploys a new instance of the FastBridgeV2 contract using address(this) as the constructor argument. This is appropriate since the contract may require a reference to the deploying contract for testing purposes.


33-38: Proper token minting and approvals in mintTokens()

The mintTokens function correctly mints the necessary token balances for relayerA and sets up ETH for relayerB. The use of vm.prank(relayerA) ensures that the approve call is made from the relayerA address, allowing the fastBridge contract to spend the tokens on behalf of relayerA.


74-83: test_relay_token() accurately tests ERC20 token relay functionality

The test_relay_token function effectively verifies that an ERC20 token bridge request is correctly processed by relayerA. It checks the event emission, updates to the bridgeRelays mapping, and the token balances of userB, relayerA, and the fastBridge contract.


85-94: test_relay_token_withRelayerAddress() validates relaying with a specified relayer address

This test ensures that relayerA can relay a transaction while specifying relayerB as the relayer address. It confirms that the BridgeRelayed event reflects the correct relayer and that token balances are updated appropriately.


96-105: test_relay_eth() correctly tests ETH bridge relay

The test function successfully validates that relayerB can relay an ETH bridge request. It checks for correct event emission, updates to the bridgeRelays mapping, and verifies the ETH balances of userB, relayerB, and the fastBridge contract.


107-116: test_relay_eth_withRelayerAddress() tests relaying ETH with a specified relayer address

This test confirms that relayerB can relay an ETH transaction while specifying relayerA as the relayer. It ensures the event logs and balance changes reflect the intended behavior.


120-124: test_relay_revert_chainIncorrect() correctly checks for chain ID mismatches

The test effectively verifies that attempting to relay a transaction on the wrong chain (SRC_CHAIN_ID instead of DST_CHAIN_ID) results in a revert with the ChainIncorrect error, ensuring the contract's chain validation logic is functioning.


126-130: test_relay_revert_transactionRelayed() ensures duplicate transactions are prevented

This test appropriately checks that attempting to relay the same transaction twice results in a revert with the TransactionRelayed error, preventing duplicate processing of bridge transactions.


132-136: test_relay_revert_deadlineExceeded() validates deadline enforcement

The test confirms that if a relay attempt is made after the DEADLINE has passed, the contract correctly reverts with the DeadlineExceeded error, enforcing the timing constraints of the relay process.

244-245: Ensure Safe Token Transfers

Using universalTransfer may not handle all ERC20 tokens safely, especially those that do not return a boolean.

Recommendation:

Confirm that universalTransfer correctly handles tokens that do not adhere to the ERC20 standard fully. Consider using SafeERC20.safeTransfer for improved safety.


82-83: Validate Token Addresses Against Known Standards

The checks for zero addresses in originToken and destToken could be extended to validate that the tokens conform to ERC20 standards.

Recommendation:

Implement additional validation to ensure tokens comply with expected interfaces.

742-752: Verify the refund recipient in test_refund_eth_diffSender

In this test, the refund is sent to userA, even though userB initiated the bridge. Confirm that ethParams.sender is correctly set to userA and that this behavior is intended.

Please double-check that ethParams.sender is set to userA as expected, and that the refund logic aligns with the intended functionality.

31-33: Enhancing test setup extensibility by making 'setUp' virtual

The setUp() method is now marked as virtual, allowing derived test contracts to override it. This increases test flexibility and modularity. Initializing fastBridge using the deployFastBridge() method enhances customization.


39-41: Introducing 'deployFastBridge' method for customizable deployment

The new deployFastBridge() method is marked as internal virtual, enabling derived contracts to override and customize the deployment logic of the FastBridge. This improves modularity and supports different deployment scenarios in tests.


43-43: Making '_mintTokensToActors' virtual for flexible token distribution

By marking _mintTokensToActors() as virtual, you allow derived test contracts to override the token minting process. This enhances flexibility for testing with different token distributions or amounts.


1304-1304: Allowing 'test_failedRelayNotRelayer' to be overridden in derived tests

Marking test_failedRelayNotRelayer() as virtual enables derived test contracts to customize or extend the test behavior. This provides greater flexibility in testing different failure scenarios related to relayers.


1649-1649: Enabling override of 'test_failedClaimNotOldRelayer' for extended testing

By making test_failedClaimNotOldRelayer() virtual, you allow derived test contracts to override this function. This facilitates more comprehensive testing of claim failures involving relayer roles.


1686-1686: Making 'test_failedClaimNotRelayer' virtual for customizable test behavior

Marking test_failedClaimNotRelayer() as virtual provides the ability for derived test contracts to override and tailor the test logic. This enhances the extensibility of tests related to relayer authorization.

Validate the necessity of the relayer parameter in relay function

The relay function includes a relayer address parameter. Since interfaces cannot implement logic, it's important to ensure that the implementation will correctly handle this parameter. Consider whether the relayer address should be obtained from msg.sender within the implementation to prevent potential misuse where a caller could specify a different relayer address, which might introduce security risks.

Assess the use of the relayer parameter in prove function

Similar to the relay function, the prove function takes a relayer address as a parameter. Verify whether it's necessary to pass the relayer explicitly, or if it should be derived from msg.sender during implementation. This could prevent scenarios where a malicious actor proves a transaction on behalf of another relayer without authorization.

Add events for important state-changing functions

Interfaces often include event declarations for significant actions to enhance transparency and enable off-chain monitoring. Consider adding events for the relay, prove, and claim functions to allow tracking when these actions occur in the implementing contracts.

Apply the following changes to declare events:

 interface IFastBridgeV2 is IFastBridge {

packages/contracts-rfq/test/FastBridgeV2.Src.ProtocolFees.t.sol (1)

6-6: Consider Removing Unnecessary Solhint Rule Suppression

The comment // solhint-disable func-name-mixedcase, ordering disables linting rules that help maintain code consistency and style conventions. If the functions in this contract adhere to standard naming and ordering practices, consider removing this suppression to enforce linting and improve code quality.

packages/contracts-rfq/test/FastBridgeV2.Parity.t.sol (3)

15-18: Consider removing or updating the skipped test

Since the relay function is no longer permissioned, the test test_failedRelayNotRelayer is no longer applicable. Consider removing this test or updating it to reflect the new behavior to keep the test suite clean and maintainable.


20-24: Consider removing or updating the skipped test

The test_failedClaimNotRelayer is skipped because the claim function is no longer permissioned by role. To maintain a clean test suite, consider removing this test or updating it to test relevant scenarios under the new permissioning logic.


29-29: Review the necessity of setUpRoles() in the updated test

Since the claim function is no longer permissioned by roles, the call to setUpRoles(); may be unnecessary. Consider removing it if it's no longer needed to streamline the test and avoid confusion.

packages/contracts-rfq/test/FastBridgeV2.t.sol (1)

14-121: Add concrete test functions to FastBridgeV2Test

The FastBridgeV2Test contract currently lacks concrete test cases. While it sets up the testing environment, adding test functions (prefixed with test) is essential to validate the FastBridgeV2 contract's functionality. This will improve test coverage and ensure that all features work as intended.

Would you like assistance in creating initial test cases to validate core functionalities such as bridging tokens, handling ETH transfers, and enforcing access controls?

21-21: Ensure Solidity codebase compatibility with compiler version 0.8.24

Upgrading the compiler to Solidity v0.8.24 is beneficial, but please verify that all Solidity files in the codebase are compatible with this version. Specifically, check that the pragma statements do not restrict the compiler version below 0.8.24.

Run the following script to identify any Solidity files with pragma statements that may not be compatible:

Verification successful

Compiler upgrade to v0.8.24 is compatible with the codebase

The change to use Solidity compiler version 0.8.24 in .vscode/settings.json is safe and compatible with the existing codebase. No files explicitly restrict the compiler version to below 0.8.24, allowing for this upgrade.

However, please note:

  • Many files use lower versions (e.g., 0.8.17, 0.8.20) but don't have upper bounds preventing 0.8.24 usage.
  • Some files use older versions (0.6.x, 0.7.x). While they don't conflict with the 0.8.24 setting, they may need careful review for compatibility in the future.

Recommendation: Proceed with the compiler upgrade, but consider gradually updating older files to newer Solidity versions in future maintenance tasks.

packages/contracts-rfq/test/FastBridgeV2.Src.ProtocolFees.t.sol (2)

8-12: FastBridge Configuration is Correctly Set Up [Approved]

The configureFastBridge function appropriately calls the parent implementation and correctly sets up the testing environment by:

  • Granting the GOVERNOR_ROLE to the contract itself, which is necessary for governance actions within the test.
  • Setting the protocol fee rate to 1e4, which represents 1% if the fee rate is measured in parts per million (PPM). This is appropriate for testing the protocol fee functionality.

14-24: Fixture Creation Correctly Initializes Test Parameters [Approved]

The createFixtures function successfully initializes the transaction parameters for both token and ETH transactions. The values assigned are:

  • Origin fee amounts (0.01e6 for tokens and 0.01 ether for ETH), representing 1% fees.
  • Origin amounts (0.99e6 for tokens and 0.99 ether for ETH), which, combined with the fee amounts, total the full transaction amounts.
  • Destination amounts (0.98e6 for tokens and 0.98 ether for ETH), reflecting the deduction of fees.

This setup is logical and ensures comprehensive testing of the protocol's fee handling and transaction processing under defined conditions.

10-13: Deployment of FastBridgeV2 contract is correctly handled

The deployFastBridge() function correctly deploys the FastBridgeV2 contract using the cheatcode, ensuring compatibility between Solidity versions during testing.

packages/contracts-rfq/test/FastBridgeV2.t.sol (2)

114-116: Validate the correctness of expectUnauthorized revert expectation

The expectUnauthorized function anticipates a revert with the AccessControlUnauthorizedAccount selector. Ensure that this selector matches the actual revert reason emitted by the AccessControl contract when unauthorized access is attempted. This guarantees that the test accurately captures unauthorized access scenarios.

Run the following script to verify the revert reason:

Verification successful

Verification successful: expectUnauthorized correctly anticipates AccessControlUnauthorizedAccount revert

The expectUnauthorized function correctly anticipates the AccessControlUnauthorizedAccount revert. This revert is consistently implemented across the AccessControl contracts in the codebase, matching the selector used in the test function.

Key findings:

  • The exact revert statement revert AccessControlUnauthorizedAccount(account, role); is present in the AccessControl implementations.
  • The test correctly imports IAccessControl from OpenZeppelin: import {IAccessControl} from "@openzeppelin/contracts/access/IAccessControl.sol";
  • The selector usage IAccessControl.AccessControlUnauthorizedAccount.selector in the test matches the actual implementation.

This verification confirms that the test accurately captures unauthorized access scenarios as intended.

Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Confirm that AccessControl emits AccessControlUnauthorizedAccount on unauthorized access.

# Test: Search for the revert statement in AccessControl contract. Expect: Matches the selector used.
rg --type solidity 'revert.+AccessControlUnauthorizedAccount' --ignore-case

110-112: Ensure consistent hashing in getTxId for transaction identification

The getTxId function uses keccak256(abi.encode(bridgeTx)) to compute the transaction ID. If any of the fields in BridgeTransaction are of dynamic types (like bytes or string), the hashing might produce inconsistent results due to how dynamic types are encoded. Verify that all fields in BridgeTransaction are of fixed-size types to ensure consistent and collision-resistant hashing.

To confirm the types within BridgeTransaction, run the following script:

packages/contracts-rfq/contracts/FastBridgeV2.sol (3)

52-70: Ensure Safe Handling of Token Transfers in _pullToken Function

The _pullToken function handles token transfers and includes logic to account for tokens with transfer fees or deflationary tokens. Ensure that the calculation of amountPulled accurately reflects the actual tokens received, especially after the safeTransferFrom call.

Please verify that the balance difference calculation correctly accounts for tokens with transfer fees:

amountPulled = IERC20(token).balanceOf(recipient) - amountPulled;

This ensures the contract is aware of the exact amount received.


226-233: Reassess Access Control Logic in claim Function

The claim function allows any caller to claim funds if to is the zero address or if msg.sender matches the proof.relayer. This might unintentionally permit unauthorized users to claim funds.

Please verify that the access control meets the intended design and that only authorized entities can claim the funds. Consider restricting the function to only allow the relayer to call it or adding additional checks.


183-190: Ensure Role Management for Relayers in prove Function

The prove function uses onlyRole(RELAYER_ROLE) to restrict access. Ensure that the role management for RELAYER_ROLE is properly set up and that only trusted relayers are assigned this role.

Please confirm that roles are correctly assigned and managed, possibly by providing documentation or comments on how roles are handled in the Admin contract.

packages/contracts-rfq/test/FastBridgeV2.Src.t.sol (1)

401-411: Verify the handling of address(0) in claim functions

In test_claim_token_permissionless_toZeroAddress (lines 401-411) and test_claim_eth_permissionless_toZeroAddress (lines 468-479), the to parameter in the claim function is passed as address(0). However, the expectBridgeDepositClaimed function expects the to address to be relayerA. Ensure that passing address(0) behaves as intended and that the to address defaults to relayerA or is handled appropriately.

Run the following script to find all instances where claim is called with to as address(0) and verify the behavior:

Also applies to: 468-479

Verification successful

Handling of address(0) in claim functions is correctly tested

The test cases test_claim_token_permissionless_toZeroAddress and test_claim_eth_permissionless_toZeroAddress are correctly designed to verify the handling of address(0) in the claim function. The apparent discrepancy between the expectBridgeDepositClaimed and claim function parameters is intentional and part of the test design.

The tests suggest that the claim function likely has internal logic to handle cases where to is address(0), defaulting to the relayer's address. This is evidenced by:

  1. expectBridgeDepositClaimed is called with to: relayerA
  2. claim is then called with to: address(0)
  3. Subsequent assertions check for successful claim and correct balance updates

To fully verify this behavior:

  • Review the implementation of the claim function to confirm the handling of address(0) cases.
  • Ensure that the FastBridgeV2 contract documentation clearly explains this behavior.

Possible Misalignment of FEE_RATE_MAX Value and Comment

The FEE_RATE_MAX is set to 1e4, which equals 10000. The comment indicates this represents 1%. Typically, a value of 10000 represents 100% when using basis points. If the intended maximum fee rate is 1%, consider adjusting the value to 100.

Apply this diff to correct the value or the comment:

Review the necessity of passing relayer as a parameter

Passing the relayer address explicitly in the relay function may introduce security risks. Since any caller could specify an arbitrary relayer address, consider using msg.sender as the relayer to ensure that the entity initiating the relay is correctly associated.

Validate the relayer parameter in prove function

Similar to the relay function, passing relayer as a parameter in prove could allow malicious actors to misrepresent the relayer's identity. Ensure that the implementation validates the authenticity of the relayer address or considers using msg.sender instead.

Enhance function documentation for clarity

The function comments can be improved to provide clearer guidance:

  • Specify the expected behavior and any assumptions.
  • Clarify the roles and responsibilities of the caller and the relayer.
  • Highlight any security considerations or requirements.

Consider revising the documentation as follows:

For relay:

 /// @notice Relays the destination side of a bridge transaction by an off-chain relayer.
 /// @param request The encoded bridge transaction to relay on the destination chain.
-/// @param relayer The address of the relaying entity which should have control of the origin funds when claimed.
+/// @param relayer The address of the relayer. This address should control the origin funds when claimed to ensure secure transactions.

Apply similar enhancements to the prove and claim function comments.
