578-591: LGTM: New callback function for RaExchangeV3The new
ramsesV2SwapCallbackfunction is correctly implemented and follows the established pattern for swap callbacks in this contract. It properly delegates to theuniswapV3SwapCallbackfunction, maintaining consistency with other DEX integrations.For improved consistency with other callback functions in the contract, consider adding a comment explaining that this function is called by RaExchangeV3 after executing a swap.
You could add a comment similar to the ones used for other callback functions:
+ /// @notice Called to `msg.sender` after executing a swap via RaExchangeV3#swap. function ramsesV2SwapCallback( int256 amount0Delta, int256 amount1Delta, bytes calldata data ) external { uniswapV3SwapCallback(amount0Delta, amount1Delta, data); }

25-25: Version update to 1.1.0The contract version has been updated from 1.0.0 to 1.1.0, which is appropriate given the addition of a new feature (the
ramsesV2SwapCallbackfunction).
Line range hint
1-592: Summary: Addition of RaExchangeV3 supportThe changes in this pull request are minimal and focused:
- The contract version has been updated from 1.0.0 to 1.1.0.
- A new
ramsesV2SwapCallbackfunction has been added to support RaExchangeV3 swaps.These changes expand the contract's capabilities to handle swaps from RaExchangeV3 pools, following the existing patterns in the contract. The implementation appears to be consistent with the current codebase, minimizing the risk of introducing bugs.
No security issues or major concerns were identified during the review. However, it's important to ensure that the integration with RaExchangeV3 is properly tested and that the
uniswapV3SwapCallbackfunction can correctly handle data from RaExchangeV3 pools.To ensure the changes don't introduce any unintended side effects, please run comprehensive tests focusing on:
- The new
ramsesV2SwapCallbackfunction- Integration with RaExchangeV3 pools
- Existing functionality to confirm it remains unaffected
Additionally, consider updating the contract's documentation to reflect the added support for RaExchangeV3.
578-591: Verify RaExchangeV3 integration and compatibilityWhile the implementation of
ramsesV2SwapCallbackfollows the established pattern in the contract, it's crucial to ensure that:
- The contract can properly handle calls from RaExchangeV3 pools.
- The
uniswapV3SwapCallbackfunction can correctly process the data from RaExchangeV3 pools.To verify the integration, please run the following checks:
Please review the results to ensure that RaExchangeV3 is properly integrated and that the
uniswapV3SwapCallbackfunction can handle the data from RaExchangeV3 pools correctly.

578-591: Approve newramsesV2SwapCallbackfunction with a minor suggestionThe implementation of
ramsesV2SwapCallbacklooks correct and consistent with other similar callback functions in the contract. It properly delegates the logic to the existinguniswapV3SwapCallbackfunction, which helps maintain code consistency and reduces duplication.For improved consistency with other callback functions in this contract, consider adding a comment explaining the purpose of this callback, similar to the comments for
uniswapV3SwapCallbackandpancakeV3SwapCallback.
25-25: Summary of changes and considerationsThe changes in this PR are minimal and focused:
- Updated contract version to 1.1.0
- Added
ramsesV2SwapCallbackfunction to support RaExchangeV3 swapsThe implementation follows established patterns in the contract and doesn't introduce significant new risks. However, please consider the following points:
- Ensure that the integration with RaExchangeV3 is thoroughly tested, especially the interaction between
ramsesV2SwapCallbackanduniswapV3SwapCallback.- Verify that the
lastCalledPoolmechanism correctly handles RaExchangeV3 pool addresses to maintain security.- Update the contract's documentation to reflect the added support for RaExchangeV3.
- Consider adding test cases specifically for the new RaExchangeV3 integration.

578-591: Verifymsg.sendercheck for new callback functionWhile the implementation looks correct, it's crucial to ensure that the
msg.sendercheck inuniswapV3SwapCallbackis sufficient for this new use case with RaExchangeV3. Please verify that thelastCalledPoolmechanism correctly handles the RaExchangeV3 pool addresses to prevent unauthorized calls.To assist with this verification, you can run the following script:
✅ Verification successful
msg.sendercheck inuniswapV3SwapCallbackis sufficientThe
uniswapV3SwapCallbackfunction correctly verifies thatmsg.senderis equal tolastCalledPool, ensuring that only authorized pool addresses can invoke the callback. No security issues detected.🏁 Scripts executed

23087-23096: Verify changes from the previous version.The "SALT" and "VERIFIED" fields are consistent with the visible part of the previous version. However, please manually verify the following:
- The address has changed, as expected for a new deployment.
- The OPTIMIZER_RUNS value is appropriate and hasn't changed unexpectedly.
- The CONSTRUCTOR_ARGS are correct for the new version.
These checks will ensure that the deployment configuration is appropriate for version 1.1.0.
