Summary of Changes

Hello @0xh3rman, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces comprehensive support for the Monad blockchain within the Across protocol. It integrates Monad by configuring its specific deployment parameters, such as the spoke pool and multicall addresses, and by registering its primary stablecoin assets, USDC and USDT. This expansion enables the system to facilitate cross-chain operations involving the Monad network.

Highlights

• Monad Chain Integration: Added comprehensive support for the Monad blockchain within the Across protocol, including its specific deployment configurations.
• Asset Support: Integrated USDC and USDT as supported assets for the Monad chain, defining their asset IDs and decimal mappings.
• Swapper Functionality Extension: Updated the swapper provider to recognize and facilitate cross-chain operations involving Monad chain assets, accompanied by new test cases.

Code Review

This pull request adds support for the Monad chain to the Across swapper. The changes are generally correct, introducing the necessary configurations and test cases. My feedback primarily focuses on improving code consistency and readability by sorting items in various lists, match arms, and HashSets. Adopting a consistent sorting order will enhance future maintainability. I've also included suggestions to improve the structure of the test code for better clarity.
