L2Pool

https://github.com/Into-the-Fathom/fathom-lending-platform-smart-contracts/blob/master/contracts/protocol/pool/L2Pool.sol

The L2Pool contract is a calldata-optimized extension of the Pool contract in the Fathom lending protocol. It allows users to interact with the protocol using a compact calldata representation, reducing transaction costs on rollups. Users can supply, withdraw, borrow, repay, and perform other standard lending operations with optimized calldata.
