[Flow EVM] Add support for ABI encoding/decoding of Solidity `bytes` -related types #5365

Open m-Peter opened 4 months ago

m-Peter commented 4 months ago

Right now, Cadence arrays (fixed & variable sized) are ABI encoded/decoded to Solidity array equivalents. That means we cannot map a Cadence [UInt8; 4] type to Solidity bytes4. To overcome this, we can define a new composite type on the EVM contract (just like we do for EVM.EVMAddress) and use it to signify in what bytes type we want to encode a Cadence byte array. We should support at minimum bytes / bytes4 / bytes32 and arrays of these 3.

This is still relevant, though maybe not for the first release of Flow EVM
