abi.encode The solidity built-in function abi.encode enables to encode any Solidity types into raw bytes, that can be interpreted directly by the EVM. Note that multiple arguments can be given to this function. Let's start with the first example: string. abi .encode("Solidity") The function above will return the following raw bytes value.
That's how the ABI works. If you have a dynamic type, its actual slot contains the offset pointing to the actual location of the values (including the prepended length). In your case that's 160 (hex a0) bytes. All dynamic values are ordered at the end of the payload, prepended by a length of the section.
