Module Byte-Serialization

Byte Serializing Solidity Arguments Schema

Arb-ts includes methods for serializing parameters for a solidity method into a single byte array to minimize calldata. It uses the following schema:

address[]:
field size (bytes) Description
length 1 Size of array
is-registered 1 1 = all registered, 0 = not all registered
addresses 4 or 20 (x length) If is registered, left-padded 4-byte integers; otherwise, eth addresses

non-address[]:
field size (bytes) Description
length 1 Size of array
items (variable) All items (concatenated)

address:
field size (bytes) Description
is-registered 1 1 = registered, 0 = not registered
address 4 or 20 If registered, left-padded 4-byte integer; otherwise, eth address
