Solidity Equivalents

When transpiling solidity code which uses ABI encoding, cairo functions are generated to mimic this behaviour.

An Ethereum address has a width of 160 bits, while a Starknet address has a width of 251 bits. To support this change in address size, we had to modified the solc compiler. As a result, Warp's flavour of Solidity uses 256 bits for addresses instead of 160.

Starknet contracts, also known as zk-STARK contracts, are a type of smart contract that utilizes zero-knowledge proof technology to provide privacy and security to its users and these contracts are written in cairo language. Unlike traditional smart contracts written in Solidity, the inputs to a Starknet contract are structurally different, making it necessary to understand how to interact with them effectively.
