arb-deflate

A simple single-owner smart contract wallet built with Arbitrum Stylus that allows arbitrary call and delegatecalls. It uses flate2's inflate implementation to inflate a deflated(compressed) calldata. This allows for shorter calldata and lower transaction costs since on L2s calldata is more expensive than execution costs.
