Huff-golfing for cheap account abstraction
This repo contains a Huff-rewrite of the ERC-4337 EntryPoint contract. The EntryPoint contract is critical infra for ERC-4337 that routes UserOperations (psuedo-transactions) to the correct account contract, including account deployment, validation and execution.
Note
These contracts are unaudited and are not recommended for use in production.
The main usage of these contracts is to find out how much gas can be saved by using a Huff EntryPoint.
