This project is a work in progress, aiming to create an ERC-4337 compliant account abstraction wallet and a factory from which to deploy them. The implementation heavily relies on inline assembly for efficiency and direct control over the EVM.
The wallet contract provides the functionality of a basic Ethereum smart contract wallet but with additional features defined by the ERC-4337 standard. The factory contract is used to deploy new instances of the wallet contract.
The project is inspired by the Solady project and uses many of the library's functions.
Testing is done using the forking feature of Foundry. This allows us to simulate the behavior of the contracts in a realistic environment, including interaction with other contracts(i.e., the EntryPoint contract) on Ethereum mainnet.

The basic structure of the wallet and factory contracts has been implemented, but there is still much work to be done. The next steps include implementing the full ERC-4337 interface in the wallet contract and adding more comprehensive tests.
Contributions and feedback are welcome.
