An attempt to implement account-abstraction as described in ERC-4337 for personal interests.
The main purpose of this implementation is to understand and experience firsthand the key mechanisms and main execution processes of ERC-4337. It is missing at least the following parts, compared to the description in the ERC-4337 Specification:
- The implementation of
postOp - The
deadlinemechanism - The
simulationpart of ERC-4337, as it only needs slight modification to the main execution logic to achieve this
However, I believe this is a good material for learning and understanding this proposal.
Keep in mind: this is a baby-implementation with tutorial purpose and it is not ready for practical uses. The codes are not reviewed or benched as well.
- ERC-4337 Specification.
- eth-infinitism's guide reference implementation for ERC-4337.
- OKX's implementation which is complete, highly audited, and useable in practice.
