AA Benchmark

A benchmark for AA (ERC-4337) smart contract accounts.

All accounts use single-ECDSA signatures. We plan on expanding to other signing schemes in the future (multisig, RSA, etc.).

Results (as of Sep 25, 2023)

Disclaimer the numbers are obtained from local simulations. On-chain numbers might differ slightly.

Since these are gas numbers, lower is better.

How to add your implementation

1. Fork this repo.
2. Add your test file to ./test/; create a folder if needed.
3. Inherit src/TestBase.sol and override getSignature(), fillData(), createAccount(), getAccountAddr(), getInitCode().
   • getSignature(): should return appropriate signature based on _op (e.g. should return ECDSA signature).
   • fillData(): should return appropriate data for userOp.callData.
   • createAccount(): should create the wallet. Skip this if your factory only allows for creation through the EntryPoint.
   • getAccountAddr(): should return the counterfactual address for the given _owner.
   • getInitCode(): should return userOp.initCode.
4. Write setUp() function to set the initial test condition. For instance, it might deploy the factory and the implementation contract. NOTICE since we don't want this repo to have too many dependencies, please use vm.etch and use your predicted address & bytecode to deploy the contract instead of importing your whole code. This will also make it easy to test without compiler setup fiasco.
5. Run WRITE_GAS_PROFILE=true forge test -vv this will show you the results of the benchmark and also output the result as a JSON file to results/.
6. Make a PR to this repository.

TODO

• add paymaster benchmark
• allow non-ECDSA benchmark
  • maybe RSA?
• add CI for cheking/getting the gas results
• L2 gas cost calculation
