# EPF Update 13

## Summary

This is a two-week update because I had a break from 2023/01/22 to 2023/01/26.

1. Create a [replace anvil with Geth pr](https://github.com/Vid201/aa-bundler/pull/40)
2. Merged [unwrap check pr](https://github.com/Vid201/aa-bundler/pull/38)
3. Review vid's pr [#39](https://github.com/Vid201/aa-bundler/pull/39), [#41](https://github.com/Vid201/aa-bundler/pull/41)
4. Submit a [dup pr](https://github.com/gakonst/ethers-rs/pull/2088) to ethers-sr

## Geth js tracer

Currently, ethers-rs doesn't support js tracer option. So I add a pr to fix that. But sadly, Vid has a dup pr which does similar things. I asked the ethers-rs team to review the prs and they took Vid's pr model changes and might look at mine for provider changes.
