📝 Summary

The purpose of this PR is to introduce a binary that allows for backtesting with synthetic bundles. It builds off of #55 and #54, which need to be merged first.

It does this by adding a csv that contains synthetic bundles, and then loading that with a balance override in the EVM to spoof balances of tx senders.

💡 Motivation and Context

The idea is to provide a useful set of MEV aware synthetic bundles that can allow for open source contributors to work on bundle merging without access to sensitive data.


✅ I have completed the following steps:

  • [✅] Run make lint
  • [✅] Run make test
  • Added tests (if applicable)
