### Contracts info

The contracts can be currently found here:

- [GovernancePatchUpgrade](https://git.tornado.ws/Theo/proposal-22-governance-and-rewards-patch/src/branch/main/src/v4-patch/GovernancePatchUpgrade.sol)
- [PatchProposal](https://git.tornado.ws/Theo/proposal-22-governance-and-rewards-patch/src/branch/main/src/v4-patch/PatchProposal.sol)

Inlined version of the `RelayerRegistry` and `TornadoStakingRewards` are also used. Check the `diffs` folder to see how much they deviate from the deployed contract implementations.

For testing resistance against metamorphic contracts, we use the contracts provided by: https://github.com/0age/metamorphic.git
