@lukema95 thanks so much for your contribution! 🙌 One last request before we merge: please, run yarn generate, so Go files are generated from the updated contracts.

@fadeev After running yarn generate, I encountered an error: 'Error: Failed to compile IERC20Permit'. I'm not sure if this is a normal occurrence, as the IERC20Permit contract is an interface contract from the OpenZeppelin library.

@lukema95 created an issue for this: #100

I think it shouldn't prevent merging this PR, since this error exists on main as well.

@andresaiello please, review.

Hey @lukema95 , sorry for the time coming back on this one.
For some context, we started working on new version for the smart contract architecture: #198
As an improvement, it's still beneficial to merge this. So let me know if you want to solve the current conflicts in the PR and we can merge it. Otherwise we can close the issue as the v1 contracts will become deprecated.

It doesn't matter.
