This repository is archived and no longer maintained. The contracts here have been moved to JoinOrigami/crane, which you may recognize as the old home of this repository. The significant change is that while this repository used hardhat, the new one uses foundry.
As of 21c44db in this repository, the contracts were essentially identical (save import path changes) to the contracts that were checked into the newer version of this repository. To track further development, view that repository.
