Deployments
Contract Deployments
A full list of deployed contracts can be found in the deployments.json file. This contains deployments for all environments and is difficult to parse through manually. You should only need to reference it for automation or as a source of truth. For convenience, we extracted the important contract addresses and listed them here.
Note that the Test Token is a mintable ERC20. The open mint function has the signature mint(address account, uint256 amount) and can be freely called.
