Smart Contracts

There are in total three smart contracts as seen in the image below. The owners of an NFT from the TimePiecePassport contract have the ability to transfer it wherever they want. Just like a normal ERC-721 NFT.

The TimePieceEscrow contract is meant to be used during the step of an order via the OpenChrono website.

The TimePiecePayments contract is meant to be used for crypto payments and to set the Royalties of an NFT.
