CW721

Introduction

The CW721 ADO is a smart contract to allow users to launch their own custom NFT projects. In addition to the standard CW721 messages, we have added some custom logic to further extend the utility and function of the contract.

The CW721 ADO is one of the base ADOs meaning it can interact with a large number of other ADOs such as the marketplace, crowdfund, auction, CW721 timelock and many more.

The contract has implemented a custom TransferAgreement message to allow the buying/selling of tokens between two parties throught the CW721 ADO itself.

Ado_type: cw721
