Events

Creator Token contracts emit several indexible events that should be indexed by off-chain order books.

Off-chain order books SHOULD index the following events for collections they provide listing services for so that the order book can apply the appropriate transfer validation logic to orders such as obtaining an EOA signature from the recipient and registering it with the transfer validator EOA registry or filtering orders that are unfillable based on security settings.

Token Contract Events are emitted by the collection's smart contract. Transfer Validator Events are emitted by transfer validator contracts. A default transfer validator has been deployed that collections SHOULD use, however creators MAY deploy alternative transfer validators.
