 Note that although the `chainId` parameters is necessary for [EIP-712](./eip-712.md) signatures, we omit the parameter from the event as it can be inferred through the transaction data. Similarly, the `verifyingContract` parameter for signature verification is omitted since it MUST be the same as the `emitter` field in the transaction. `emitter` MUST be the token.
 
-A platform can verify the validity of the creator attribution by reconstructing the signature digest with the parameters emitted and recovering the signer from the `signature` parameter. The recovered signer MUST be the `creator` of the token. If `CreatorAttribution` event is present creator attribution MUST be given to the `creator` instead of the account that submitted the transaction.
