useUpdateMetadata

Hook for updating the metadata of a smart contract.

Available to use on smart contracts that implement the ContractMetadata interface.

The wallet initiating this transaction must have the required permissions to update the metadata, (admin permissions required by default).

Provide your contract instance from the useContract hook as the first argument, and an object fitting the contract-level metadata standards of the new metadata as the second argument, including:

• name : A string for the name of the smart contract (required).

• description : A string to describe the smart contract (optional).

• image : A string or File object containing the URL or file data of an image to associate with the contract (optional).

• external_link : A string containing a URL to view the smart contract on your website (optional).
