All thirdweb contracts have a read method called contractURI. It returns an IPFS URI (string). You can fetch the data from that location using thirdweb/storage ’s download module. The result should be a JSON object containing the metadata about the contract.

You, however, do not have to go through all the steps above. The metadata can be loaded using the following code snippet:

import { getContractMetadata } from "thirdweb/extensions/common";
const metadata = await getContractMetadata({ contract });

An example of the metadata:

{
	name: "Bored Ape Yatch Club",
	symbol: "APE",
	description: "Not the official BAYC collection"
}

There isn’t a guaranteed format standard for the contract’s metadata as it can be set arbitrarily by users.
