Implementing Frontend III - Interacting with NFT Collection

Minting NFTs and Displaying Wallet Assets Using Thirdweb

In this video, we continue our smart contract interactions using Thirdweb, diving into NFT minting and wallet asset display. This builds upon our previous setup and adds more dynamic, user-centered functionality.

1. Introduction to Thirdweb’s Minting Tools

Thirdweb simplifies interacting with smart contracts, including minting NFTs and retrieving owned assets. Key tools we'll use:

• useMintNFT – for minting NFTs
• useOwnedNFTs – to fetch NFTs associated with a user’s wallet

These hooks provide an easy-to-use interface for tasks that would otherwise require complex smart contract interaction.

2. Setting Up the Minting Form

The minting form includes input fields for:

• Name
• Description
• Image URL

Each field is tied to a React useState variable. When the user submits the form, we run handleSubmit.

Validation

Inside handleSubmit, we first check if any of the fields are empty. If so, we return early to avoid submitting invalid data.

3. Creating and Submitting NFT Metadata

After validation, we create the metadata object required for minting. It includes:

• name
• description
• image

We also need the user's wallet address for the to field. To retrieve this, we use the useAddress hook from Thirdweb:

const address = useAddress();

We then call the mintNFT function, passing:

{
  metadata: { name, description, image },
  to: address,
}

The function handles the blockchain interaction, and the UI responds to:

• Loading state – displays a "Minting in progress" message
• Error state – displays a "Minting error" if something goes wrong

4. Creating a Wallet Page to Display NFTs

To let users view their owned NFTs, we build a wallet page using the useOwnedNFTs hook. This hook returns all NFTs owned by a given address.

Steps include:

• Check if the user is connected (i.e., an address exists)
• Display a loading message while NFTs are being fetched
• Map over the returned NFTs and render them using a custom NFTCard component

Example handling:

if (!address) return <p>No wallet detected</p>;
if (isLoading) return <p>Loading NFT data...</p>;

ownedNFTs?.map(nft => (
  <NFTCard key={nft.metadata.id} nft={nft} />
));

This results in a responsive wallet interface that updates in real time based on the connected address.

5. Summary and Next Steps

In this video, we successfully:

• Built a form to mint NFTs with metadata
• Used Thirdweb hooks to handle wallet interaction
• Created a wallet view page displaying user-owned NFTs
