thirdweb SDK

Install thirdweb

Thirdweb is a CLI tool that you need to install to create and manage your Web3 applications.

npx thirdweb install

Create Application

thirdweb offers SDKs for various programming languages, such as React, React Native, TypeScript, Python, Go, and Unity.

In your CLI run the following command:
```
npx thirdweb create --app
```
Input your preferences for the command line prompts:
1. Give your project a name
2. Choose your network: We will choose EVM for Moonbeam
3. Choose your preferred framework: Next.js, CRA, Vite, React Native, Node.js, or Express
4. Choose your preferred language: JavaScript or TypeScript
5. We are choosing Vite and TypeScript for this particular example.
Use the React or TypeScript SDK to interact with your application’s functions. See the section on “interact with your contract”

Get a Thirdweb Client ID

Open the Thirdweb Dashboard and click Add New in the Projects section.
Select Project from the dropdown menu.
Enter a project name and add localhost:5173 under Allowed Domains. Click Create.
A Client ID and Secret ID will be generated. Copy both to a secure location—we’ll only need the Client ID.

Create an .env file

Create an .env file on your root folder.
Add the following:

VITE_TEMPLATE_CLIENT_ID=YOUR_THIRDWEB_CLIENT_ID
VITE_TEMPLATE_CONTRACT_ID=YOUR_CONTRACT_ID

Interact With a Contract

Initialize SDK On Celo

Wrap your application in the ThirdwebProvider component and change the activeChain to Celo

import React from "react";
import { createRoot } from "react-dom/client";
import { App } from "./App";
import { ThirdwebProvider } from "thirdweb/react";

createRoot(document.getElementById("root")!).render(
  <React.StrictMode>
    <ThirdwebProvider>
      <App />
    </ThirdwebProvider>
  </React.StrictMode>
);

Get Contract

To connect to your contract, use the SDK’s getContract method.

import { client } from "./client";
import { getContract, createThirdwebClient } from 'thirdweb';
import { celo } from "thirdweb/chains";

export function App() {
  
  const contract = getContract({
    client,
    address: import.meta.env.VITE_CONTRACT_ADDRESS,
    chain: celo,
  });
	
  return (
	<div>
	  <h2>{contract.contract}</h2>
	</div>
  );
}

Calling Contract Functions

For extension-based functions, use the built-in supported hooks. The following is an example using the NFTs extension to access a list of NFTs owned by an address- useOwnedNFTs

import React, { useState } from 'react';
import { client } from "./client";
import { getContract, createThirdwebClient } from 'thirdweb';
import { celo } from "thirdweb/chains";
import { getOwnedNFTs } from "thirdweb/extensions/erc721";

export function App() {
  const [nftData, setNftData] = useState(null);

  const contract = getContract({
    client,
    address: import.meta.env.VITE_CONTRACT_ADDRESS,
    chain: celo,
  });

  const loadNFTs = async (contractId) => {
    try {
      const nft = await getOwnedNFTs({
        contract,
        start: 0,
        count: 10,
        address: contractId,
      });
      setNftData(nft);
    } catch (error) {
      console.error('Error loading NFT:', error);
    }
  };
	
  React.useEffect(() => {
    loadNFTs(import.meta.env.VITE_CONTRACT_ADDRESS);
  }, []);  	
	
    return (
     <div>
  	  <h2>{nftData[0].metadata.name}</h2>
     </div>
    );
}

Use the useReadContract hook to call any read functions on your contract by passing in the name of the function you want to use.

import React, { useState } from 'react';
import { client } from "./client";
import { getContract, createThirdwebClient } from 'thirdweb';
import { celo } from "thirdweb/chains";
import { getOwnedNFTs } from "thirdweb/extensions/erc721";
import { useReadContract } from "thirdweb/react";

export function App() {
  const [nftData, setNftData] = useState(null);

  const contract = getContract({
    client,
    address: import.meta.env.VITE_CONTRACT_ADDRESS,
    chain: celo,
  });

const { data, isPending } = useReadContract({
  contract,
  method: "function name() view returns (string)",
  params: [],
}); 
  	  	
return (
  <div>
     <h2>{data}</h2>
   </div>
);
}

Use the updatemetadata function to update the metadata on your contract by passing in the information you want to update.

import React, { useState } from 'react';
import { getContract, createThirdwebClient } from 'thirdweb';
import { celo } from "thirdweb/chains";
import { updateMetadata } from "thirdweb/extensions/erc721";

export function App() {
  const [newName, setNewName] = useState('');
  const [isUpdating, setIsUpdating] = useState(false);

  const client = createThirdwebClient({ 
    clientId: import.meta.env.VITE_TEMPLATE_CLIENT_ID
  });

  const contract = getContract({
    client,
    address: import.meta.env.VITE_CONTRACT_ADDRESS,
    chain: celo,
  });

  const updateContractName = async () => {
    if (!newName) {
      alert("Please enter a new name");
      return;
    }

    setIsUpdating(true);

    try {
      console.log("Updating contract metadata name to:", newName);

      const transaction = await updateMetadata({
        contract,
        metadata: {
          name: newName,
        },
      });

      console.log("Transaction sent:", transaction);
      console.log("Contract metadata updated successfully!");

      alert("Contract metadata updated successfully!");
    } catch (error) {
      console.error('Error updating contract metadata:', error);
      alert("Failed to update contract metadata. Check the console for details.");
    } finally {
      setIsUpdating(false);
    }
  };

  return (
    <div>
      <h2>Update Contract Metadata Name</h2>
      <input
        type="text"
        placeholder="Enter new name"
        value={newName}
        onChange={(e) => setNewName(e.target.value)}
      />
      <button onClick={updateContractName} disabled={isUpdating}>
        {isUpdating ? "Updating..." : "Update Name"}
      </button>
    </div>
);

Connect Wallet

Create a custom connect wallet experience by declaring supported wallets passed to your provider.

import React, { useState } from 'react';
import { client } from "./client";
import { ConnectButton } from "thirdweb/react";
import { createWallet, inAppWallet } from "thirdweb/wallets";

const wallets = [
  inAppWallet(),
  createWallet("io.metamask"),
  createWallet("com.coinbase.wallet"),
  createWallet("me.rainbow"),
];

export function App() {
 
  return (
    <div>
      <ConnectButton client={client} wallets={wallets} />    
    </div>
  );
}

Deploy Application

To host your static web application on decentralized storage, run:

npx thirdweb deploy --app

By running this command, your application is built for production and stored using Storage. The built application is uploaded to IPFS, a decentralized storage network, and a unique URL is generated for your application.

This URL serves as a permanent hosting location for your application on the web.

If you have any further questions or encounter any issues during the process, please reach out to thirdweb support at support.thirdweb.com.
