Develop App Using thirdweb

Create Application

Thirdweb offers SDKs for a range of programming languages, such as React, React Native, TypeScript, Python, Go, and Unity.

1. In your CLI run the following command:

   npx thirdweb create --app

2. Input your preferences for the command line prompts:

   1. Give your project a name
   2. Choose your network: We will choose EVM
   3. Choose your preferred framework: Next.js, CRA, Vite, React Native, Node.js, or Express
   4. Choose your preferred language: JavaScript or TypeScript

3. Use the React or TypeScript SDK to interact with your application’s functions. See section on “interact with your contract”

Interact With a Contract

thirdweb provides several SDKs to allow you to interact with your contract including: React, React Native, TypeScript, Python, Go, and Unity.

This document will show you how to interact with your contract deployed to Kava using React

View the full React SDK reference in thirdweb’s documentation.

To create a new application pre-configured with thirdweb’s SDKs run and choose your preferred configurations:

npx thirdweb create app --evm

or install it into your existing project by running:

npx thirdweb install

Initialize SDK On Kava

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

import { ThirdwebProvider } from '@thirdweb-dev/react';
import { KavaEvm } from '@thirdweb-dev/chains';

const App = () => {
  return (
    <ThirdwebProvider activeChain={KavaEvm}>
      <YourApp />
    </ThirdwebProvider>
  );
};

Get Contract

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

import { useContract } from '@thirdweb-dev/react';

function App() {
  const { contract, isLoading, error } = useContract('{{contract_address}}');
}

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 { useOwnedNFTs, useContract, useAddress } from '@thirdweb-dev/react';
  
  // Your smart contract address
  const contractAddress = '{{contract_address}}';
  
  function App() {
    const address = useAddress();
    const { contract } = useContract(contractAddress);
    const { data, isLoading, error } = useOwnedNFTs(contract, address);
  }

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

  import { useContractRead, useContract } from '@thirdweb-dev/react';
  
  // Your smart contract address
  const contractAddress = '{{contract_address}}';
  
  function App() {
    const { contract } = useContract(contractAddress);
    const { data, isLoading, error } = useContractRead(contract, 'getName');
  }

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

  import {
    useContractWrite,
    useContract,
    Web3Button,
  } from '@thirdweb-dev/react';
  
  // Your smart contract address
  const contractAddress = '{{contract_address}}';
  
  function App() {
    const { contract } = useContract(contractAddress);
    const { mutateAsync, isLoading, error } = useContractWrite(
      contract,
      'setName'
    );
  
    return (
      <Web3Button
        contractAddress={contractAddress}
        // Calls the "setName" function on your smart contract with "My Name" as the first argument
        action={() => mutateAsync({ args: ['My Name'] })}
      >
        Send Transaction
      </Web3Button>
    );
  }

Connect Wallet

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

import {
  ThirdwebProvider,
  metamaskWallet,
  coinbaseWallet,
  walletConnectV1,
  walletConnect,
  safeWallet,
  paperWallet,
} from '@thirdweb-dev/react';

function MyApp() {
  return (
    <ThirdwebProvider
      supportedWallets={[
        metamaskWallet(),
        coinbaseWallet(),
        walletConnect({
          projectId: 'YOUR_PROJECT_ID', // optional
        }),
        walletConnectV1(),
        safeWallet(),
        paperWallet({
          clientId: 'YOUR_CLIENT_ID', // required
        }),
      ]}
      activeChain={KavaEvm}
    >
      <App />
    </ThirdwebProvider>
  );
}

Add in a connect wallet button to prompt end-users to login with any of the above supported wallets.

import { ConnectWallet } from '@thirdweb-dev/react';

function App() {
  return <ConnectWallet />;
}

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.
