🚀 Quick Start

For React Applications

npm install thirdweb

import { createThirdwebClient } from "thirdweb";
import { ConnectButton, useActiveAccount } from "thirdweb/react";

const client = createThirdwebClient({
  clientId: "YOUR_CLIENT_ID",
});

function App() {
  const account = useActiveAccount();
  console.log("Connected as", account?.address);

  return <ConnectButton client={client} />;
}

For React Native Applications, you'll also need to install the @thirdweb-dev/react-native-adapter package and import it at app startup for polyfills.

For Backend Applications

npm install thirdweb

import { createThirdwebClient, Engine } from "thirdweb";

const client = createThirdwebClient({
  secretKey: "YOUR_SECRET_KEY",
});

const wallet = Engine.serverWallet({
  client,
  address: "0x...",
});

const transaction = transfer({
  contract: getContract({
    client,
    address: "0x...", // token contract
    chain: defineChain(1),
  }),
  to: "0x...", // recipient
  amount: "0.01", // amount in tokens
});

await wallet.enqueueTransaction({
  transaction,
});
