Setup React App

Scaffold React App with Phantom Connect

When to use

• User asks to set up a React app with Phantom Connect
• User wants to create a wallet-connected React project
• User wants to scaffold a Phantom integration in React

Workflow

Step 1: Install Dependencies

npm install @phantom/react-sdk @solana/web3.js

Step 2: Configure PhantomProvider

Wrap your app's root component in PhantomProvider with the required configuration:

import { PhantomProvider } from "@phantom/react-sdk";

function App() {
  return (
    <PhantomProvider
      config={{
        appId: "your-app-id-from-phantom-portal",
        providers: ["google", "apple"],
        addressTypes: ["solana", "ethereum"],
      }}
    >
      <YourApp />
    </PhantomProvider>
  );
}

Required config fields:

• appId — Register at Phantom Portal to obtain this.
• providers — Social login providers to enable (e.g. ["google", "apple"]).
• addressTypes — Blockchain address types to request (e.g. ["solana"], ["solana", "ethereum"]).

Step 3: Add the Connect Button

Use the built-in ConnectButton component for the simplest integration:

import { ConnectButton } from "@phantom/react-sdk";

function Navbar() {
  return (
    <nav>
      <ConnectButton />
    </nav>
  );
}

Step 4: Use Hooks for Wallet State

Wire up the core hooks to access wallet state and chain-specific APIs:

import {
  useConnect,
  useAccounts,
  useDisconnect,
  useSolana,
} from "@phantom/react-sdk";

function WalletInfo() {
  const { isConnected } = useConnect();
  const { accounts } = useAccounts();
  const { disconnect } = useDisconnect();
  const solana = useSolana();

  if (!isConnected) {
    return <p>Not connected</p>;
  }

  const solanaAccount = accounts.find((a) => a.chain === "solana");

  return (
    <div>
      <p>Address: {solanaAccount?.address}</p>
      <button
    </div>
  );
}

Step 5: Handle Connection Errors

Always wrap connection logic in try-catch:

import { useConnect } from "@phantom/react-sdk";

function ConnectFlow() {
  const { connect } = useConnect();

  const handleConnect = async () => {
    try {
      await connect();
    } catch (error) {
      console.error("Connection failed:", error);
    }
  };

  return <button Wallet</button>;
}

Important Notes

• Always use signAndSendTransaction — signTransaction is NOT supported for embedded wallets.
• Sessions persist for 7 days from last authentication.
• Register your app at Phantom Portal to get an appId.
