setup-react-app

A setup guide and workflow for scaffolding a React app with Phantom Connect. Phantom Connect adds wallet login, including social sign-in and Solana or Ethereum address support.

In plain words
What is it for?
Installing the required packages, configuring the Phantom provider, and adding a wallet connection button to a React app.
Why use it?
It removes much of the initial setup needed to connect a React project to Phantom wallets.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

setup-react-app scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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 onClick={disconnect}>Disconnect</button>
    </div>
  );
}

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
