Phantom React SDK - Phantom developer documentation

The Phantom Connect React SDK provides React hooks for connecting to existing Phantom user wallets in your React apps with native transaction support across multiple blockchains.

Features

Built for React: Provides React hooks (usePhantom, useModal) and a provider component for app-level configuration.
Multi-chain support: Solana (available now), other chains coming soon.
Connection modal: Built-in, customizable modal for connecting users to Phantom.
Flexible authentication providers: OAuth (Google, Apple), browser extension, and injected providers.
User wallet integration: Connects to existing Phantom user wallets using Phantom Connect.
TypeScript support: Fully typed API surface.

Security

The Phantom Connect React SDK connects to existing Phantom user wallets, ensuring:

Users control their own wallets and private keys.
Integration with Phantom’s secure wallet infrastructure.
No private key handling in your application.
User maintains full control of their assets.

Prerequisites

Register your app: Sign up or log in to the Phantom Portal and register your app.
Obtain your App ID:
- In Phantom Portal, expand your app in the left navigation, then select Set Up.
- Your App ID appears at the top of the page.
Allowlist your domains and redirect URLs: Add your app’s domains and redirect URLs in the Phantom Portal to enable wallet connections.

Authentication configuration

When using OAuth providers (google, apple), you’ll need to configure authentication options:

authOptions: {
  redirectUrl: "https://yourapp.com/auth/callback", // Your callback page
}

Important notes about redirectUrl:

Must be an existing page/route in your application
Must be whitelisted in your Phantom Portal app configuration
This is where users will be redirected after completing OAuth authentication
Required for google and apple providers
Not required for injected provider

Installation

npm install @phantom/react-sdk

Dependencies

Install additional dependencies based on the networks you want to support:

Network support	Required dependencies
Solana	`@solana/web3.js` OR `@solana/kit`
Ethereum/EVM	`viem`

Example for Solana and Ethereum support:

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

Quick start

import { PhantomProvider, useModal, darkTheme, usePhantom } from "@phantom/react-sdk";
import { AddressType } from "@phantom/browser-sdk";

function App() {
  return (
    <PhantomProvider
      config={{
        providers: ["google", "apple", "injected", "deeplink"], // Enabled auth methods
        appId: "your-app-id", // Get your app ID from phantom.com/portal
        addressTypes: [AddressType.solana, AddressType.ethereum],
        authOptions: {
          redirectUrl: "https://yourapp.com/auth/callback", // Must be whitelisted in Phantom Portal
        },
      }}
      theme={darkTheme}
      appIcon="https://your-app.com/icon.png"
      appName="Your App Name"
    >
      <WalletComponent />
    </PhantomProvider>
  );
}

function WalletComponent() {
  const { open, close, isOpened } = useModal();
  const { isConnected, user } = usePhantom();

  if (isConnected) {
    return (
      <div>
        <p>Connected</p>
      </div>
    );
  }

  return <button onClick={open}>Connect Wallet</button>;
}

The SDK includes a built-in connection modal UI that provides a user-friendly interface for connecting to Phantom. The modal supports multiple connection methods (Google, Apple, browser extension) and handles all connection logic automatically. To use the modal, pass a theme prop to PhantomProvider and use the useModal() hook to control visibility:

import { PhantomProvider, useModal, darkTheme, usePhantom } from "@phantom/react-sdk";
import { AddressType } from "@phantom/browser-sdk";

function App() {
  return (
    <PhantomProvider
      config={{
        providers: ["google", "apple", "injected"],
        appId: "your-app-id",
        addressTypes: [AddressType.solana, AddressType.ethereum],
      }}
      theme={darkTheme} // or lightTheme, or custom theme object
      appIcon="https://your-app.com/icon.png"
      appName="Your App Name"
    >
      <WalletComponent />
    </PhantomProvider>
  );
}

function WalletComponent() {
  const { open, close, isOpened } = useModal();
  const { isConnected } = usePhantom();

  if (isConnected) {
    return (
      <div>
        <p>Connected</p>
      </div>
    );
  }

  return <button onClick={open}>Connect Wallet</button>;
}

Modal Features:

Multiple Auth Providers: Google, Apple, browser extension
Automatic Provider Detection: Shows browser extension option when Phantom is installed
Mobile Support: Displays deeplink option for Phantom mobile app on mobile devices
Error Handling: Clear error messages displayed in the modal
Loading States: Visual feedback during connection attempts
Responsive Design: Optimized for both mobile and desktop

ConnectButton Component

A ready-to-use button component that handles the complete connection flow:

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

function Header() {
  return (
    <div>
      {/* Default: Shows first available address */}
      <ConnectButton />

      {/* Show specific address type */}
      <ConnectButton addressType={AddressType.solana} />
      <ConnectButton addressType={AddressType.ethereum} />

      {/* Full width button */}
      <ConnectButton fullWidth />
    </div>
  );
}

ConnectButton features:

When disconnected: Opens connection modal with auth provider options
When connected: Displays truncated address and opens wallet management modal
Uses theme styling for consistent appearance

ConnectBox component

An inline embedded component that displays the connection UI directly in your page layout (without a modal backdrop). Perfect for auth callback pages or when you want a more integrated connection experience. The component automatically handles all connection states including loading, error, and success during the auth callback flow.

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

function AuthCallbackPage() {
  return (
    <div>
      <h1>Connecting to Phantom...</h1>
      <ConnectBox />
    </div>
  );
}

Props:

Property	Type	Default	Description
`maxWidth`	`string \| number`	`"350px"`	Maximum width of the box
`transparent`	`boolean`	`false`	Removes background, border, and shadow for a transparent appearance
`appIcon`	`string`	—	URL to your app icon (optional, can also be set via `PhantomProvider`)
`appName`	`string`	—	Your app name (optional, can also be set via `PhantomProvider`)

Usage Examples:

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

// Default usage
<ConnectBox />

// Custom width
<ConnectBox maxWidth="500px" />

// Transparent (no background/border)
<ConnectBox transparent />

// Custom width with transparent
<ConnectBox maxWidth={600} transparent />

ConnectBox Features:

Inline embedded: Renders directly in page flow (not as a floating modal)
Auto state management: Automatically shows connection/login UI when disconnected, wallet info when connected
Auth callback support: Handles loading and error states during OAuth callback flows
No close button: Designed for embedded use cases where users shouldn’t dismiss the UI
Theme-aware: Uses your configured theme for consistent styling

Use ConnectBox for auth callback pages: When using OAuth providers (Google, Apple), users are redirected to your callback URL after authentication. Place ConnectBox on this page to automatically handle the auth flow completion with proper loading and error states.

Theming

The SDK includes pre-built themes and supports full customization to match your app’s design.

Pre-built themes

Use the included darkTheme or lightTheme:

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

// Dark theme
<PhantomProvider config={config} theme={darkTheme} appIcon="..." appName="...">
  <App />
</PhantomProvider>

// Light theme
<PhantomProvider config={config} theme={lightTheme} appIcon="..." appName="...">
  <App />
</PhantomProvider>

Custom themes

Create a custom theme object to fully control the modal’s appearance:

const customTheme = {
  background: "#1a1a1a",         // Background color for modal
  text: "#ffffff",               // Primary text color
  secondary: "#98979C",          // Secondary color for text, borders, dividers
  brand: "#ab9ff2",              // Brand/primary action color
  error: "#ff4444",              // Error state color
  success: "#00ff00",            // Success state color
  borderRadius: "16px",          // Border radius for buttons and modal
  overlay: "rgba(0, 0, 0, 0.8)", // Overlay background color (with opacity)
};

<PhantomProvider config={config} theme={customTheme} appIcon="..." appName="...">
  <App />
</PhantomProvider>

Property	Description	Example
`background`	Modal background color	`"#1a1a1a"`
`text`	Primary text color	`"#ffffff"`
`secondary`	Secondary text, borders, and dividers	`"#98979C"`
`brand`	Brand/primary action color	`"#ab9ff2"`
`error`	Error state color	`"#ff4444"`
`success`	Success state color	`"#00ff00"`
`borderRadius`	Border radius for buttons and modal	`"16px"`
`overlay`	Modal overlay background (supports opacity)	`"rgba(0, 0, 0, 0.8)"`

The secondary color must be a hex color value (e.g., #98979C) as it’s used to derive auxiliary colors with opacity.

Chain-Specific Hooks

The React SDK provides dedicated hooks for each blockchain:

useSolana hook

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

function SolanaOperations() {
  const { solana, isAvailable } = useSolana();

  // Check if Solana is available before using it
  if (!isAvailable) {
    return <div>Solana is not available for the current wallet</div>;
  }

  const signMessage = async () => {
    const signature = await solana.signMessage("Hello Solana!");
    console.log("Signature:", signature);
  };

  const signAndSendTransaction = async () => {
    const result = await solana.signAndSendTransaction(transaction);
    console.log("Transaction sent:", result.hash);
  };

  const switchNetwork = async () => {
    await solana.switchNetwork('devnet');
  };

  return (
    <div>
      <button onClick={signMessage}>Sign Message</button>
      <button onClick={signAndSendTransaction}>Send Transaction</button>
      <button onClick={switchNetwork}>Switch to Devnet</button>
      <p>Connected: {solana.isConnected ? 'Yes' : 'No'}</p>
    </div>
  );
}

useEthereum hook

EVM support for Phantom Connect embedded wallets will go live later in 2026.

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

function EthereumOperations() {
  const { ethereum, isAvailable } = useEthereum();

  // Check if Ethereum is available before using it
  if (!isAvailable) {
    return <div>Ethereum is not available for the current wallet</div>;
  }

  const signPersonalMessage = async () => {
    const accounts = await ethereum.getAccounts();
    const signature = await ethereum.signPersonalMessage("Hello Ethereum!", accounts[0]);
    console.log("Signature:", signature);
  };

  const sendTransaction = async () => {
    const result = await ethereum.sendTransaction({
      to: "0x742d35Cc6634C0532925a3b8D4C8db86fB5C4A7E",
      value: "1000000000000000000", // 1 ETH in wei
      gas: "21000",
    });
    console.log("Transaction sent:", result.hash);
  };

  const switchChain = async () => {
    await ethereum.switchChain(137); // Switch to Polygon
  };

  return (
    <div>
      <button onClick={signPersonalMessage}>Sign Personal Message</button>
      <button onClick={sendTransaction}>Send Transaction</button>
      <button onClick={switchChain}>Switch to Polygon</button>
      <p>Connected: {ethereum.isConnected ? 'Yes' : 'No'}</p>
    </div>
  );
}

Auto-Confirm Hook (Injected Provider Only)

The SDK provides auto-confirm functionality that allows automatic transaction confirmation for specified chains.

useAutoConfirm hook

import { useAutoConfirm, NetworkId } from "@phantom/react-sdk";

function AutoConfirmControls() {
  const {
    enable,
    disable, 
    status,
    supportedChains,
    isLoading,
    error,
  } = useAutoConfirm();

  const handleEnable = async () => {
    // Enable auto-confirm for specific chains
    const result = await enable({
      chains: [NetworkId.SOLANA_DEVNET, NetworkId.ETHEREUM_MAINNET]
    });
    console.log("Auto-confirm enabled:", result);
  };

  const handleDisable = async () => {
    await disable();
    console.log("Auto-confirm disabled");
  };

  return (
    <div>
      <p>Status: {status?.enabled ? "Enabled" : "Disabled"}</p>
      <button onClick={handleEnable} disabled={isLoading}>
        Enable Auto-Confirm
      </button>
      <button onClick={handleDisable} disabled={isLoading}>
        Disable Auto-Confirm
      </button>
    </div>
  );
}

Wallet Discovery Hook

useDiscoveredWallets

Get discovered injected wallets with automatic loading and error states. Discovers wallets using Wallet Standard (Solana) and EIP-6963 (Ethereum) standards.

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

function WalletSelector() {
  const { wallets, isLoading, error, refetch } = useDiscoveredWallets();

  if (isLoading) {
    return <div>Discovering wallets...</div>;
  }

  if (error) {
    return <div>Error discovering wallets: {error.message}</div>;
  }

  return (
    <div>
      <h3>Available Wallets</h3>
      {wallets.map((wallet) => (
        <div key={wallet.id}>
          <img src={wallet.icon} alt={wallet.name} width={24} />
          <span>{wallet.name}</span>
        </div>
      ))}
      <button onClick={refetch}>Refresh</button>
    </div>
  );
}

Returns:

Property	Type	Description
`wallets`	`InjectedWalletInfo[]`	Array of discovered wallet information
`isLoading`	`boolean`	`true` while discovery is in progress
`error`	`Error \| null`	Error object if discovery fails
`refetch`	`() => Promise<void>`	Function to manually refresh the wallet list

SDK Initialization

The SDK provides an isLoading state to track when initialization and autoconnect are in progress:

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

function App() {
  const { isLoading } = usePhantom();
  const { connect } = useConnect();

  // Show loading state while SDK initializes
  if (isLoading) {
    return (
      <div>
        <h1>Initializing Phantom SDK...</h1>
        <p>Please wait...</p>
      </div>
    );
  }

  // SDK is ready
  return (
    <div>
      <h1>Welcome!</h1>
      <button onClick={() => connect({ provider: "injected" })}>
        Connect Wallet
      </button>
    </div>
  );
}

Debug Configuration

Configure debug logging by passing a debugConfig prop to PhantomProvider:

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

function App() {
  const [debugMessages, setDebugMessages] = useState([]);

  const debugConfig = {
    enabled: true,
    level: DebugLevel.INFO,
    callback: (message) => {
      setDebugMessages((prev) => [...prev, message]);
    },
  };

  return (
    <PhantomProvider config={config} debugConfig={debugConfig}>
      <YourApp />
    </PhantomProvider>
  );
}
