Phantom Embedded Wallet SDK

Phantom Embedded enables you to seamlessly onboard users to your application, without requiring them to have previously installed a wallet. With Phantom Embedded, users can create a self custodial wallet with just their Google account and a 4-digit pin. Once created, this wallet will automatically sync with Phantom's mobile and extension apps without the user needing to know their seed phrase or manage any private keys.

In addition to powering wallet creation, Phantom Embedded also comes with a built-in UI for users to view and manage their holdings. This UI serves as a trusted interface for users to sign messages and transactions on your app.

Features

• Create self custodial wallets without leaving your application
• Onboard users via Sign in with Google and a 4-digit pin (no seed phrases)
• Sync embedded wallets with Phantom's mobile and extension apps
• Sign transactions and message on Solana (more chains coming soon)
• View, send, and receive tokens on Solana, Ethereum, Bitcoin, Base, and Polygon
• Pricing: FREE

Quickstart

1. Install the Phantom Embedded SDK

yarn | npm | pnpm add @phantom/wallet-sdk

2. Load the Phantom Embedded wallet in your web application

import {createPhantom} from "@phantom/wallet-sdk"

const opts: CreatePhantomConfig = {
    zIndex: 10_000,
    hideLauncherBeforeOnboarded: true,
}

const App = () => {
    useEffect(() => {
        createPhantom(opts);
    }, []);
...
}

3. Integrate Phantom as you would normally. Whenever a user interacts with Phantom (e.g. window.phantom.solana.connect()), the Phantom Embedded wallet will automatically initialize if the user does not have Phantom already installed.

Configuration

The following optional parameters can be passed as createPhantom({options...}) to customize the Phantom Embedded wallet experience.

Parameter	Type	Description
hideLauncherBeforeOnboarded	boolean	If true, the Phantom Embedded UI will be hidden until the user engages with Phantom. Defaults to false.
colorScheme	string	The background color of the Phantom Embedded iframe, which should be configured to match your site's theme. Can be "light", "dark", or "normal". Defaults to "normal".
zIndex	number	The z-index of the Phantom Embedded UI. Defaults to 10_000.
paddingBottom	number	The number of pixels between the Phantom Embedded UI and the right edge of the web. Defaults to 0.
paddingRight	number	The number of pixels between the Phantom Embedded UI and the bottom edge of the web. Defaults to 0.
paddingTop	number	The number of pixels between the Phantom Embedded UI and the top edge of the web. Defaults to 0.
paddingLeft	number	The number of pixels between the Phantom Embedded UI and the left edge of the web. Defaults to 0.
position	enum	The corner of the app where the Phantom wallet will be displayed. Can be "bottom-right", "bottom-left", "top-right", "top-left". Defaults to "bottom-left".

Controlling the wallet after initialization

The createPhantom method will return an object that allows you to control the embedded wallet after initialization.

Property	Type	Description
show	() => void	Shows the embedded wallet. You only need to call this if you have called hide.
hide	() => void	Hides the embedded wallet. The embedded wallet will now be invisible to users until you call show.

import { createPhantom } from "@phantom/wallet-sdk";

const opts: CreatePhantomConfig = {
  zIndex: 10_000,
  hideLauncherBeforeOnboarded: true,
};
const phantom = createPhantom(opts);

// To hide the embedded wallet
phantom.hide();

// To show the embedded wallet
phantom.show();

Note: Phantom Embedded will not initialize if it detects that the user already has the Phantom extension installed, or if the user is accessing the page from within the Phantom mobile app.

Frequently Asked Questions

How does the embedded wallet work with the Phantom extension?

If the Phantom extension is detected, we will not inject the embedded wallet. Phantom users can continue using their extension like normal.

What does `createPhantom()` do?

The Phantom embedded wallet lives inside an iframe. The `createPhantom` function loads and attaches the iframe to your website.

How do I interact with the embedded wallet?

Once `createPhantom` has been called, `window.phantom.solana` and a compliant wallet-standard provider will also be available in the global scope of your website. This means that most of your existing code for interacting with Solana wallets should work out of the box.

Once a user has onboarded to the embedded wallet, they should be able to click your “connect wallet” button, which gives your website access to their Solana address. After that, signing messages and transactions should just work as normal.

I can't see the embedded wallet on my website. What's wrong?

The most common cause is that you are using a browser with the Phantom extension installed. If the Phantom extension is detected, we will not inject the embedded wallet.

You can temporarily disable the Phantom extension by going to `chrome://extensions` and toggling Phantom off.

How much does this cost?

It's free!
