Establish a connection

Connect your Sui dapp to Phantom by requesting user permission to share their public key.

Phantom’s Sui dapp support will be deprecated on September 24, 2026. Do not start new Sui integrations with Phantom. Existing integrations can continue during the transition and should prepare for the deprecation.

Once an application has detected the provider, it can then request to connect to Phantom. This connection request will prompt the user for permission to share their public key, indicating that they are willing to interact further. Users must approve a connection request before the app can make additional requests such as signing a message or sending a transaction.

Once permission is established for the first time, the web application’s domain will be whitelisted for future connection requests. After a connection is established, it is possible for the user to terminate the connection from the Phantom settings UI.

Connect

The recommended and easiest way to connect to Phantom is by calling window.phantom.sui.requestAccount().

const provider = getProvider(); // see "Detecting the Provider"
try {
    const resp = await provider.requestAccount();
    console.log(resp.publicKey.toString());
} catch (err) {
    // { code: 4001, message: 'User rejected the request.' }
}
