Overview

Rhinestone Wallet combines self-custodial smart accounts with crosschain execution, sessions, and fee sponsorship. Choose how much of the wallet experience you want to build and manage.

Two ways to integrate

Use the SDK to own the wallet interface and account configuration. Use 1auth for a managed passkey onboarding and transaction-approval experience built on the same wallet platform.

1auth
SDK

1auth provides managed passkey onboarding and transaction-approval UI while keeping each wallet self-custodial. Your app integrates the client experience, while your server issues the sponsorship credentials required for transactions.The demo below creates and uses a wallet through real transactions on testnet. Authentication and transactions only begin when you choose an action.Get started with 1auth →

The Rhinestone SDK is a customizable TypeScript toolkit. You choose the signer and account integration, build the wallet UI, and control how your app prepares, signs, and tracks transactions.With an API credential available in a secure environment and an already configured signer, account creation is compact:

import { RhinestoneSDK } from "@rhinestone/sdk";

const rhinestone = new RhinestoneSDK({
  apiKey: process.env.RHINESTONE_API_KEY,
});

const wallet = await rhinestone.createAccount({
  owners: {
    type: "ecdsa",
    accounts: [signer],
  },
});

const address = wallet.getAddress();

Do not expose your Rhinestone API key in browser code. The SDK tab in the Wallet quickstart covers installation, signer setup, funding, and the complete transaction lifecycle.Continue with the SDK tab →

Which should you choose?

Choose the SDK when wallet UI, signer flexibility, or account configuration differentiates your product. Choose 1auth when you want Rhinestone to provide passkey authentication and approval UI so you can ship a consistent wallet experience faster.

Decision	SDK	1auth
Signer choice	You choose and configure the signer, including passkeys	Managed passkey authentication
Wallet UI	You build and own it	1auth provides onboarding and approval UI
Managed authentication	Not included	Included
Integration responsibilities	Account configuration, UI, signing flow, and transaction lifecycle	Client integration plus server-issued sponsorship credentials

Both paths use Rhinestone’s smart accounts, crosschain execution, sessions, and fee sponsorship. The difference is who owns the authentication and wallet experience, not the underlying capabilities.
