# Embedded Wallet SDKs

> Integrate Rain embedded wallets into your iOS or Android application.

Rain's mobile SDKs let you authenticate users, create and manage embedded wallets, retrieve balances, and send transactions directly from your application.

Choose your development platform to get started.

      <td>Swift</td>
      <td>iOS 17+, Swift 6.1, Xcode 16.3</td>

      <td>**Android**</td>
      <td>Kotlin</td>
      <td>Android API 28+, compile SDK 36</td>
    </tr>
  </tbody>
</table>

Each SDK has dedicated installation instructions, configuration guidance, and a quickstart that walks you through authenticating a user, creating a wallet, and sending your first transaction.

## Using existing wallet providers

If your application already uses another wallet provider, you can integrate that provider with Rain instead of creating new wallets.

Rain provides adapters for [Portal](https://www.portalhq.io/), [Privy](https://www.privy.io/), and [Turnkey](https://www.turnkey.com/). These adapters expose a consistent `RainClient` interface while authentication and key management remain with your existing provider.

See [Third-party wallet providers](/sdks/embedded-wallets/third-party-providers) for installation and configuration.

## Explore wallet guides

Once you've integrated the SDK, explore the wallet guides for instructions on implementing individual features.
