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.

SDK	Language	Requirements
iOS	Swift	iOS 17+, Swift 6.1, Xcode 16.3
Android	Kotlin	Android API 28+, compile SDK 36

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, Privy, and Turnkey. These adapters expose a consistent RainClient interface while authentication and key management remain with your existing provider.

See Third-party wallet providers for installation and configuration.

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