OMS Wallet SDKs provide the same wallet model across TypeScript, React Native, Swift, and Kotlin. Choose the SDK for your application runtime, then follow that SDK’s quickstart and workflow pages.

​
SDK model

Create one OMSWallet entry point from your publishable key. It exposes two clients: Authentication establishes a credential. Automatic wallet selection then selects or creates an Ethereum or Solana wallet and starts the active wallet session. Manual selection leaves authentication pending until the application selects, creates, or imports a wallet. For native Swift, Kotlin, and React Native applications, prefer OIDC ID-token authentication when the provider SDK returns an ID token. Use redirect authentication when sign-in must run through a browser. Fixed OMS relay providers and custom OIDC providers are separate configurations.

​
Choose an SDK

Expo Go cannot load the React Native SDK because it contains native code. Use an Expo development build or a bare React Native application.

​
Common workflows

Each SDK documents the same sequence of developer decisions:
  1. Authenticate the user and activate a wallet.
  2. Restore and manage the wallet session, imported wallets, and direct or remote access grants.
  3. Send EVM transactions or Solana transfers through the prepare, fee-selection, execute, and status lifecycle.
  4. Sign and verify EVM or Solana messages, and sign and verify EIP-712 typed data for Ethereum wallets.
  5. Read EVM balances and transaction history or Solana balances for any address.

Send USDC
