IDP SDK Overview

The Swig IDP SDK is the sign-in layer for Swig apps.

Use it when your product needs to authenticate a user first, then continue with a persisted Swig session that another Swig product can use.

It lives in swig-idp-sdk and currently ships as @swig-wallet/expo-idp-sdk.

What this SDK is for

• user sign-in with OAuth, email OTP, or SMS OTP
• browser or Expo-native auth flows
• isolated-host redirects that return a Swig session
• handing that session off to wallet or policy flows afterward

What this SDK is not for

• transaction preparation
• paymaster operations
• policy management in the developer portal
• direct protocol instruction building

Use Developer SDK for hosted wallet operations after login, or Protocol SDK for direct protocol integration.

Choose your path

If you are building…	Start here
an Expo or React Native app	Expo and React Native Apps
a browser app with redirect-based auth	Browser Apps
the sign-in entrypoint itself	Choose an Auth Method
the session and security boundary	Sessions and Security

What you get back

Every successful auth flow ends with a persisted Swig session. The session contains:

• configAddress
• walletAddress
• roleId
• authFlow

That session is the bridge into the next layer of the stack.

Developer SDK

Use the session to continue into hosted wallet creation and transaction flows

Protocol SDK

Use the session if your app will integrate with Swig wallets directly
