#Getting Started

We provide an edge wallet SDK for Android and iOS. This SDK is built on top of the Walt.id Libraries and provides a modern way to build wallet mobile applications.

The primary SDK is a Kotlin Multiplatform module which we recommend using for your Kotlin Compose and Android applications. You can find the source code of the SDK here.

For iOS, we provide Swift-native types over our Kotlin Multiplatform module alongside a SKIE bridge to try and make the developer experience as seamless as possible for Swift developers. You can find the source code of the iOS SDK here.

We also provide two sample applications to help you get started:

• A Kotlin Compose application, which builds to both Android and iOS. Uses the Multiplatform SDK and uses Kotlin Compose for the UI.
• A native iOS application, which builds to iOS only. Uses the iOS SDK and uses Native SwiftUI.
