⚠️ This SDK is deprecated and no longer maintained.

The Kotlin Wallet SDK has been discontinued. There is no direct Kotlin/Java successor.

Wallet SDKs remain actively maintained in:

• TypeScript — https://github.com/stellar/typescript-wallet-sdk
• Flutter (Dart) — https://github.com/Soneso/stellar_wallet_flutter_sdk
• Swift — https://github.com/Soneso/stellar-swift-wallet-sdk

If you need to stay on the JVM, you can use the lower-level Java Stellar SDK directly, but you will need to implement SEP protocols (SEP-1/10/12/24/30) yourself.

Kotlin Wallet SDK

Kotlin Wallet SDK is a library that allows developers to build wallet applications on the Stellar network faster. It utilizes Java Stellar SDK to communicate with a Stellar Horizon server.

Dependency

The library is hosted on the Maven Central. To import wallet-sdk library you need to add following dependencies to your code:

Maven:

<dependency>
  <groupId>org.stellar</groupId>
  <artifactId>wallet-sdk</artifactId>
  <version>3.0.0</version>
</dependency>

Gradle (Kotlin):

implementation("org.stellar:wallet-sdk:3.0.0")

Gradle (Groovy):

implementation 'org.stellar:wallet-sdk:3.0.0'

Introduction

Here's a small example creating main wallet class with default configuration connected to testnet network:

  val wallet = Wallet(StellarConfiguration.Testnet)

It should later be re-used across the code, as it has access to various useful children classes. For example, new key pair can be created using it.

  val newKeyPair = wallet.stellar().account().createKeyPair()
