Introducing Kotlin and updated SDKs

Integrating blockchain and web3 functionality into mobile apps can be complex and time-consuming. Developers often find themselves wrestling with low-level APIs, platform differences, and repetitive plumbing – work that slows teams down and increases the risk of bugs.

To address these challenges, we’re excited to introduce our new Kotlin SDK alongside updated Swift and Flutter SDKs, making it easier than ever to integrate Turnkey into your apps.

Native and cross-platform SDKs

Our SDKs are designed to meet developers where you are, whether building for a single platform or targeting multiple devices. With native support for Android and iOS, plus a cross-platform Flutter SDK, teams can integrate Turnkey quickly and consistently without rewriting core functionality.

‍Kotlin: For Android developers, our Kotlin SDK provides native APIs for wallet creation, transaction signing, and key management. It minimizes boilerplate and streamlines integration, letting you ship onchain apps faster without sacrificing reliability.

‍Swift: For iOS and macOS developers, our reworked Swift SDK delivers native support for wallets, transaction signing, and on-device security. It simplifies Turnkey integration, enabling teams to build secure, performant apps efficiently.

‍Flutter: For cross-platform apps, the updated Flutter SDK provides widgets and methods to implement Turnkey functionality consistently across both iOS and Android. Developers can write once and deploy everywhere, maintaining a unified user experience across devices.

Build secure, consistent experiences across devices

By offering both native and cross-platform SDKs, we make it easier for developers to build secure, modern, and consistent experiences across devices. Teams can accelerate adoption of onchain features while reducing integration complexity and minimizing the potential for errors.

Get started

Whether you’re building a mobile-first wallet, a DeFi app, or integrating onchain functionality into existing products, these SDKs provide the tools to move faster and more confidently across all major platforms.
