The Ledger Live SDK primarily supports JavaScript/TypeScript for web and desktop applications, with additional support for Python, Java, and C++ for specific use cases. Our main libraries are written in JavaScript and can be used in Node.js environments, web browsers, and React Native applications. For mobile development, we provide React Native bindings and native iOS/Android libraries when needed for performance-critical operations.
Ledger provides a comprehensive device simulator that emulates the behavior of physical Ledger hardware wallets. The simulator can be used for development and testing without requiring actual devices. Additionally, we offer testing libraries with mock implementations of key functions. For continuous integration environments, we provide Docker images with pre-configured simulators. While testing with physical devices is recommended for final validation, the simulator covers most development scenarios.
Yes, Ledger Live can be integrated with decentralized applications through our Web3 provider implementation. This allows dApps to interact with Ledger hardware wallets for transaction signing and account management. We provide a LedgerConnect library that facilitates this integration, supporting both Ethereum and other EVM-compatible blockchains. The integration maintains security by requiring user confirmation on the device for all transactions while providing a seamless user experience for dApp interactions.
Ledger Live API rate limits vary based on your usage tier. For development and testing, we provide generous limits that should accommodate most development workflows. Production applications may require higher limits based on user count and transaction volume. All API calls are subject to reasonable rate limiting to ensure service stability. Detailed rate limit information is available in the developer dashboard once you register your application. For enterprise needs with high volume requirements, we offer custom solutions with dedicated infrastructure.
Ledger maintains security through multiple layers of protection. All transactions must be confirmed on the device screen, preventing malicious applications from signing unauthorized transactions. Private keys never leave the secure element of Ledger devices. We provide code signing for official libraries and recommend developers verify library integrity before integration. Additionally, we offer security guidelines and best practices documentation, and we conduct security reviews of popular integrations. Users are always in control and must physically confirm transactions on their devices.
