Get API KeysThe Ledger Live API supports multiple authentication methods including API keys for server-to-server communication, OAuth 2.0 for user authorization flows, and hardware wallet authentication for transaction signing. API keys are the primary method for application integration and provide access to general wallet functionality, while OAuth is used when your application needs to access specific user account data with their permission. For maximum security, critical operations like transaction signing require confirmation on a physical Ledger hardware wallet device.
Yes, Ledger provides a comprehensive sandbox environment where developers can test their integrations without using real cryptocurrency or financial resources. The sandbox includes test versions of all Ledger Live wallet functionality, simulated cryptocurrency transactions, and virtual Ledger hardware devices. This allows you to thoroughly test your application's integration with Ledger technology, including transaction flows, error handling, and user experience, before deploying to production. Access to the sandbox environment is available through the Ledger Developer Portal alongside your API credentials.
The Ledger Live wallet API supports over 1,500 cryptocurrency assets across more than 50 different blockchains. This includes major cryptocurrencies like Bitcoin, Ethereum, Polkadot, and Cardano, as well as numerous ERC-20 tokens and other digital assets. The API provides consistent interfaces for interacting with these different blockchains, allowing your application to support multiple cryptocurrencies with minimal additional development effort. Ledger continuously adds support for new blockchains and assets, with updates automatically available through the API without requiring changes to your integration.
Integrating Ledger hardware wallets into web applications involves using the Ledger Live JavaScript libraries that communicate with connected devices through the browser. When a user connects their Ledger device via USB, your application can request the device to perform operations like retrieving public keys, displaying addresses for verification, and signing transactions. The private keys never leave the secure element of the hardware wallet, ensuring maximum security. For web applications, this typically involves using the WebUSB API or Ledger's browser extension to establish communication between the web page and the physical device, with all sensitive operations confirmed directly on the device screen.
The Ledger Live API employs tiered rate limiting based on your account type and usage patterns. Free developer accounts typically have limits of 100 requests per minute and 10,000 requests per day, which is sufficient for development and testing. Production applications can request higher limits based on their specific needs. Rate limits are applied per API key, and responses include headers that indicate your current rate limit status. For high-volume applications, Ledger offers enterprise plans with custom rate limits and dedicated infrastructure. It's recommended to implement proper caching and request optimization in your application to minimize API calls and stay within limits.
