Welcome to the Developer Portal quickstart for Ledger® Live Wallet – Getting Started™. This guide gives developers a concise, practical introduction to connecting, testing, and building on top of Ledger/Wallet experiences. Whether you're integrating a dApp, building tooling for ledger wallet users, or automating tests for hardware-backed signing flows, this page helps you move from zero to first transaction.
Ledger/Wallet hardware and Ledger Live software form a secure foundation for user-controlled keys. As a developer, integrating with ledger wallet systems increases user trust and reduces attack surface by relying on hardware-backed signing. Use Ledger Live to manage device connections, retrieve account metadata, and orchestrate signed transactions in a way users already understand.
The simplest flow is: detect device → open app on device → request public key → build transaction → request signature. The Ledger/Wallet connection can be mediated through Ledger Live or direct APIs; many developer tools rely on the ledger wallet ecosystem for a consistent UX.
// pseudocode example
const connectLedger = async () => {
await detectDevice();
await openAppOnDevice('ethereum');
const pubKey = await getPublicKey();
const tx = buildTransaction(pubKey, { to, amount });
const signature = await requestSignature(tx);
broadcast(signature);
};
Note: Always prompt users to confirm actions on their physical ledger device. Never attempt to bypass device confirmation—this is the core security model of any ledger wallet integration.
When building integrations that interact with Ledger/Wallet devices, automate as much of the non-device logic as possible. Mock device responses for CI tests, and keep a small set of manual end-to-end tests against an actual ledger wallet. Use a dedicated test account and test networks (e.g., testnets) to avoid accidental production transactions.
Integrations that rely on ledger wallet hardware should surface clear instructions: how to connect, which app to open on the device, approximate flow time, and what the user should expect to see on-screen. Provide fallback instructions if the Ledger/Wallet is not detected or the ledger wallet app is out of date.
Hardware wallets like Ledger devices are designed to keep private keys off the host machine. Your integration should assume the host is untrusted. Use well-audited libraries and follow Ledger/Wallet best practices for nonce management, transaction building, and user confirmations. Ensure you validate all user inputs before sending transactions to the ledger wallet for signing.
Search the developer docs for SDKs, sample integrations, and API references for specific chains. Many SDKs provide "transport" layers to communicate with a ledger wallet via USB or Bluetooth. Keep your dependencies up to date and test against the latest Ledger Live releases.
This page mentions keywords to help developers and maintain visibility: Ledger/Wallet, ledger wallet, and the alternate spelling Ledgor Wallet.
