Ledger® Live Wallet – Getting Started™ Developer Portal
Introduction: What this guide covers
Welcome! This developer-focused guide explains how to get started with the Ledger® Live Wallet and its Developer Portal. We'll walk through essential concepts, setup steps, security best practices, sample code snippets, and resources — all organized with clear headings (H1–H5), practical examples, and a colorful layout to make the learning flow easier.
Estimated reading time: ~8–10 minutes. This post is written to be copy-pasteable as an HTML blog article with headings, code blocks, and a resource helper list.
Why use Ledger Live and the Developer Portal?
Security-first, hardware-backed signing
Ledger devices provide secure, hardware-backed private key storage. Ledger Live exposes user-friendly wallet features while the Developer Portal offers APIs, SDKs, and documentation so you can integrate device-backed signing into apps.
Extensible: apps, plugins, and integrations
Whether you're building a web dApp, a mobile wallet feature, or a custodial integration, the Developer Portal collects SDKs and guidelines to keep integrations secure and compliant with Ledger's UX patterns.
Getting started — step by step
H3: 1. Create a developer account
Head to the Developer Portal and sign up for a developer account. This gives you access to API keys, sandbox environments, and the downloadable SDKs. Keep your credentials private and never share API keys in public repos.
H3: 2. Install Ledger Live & connect a device
Download Ledger Live on your desktop or mobile device. Use a supported Ledger device (e.g., Ledger Nano S Plus or Nano X). Follow device onboarding: create a PIN, write down the recovery phrase, and install the Ledger Live Manager apps.
H3: 3. Choose an integration path
Options include:
- Client-side integration using Bridge/USB/WebHID to interact with Ledger hardware
- Server-side signing with user approvals via Ledger Live Companion
- Using official SDKs (JavaScript, Swift, Kotlin) published in the Developer Portal
H4: Quick local dev checklist
- Install Node.js (LTS) or your platform SDK
- Install the Ledger SDK package for your language
- Connect device via USB/WebHID and enable developer mode if needed
- Keep a test account and small test funds — never share your main recovery phrase
H4: Example: minimal JavaScript snippet
// Pseudo-example: request device & sign (illustrative only)
import TransportWebHID from "@ledgerhq/hw-transport-webhid";
import AppEth from "@ledgerhq/hw-app-eth";
async function signSample(){
const transport = await TransportWebHID.create();
const eth = new AppEth(transport);
const addr = await eth.getAddress("44'/60'/0'/0/0");
console.log('Address:', addr.address);
// sign transaction...
}
H5: Note on versions & compatibility
Always pin SDK versions and monitor release notes in the Developer Portal. Hardware firmware and Live app updates may require SDK updates to maintain compatibility.
Best practices & security checklist
Secure key handling
Never export private keys. Use the device to sign and keep recovery phrases offline. Implement server-side rate limiting and obfuscate logs to avoid leaking sensitive identifiers.
UX patterns for user prompts
Be explicit about what the user is signing. Show readable transaction summaries, request explicit confirmation steps, and include fallback UX if the device is disconnected.
H4: Testing & audits
- Unit-test your signing flows
- Use sandbox networks for test transactions
- Conduct security audits and threat models before production

Putting it all together: sample workflow
- Sign up for the Developer Portal and get sandbox API keys.
- Install Ledger Live and connect a test device.
- Install the required SDK and create a local dev app.
- Request device connection using WebHID or Bridge; display the address to the user.
- Prepare transaction payload client-side; send to device for signing.
- Send signed payload to the network / relay server and confirm transaction status.
Sample UX microcopy (what you show the user)
"Connect your Ledger Device and confirm the transaction on your device screen. You will see the amount, recipient address, and the network fee. Approve to continue."
H5: Debugging tips
If the device does not respond, check USB permissions, browser WebHID support, and that the Ledger Live companion (if used) is running. Use logging sparingly and never log sensitive payloads.
