Overview — what Ledger Live Wallet does for developers
Ledger Live Wallet is the official companion application for Ledger hardware devices. It exposes UX surface areas for users to manage accounts, view portfolio data, buy/swap assets, and sign transactions. From a developer perspective, Ledger Live provides curated connectors and integration points so third-party apps can interact with hardware-backed accounts while ensuring private keys never leave the device.

Core integration patterns
There are three common patterns developers use with Ledger Live: (1) **Account discovery** — list user accounts and balances; (2) **Transaction creation** — build transactions server-side or client-side; (3) **Secure signing** — present transaction payloads to the Ledger device for on-device verification and signature. Each flow keeps the private key inside the secure element and uses the device only for signing and user confirmation.

Developer resources and libraries
Ledger maintains SDKs and libraries for interacting with devices and Ledger Live. Use the official Ledger Developer Portal to access SDKs, API references, and Live App submission guidelines. The Developer Portal includes code samples for account derivation, transaction serialization, and signature verification.

Recommended UX & security practices
When designing UIs that interact with Ledger Live, show clear transaction details (amount, recipient, network fees, smart contract data) and prompt users to verify those exact details on their device screen. Avoid masking or truncating critical fields. Always handle errors gracefully and log events for debugging without storing sensitive data such as private keys or raw seeds.

Signing flows — technical summary
Typical signing flow: your app constructs an unsigned transaction, sends it to Ledger Live or the connected device, the device displays the human-readable details, the user approves it on-device, and the device returns a cryptographic signature. Your app then broadcasts the signed transaction to the network. Ensure your transaction formatting matches the target blockchain’s canonical serialization to avoid user confusion.

Testing & sandbox strategy
During development, use testnets and dedicated development keys. Ledger provides example apps and sandbox environments — register your Live App early to test submission and security checks. Always run integration tests that validate signature correctness and edge-case behavior (e.g., fee rounding, reorg handling, and chain reorganizations).

Live Apps — how to extend Ledger Live
Ledger Live supports Live Apps — vetted third-party apps that run within the Ledger Live ecosystem. If you plan to distribute functionality via a Live App, follow Ledger’s submission requirements: code audits, clear privacy policy, and adherence to UX security guidelines. Live Apps give you a way to reach Ledger users while aligning with Ledger’s security posture.

Interacting with dApps & Web3
For Web3 integrations, Ledger Live can be used with popular connectors to expose account addresses and sign messages/transactions. When building dApp connectors, ensure that any contract interaction is clearly described to the user and validate the contract ABI to present meaningful labels on the device during approval.

Privacy, telemetry & data handling
Respect user privacy: avoid transmitting full transaction histories or private metadata to third-party servers without consent. If analytics are required, aggregate and anonymize data. Follow data minimization principles and be transparent in your privacy policy about what Ledger Live data you collect and why.

Security checklist for release
Before publishing integrations, validate: signature verification logic, correct address derivation paths, robust error handling, and clear instructions for users on verifying transactions on device screens. Conduct internal code reviews, static analysis, and where possible, independent security audits.

Compatibility & supported assets
Ledger Live supports a wide set of blockchains and tokens. Confirm which networks you intend to support and test each one individually — differences in address formats, fee models, and signing algorithms can introduce subtle bugs. Refer to the official supported assets list for the most current coverage.

Submitting your integration
When your integration is ready, submit it through the Ledger Developer Portal. Expect a security and UX review. Provide detailed documentation, test vectors, and optional automated tests to accelerate review. Ledger’s review process is designed to protect end users and maintain a high standard of safety.

Ongoing maintenance & user education
Once live, maintain clear release notes and guides. Educate users about phishing risks, how to verify device prompts, and how to update firmware and Ledger Live. Good documentation reduces support burden and improves trust.

Final notes
Building for Ledger Live is an opportunity to offer secure, hardware-backed experiences to users. Prioritize clarity, minimal privilege, and thorough testing. With the right approach, your integration can combine rich functionality with the strong security guarantees that hardware signing provides.
