Start Building Today🌐 Harnessing the Ledger Live SDK for Unmatched Digital Asset Integration
The **Ledger Live SDK** is the definitive toolkit for connecting your platform to the world's most trusted **hardware wallet** base. Our solution enables native **dApp integration**, allowing your users to interact with your services while their private keys remain secured by their Ledger **secure crypto wallet** device, ensuring the gold standard of **digital asset security**.
Native Hardware Wallet Connectivity
The **Ledger Live SDK** handles all low-level communication complexities with the **hardware wallet**. This simplifies development, allowing you to focus purely on your application logic while ensuring secure, verified transaction signing occurs on the Ledger device. This crucial layer of **offline security** is abstracted for the best user experience.
Comprehensive Multi-Chain Support
Our **Ledger Live API** provides out-of-the-box compatibility with a vast range of networks. Whether you are building on Bitcoin, Ethereum, Solana, or Layer-2 solutions, the SDK ensures your **digital asset integration** maintains full integrity across all supported chains. Access standardized methods for balance checks, transaction history, and execution across this diverse **multi-chain support** architecture.
Seamless User Onboarding
By leveraging the **Ledger Live SDK**, you eliminate the friction of external third-party **secure crypto wallet** installations. Users are already logged into the **Ledger Live** environment, streamlining the process from discovery to transaction. This high trust environment leads to significantly higher conversion rates for **dApp integration** services.
👨💻 Step-by-Step Ledger Live API Integration
Initialize the Ledger Live SDK
Start by including the **Ledger Live SDK** package in your project. This module establishes the bridge communication channel with the running **Ledger Live** desktop application. Proper initialization is key to ensuring secure data exchange and **hardware wallet connectivity**.
const sdk = getLedgerLiveSDK({
projectId: 'YOUR_DEVELOPER_ID',
bridgeURL: 'http://localhost:8435', // Standard Bridge Port
});
Request Account Access and Digital Asset Data
Use the Ledger Live API methods to securely request access to the user's available **digital asset** accounts. The user must approve this access request directly within their **secure crypto wallet** interface. This process adheres to strict privacy and **dApp integration** standards.
currencies: ['ethereum', 'bitcoin'],
allowAddAccount: true,
});
// Now you can read balances or transaction history
Build and Sign a Secure Transaction
Construct your transaction data within your application. The crucial step is delegating the signing process to the **Ledger Live SDK**. This ensures the sensitive private key never leaves the **hardware wallet** environment, guaranteeing absolute **digital asset security** and **multi-chain support** consistency.
const signature = await sdk.transaction.signAndBroadcast({
account, rawTransaction: rawTx,
status: 'user_verification_required',
});
This finalizes the **dApp integration**. The user verifies the transaction on their device screen, confirming the core principle of **hardware wallet connectivity** security. Once approved, the SDK broadcasts the signed transaction to the network.
🔒 Digital Asset Security Through the Ledger Live Vetting Process
Every service seeking integration via the **Ledger Live SDK** must undergo a rigorous vetting process. This commitment to security ensures that every partner upholds the high standards expected by Ledger's millions of **secure crypto wallet** users. This protects our community from malicious dApps and phishing attempts, reinforcing trust in **hardware wallet connectivity**.
Threat Model Review
We perform deep security audits, analyzing the application's unique threat model. This ensures that the integration with the **Ledger Live API** is robust against known vulnerabilities and that user interaction is explicitly clear, preventing transactional ambiguity which is crucial for maintaining **digital asset security** in **multi-chain support** environments.
Code Transparency and Audits
While the **Ledger Live SDK** is the bridge, the underlying application must demonstrate transparency. We require access to repository code and relevant security audit reports to ensure no hidden backdoors or insecure data handling practices threaten the user's **secure crypto wallet** environment.
Continuous Integration Compliance
Compliance is not a one-time process. Our development guidelines require partners to maintain adherence to all security updates and protocols issued for the **Ledger Live SDK**. Regular health checks and system monitoring ensure your continued and safe access to the **Developer Portal**'s resources.
❓ Technical FAQs for SDK Implementers
The **Ledger Live API** (Application Programming Interface) refers to the set of endpoints and protocols exposed by the core Ledger Live application (desktop/mobile) that allow third-party services to query and broadcast data. The **Ledger Live SDK** (Software Development Kit) is the ready-to-use JavaScript library that encapsulates these API calls, handles the handshake, manages the communication bridge, and simplifies the integration of **hardware wallet connectivity** for developers. The SDK is your primary tool for **dApp integration**.
Absolutely not. The core tenet of Ledger's **digital asset security** model is that the private keys and the **Recovery Seed** never leave the secure element of the Ledger **hardware wallet** device. The **Ledger Live SDK** and API are designed for "sign-and-broadcast" functionality. Your application constructs an unsigned transaction, sends it via the SDK to Ledger Live, which sends it to the device for signing, and the signed transaction is returned for broadcasting. Your platform never handles sensitive cryptographic material from the **secure crypto wallet**.
The **multi-chain support** is built into Ledger Live’s core architecture. When integrating a new **digital asset**, the Ledger Live team handles the complexity of adding its specific derivation paths and transaction formats. The **Ledger Live SDK** then provides a unified, chain-agnostic method (`sdk.transaction.signAndBroadcast`) that works universally, abstracting away the specifics of the blockchain. This allows developers to rely on consistent function calls for diverse **digital asset integration**.
Transaction latency using the **Ledger Live SDK** bridge is highly dependent on three factors: network congestion, the complexity of the transaction (e.g., simple transfer vs. complex smart contract interaction), and the time the user takes to verify and approve the transaction on their **hardware wallet**. The communication bridge itself is highly optimized and local (running on the user's machine), minimizing transmission delay between the **dApp integration** layer and the **secure crypto wallet**. Under normal conditions, the digital signing and return handshake are near-instantaneous once user approval is given.
After completing your technical implementation using the **Ledger Live SDK**, you must submit your application through the **Developer Portal**'s formal listing process. This involves providing documentation, undergoing the security vetting mentioned above, and demonstrating full compliance with our UI/UX guidelines. Successful completion of this audit allows your service to be natively featured within the Ledger Live application, granting you direct visibility to millions of **secure crypto wallet** users ready for **digital asset integration**.
