// WELCOME TO THE SECURE ECOSYSTEM //
Expand your **DApps** and **crypto assets** services directly into the **Ledger Live** application. Leverage our **SDK** to provide millions of users with verifiable transactions and the gold standard of **Secure Hardware Wallet** access. The **Ledger Developer Portal** is your official gateway to the future of decentralized finance.
Explore Integration PathsIntegrating via the **Ledger Developer Portal** means aligning your service with the industry’s most trusted **Secure Hardware Wallet** brand. **Ledger Live** users rely on the cryptographic guarantees of the Secure Element chip. By using our **SDK**, you ensure that your **DApps** and transactions benefit from genuine, verifiable **Blockchain** security. This level of trust is non-negotiable for large-scale adoption in the **crypto assets** space.
The **Ledger Live** application is the primary interface for millions of owners of **Secure Hardware Wallet** devices globally. Your **Integrations** gain immediate, direct exposure to a highly engaged and security-conscious audience. This platform provides unparalleled organic reach for new **DApps**, staking services, and token support without the need for complex marketing funnels. We facilitate your growth in the secure **crypto assets** domain.
Our comprehensive **SDK** allows for native **Integrations** that feel seamless within the **Ledger Live** environment. Users never have to expose their **private keys** or leave the security perimeter. Whether it's signing a decentralized exchange (DEX) trade or delegating staking rewards, the experience is smooth, fast, and cryptographically verified by the **Secure Hardware Wallet**. This enhanced UX drives high conversion and retention for your **DApps**.
The **Ledger Developer Portal** provides robust **SDKs** designed to simplify the connection between your application and the **Secure Hardware Wallet** ecosystem. Our primary tool is the **Ledger Live** Bridge, which allows your web-based **DApps** to securely communicate with the desktop application, initiating transaction requests that are confirmed on the physical device. This layered approach guarantees **Blockchain** security.
// This example illustrates an abstract call using the Ledger Live API/SDK
// Ensure environment variables and secure contexts are properly initialized.
async function initiateSecureTransaction(recipient, amount, appName) {
try {
console.log(`Initiating transaction for: ${amount} to ${recipient}`);
// 1. Prepare payload using the Ledger SDK for the target blockchain
const transactionPayload = {
network: 'Ethereum', // Or Bitcoin, Solana, etc.
recipient: recipient,
amount: amount,
// Additional parameters required for the specific DApps/Blockchain
data: Buffer.from('smart-contract-call-data').toString('hex')
};
// 2. Call the Ledger Live API/SDK method to secure sign
const signature = await window.LedgerAPI.requestSignature({
path: "44'/60'/0'/0/0", // Derivation Path (Secure Hardware Wallet standard)
payload: transactionPayload,
appName: appName // Name of the integrating DApp/Service
});
// 3. Signature received and verified by the Secure Hardware Wallet
console.log("Transaction successfully signed on Secure Hardware Wallet.");
return signature;
} catch (error) {
console.error("Ledger Signing Error:", error.message);
// Implement exponential backoff and user messaging here
return null;
}
}
Our **technical documentation** on the **Developer Portal** provides explicit, language-specific guides for using the **SDK** to handle device connectivity, **firmware** requirements, error handling, and transaction parsing. Prioritizing correct implementation is key to passing our **security review** and maintaining the integrity of the **Secure Hardware Wallet** connection.
The trust of the **Ledger Live** community is paramount. Therefore, every single **DApps** integration, **crypto assets** service, or staking application that wishes to be featured within the Ledger ecosystem must pass a stringent, mandatory **security review** process. This is the bedrock of our promise: maximum **Blockchain** security for our users' **crypto assets**. The review process is detailed on the **Ledger Developer Portal** and focuses on several key areas.
1. Transaction Integrity & Clear Signing
We verify that the data displayed to the user on their **Secure Hardware Wallet** screen (Clear Signing) precisely matches the data being cryptographically signed by the device. Ambiguous or obfuscated transaction data will result in immediate failure of the **security review**. Users must know exactly what they are signing with their **private keys**.
2. Data Handling & Non-Key Exposure
The **SDK** integration must prove that at no point do user **private keys** or the **recovery phrase** leave the **Secure Hardware Wallet** or enter your application environment. We audit your **API** and client-side code to ensure strict adherence to this fundamental **security protocol** standard, protecting the user's **crypto assets**.
3. **Firmware** Compatibility & Stability
Your integration must be stable across all supported Ledger device models (**Nano S Plus**, **Nano X**) and various **firmware** versions. The **Ledger Developer Portal** provides a testing framework to validate compatibility before submission. Stability ensures a reliable **Ledger Live** experience.
4. User Experience & Disclosure
Beyond code, we review the clarity of your UI and documentation. Users must be clearly informed about risks, fees, and the nature of the **DApps** they are interacting with. Full transparency strengthens the entire **Blockchain** ecosystem.
