SDKs, APIs, and Documentation

The **Ledger Developer Portal** Tool Stack for **Secure** **dApp** and Exchange Rollout

Core **Blockchain SDK** & Coin Support

Our modular **blockchain SDK** provides the necessary components for interacting with various cryptocurrency networks, including specialized features for **Bitcoin** and high-volume altcoins. It abstracts the complexity of deriving keys and formatting chains, ensuring that your **crypto app development** remains focused on user logic while relying on Ledger's proven **secure** transaction validation process. This core library is essential for integrating new coins and tokens into **Ledger Live** and enabling seamless trades on your **Crypto Exchange**.

**Ledger Live Integrations** API for Trading

The **Ledger Live** API is designed for **dApp** and exchange integration, enabling partners to push live market data, transaction requests, and execution details directly to the **hardware wallet** owner’s screen. This seamless communication pathway ensures users can approve transactions on their device, upholding the principle of "What you see is what you sign" (**secure** signing). For an integrated **Crypto Exchange**, this API is the backbone for delivering transparent and auditable trade flows, critical for maintaining the **Official Page** status.

Testing & Sandbox Environment for Exchange Partners

Before launching your **dApp** or currency integration, utilize our sandbox environment available through the **Ledger Developer Portal**. This provides a replica of the **Ledger Live** and **hardware wallet** interactions, allowing developers to test their **crypto app development** and exchange logic rigorously in a **secure**, controlled setting, mitigating risks before final deployment. Rigorous testing is a prerequisite for all **Ledger Live Integrations**, especially for **Bitcoin Exchange** and other trading functionalities where asset integrity is paramount.

The documentation available on the **Ledger Developer Portal** is continuously updated, providing detailed guides, best practices, and code examples for every aspect of **Ledger Live Integrations** and **secure** **crypto app development**. We make it easy to onboard and start benefiting from the **secure** **hardware wallet** ecosystem immediately, providing specific flow diagrams for integrated **Crypto Exchange** partners.

The **Secure** Element Barrier

Every transaction, from a small transfer to a major **Crypto Exchange** settlement, is protected by the physical isolation of the chip.

Foundation of Trust

Inherent **Security** with Every **Ledger Live Integration**

The defining feature of any **Ledger Live Integration** is the foundational promise of **security**. Every transaction initiated by your **dApp**, coin, or **Crypto Exchange** partner is routed to the **hardware wallet** and confirmed on its **secure** element chip. This physical isolation is the only true defense against online threats, malware, and phishing attacks that could compromise hot wallets or software wallets. By integrating through the **Ledger Developer Portal**, you are providing your users with this non-negotiable layer of safety, especially when dealing with high-value assets like **Bitcoin**.

This security model is particularly vital for **Bitcoin Exchange** functionality, where the risk of interception and fraudulent trade execution is highest. Ledger's architecture ensures that the final exchange details—the exact amount and recipient address—are cryptographically verified by the user on the device itself before signing occurs. This eliminates man-in-the-middle attacks, making every integrated service inherently more trustworthy and solidifying its status as an **Official Page** integration.

  • ⚠ **Seed Phrase Isolation:** Private keys never exposed to the internet or the host computer's operating system.
  • ⚠ **Transaction Validation:** User manually verifies exchange or trade details on the **hardware wallet** screen before authorization.
  • ⚠ **Cryptographic Assurance:** Ledger's libraries ensure all exchange signings are cryptographically **secure** and compliant with blockchain standards.

This level of **security** is the reason why **Ledger Live** is the preferred application for millions of crypto holders. Making your service available via **Ledger Live Integrations** immediately elevates your offering to the gold standard of **secure** **crypto app development**.

The Value of **Official Page** Vetting

When an exchange achieves **Official Page** status through the **Ledger Developer Portal**, they benefit from more than just integration. They gain the credibility that comes from passing a thorough technical and operational audit. This vetting includes rigorous testing of the integration via the **blockchain SDK**, verification of regulatory compliance (KYC/AML procedures where applicable), and an assessment of liquidity and customer support robustness. This commitment to partner due diligence protects the end-user, minimizes counterparty risk, and reinforces the trust associated with the Ledger brand, making the **Ledger Live Integrations** platform the most trusted gateway for **secure** decentralized finance and trading globally.

The **Secure** Trading Lifecycle (**Crypto Exchange** to Hardware Wallet)

Understanding the atomic nature of the transaction flow is key to mastering **Ledger Live Integrations**. The following steps describe how the **blockchain SDK** mediates a **secure** trade, ensuring the user is always in control, even when dealing with high-frequency **Crypto Exchange** actions.

  1. **Request Initiation:** The user selects an integrated **Crypto Exchange** **dApp** in **Ledger Live** and submits a trade request (e.g., swapping **Bitcoin** for an altcoin).
  2. **API Communication & Quote Lock:** The **Ledger Live Integrations** API securely relays the unsigned transaction details, including the locked trade rate and final receiving address, to the **hardware wallet** via the **blockchain SDK**.
  3. **Secure Element Verification:** The raw transaction data is parsed by the Ledger firmware and displayed clearly on the device's physical screen. The private key, locked inside the **secure** element, awaits user command.
  4. **User Confirmation (The Security Checkpoint):** The user manually verifies the trade pair, exact amounts, fees, and final destination address on their **hardware wallet** and presses the physical confirmation buttons. This multi-factor, physical check prevents remote hacking or transaction tampering.
  5. **Cryptographic Signing:** Upon confirmation, the **secure** element generates the digital signature, which is immediately transmitted back to the **Ledger Live** application via the SDK's secure transport protocol.
  6. **Trade Finalization:** **Ledger Live** forwards the signed, authenticated transaction to the integrated **Crypto Exchange** partner for immediate execution and settlement, concluding the fully **secure** trade backed by the **hardware wallet**.

Technical Mandates for Vetted Partners

To maintain the high standards expected of a partner listed on the **Official Page** of **Ledger Live**, developers must adhere to specific technical mandates. This includes supporting the latest iterations of the **blockchain SDK**, ensuring full compatibility with multi-chain assets, and maintaining robust logging and error reporting. Specifically for **Crypto Exchange** platforms, we require clear UI/UX guidelines to ensure the user sees accurate and non-misleading information before signing, which is essential for protecting the integrity of the **hardware wallet** experience. Our testing team works closely with partners to certify these rigorous standards.
