**Ledger Live Integrations** **Developer** FAQs

1. What is the difference between a **dApp** and an asset **Integration**?
Asset **Integrations** focus on adding support for a new **Cryptocurrency** or token's balance, receiving, and sending functionalities. **dApp Integrations** (via Ledger Connect) involve providing a seamless, secure transactional bridge from a decentralized application directly to the user's **Hardware Wallet** through **Ledger Live**.
2. Is the **Ledger SDK** mandatory for all **Ledger Live Integrations**?
Yes, using the **Official Ledger SDK** is highly recommended and in many cases mandatory. It handles the low-level communication and **Security** protocols between the **Ledger Hardware Wallet** and the **Ledger Live** application, ensuring all transactions maintain Ledger’s stringent **Security** standards.
3. What **Blockchain** types are prioritized for new **Digital Assets** **Integration**?
Ledger prioritizes **Blockchain** networks with substantial user adoption and strong **Security** models. We encourage **Integration** proposals for Layer 1, Layer 2, and sidechain **Digital Assets** that follow the **Official** **Developer Portal** guidelines and demonstrate reliable wallet capabilities.
4. How long does the **Integration** review process take after submission?
The review duration for **Ledger Live Integrations** varies based on complexity and the current queue. Comprehensive adherence to the **Ledger Developer Portal**'s guidelines and rigorous pre-testing of your **Secure Transactions** can significantly accelerate the auditing and deployment timeline.
5. Are there any fees associated with becoming an **Official** **Ledger Live Integration**?
There are generally no fees required to submit or maintain an asset **Integration** through the **Official Ledger Developer Portal**. However, specialized services or custom **dApp** partnerships may involve different agreements, always focused on shared growth and maintaining **security**.
6. What is the role of the **Ledger Hardware Wallet** in a third-party **dApp** **Integration**?
The **Hardware Wallet** performs the crucial function of signing the transaction offline. When a user interacts with an integrated **dApp**, the **Ledger Live** application relays the data to the device, which cryptographically signs the transaction using the private keys, ensuring **Secure Transactions** that cannot be compromised by a computer virus.
7. Does the **Developer Portal** offer support for multiple programming languages?
Yes, the **Ledger SDK** components and **API** documentation on the **Official Developer Portal** support various development stacks, including JavaScript/Node.js for front-end **Web3** **dApps** and other languages for core **Blockchain** asset **Integration** logic.
8. How can our project ensure the best possible **Security** during **Integration**?
Adhere strictly to Ledger's transaction parsing and display guidelines. Never ask the user for their **Recovery Seed**. Ensure that the full transaction payload is clearly shown on the **Hardware Wallet** screen for confirmation, enabling truly **Secure Transactions**. This is non-negotiable for **Ledger Live Integrations**.
9. What resources are available besides the **SDK** for new developers?
The **Official Ledger Developer Portal** hosts extensive sample code, detailed tutorials, changelogs for the **API**, and access to a dedicated developer community. These resources are critical for troubleshooting and speeding up the launch of your **Ledger Live Integration**.
10. Does **Ledger Live Integration** support all existing **Crypto** tokens on a supported network?
While Ledger supports the underlying **Blockchain** (like Ethereum), individual tokens require explicit asset **Integration** for full support (icons, names, etc.) within **Ledger Live**. Follow the **Developer Portal**'s token listing process to ensure your **Digital Asset** is fully recognized and managed securely by the **Hardware Wallet** ecosystem.
