Step 1: **Private Key Generation** and Device Initialization
The moment you power up your **Nano Device** is the moment your **Private Key Generation** begins. This process is the foundation of your entire **Self-Custody Journey**. The cryptographic keys are randomly generated and stored within the device's secure element chip. This chip is physically designed to isolate the keys from your internet-connected computer, ensuring maximum **Digital Asset Security** from the start.
Isolated Secure Element
Your **Private Key Generation** occurs in a CC EAL5+ certified chip. This secure element is tamper-proof and ensures that your keys are *never* transmitted, even during the initial **Wallet Setup**. The keys are essentially born and live their life inside the **Nano Device**, a core principle of reliable **Hardware Wallet Integration**.
Physical PIN Entry
The **Wallet Setup** requires you to set a PIN directly on the **Nano Device**'s screen using its buttons. This physical input method is immune to computer malware or keyloggers, reinforcing your **Digital Asset Security**. You must enter this PIN every time you want to access your funds or perform any function in the **Cryptocurrency Wallet**.
Verified **Key Generation**
The randomness used for **Private Key Generation** is cryptographically secure. The device generates the keys, and the subsequent **24-Word Recovery Phrase** is merely a human-readable representation of that key. This process is auditable and ensures no backdoors exist, upholding the integrity of the **Official Site**'s security promise.
Step 2: Securing Your **24-Word Recovery Phrase** (The Master Key)
The **24-Word Recovery Phrase** is the non-negotiable backup for your entire **Cryptocurrency Wallet**. It is the key to restoring access to your funds if your **Nano Device** is lost, stolen, or damaged. This phrase is shown only once, *only* on the device, during the initial **Wallet Setup**. Its security is synonymous with your **Digital Asset Security**.
The **Recovery Phrase** Protocol
You **MUST** write down the **24-Word Recovery Phrase** on the physical sheets provided in your package. Do not take photos, type it, or store it digitally. After writing it, the **Nano Device** will prompt you to verify a few random words to confirm you recorded them correctly. This mandatory **Initial Security Check** ensures the **Wallet Setup** is robust before proceeding.
- Golden Rule: The phrase never leaves the device's screen and never enters the computer.
- Redundancy: Store multiple copies in separate, secure, and physically protected locations.
Embracing the **Self-Custody Journey**
Securing your **24-Word Recovery Phrase** is your primary responsibility in the **Self-Custody Journey**. If anyone gains access to this phrase, they gain total control over your **Cryptocurrency Wallet** and all funds. The **Hardware Wallet Integration** protects your online usage, but this phrase protects your physical and disaster recovery scenario. Treat it with the utmost secrecy—it is more valuable than any password.
Remember, Ledger will **NEVER** ask you for your **24-Word Recovery Phrase**. Any prompt requesting it is a fraudulent attempt to compromise your **Digital Asset Security**.
Step 3: **Hardware Wallet Integration** via Ledger Live
The final stage of your **Wallet Setup** involves connecting your secured **Nano Device** to the Ledger Live application. This process is initiated directly from **Ledger.com/Start** and establishes the bridge between your physical key storage and the digital blockchain world, enabling you to manage your **Cryptocurrency Wallet**.
The **Initial Security Check**
Download the Ledger Live app only from the **Official Site** as directed by **Ledger.com/Start**. Once installed, select the "Set up a new Ledger device" option. Ledger Live will then perform a **Genuine Check**. This check uses a cryptographic challenge to verify that your **Nano Device** is a legitimate product and has not been tampered with. This is a mandatory safety gate before any **Hardware Wallet Integration** proceeds.
*The check verifies the device’s internal signature, confirming its authenticity before the **Wallet Setup** is complete.*
Creating Your **Cryptocurrency Wallet** Accounts
Once integrated, use the Manager tab to install the specific coin applications (like Bitcoin, Ethereum, etc.) onto your **Nano Device**. Then, go to the Accounts section and click "Add Account." The **Cryptocurrency Wallet** accounts are then derived from your master **Private Key Generation**, and the app synchronizes with the blockchain to show your balances. This establishes your ability to perform transactions and fully control your funds in your **Self-Custody Journey**.
*To add an account, the device must be unlocked, and the corresponding coin app must be open on the **Nano Device**.*
Congratulations on Completing Your **Wallet Setup**!
You have successfully completed the official **Ledger.com/Start** guide. You now possess a fully secured **Cryptocurrency Wallet**, backed by best-in-class **Digital Asset Security** and the power of true **Self-Custody**. Keep your **24-Word Recovery Phrase** safe, and always verify transaction details on your **Nano Device**.
