Take Control of Your Security with the KeyPal Hardware Wallet — Protect Your BTC Better
1. True Random Number Generator (TRNG) — Building Security from the Source
When generating your recovery phrase, KeyPal 2 uses a True Random Number Generator (TRNG) to provide a high-entropy, unpredictable source of randomness, greatly reducing the risk of brute-force attacks caused by weak entropy.
Unlike software-based pseudo-random number generators (PRNGs), TRNG is driven by physical hardware noise, offering stronger randomness that cannot be predicted or reproduced.
2. Offline Generation & On-Chip Storage — Private Keys Never Touch the Internet
Your recovery phrase is generated entirely offline and securely stored within an independent EAL6+ Secure Element (SE).
KeyPal adopts a dual-chip architecture (MCU + SE) to achieve data isolation, tamper detection, and resistance to physical attacks — ensuring that all sensitive data always remain inside the hardware device.
3. “What You See Is What You Sign” — Full Control Over Every Transaction
Every transaction must be reviewed and confirmed directly on the KeyPal 2 screen, displaying complete details such as amount, recipient address, and transaction fee.
This design ensures that only the user has the final authorization to sign, preventing asset loss from app or network-side tampering.
4. One-Tap NFC Backup to KeyPal Card — Offline, Secure, and Effortless
KeyPal 2 supports encrypted NFC backup of your recovery phrase to the KeyPal Card:
The entire process is completely offline, and the card stores only encrypted data.
Even if the card is lost or stolen, without the correct PIN, your assets remain safe.
The one-tap write operation makes it both secure and efficient, ideal for offline cold storage or portable backups.
