Part 7/11:
Private keys are generated within the chip using a true random number generator.
Keys never leave the chip, which signs transactions internally.
The device detects tampering; any breach attempt triggers self-destruction, wiping keys entirely.
Wireless communication between the device and app employs AES-encrypted Bluetooth, maintaining a secure channel. Since its market debut in 2018, Safe Pal boasts no known major security breaches.

While the Safe Pal X1 is impressively equipped for a budget device, notable compromises include:
No desktop software or integration with advanced wallets like Sparrow or Electrum.
No camera or QR code interface—requiring Bluetooth; some users favor air-gapped QR signings.
