How does the Keystone 3 Pro keep crypto private keys offline?
The Keystone 3 Pro uses an air-gapped design, meaning it signs transactions via QR code scanning rather than through USB or direct internet connection. This architecture ensures the private keys never leave the device's secure element during transaction signing.
What coins and blockchains does the Keystone 3 Pro support?
The Keystone 3 Pro supports a broad range of cryptocurrencies including Bitcoin, Ethereum, and various ERC-20 and TRC-10 tokens, among many others. It uses a BIP39 seed phrase for backup, making it compatible with software wallets like MetaMask and BlueWallet.
What is the Tamagotchi NFT feature on the Keystone 3 Pro?
The Keystone 3 Pro incorporates a TRC-10 based chip that supports interactive Tamagotchi-style NFTs, a distinctive feature among hardware wallets. The NFTs can be displayed and interacted with on the device's built-in touchscreen.
How does the Keystone 3 Pro compare to the Ledger and Trezor wallets?
Unlike Ledger and Trezor, which typically connect via USB or Bluetooth for transaction signing, the Keystone 3 Pro's QR-code-only approach provides a fundamentally different security model. This eliminates attack vectors associated with wired or wireless connections but makes the signing process somewhat slower.
