## Frequently asked questions

### Is the UKey Wallet secure?
End-to-end encryption, physical isolation between hot and cold wallets, and a financial-grade TEE security chip. Private keys are always stored in offline secure chips, fully shielded from network-borne attacks.

### Which chains and cryptocurrencies are supported?
50+ mainstream public chains (Bitcoin, Ethereum, Solana, Avalanche, Tron, etc.) covering 30,000+ crypto tokens for multi-chain asset management.

### Can UKey hardware be used completely offline?
Yes. Key generation and transaction signing happen offline inside the hardware wallet. The companion app only views balances and broadcasts already-signed transactions; the hardware itself never goes online.

### How are wallets backed up and restored?
At wallet creation the user receives a BIP39-standard seed phrase (12 or 24 words). Keeping the seed phrase safe lets the user restore the same assets on any BIP39-compatible wallet, even if every UKey device is lost.

### Is BTC stored on the device?
No. Bitcoin lives on the blockchain. The hardware wallet stores the private keys that authorise spending the BTC.

### What if the device is lost or destroyed?
Recover assets from the BIP39 seed phrase on any compatible hardware or software wallet. The seed phrase, not the device, is the source of truth.

### Does sending BTC require an internet connection?
The signing step is offline and happens inside the hardware wallet. Broadcasting the signed transaction does require network access, which is performed by the companion app on a connected device.
