What the device protects
In Trezor’s implementation, the device uses keys for access and signing. Separating keys is a safeguard, not protection from every deception.
FinFly Explains / Crypto
What a hardware wallet is
A hardware wallet is a separate device for keys and transaction confirmation. Cryptoassets are not files stored inside it: records remain on the blockchain.
Why backup matters
The manufacturer explains that a wallet backup restores access after device loss. Someone obtaining it can gain access without the device itself.
Before approving
FinFly recommends verifying the address and purpose before confirmation. Do not approve an unclear request simply because it appears in a familiar application.
Keep secrets private
Follow the official procedure for your model. Trezor warns against entering a backup on a website, computer or phone at “support’s” request. Never publish it or send it in chat.
