What is Trezor?

Trezor is a cold storage hardware wallet developed by SatoshiLabs in 2014. It was the first Bitcoin hardware wallet, designed to keep private keys offline, away from hackers and malware.

Unlike software wallets (MetaMask, Trust Wallet), Trezor stores keys in a secure chip, requiring physical confirmation for transactions. This makes it immune to remote attacks.

How Trezor Works

Trezor operates as an air-gapped device, meaning it never exposes private keys to the internet. Here’s how it works:

1. Private Key Generation – When setting up, Trezor generates a 24-word recovery seed (BIP39 standard).
2. Secure Signing – Transactions are signed inside the device, and only the signed transaction is sent to the connected computer.
3. PIN & Passphrase Protection – Even if stolen, the wallet requires a PIN and optional passphrase for access.
4. Recovery – If lost, the wallet can be restored using the seed phrase on another Trezor or compatible wallet.
