Trezor Wallet
What is Trezor Wallet?
Trezor WalletAn open-source hardware wallet line by SatoshiLabs that stores cryptocurrency seeds offline and signs transactions through a built-in screen and buttons.
Trezor Wallet is the family of hardware wallets developed by Czech firm SatoshiLabs, including Trezor One, Model T, Safe 3, and Safe 5. The devices are notable for their fully open-source firmware and reference implementation of the BIP-39 mnemonic standard, which SatoshiLabs co-authored. Older Trezor models without a secure element have been shown to be vulnerable to physical fault-injection attacks that can extract the seed from an unlocked device, so SatoshiLabs added a certified secure element to the Safe series. Trezor remains popular with users who prioritize auditability and transparency over closed proprietary chips, often combined with passphrases and multisig for additional defence in depth.
