#Trezor

Trezor is the original hardware wallet brand (SatoshiLabs, Czech Republic, since 2014). Keys stay offline on the device; you approve sends on the screen. Current lineup is Safe 3 / Safe 5 / Safe 7, managed through Trezor Suite. Open-source firmware is the main pitch versus Ledger. Shamir multi-share backups, passphrase wallets, CoinJoin and Tor for Bitcoin privacy. Strong for BTC/ETH self-custody. Weaker than Ledger on some altcoin / Solana convenience and mobile Bluetooth history (Safe 7 closes that gap).
