The original open-source hardware wallet — fully auditable firmware for maximum security
Last updated: June 2026
Trezor is the world's first hardware wallet, created by SatoshiLabs in 2014, and remains the gold standard for security-conscious users who prioritize open-source transparency over brand recognition. Unlike Ledger's proprietary firmware and secure element chips, Trezor's entire software stack — firmware, desktop app, and web interface — is fully open source and independently auditable. This means any security researcher can review exactly how your keys are generated, stored, and used. The Trezor Safe 3 and Trezor Model T are the current flagship devices, supporting Bitcoin, Ethereum, Litecoin, Cardano, Solana, and 9,000+ other coins. The companion Trezor Suite desktop app provides a clean portfolio view, coin controls for Bitcoin privacy, and direct interaction with Ethereum dApps via MetaMask or Rabby connection. Trezor does not use a dedicated secure element chip (unlike Ledger), instead relying on the general-purpose MCU and open-source firmware — a tradeoff that enables full auditability at the cost of some resistance to physical extraction attacks. Passphrase support adds an invisible 25th word to the seed phrase, creating a completely hidden wallet that cannot be found even if an attacker has the seed phrase.
