What is Trezor?
Trezor is a pioneer in cryptocurrency hardware wallets, founded in 2013 by SatoshiLabs in Prague. As one of the first hardware wallets ever created, Trezor has established itself as a trusted standard for offline crypto storage, protecting private keys from online threats like hacking, phishing, and malware. The company offers two main models: Trezor Model One and Trezor Model T (now succeeded by Trezor Safe 3 and Safe 5). Hardware wallets work by keeping your private keys isolated on a dedicated device that never connects directly to the internet. When you want to send crypto, the transaction is signed on the device itself and only the signed transaction is transmitted - your keys never leave the hardware. This air-gapped approach makes Trezor fundamentally more secure than software wallets or exchange custody. Trezor supports over 9,000 cryptocurrencies including Bitcoin, Ethereum, and all major ERC-20 tokens. The Trezor Suite desktop and web application provides a clean interface for managing your portfolio, sending and receiving funds, and even buying crypto directly through integrated exchanges. Advanced features include coin control for Bitcoin privacy, Tor integration for anonymous transactions, and support for connecting to third-party wallets like MetaMask and Electrum. The setup process involves generating a recovery seed phrase (12 or 24 words) that serves as a backup of your entire wallet. If your Trezor is lost or damaged, you can restore all your funds on a new device using this seed. The devices also support passphrase protection for creating hidden wallets - an additional security layer beyond the PIN. Trezor is fully open-source, meaning its firmware and hardware designs are publicly auditable. This transparency is a key differentiator from competitors, as it allows the security community to verify there are no backdoors or vulnerabilities. For anyone holding significant cryptocurrency, a Trezor represents essential protection against the growing sophistication of cyber threats.
Why Open Source Matters
Trezor's firmware, bootloader, and hardware schematics are fully open source on GitHub. Any security researcher can audit the code. With Trezor, you can verify.
Shamir Backup: Advanced Recovery
Trezor's Shamir Backup splits the seed into up to 16 shares with a configurable threshold. This is the most secure backup method available in any hardware wallet.
