The Trezor Safe 3 is the affordable open-source hardware wallet — a certified EAL6+ secure element and full firmware transparency for $79, the budget pick for self-custody done right.
The Trezor Safe 3 proves you don't need to spend big for serious self-custody. At $79 it brings the same certified EAL6+ secure element as the flagship Safe 5 — the first secure-element chip in the affordable Trezor line — alongside Trezor's fully open-source firmware. For budget-conscious buyers who still want auditable security, it's the obvious choice.
The compromise versus the Safe 5 is the interface: instead of a color touchscreen, the Safe 3 uses a monochrome display with two physical buttons. It's less slick but completely functional, and arguably more robust. You still get the full Trezor Suite app, passphrase protection, Shamir Backup, and support for thousands of coins including Bitcoin, Ethereum and ERC-20 tokens, Litecoin, and Cardano.
It competes head-to-head with Ledger's Nano S Plus, also $79 — the decision comes down to philosophy. The Safe 3 wins on open-source transparency; the Nano S Plus wins on native staking, NFT support, and broader asset coverage including reliable XRP. If your priority is cheap, honest, auditable cold storage for Bitcoin and major coins, the Safe 3 is excellent value.
The best-value open-source hardware wallet: flagship-grade secure-element security and auditable firmware for $79. Its natural rival is the Ledger Nano S Plus — pick the Safe 3 for transparency, the Nano S Plus for staking and wider coin support.
Yes, if you want affordable open-source cold storage. For $79 you get the same EAL6+ secure element as the flagship Safe 5 and fully auditable firmware — excellent value for self-custody.
