Quick Summary
Trezor created the hardware wallet category in 2014, predating Ledger, and has maintained a fully open-source firmware and companion software approach as its core differentiation — letting independent security researchers audit the entire stack rather than trusting a closed-source implementation. It appeals specifically to security-conscious users who value open-source transparency alongside the offline key storage that all hardware wallets provide.

Trezor’s claim to having created the hardware wallet category in 2014 comes with a specific philosophical commitment that has persisted throughout its history: fully open-source firmware and software, letting independent security researchers verify every component of the security model rather than asking users to trust a closed-source implementation.
This review covers Trezor’s open-source security model, its hardware options, and how it compares to Ledger.
Fully Open-Source, By Design
Unlike Ledger’s partially closed-source approach to certain security elements, Trezor’s entire firmware and companion software stack is open-source, allowing independent security researchers to audit every component rather than trusting unverifiable closed-source claims.
The Original Hardware Wallet
Trezor’s 2014 launch predates Ledger and is generally credited with creating the hardware wallet category entirely, giving it the longest track record of any hardware wallet maker, with no known incidents of customer fund loss attributable to the hardware itself throughout its history.
Trezor Pricing Breakdown
Trezor Safe 3 — $79 (one-time hardware purchase) Offline private key storage, fully open-source firmware, and support for 1,000+ coins and tokens.
Trezor Safe 5 — $169 (one-time hardware purchase) A color touchscreen, a secure element chip, and the same open-source commitment.
Trezor vs. Ledger
Ledger supports a broader range of cryptocurrencies and tokens (5,500+ versus Trezor’s 1,000+) and offers Bluetooth mobile connectivity on some models. Trezor’s advantage is full open-source transparency across its entire stack, appealing specifically to security researchers and users who value independently verifiable security claims over Ledger’s partially closed-source approach.
Who Should Use Trezor
Security researchers and open-source transparency advocates get a fully auditable hardware wallet stack that Ledger’s partially closed-source approach doesn’t offer.
Users holding mainstream cryptocurrencies get a long-proven, secure hardware option with the category’s longest track record.
Who Should Consider Alternatives
Users holding a wide range of less common tokens should check Ledger’s broader 5,500+ asset support, which may cover specific holdings Trezor doesn’t.
Expert Verdict
Trezor’s full open-source commitment and pioneering history make it a genuinely strong choice for security-conscious users who value independently verifiable transparency, even where Ledger’s broader asset support and additional connectivity options give it an edge for some specific use cases.
International Pricing Notes
Trezor devices are priced in USD globally with regional pricing available in select currencies depending on the purchasing region.
Frequently Asked Questions
Common questions about Trezor, answered by our editorial team.
- Is Trezor more secure than Ledger because it's open source?
- Trezor's fully open-source firmware allows independent security researchers to audit every component, which many security-conscious users consider a meaningful transparency advantage over Ledger's partially closed-source approach to certain security elements. Both brands have strong overall security track records with no major incidents of hardware-level fund loss, so the open-source difference is more about verifiable transparency than a proven practical security gap.
- Which came first, Trezor or Ledger?
- Trezor, created in 2014 by SatoshiLabs, is generally credited as the first commercially available cryptocurrency hardware wallet, predating Ledger (also founded in 2014) and establishing the hardware wallet category that Ledger and other competitors later entered.
- Does Trezor support as many cryptocurrencies as Ledger?
- Trezor supports over 1,000 coins and tokens, a solid range but notably smaller than Ledger's 5,500+ supported assets — worth checking specifically if you hold less common tokens, since one or the other may support your specific assets better.
