You plan to buy a Wallet Trezor to secure your cryptocurrencies , but you wonder if it's really reliable? The short answer is: yes, Trezor is sure , provided that you understand its safety mechanisms, its limits, and the good practices to follow. This article provides you with a detailed response.
Trezor is a range of hardware wallets (wallet hardware) designed by Satoshilabs . Today it includes several models:
These wallets are designed to store private keys offline , that is to say the information that makes it possible to sign transactions on the blockchain . Without these keys, no one can access your funds. For more details between the models, we invite you to read our detailed comparisons between the Trezor Safe 5 and the Model T as well as between Model T and Trezor One.
Yes, Trezor applies a rigorous safety approach, with several protective layers:
Unlike some competitors like Ledger , Trezor firmware is completely open source . It is published on Github and auditable by any developer. This means that there are no opaque areas in the code, and that any possible flaw can be identified and corrected quickly.
Private keys never leave the aircraft. All critical operations (generation of the SEED, transaction signature) are done inside the Wallet. Even if your computer is compromised, your funds remain intact if you only validate what you see on the screen.
Each transaction or operation is displayed on the Wallet screen. This allows you to check the address and the amount, regardless of what is displayed on the computer. A scam cannot force you to validate a transaction to a bad address without you seeing.
Upon ignition, the user must enter a PIN code to access the device. If someone tries to force the code, waiting times increase exponentially. It is also possible to add an passphrase , which acts as a second password and creates an invisible parallel portfolio for anyone who does not know it.
Ledger models SAFE 3 and SAFE 5 models now include Element Secure : a certified chip designed to withstand advanced physical attacks. It protects the SEED against extractions by electron microscopy , current analysis or laser fault injection . Associated with open source firmware, it strengthens security without sacrificing transparency. For more details between the Ledger and Trezor , we invite you to read our comparison of the Ledger and Trezor .
Model T and SAFE 5 allow the PIN code to encrypt using a microSD . Concretely, this means that without the inserted card, the device becomes unusable, even if someone knows your code. It is more physical protection.
Like any security system, a Wallet Trezor is not infallible. Here are the main risks, and how they are mixed:
If your Trezor device is lost or stolen, it does not automatically mean that your cryptocurrencies are in danger. Several mechanisms prevent a third from accessing your funds:
If you lose your recovery sentence (SEED), you definitively lose access to your funds. Trezor offers a more robust solution: the Shamir Backup .
The most frequent attacks do not target hardware, but you: false sites, false firmware, hasty confirmations or even real physical attacks. For the former, it is always necessary:
The Shamir Backup (SLIP-39) is a backup method that allows you to divide the SEED into several parts (for example 5), and to define how necessary to restore access (for example 3 of 5). You can then:
This system is only available on the Trezor Model T and SAFE 5 .
| Model | Material security | Shamir Backup | Secure Element | MicroSD card |
|---|---|---|---|---|
| Model One | Open source firmware, external screen | No | No | No |
| Model T | Open Source firmware, microSD | Yes | No | Yes |
| Safe 3 | Open Source firmware, Secure Element | No | Yes | No |
| Safe 5 | Open Source firmware, Secure Element, Microsd | Yes | Yes | Yes |
Yes, Trezor is one of the most secure systems to store your offline digital assets His conception is based on proven principles:
Security also depends on the user: do not lose your seed, never communicate it, and check each operation on the device screen. The most recent models such as SAFE 5 or SAFE 3 offer an additional layer of protective for those who want to maximize their safety.
