This rating describes our personal assessment of the user-friendliness of the product. How easy is the onboarding process? How modern is the user interface and is it easy to use? Are all the important functions quick and easy to find? We ask ourselves all these questions in order to give a personal rating from 1 to 10 points.
For products or services in the crypto space, trust and security should be the biggest factors in the selection process. Since we could not seriously evaluate the technical security of a platform or product, we analyze publicly available factors such as security features, certifications, audits, team/company, general reputation and, of course, track record.
Crypto doesn't have to be cryptic. Especially for beginners, the first contact with the crypto world can be overwhelming. With this rating, we give our assessment of how easy it is for beginners to find their way around: from the onboarding process to using the most important functions.
Customer support is an important factor for many users. A long wait or no response at all in the event of problems can be frustrating, especially when it comes to sensitive topics such as finances. With this rating, we give our assessment of the quality of customer support. In order to provide as balanced an assessment as possible, we also include user opinions from other platforms in our evaluation.
Some exchanges and brokers are regulated by financial supervisory authorities in certain countries/states. This often entails strict financial regulatory requirements and compliance requirements to which the company must adhere. Regulatory clarity can contribute to greater transparency and thus also greater trustworthiness.

A wallet that is “open source” makes its software code public (e.g. on Github). Either the entire program code or at least significant parts of it are publicly accessible. This has the advantage that many parties can review the code and security gaps or other vulnerabilities are discovered and improved more quickly.
The so-called "private key" is a unique sequence of numbers and characters and the private key that gives you direct access to and control over your cryptocurrencies. The private key is used to sign transactions. In simple terms, it can be seen as a digital fingerprint that proves that you are the owner of the cryptocurrencies. If you store your cryptocurrencies on so-called "custodial wallets" (e.g. crypto exchanges), you are not the owner of your private keys.
The anonymity of “non-custodial wallets” is generally relatively high. However, there are differences between providers when it comes to collecting and storing user data. There can also be differences in the ordering process for hardware wallets as to which user data is stored and for what period of time
The so-called “secure element” is a chip (microprocessor) that stores your private key and is separated from the rest of the hardware. This special chip gives the hardware wallet significantly more protection against local, physical attacks. Depending on the chip, a different level of security can be offered. Some chips can be compromised with less effort, while with others this is only possible with special equipment and is extremely complex.

The overall rating is the average of our individual ratings. Our ratings do not constitute investment advice, but merely our personal opinion. You are welcome to use them as rough indicators and additional perspective. In the dynamic and fast-growing crypto sector, parameters can often change from one day to the next, so we cannot guarantee that the rating data is up to date. Therefore, please never use our ratings as an isolated basis for decision-making and not as a substitute for your own research.
Some wallets offer an integrated trading function within the wallet to buy and sell cryptocurrencies directly. This functionality is usually made possible by a connection to the web interface of an exchange. The integrated trading function in wallets offers enormous advantages: cryptocurrencies can be bought in the same place where they are to be stored. The manual transfer of cryptocurrencies from an exchange to your own wallet is therefore no longer necessary, which can save time and money.
Multisignature wallets or multisig wallets are wallets that require at least two private keys to sign a transaction. This additional process makes it possible to greatly increase security against unwanted access, for example through personal threats. This security mechanism is particularly useful when storing particularly high assets.
If the hardware wallet or the device with the corresponding software wallet is lost or damaged, there is no need to panic. As long as you have your private key or recovery seed (also called “seed phrase”) in your possession, you can restore your wallet at any time. The recovery seed is a combination of 12-24 words and is the most common backup method for wallets. Important: Keep your recovery words and private keys secret and never share them with other people!
Trezor Model One: DiscontinuedDetails

The Trezor Model One is discontinued: Trezor stopped selling it in its online shop in January 2026 and offers the Trezor Safe 3 instead. If you own one, it keeps working with Trezor Suite, and Trezor plans critical security updates until at least 2036. In our view, it remains a usable wallet for Bitcoin, Ethereum and many other coins if you protect it with a strong passphrase. It does not support XRP, Solana or Cardano, and Clear Signing is not available on it. If you are choosing a wallet today, Trezor's own replacement is the Safe 3, and our Ledger vs Trezor comparison covers the current models.
Trezor Model One
Overview
Quick Facts
Trezor no longer sells the Model One and offers the Trezor Safe 3 in its place. The Model One is a small hardware wallet with a 0.96-inch monochrome screen, two buttons and a Micro USB connection, and its firmware is open source. Trezor plans basic maintenance until at least 2031 and critical security updates until at least 2036.

The Model One is simple to operate: you confirm each action with its two buttons and read the details on a 0.96-inch monochrome screen. It connects to a computer or an Android phone with a Micro USB cable. Trezor Suite works fully with it on desktop and Android, while the iOS app is limited to portfolio tracking, buying and receiving.
With Trezor Suite you can send, receive, stake and trade from the Model One. Buying, selling and swapping run through partner companies, and Trezor's terms say it charges no fee of its own for these services. You can also use it with more than 30 third-party wallet apps. Clear Signing, which shows smart contract actions in plain language on the device, is not available on the Model One; Trezor offers it on the Model T and the Safe models.
Trezor says its hardware wallets support thousands of coins and tokens, but the Model One covers fewer than its successors. Trezor's coin list shows it with Bitcoin, Ethereum, Litecoin and Dogecoin, among others, but not with XRP, Solana, Cardano, TRON or Monero, which need a Model T or a Safe model.
The Model One lacks a secure element chip. In 2019, Kraken Security Labs showed that an attacker with physical access and lab equipment could extract the encrypted wallet data from the chip in the Model One and Model T. Trezor says a strong passphrase fully mitigates this attack, and in our view it is worth setting one if you keep using the device. The firmware is open source under the GPLv3 license, and Trezor offers bug bounties up to $100,000 for critical issues. There have been data incidents involving Trezor's service providers: unauthorized access to its third-party support portal in 2024, a breach at its shipping provider ShipMonk that impacted 80,689 customers, and a breach at its newsletter provider Brevo that resulted in a phishing email being sent from Trezor's account. In the ShipMonk incident, Trezor states that its own systems remained uncompromised. Trezor also says it is uncertain whether the Model One can fully support future cryptography standards.
In our view, a beginner buying today is better served by the models Trezor sells now, starting with the Safe 3, which adds a secure element. If you already own a Model One, Trezor's support site has a guide for using a Trezor after a long time. The step that matters most stays the same: keep your wallet backup offline and never share it.
Trezor's support site offers step-by-step guides, for example on firmware updates, wallet backup and recovery, and connection problems, plus a community forum. Trezor ended its Expert onboarding and consultation sessions in mid-2026.
In our view, the Model One still does its job for owners who use it for Bitcoin and Ethereum and protect it with a strong passphrase. For a new purchase we would look at its successors: our Ledger vs Trezor comparison covers the Safe 3, Safe 5 and Safe 7. Our Trezor Model T review covers the other discontinued Trezor, our Ledger Nano S Plus review a current alternative from Ledger, and our wallet overview every wallet we review.
