First, let’s briefly review basic information about Ledger and Trezor.

What is Ledger?

Ledger Wallet

Ledger is a USB bitcoin wallet that combines smart card security and encryption technology to secure your cryptocurrency’s private keys. The Ledger wallet company is based in France and has sold over 1.5 million hardware wallets since its corporation.

Ledger launched its flagship product (simply called Ledger Wallet Nano) in December 2014. The company was going on to release improved versions such as the Ledger Nano S and the Ledger Nano X devices.

The Ledger wallet’s core features include the Ledger Live app, which lets users manage coins and tokens stored on the app, and a unique operating system (BOLOS), which protects it from hackers.

What is Trezor?

Trezor Wallet

Trezor was the first bitcoin hardware wallet available to crypto users. It was developed by a Czech-based security company, Satoshi Labs. The company’s flagship product, now known as the Trezor One, was released in January 2014 and preceded the next-generation device, the Trezor Model T launched in February 2018.

Unlike Ledger, Trezor devices are shaped like mini-smartphones with a smaller screen. Core features include protected key operations, firmware verification, a secure update procedure, and an intuitive interface.

Ledger Nano S: The device has an OLED screen with adjustable brightness functionality for users. The display size is 128x32 and is just enough to display setup instructions and other on-screen information.


Trezor One: You can take the following steps to set up a Trezor One after confirming that it comes with a tamper-proof seal upon delivery:

  • Connect the device with the USB cord that comes with it.
  • Visit trezor.io/start in your web browser.
  • Pick the Trezor One as your device and then Download and Install the Trezor Bridge (also available on this link, https://wallet.trezor.io/#/bridge).
  • As soon as the bridge recognizes your device, Select “Install Firmware” and patiently wait for the process to complete.
  • Select “Create New Wallet” by pressing the right button after the firmware installation is complete.
  • Backup your seed phrase and confirm.
  • Create a PIN code and complete setup.
  • The Trezor.io web interface is used to initiate send or receive transactions that you’ll then confirm on the hardware device.

Ledger Nano S: To set up a Ledger Nano S device, take the following steps:

  • Download and Install the Ledger Live app to your computer from Ledger.com/live.
  • Launch the app, and select your preferred display mode.
  • Select Initialize as a new device and select the Ledger Nano S on the next screen.
  • To Set up a PIN Code, use the left and right buttons on the hardware device to navigate to “Setup as New Device.”
  • Press both buttons to choose your PIN code.
  • Use the right and left buttons to select digits and both to validate.
  • Press both buttons to confirm and re-enter them on the next screen.
  • Press Continue on the web interface and proceed to seed phrase backup.
  • Write down the seed phrase on the provided sheet and confirm.
  • Complete the security checklist on Ledger Live and finish the setup process.


Trezor One: The Trezor One is mobile and usable because of its small size that can fit into most physical wallets. The developers include advanced security features such as the Shamir Backup but primarily supports simple, user-friendly add-ons such as wallet labeling and estimated transaction fees.

Anyone with basic knowledge of Bitcoin can use the Trezor wallet with little or no extra guidance required.

Ledger Nano S: Aside from a little frustrating setup process that is rightly so for security reasons, the Ledger Nano S is suitable for day-to-day use.

Texts on the supposedly small screen are displayed large enough for anyone to read, and the menu is easy to navigate. The device is also easy to carry around, just like any typical USB device, with the metal screen cover being an extra edge that protects it from being wrecked by keys in your pocket or bag.

Supported Devices

Trezor One: The device is compatible with both phones (Android and iOS) and desktop computers (Windows, macOS, and Linux). Windows must be version 10 or higher, and macOS also has to be version 10.11 or higher.

Ledger Nano S: The Ledger Live app, which works with the Ledger Nano S, is compatible with any modern Android (Android 7+) phone using a USB cable. For iOS users, the app is available for iOS 9+ devices in consultation mode that allows holders to track their assets’ current market value.

Additionally, you can use a USB cable to connect your Ledger Nano S to desktop devices with the following specifications, Windows 8+, macOS 10.10+, and Linux.


Trezor One: Trezor is an open-source project, meaning that its software code is fully auditable and contains no backdoors for hackers. Other security layers include the generation of a 24-word seed phrase, PIN, passphrase, the Trezor password manager, and Shamir Backup.

After every unsuccessful attempt to insert your PIN, Trezor enforces a delay period before you can try a different PIN. After 16 unsuccessful attempts, the device wipes itself, meaning you can only access your funds via the recovery phrase. This makes it unable for hackers to brute-force their way into your wallet.

Another common way cryptocurrency holders lose funds is by malware transferring funds to an address different from the one copied on your clipboard. Trezor has a tool that warns users when they attempt to confirm such transactions on their device.

Ledger Nano S: Its use of a smartcard chip cryptographically verifies the Ledger Nano S integrity.

Other security layers include users’ ability to set up 2 PINs, one for confirming daily transactions and another for cold storage, and as a complementary backup key alongside the 24-word seed phrase.

After three unsuccessful pin attempts, the device erases itself, offering slightly higher protection if an intruder gains access to the device.

The main differences

While Ledger Nano vs Trezor is available at almost the same price and offers virtually the same level of hardware security, here are some key differences you need to know:

  • The Trezor One has twice the screen size of the Ledger Nano S. Their screen pixels size is 128x64 and 128x32, respectfully.
  • The Ledger Nano S supports most large-cap crypto assets not available on the Trezor One. As noted earlier, these include Ripple (XRP), Cardano (ADA), Monero (XMR), Tezos (XTZ), EOS (EOS), and Ontology (ONT).
  • The Ledger Nano S is made of stainless steel casing, making it more durable than the Trezor One, made of plastic.
  • The Trezor One erases your private key after 16 unsuccessful PIN attempts. The Ledger Nano S lowers this threshold to just 3, which is arguably more secure.
  • You need a Windows desktop up to version 10 to use Trezor One. Ledger Nano S supports Windows 8+ devices.
  • The Trezor project is completely open-source. Ledger isn’t fully open-source.

Why should you choose a hardware wallet?

Anyone who holds large amounts of crypto must consider a hardware wallet for the following reasons:

  • Hardware wallets keep assets completely offline and less susceptible to theft.
  • There are no verifiable stories about hardware wallets being directly compromised.
  • These devices are immune to malware and viruses that otherwise plague hot wallets.
  • Combining the power of hardware wallets with the censorship-resistant nature of cryptocurrency allows large amounts of value to be moved across-borders securely.
  • Since transactions are verifiable only on the device, you are completely in control of your funds.
  • Funds are easily recoverable in the event of physical damage to the device.
  • Using decentralized exchanges like Uniswap, you can secure trade your crypto assets without giving up its control to a centralized party.

Physical Wallet Security Tips

  • When you buy a new device, ensure that it comes with a secure tamper-proof seal.
  • Since supply chain attacks are common for hardware wallets, we recommend that you don’t purchase fairly-used devices.
  • Never attempt to break into or open the device forcefully.
  • Always keep your device away from prying eyes when not in use and also when you send transactions. Do not use it in a public place.
  • Do not expose the device to extreme temperatures, fire, or humidity.
  • While your backup seed phrase is usually to be written down on paper, you can use metal plates to engrave your seed phrase. This way, it will be more immune to fire outbreaks, water, and other forms of physical damage.

Ledger Vs Trezor: Final thoughts

The Trezor One and the Ledger Nano S are very close competitors, making it difficult to declare one an outright winner.

If we must, however, then you should know that the Ledger device is well ahead of the Trezor when it comes to size, durability, number of supported assets, and pricing. The Trezor is more suitable if you’re concerned with security and ease-of-use (because of add-ons and screen size).

While there are several reports of Ledger users being victims of email and SMS phishing attacks, Trezor is ahead in protecting user information provided during the purchase.


Given the third-party risks associated with using custodial wallets and exchanges, Hardware wallets provide a suitable and secure alternative for cryptocurrency holders to keep their funds entirely offline.

The Trezor One vs. Ledger Nano S are the lowest-priced high-grade hardware wallets in the market right now and a good entry point if you’re want to start using one. If you have a larger budget, you may want to check either the premium Ledger Nano X or the Trezor Model T.

We hope that the information shared in this review article will allow you to choose from the duo as you get on the path to keeping your crypto as far as possible from hackers.
