Ledger Flex vs Trezor Model One: Overview
The Ledger Flex and Trezor Model One are both hardware wallets designed to securely store cryptocurrency private keys offline. Ledger, a French company founded in 2014, launched the Flex in July 2024 as their latest offering. The Trezor Model One, on the other hand, was unveiled in February 2018 by SatoshiLabs, a Czech Republic-based company established in 2013.
These devices represent different generations of hardware wallet technology. The Ledger Flex is a more recent product with modern features like a touchscreen and wireless connectivity, while the Trezor Model One is a well-established, budget-friendly option known for its simplicity and open-source design.
Both wallets aim to provide a secure solution for cryptocurrency storage, but they differ significantly in their approach, features, and target users.
Design and Build
When it comes to looks and feel, these two wallets couldn’t be more different. Let’s break it down:
Feature |
Ledger Flex |
Trezor Model One |
---|---|---|
Screen |
E Ink touchscreen (2.84 inch) |
Small OLED display (0.96 inch) |
Body |
Aluminum frame, plastic back |
All plastic |
Controls |
Touchscreen |
Two buttons |
Size |
78.4 x 56.5 x 7.7 mm |
60 x 30 x 6 mm |
Weight |
57.5g |
12g |
My take: The Ledger Flex feels like a premium product with its sleek design and touchscreen. It’s bigger and heavier, but that E Ink screen is a game-changer for readability. The Trezor Model One is more basic and plastic-y, but it’s super lightweight and pocketable. If you want something that feels high-end, go for the Flex. If you prefer a no-frills, ultra-portable option, the Trezor is your best bet.
Security Features
Both wallets take your crypto’s safety seriously, but they approach it differently:
Feature |
Ledger Flex |
Trezor Model One |
---|---|---|
Chip |
Secure Element (CC EAL6+ certified) |
General-purpose microcontroller |
Software |
Closed-source Ledger OS |
Open-source |
Protection |
PIN code |
PIN code + optional passphrase |
Extra |
Clear Signing feature |
Shamir Backup (advanced recovery) |
My opinion: Security-wise, both are solid choices. The Ledger Flex’s certified chip gives me peace of mind, and that Clear Signing feature is neat for double-checking transactions. But I really dig Trezor’s open-source approach – it means anyone can check the code for issues. The passphrase feature on the Trezor is also a nice touch for the extra paranoid (like me). If you’re big on certified hardware, lean towards the Flex. If you love open-source and want more DIY security options, the Trezor Model One is calling your name.
Supported Cryptocurrencies
Here’s the quick rundown on what you can store:
Wallet |
Supported Cryptocurrencies |
---|---|
Ledger Flex |
5,500+ coins and tokens |
Trezor Model One |
9,000+ cryptocurrencies |
What I think: At first glance, the Trezor Model One is the clear winner with way more supported coins. But here’s the thing – unless you’re deep into obscure altcoins, both wallets will likely cover all your bases. The Ledger Flex supports all the major players and then some. Plus, it has built-in NFT support, which is pretty cool if you’re into digital collectibles.
My advice? Don’t let the numbers alone sway you. Check if the specific coins you own or plan to buy are supported. For most folks, either wallet will do the job just fine. If you’re an altcoin enthusiast or want to future-proof for some really niche tokens, the Trezor might edge out. But for the average crypto user, the Ledger Flex’s lineup is more than enough.
User Interface and Experience
The way you interact with your wallet can make a big difference in day-to-day use. Let’s see how these two stack up:
Feature |
Ledger Flex |
Trezor Model One |
---|---|---|
Screen |
Large E Ink touchscreen |
Small OLED display |
Controls |
Touch-based |
Two physical buttons |
Transaction Signing |
Clear Signing on screen |
Verify on device screen |
Ease of Use |
Smartphone-like |
More basic, but simple |
My take: I’ve got to hand it to the Ledger Flex here. That big E Ink touchscreen is a game-changer. It’s like using a mini smartphone, which most of us are already comfortable with. The Clear Signing feature is super handy – I can actually read and understand what I’m approving.
The Trezor Model One, with its two-button system, feels a bit old-school in comparison. It’s simple and gets the job done, but it can be a bit fiddly, especially with long addresses.
If you want a smooth, modern experience, the Flex is the way to go. But if you prefer a no-frills, straightforward approach (or have fat fingers that struggle with touchscreens), the Trezor might be more your speed.

Connectivity Options
How you connect your wallet can impact its convenience and versatility. Here’s what each offers:
Feature |
Ledger Flex |
Trezor Model One |
---|---|---|
Wired Connection |
USB-C |
Micro USB |
Wireless |
Bluetooth 5.2 |
None |
Mobile Compatibility |
Yes (iOS & Android) |
Limited |
What I think: The Ledger Flex is living in 2024, while the Trezor Model One is stuck in 2015. The Flex’s USB-C is the current standard, and having Bluetooth is super convenient for quick mobile transactions.
The Trezor’s Micro USB feels dated. It works, but finding a cable can be a pain these days.
If you’re always on the go and love managing your crypto on your phone, the Flex is a no-brainer. The Bluetooth feature is a massive plus. But if you’re more of a desktop user and don’t mind being tethered, the Trezor will serve you just fine. Just don’t lose that Micro USB cable!
Software and Ecosystem
The software you use with your hardware wallet can make or break your experience. Let’s see what each offers:
Feature |
Ledger Flex |
Trezor Model One |
---|---|---|
Main Software |
Ledger Live |
Trezor Suite |
User Interface |
Modern, app-like |
Clean, straightforward |
Features |
Buy, sell, swap, stake |
Basic management, exchanges |
Third-party Support |
Wide range |
Extensive |
My opinion: Both Ledger Live and Trezor Suite are solid pieces of software, but they cater to different users.
You can do pretty much everything without leaving the Ledger Live app – buy, sell, swap, and even stake your coins. It’s great if you want an all-in-one solution.
Trezor Suite is more stripped-down but still powerful. It’s straightforward and gets the job done without any fuss. I appreciate its clean interface and focus on security.
Both play nice with various third-party wallets, so you’re not locked into their ecosystems.
If you want a feature-rich, do-it-all app, Ledger Live wins. But if you prefer a no-nonsense, security-focused approach, Trezor Suite might be more your style. Personally, I lean towards Ledger Live for its versatility, but I can see the appeal of Trezor’s simpler approach, especially for beginners or security purists.
Additional Features
Both wallets pack some extra goodies that might sway your decision. Let’s check them out:
Feature |
Ledger Flex |
Trezor Model One |
---|---|---|
NFT Support |
Yes, built-in |

Basic OLED |
Battery |

No battery (USB powered) |
Extra Security |
Clear Signing |
Two-factor authentication |
Privacy |
Standard |
Coin control feature |
My take: The Ledger Flex feels like it’s got one foot in the future with its NFT support and that cool customizable E Ink display. I love being able to show off my favorite NFT even when the device is off – it’s a neat party trick! The battery life is a big plus for me too, especially when I’m traveling.

The Trezor Model One keeps it old-school but has some tricks up its sleeve. That coin control feature is a godsend for privacy nuts like me. And the two-factor authentication adds an extra layer of security that I really appreciate.
If you’re into NFTs and like a bit of flash, the Flex is your jam. But if you’re all about that extra privacy and don’t mind a more basic look, the Trezor might be calling your name.
Compatibility

Not for mining |
What I think: The Ledger Flex is a champ when it comes to playing nice with your devices. It’s got solid support for all major desktop operating systems and full-fledged mobile apps. I love being able to manage my crypto on the go with my phone.
The Trezor Model One is a bit more limited on the mobile front, but it makes up for it with broader desktop support, including Chrome OS. If you’re a Chromebook user, this might be a deciding factor for you.
Neither of these is meant for mining, so keep that in mind if you’re looking to dig for digital gold.
For me, the mobile support of the Flex is a big win. But if you’re mostly a desktop user and want that Chrome OS compatibility, the Trezor might be the better choice.
