woulda been nice if it came with how to instructions, i cant even get mine going , not impressed
This is my comment after using the Ledger Blue which I fell in love within seconds.
Typography is light gray which is hard to read, even for young eyes. Also to small. The “Auto lock delay” and the “Power off delay” buttons are far to light in color and the letter in the buttons have no contrast what makes it hard to read. The keyboard could be bigger as the screen has enough space. The button “Continue” is to light and also hard to read.
The Authenticate Button should be in the first place. Logically.
With cryptocurrency the user are confronted with new technology which a user has problems to grasp. A clear typo and bigger letters would help to ease the eyes and the mind and help to concentrate on using the applications. DON’T Forget, the users are retired people and teenagers, actually the whole range of any age, starting with four years. Eyesight is declining through the use of small screens like mobile phones and working on computer screens.
Ledger Blue is still far superior tho the Trezor which typo is horrendously small. Readable only with a magnifying glass. Mine sleeps in a drawer on the bottom of a kitchen counter.
A riddle is the back of the device. What do the letter say?
As a product designer educated in Switzerland I can tell that Ledger believes the screen design has to be elegant. Look at a manual from an air plane or of a stealth bomber, a sniper gun or just a love letter. You want them to be read and understood. Especially a writer of love letter wants to be rewarded with some sweet kisses. Repeatedly. A great designer brings the writings to life and makes it readable.
Ask your female staff about it. Their answers and comments have great value.
I am very sorry to write this. It needs a voice which sees the potential of the product.
Thank you for the ease of use with the excellent hardware!

Agreed. I find it amazing they can put out such an enterprise product with such a badly designed UI – did they ever try it? EXTREMELY small grey font on white. Impossible to read. Ok, I ear glasses and am 50 – but I haven o problem using my phone. Somehow on my phone they manage to make the text larger and with proper contrast.
This is getting comical if you look at WHAT they communicate. Most of the time, you basically stare at an empty screen. Because settings has one line (text like 30% left, then a button on the right). NO reason they could not make better sizes. BOLD font and maybe light grey is not exactly smart on a white screen.
The concept is amazing – the execution prefers good looks over usability. This is not enterprise ready – it is “amateur hour” in the design area.
thanks for your comments ; I will postpone my buy until those problems are resolved !
FAQ 7
Ask your own questionI lost my hardware wallet. Now what?
That is not a problem. You can restore your accounts to a new hardware wallet using the recovery key you wrote down when you set it up.
Is it possible to restore all cryptocurrencies with a hardware wallet backup?
Most wallets support more than just one cryptocurrency, but only generate one backup. Nevertheless, this one backup is sufficient to restore all cryptocurrencies as all private keys of the different wallets result from the seed that is backed up as a backup during setup.
How does a hardware wallet work?
Hardware Wallets such as the Ledger Nano X, TREZOR Model T, BitBox02 or KeepKey all work according to the same principle. They are a special form of a so-called wallet, which is used to manage cryptocurrencies. A hardware wallet is a physical device that securely and inisolationly generates the private keys to the cryptocurrencies. Due to the extra hardware, they have some advantages over software wallets:
However, it is important to understand that hardware wallets are an attractive target for attackers and depend on several assumptions to maintain security. They are not a miracle weapon, and there are several realistic ways to hack a hardware wallet Especially if someone has physical access to the device.
What happens if there are new cryptocurrencies – do I need a new hardware wallet?
A new cryptocurrency is rarely supported directly by a hardware wallet at the beginning. However, most providers such as Ledger or TREZOR are constantly working to support new cryptocurrencies. Therefore, it is often worth waiting until the desired currency is supported by your hardware wallet.
I would like to give a hardware wallet as a birth gift. Do I need this every time I want to deposit coins or is there another way?
No, you don’t need the hardware wallet every time you want to make a deposit. It is only necessary to set up the hardware wallet and generate an address of the corresponding cryptocurrency.
Cryptocurrency can now be sent to this address on the desired cycle on a regular basis without the need for the hardware wallet. The address does not expire.
Hardware wallets: Where are my cryptocurrencies actually stored?
Are my cryptocurrencies stored in the hardware wallet, or where exactly are they? This is a very good question because the answer defines what your wallet actually needs to protect.
Cryptocurrencies are so named because they are secured by cryptography. For this you need a set of digital keys, for example your (very secret) private key. With this key you can encrypt and digitally sign things.
Let’s take Bitcoin as an example (other cryptocurrencies work in a similar way). The entire Bitcoin network is kept up to date by a common data structure called the blockchain. It contains records of all transactions ever made and is publicly accessible online, so anyone can read it. When you receive some bitcoins, say 0.1 BTC, you see them in your bitcoin wallet, listed under a bitcoin address.
At the same time, the bitcoins are not actually stored in the wallet, they are just an entry in the public blockchain. What the wallet stores is your secret private key that belongs to that address. Since you control that private key, you can spend those Bitcoins again: that’s how “Bitcoin ownership” is defined. Anyone can see these bitcoins, but only you can spend it, so they are yours. But that also means that *anyone* with the right private key can spend those bitcoins. Therefore, it is very important to keep this key secret.
What stops the hardware wallet manufacturer from stealing my cryptocurrencies?
What stops the manufacturer of your hardware from using a backdoor and simply stealing your cryptocurrencies? How much do you have to trust hardware wallet manufacturers?
While a completely “trustless” solution is probably not possible, manufacturers are doing everything they can to minimize the need to trust them.
Most of the software code of many hardware waller manufacturers is open source, i.e. publicly available. Anyone can check how the device works and how secrets are handled. Of course, not everyone has the ability to review code: that’s why independent researchers are often encouraged to analyze, and are often rewarded by bug bounty programs when they find something. This does not limit their ability to publish a full independent report without permission.
The essentials to go: A wallet manages your secret private keys and requires full access to them. You can and should demand full transparency about how a wallet works and ensure that independent public audits are encouraged.
