Frequently Asked Questions
I want to know more about Ledger
Ledger enables secure blockchain applications for enterprises, industrials and consumers. We provide endpoint security solutions for PCs, smartphones, servers and IoT devices. We are a French startup with offices in Paris, Vierzon and San Francisco.
Where are the products made?
All Ledger's products are designed and assembled in France and Asia . We have our own assembly lines located in the center of France ( Vierzon ). We favour local suppliers when possible (injection molding, metal works...).
Is Ledger somehow like a bank?
Absolutely not. If the functional usage of the Ledger Wallet can be seen as a banking application, there is one major difference : Ledger never holds any of your crypto-currencies. The Ledger Wallet is just software built on a piece of hardware. Therefore Ledger is not at all subject to any kind of financial regulation. We are not in any case custodian of your assets.
Can Ledger have access to my bitcoins?
Absolutely not. Ledger will never have any knowledge of your master seed, private or public. Wallets are sold empty, and an initialization process is required to be done by the user to generate the private keys. This process is done locally and will not send any information to our servers. The Chrome application is open source .
What is your privacy/tracking policy?
All wallets are sold with identical firmware, without any serial or tracking information. It is therefore not possible to link your wallet to your shipping address. We cannot, and we absolutely do not want to track any of our customers.
We do not keep nor archive any log of our APIs regarding the use of our wallet applications; All logs used for debuging purpose (sent by users) are destroyed after analysis.
Why are hardware wallets more secure?
If you are not familiar with the notion of hardware wallets, you may wonder what would be the advantages versus a paper wallet or an encrypted private key on a computer.
The main principle behind hardware wallets is to provide a full isolation between the cryptographic secrets (private keys) and your easy to hack computer or smartphone. Vulnerabilies of modern PCs and smartphones are well known, and if you keep your private keys there (private key = your bitcoins ) it’s just a matter of time before you’ll get hacked and lose everything.
A paper wallet may be secure, but only until you want to use your funds, requiring importing your private keys on your computer. And if you think a password encrypting your keys is enough, malwares are smart enough to wait for the inevitable decryption before sweeping your funds.
Hardware wallets are convenient, affordabe , portable and backuped by a paper wallet allowing an easy recovery in case of loss. If you have any significant amount of bitcoins , using a hardware wallet should be a no brainer.
Why Ledger hardware wallets are even more secure?
Ledger's hardware wallets are architectured around "secure elements" or secure chips. This is the same technology that find in chip and PIN payment cards or SIM cards. These chips bring guarantees against physical attacks and raise the level of security of your private keys.
We come from the security industry ( Gemalto , Oberthur ...) and we have extensive experience in the field of smartcards and secure embedded OS.
What do I need to use Ledger's hardware wallets?
a computer with an USB port (for Nano S, Nano, HW1)
Google Chrome or Chromium 50+
Windows (not XP), Mac (10.7+) or Linux.
The wallet interfaces with the computer through a Chrome application which you will need to install on your computer. No additional software installation or account creation is needed.
What are the differences with other hardware wallet vendors?
Other hardware wallets do not rely on smartcards and are based on regular microcontrollers. This leads to possible security holes such as side channel attacks, private keys leaks through code exploits and physical key extraction as soon as it is stolen.
What are the differences with cold storage?
Cold storage (such as a paper wallet in a physical safe) can be a very effective solution to secure your bitcoins . The benefit of Ledger Wallet is that it keeps the same level of security but adds convenience. Indeed, cold storage prevents by definition all usage of your bitcoins . As soon as you need to spend them, you'll have to import your private keys on your computer, and you'll have the same security problem if it has been compromised.
What are the differences with software wallets?
The difference, apart from interfaces and functionalities, is that even if your private keys may be stored encrypted on your computer (or cloud service), they must be available in plain text in your computer memory whenever you sign transactions. When your computer is compromised by specialized Bitcoin-targetting malware (and it is just a matter of time), it will be extremely easy for the malware to steal your bitcoins.
What are the differences with vaults or centralized solutions?
Centralized services host your bitcoins . They solve the above-mentioned security issue by assuming total responsibility for security. You give up direct control of your bitcoins in exchange of third-party supplied security, just like you trust a bank for keeping your dollars or euros. It is a very convenient approach, but which needs an alternative possibility for users who wish to retain full control of their assets.
Do I need to open an account with you or pay any subscription?
No. There is no subscription plan or account to be created.
Can I use a hardware wallet as a direct payout from a mining pool or a faucet?
It is not recommended to receive small payments (also called dust payments) on a hardware wallet. This kind of incoming payments are typical of mining pools or faucets.
Set the payment threshold at a higher level (for instance 0.05 BTC), or use a temporary software based wallet which you'll empty every 0.05 BTC.
The reason is that the chip must sign all inputs when you want to make an outgoing transaction. Imagine that you have received 1,000 payments of 0.001 BTC. If you want to make a payment of 1 BTC then the chip will have to construct a transaction of 1,000 inputs and sign 1,000 times. Not only it will take a few hours, but you have risks that it will not manage to do it (the chip may get too hot and fault some computation etc).
If you are already in this case, the best is to restore your 24 words seed on Multibit HD or Mycelium and empty your wallet (and stop receiving dust payments).
Is my hardware wallet nominative? Can I resell it or give it to someone else?
You can give or offer any of our products, as they are all strictly identical and "anonymous". All devices can be reset by submitting a wrong PIN three times . It is therefore easy to resell it in its initial empty state.
Are my coins stored on my Ledger?
Your coins are not on the device itself, they are tracked on the Blockchain . Your Ledger hardware holds and protects the private data useful to access and manage them. These data (private keys) are the certificate of ownership of your coins: they give full access to these coins.
That is why the 24 words you have copied to your recovery sheet when you initialized your device are paramount: they are the backup passphrase to import these access data in any wallet, they give full access to your coins.
But without these 24 words and without your PIN code, not anyone can access your wallet, even if your Ledger device gets stolen. Your secrets are securely stored inside the Secure Element of your device, your coins are safe.
Must my Ledger be connected when I receive coins?
Your coins are not on the device itself, they are tracked on the Blockchain . Your Ledger device holds and protects the private data useful to access and manage them. These data (private keys) are the certificate of ownership of your coins: they give full access to these coins. When you want to receive coins, you just have to provide your address to the payer. Your Ledger device doesn't need to be connected as the transaction is made on the blockchain, not on the device itself. Next time you connect your wallet, it will synchronize to the blokchain to display all your past operations and your balance.
How can I backup my Ledger wallet?
You don't have to make any added manipulation to backup your wallets: you already have an operational backup as soon as you initialized your device.
The 24 words you copied on your Recovery sheet when you first handled your device is your backup. These 24 words are your " seed ", which is like a passphrase that generates all your public and private addresses.
When you need to import your accounts in another compatible wallet, you must enter these 24 words in the new wallet, it will automatically synchronize all your transactions from the blockchain and shows your correct balance.
