Hardware Wallets are popular nowadays. With the boost of Bitcoins and other cryptocurrencies, it is a challenge for the owners to protect their Bitcoins. There are lots of choices to keep your Bitcoins secure, and Ledger Nano is one of them.


Founded in 2014 in France, a Ledger Nano is a hardware wallet for Bitcoin, Ethereum, and different Altcoins. It is a cryptocurrency hardware wallet that allows you to store your Bitcoins and another cryptocurrency safely. It might be small that looks like a normal USB device but it can bring huge protection to your coins. Ledger Nano allows you to conveniently make transactions like receiving and sending payments on any computer quickly and securely. Other than that, it can be used for storing your digital assets with high-level security.


Owning cryptocurrencies makes you worried, especially for the security and access to your funds. Protecting your confidential data and keeping your coins safe is a challenge for most of the coin owners. With the Ledger Nano, your information and coins will be protected inside an isolated device locked with a PIN code. This will protect your transactions from being altered and keeping your coins away from hackers and risky online storage servers.


The design is simple, small, and sleek. Because it’s small, you can bring it anywhere. The hardware wallet is manufactured in metallic cases that bring protection to the possible physical harm. You will not be worried if you ever accidentally dropped the device.

Using the wallet

Ledger wallet has a similar method of usage in general among hardware wallets on the market. The standard process is quite straight-forward. Once, the hardware wallet is set-up for the 1st time, users usually are asked to provide the preferred secure PIN. Later on, a 24-word seed will provide which required for the creation of the private keys. Let me discuss further on how to use the Leger wallet efficiently.


Once the Installation completed: the leger wallet device will merely be inserted into a USB port on your machine (PC/laptop) and enter the PIN that you recently created to access the wallet interface. The wallet “user interface” is pretty user-friendly, that anyone especially those who are familiar with bitcoin wallets should feel at home. The only difference is on the security level, where they had added a feature of validation with the security card that required for all transactions.


How does the security card work? The wallet will provide simple instructions for the user to follow and enter the “four-character code” to validate the transaction. The security card obtains the corresponding characters that need to enter for the validation process.


Besides on the “security card validation”, it also has the features of QR scanner that is very helpful when you simulate topping up a mobile wallet. It could be a time saver in some situations.


Sending/Receiving BTC

Initialized the ledger wallet device by inserting into the dedicated computer and launch the Ledger Wallet Bitcoin Chrome application or just follow these simple steps below:

Step 1: Connect your Ledger device

Step 2: Enter your PIN code

Step 3: Open the Bitcoin app on your Nano S (right click)

Step 4: Launch your Bitcoin Chrome application on your computer

Step 5: Click on “Send/Receive, “and a pop-up window opens.

5.1: Sending: Fill in the required fields such as “amount and recipient address (you can able to paste or scan),” and click on the “Send”button. Then, it will authenticate the physical device.

5.1.1: Click the right button to confirm and wait for the “Chrome app” displays “validated.”

5.2: Receiving: Simply copy and paste the “Bitcoin address” into the receiving wallet, and wait for confirmation.



Different coins and other confidential data can be easily hacked and tempered when stored online. Using a hardware wallet like Ledger Nano allows you to store your coins in a secure offline environment so it will be away and out of reach from the hackers.


The vault storage is protected by a 4-digit PIN code and if ever your device is lost or stolen, you will not be too much worried because, after three wrong guesses for the PIN code, the device will shut down and wipe itself.
