Hardware Wallet and Bluetooth: A Match?
The Ledger Nano X's Bluetooth feature has made waves in the crypto community, but it's also sparked concerns about security.
The Bluetooth capability can open up a greater number of attack vectors, according to critics.
A recent vulnerability discovered by Wallet.fail at the Chaos Communications Conference (35C3) in December 2018 showed how hackers could sign transactions remotely after infecting a victim's computer with malware.
The Ledger and Trezor teams quickly announced incoming patches for their software, claiming the vulnerability to be resolved.

The private keys on the Ledger Nano X never leave the secure chip, so Bluetooth communication doesn't expose the wallet to any additional security threats.
The BLE connection is end-to-end encrypted to protect user privacy, and in the unlikely case the BLE transport were to be compromised, an attacker would never be able to extract private keys or make users sign a transaction they don't wish to sign.
The ability to connect a hardware wallet with a smartphone application is a growing trend in the industry, and the Ledger Nano X is a prime example of this shift towards greater usability.
The device's larger memory capacity allows for a larger number of token-specific apps to interact, with up to 100 secure applications and 1,100 cryptocurrencies supported.
The Ledger Nano X will be available for pre-order at $139, with items shipping in March 2019.

- Software: Wallet applications on devices that store private keys
- Paper: Keys written or typed on a piece of paper
Types of Wallets
There are three main categories of cryptocurrency wallets: hardware, software, and paper. Hardware wallets store your private keys on a physical device, making them a secure option.
Hardware wallets can be further classified into hot and cold wallets. Hot wallets have an active internet connection, while cold wallets do not.
Software wallets, on the other hand, are applications that run on personal devices, such as computers, laptops, and mobile devices. They store your private keys and provide a user-friendly interface.
Paper wallets are a simple way to store your private keys, but they can be easily damaged and lost.
Here's a breakdown of the different types of wallets:
Within the hardware and software categories, wallets can be further classified as hot or cold. Hot wallets have an active internet connection, while cold wallets do not. Custodial wallets store your keys for you, while non-custodial wallets give you control over your keys.
Wallets Work
Ledger offers a range of cold, non-custodial hardware wallets that store private keys offline on a secure hardware device.
These wallets are device-based, using storage mechanisms like USB drives to store private keys, making it difficult for hackers to access them from an online location.
The company offers four different hardware wallets: the Ledger Flex, the Ledger Nano S Plus, the Ledger Nano X, and the Ledger Stax.
Each of these wallets works with the Ledger Live app, which the owner uses to access the keys and purchase and manage their crypto.
All transactions executed must be authorized by the user, adding an extra layer of security.
Ledger's storage wallets let you perform various functions, including sending and receiving cryptocurrency and using two-factor authentication (2FA) applications.
All Ledger products combine a Secure Element and a proprietary operating system designed specifically to protect a user's cryptocurrency assets.
A 24-word, 96-character backup recovery phrase is generated to access your cryptocurrencies if the device is lost or stolen.
For the extra-cautious, the 24-word phrase can be etched into steel in a Billfodl, which holds seed phrases or keys in a sturdy physical form.
Here's a brief overview of Ledger's hardware wallets:
These wallets support more than 5,500 coins and NFTs, making them a great option for cryptocurrency enthusiasts.
The Ledger Stax, in particular, is a portable storage device that's small enough to fit into the palm of your hand.

Setup and Configuration
Creating a custom key management setup is an option if you need more flexibility, but it's the most time-consuming approach.
You'll need to consider procedures for handling private keys, manually creating transactions, and tracking confirmations, as outlined in the key management guide.
To manage accounts, you must first create a wallet to hold the seed or private keys for the accounts.

Custom Key Management
Custom Key Management is a crucial aspect of securing your cryptocurrencies. You can create your own custom key management setup if none of the third-party offerings work for your integration needs. This is the most time-consuming option, but it's also the most flexible.
The key management guide is a valuable resource for handling private keys, manually creating transactions, and properly tracking confirmations. It's essential to follow the guide carefully to ensure the security of your assets.
You can create a wallet to hold the seed or private keys for your accounts using various commands. For example, if you started the node from the published binary builds or Docker images, a wallet will have already been created. However, if you're self-building a node, you'll need to use commands to create the wallet and seed.
To replace the wallet's automatically generated seed with your own, you can use the wallet_change_seed RPC command. This command replaces the existing seed and clears all deterministic accounts in the wallet, so be sure to backup the old seed first if necessary.
Here are some key considerations for custom key management:
- Private keys should be stored offline to prevent hacking.
- A secure hardware device, such as a Ledger Nano X, can store private keys.
- A 24-word, 96-character backup recovery phrase is essential for accessing your cryptocurrencies.
- The recovery phrase should be stored in a safe place, such as a Billfodl.
Set Password
Setting a password for your wallet is a crucial step in securing your funds. It's best to change from the empty default to a secure password using the 'password_change' RPC.
This will ensure that your wallet is protected from unauthorized access.
Node
The node wallet is included in published binary builds and Docker images, and it runs alongside nano_node by default.
To use the node wallet, you'll need to review the QT wallet section of the build guide if you're building the node manually. The node wallet is not supported for use in production environments.
A basic walkthrough on how to set up a wallet and make a transaction using the built-in node wallet is available. This guide assumes you understand the differences between accounts, private and public keys, seeds, and wallet IDs.
Creating a wallet with a seed and generating accounts from that seed will be the focus of this walkthrough.
