 Heavy users of the lightning network, such as routing node operators, often run lightning nodes on dedicated hardware. Lightning nodes require 24/7 uptime, which is much easier to achieve with dedicated hardware. Lightning nodes also require the private keys to be stored on the same device. Dedicated hardware reduces the attack surface and makes it easier to secure private keys.
 
-[Plug-and-play hardware nodes](https://samouraiwallet.com/nodl) exist and make it simple to set up a dedicated hardware node. The most common way people run dedicated hardware nodes is installing a node OS, like [Umbrel](https://getumbrel.com/) or [MyNode](https://mynodebtc.com/), on a hardware device.

-The controlling keypair of a bitcoin wallet can be derived from a *recovery phrase* of 12 words (it can also be 18 or 24 words, which is less common and not recommended as it does not provide better security) from a standardized list, defined in [BIP39](https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki). [Learn here](https://bennet.org/blog/how-secure-is-your-bitcoin-wallets-mnemonic-seed-phrase/) how the words are chosen. The recovery phrase provides full access to a bitcoin wallet as it contains the private key and is therefore very valuable. It’s extremely important to keep it safe, both from other people getting access to it and for yourself not to lose it by creating one or several backups of the phrase. In many applications, most of this work falls on the user, and it’s important to acknowledge the responsibility here of the makers of the application to ensure that the user is able and aware of how to securely store a recovery phrase backup.

 Many wallet-applications work with HD wallets and recovery phrases, and are interoperable, meaning you can change the application that can control your wallet should you wish (although there are some caveats depending on if they support just BIP32 or also BIP44).

+Payment codes have been popularised in wallets such as Samourai (no longer operational) and [Sparrow](https://sparrowwallet.com/).
 
 A downside to payment codes is that they require an additional on-chain transaction each time two users want to connect and use them. [Silent payments](https://gist.github.com/RubenSomsen/c43b79517e7cb701ebf77eec6dbb46b8?permalink_comment_id=4113680) are a new experimental proposal that prevents the need for this additional on-chain transaction at the cost of extra bandwidth for receivers.
