LNbits

Simple Python lightning-network wallet/accounts system. Use https://lnbits.com, or run your own LNbits server!

LNbits is a very simple server that sits on top of a funding source, and can be used as:

• Accounts system to mitigate the risk of exposing applications to your full balance, via unique API keys for each wallet!
• Fallback wallet for the LNURL scheme
• Instant wallet for LN demonstrations

The wallet can run on top of any lightning-network funding source such as LND, lntxbot, paywall, opennode, etc

LNbits is still in BETA. Please report any vulnerabilities responsibly

LNbits as an account system

LNbits is packaged with tools to help manage funds, such as a table of transactions, line chart of spending, export to csv + more to come..

Each wallet also comes with its own API keys, to help partition the exposure of your funding source.

LNbits as an LNURL-withdraw fallback

LNURL has a fallback scheme, so if scanned by a regular QR code reader it can default to a URL. LNbits exploits this to generate an instant wallet using the LNURL-withdraw.

https://github.com/btcontract/lnurl-rfc/blob/master/spec.md

Adding /lnurlwallet?lightning="LNURL-WITHDRAW" will trigger a withdraw that builds an LNbits wallet. Example use would be an ATM, which utilises LNURL, if the user scans the QR with a regular QR code scanner app, they will stilll be able to access the funds.

LNbits as an insta-wallet

Wallets can be easily generated and given out to people at events (one click multi-wallet generation to be added soon). "Go to this website", has a lot less friction than "Download this app".
