In-App Bitcoin Lightning Support (Tipping/Sending Bitcoin To Other Users)

It would be amazing if users were able to send bitcoin to one another. This could also easily be extended to guilds and bots too. This also feels in-line with some of the other things Discord are working on which allow communities and creators to charge money through Discord. It benefits everyone, while also being super simple for Discord to implement. The bitcoin lightning network allows users to instantly send bitcoin practically for free.

How it can be implemented:

- Accounts can be given the option to enter a LNURL (https://github.com/fiatjaf/lnurl-rfc/tree/master). This is usually represented as a QR code, so it should be as simple as scanning a QR code from an app. For a list of implementations where this LNURL can be obtained from, see https://github.com/fiatjaf/awesome-lnurl#lnurl-pay Discord just need to store the QR code data, so the QR code can be displayed.

- When the user's profile is clicked on, this QR code should be displayed to the person who clicked on the profile. If they wish to send any bitcoin to the user, they simply scan the QR code with a compatible app (see https://github.com/andrerfneves/lightning-address/blob/master/README.md#wallets-supported for a list) which will then prompt them to choose an amount and complete the transaction by sending that amount directly to the user's lightning wallet.

This method is very simple and doesn't require any messy pre-funding or exchanging money for credits. Plus, it utilises the native currency of the internet and requires no involvement from Discord. Discord just associate a LNURL with a Discord account.

Jack Dorsey has also heavily hinted towards adding something like this to Twitter, so it will be interesting to see how they implement it and how it all goes.

Being able to send bitcoin to other users or communities is a nice way to give back to others, similar to reddit rewards in many ways. Additionally, it could also be used by bots to provide rewards for games. It allows a lot of freedom, so the opportunities it offers are practically limitless.
