# This is an experimental feature, as the NIP has not been merged at the time of writing this.
|
|
# NIP60/61 support so called nutzaps, or in other words, if a user carries their wallet on Nostr
|
|
# They can use it to interact with DVMS. In this tutorial we will once again keep our simple example
|
|
# But will focus on what needs to be done in order to make it work.
|
|
|
|
|
|
# Important: In order to make this work you need to manually install the cashu library in your main environment.
|
|
# Also see https://github.com/cashubtc/nutshell
|
|
# Depending on your system you might need to install some further dependencies. Please see the readme in the above link.
