I have set up an instance to host an unofficial community centered around the cryptocurrency Nano (XNO): https://nano.garden
The purpose of the instance is to have a space in the lemmyverse to discuss the Nano cryptocurrency project and the community projects being built around it.
I want to play around with the integration of nano into the fediverse, but I don't want to do this in an invasive manner, so I've set up an instance to try to build some of these tools directly into the UI without inconveniencing others. Anyone else who needs an instance to try out their own nano-related inventions is more than welcome to try them out here. You may consider it a nano-playground in the Lemmyverse.
I chose Nano for this because I know that there are many open source projects related to 'tipping bots' and faucets, transfers are very fast and free, and the community that I've encountered is nice. I also found out that there is already a nano tipping button implemented in a mastodon instance, and I may draw some inspiration from that: https://xno.social/home
The creator of the tool is the admin of lemmings.world, and the tool is hosted at schedule.lemmings.world. So, if you have a user at lemmings.world, you can use this tool without having to trust a third-party.
If you don’t have a user there, you can create a user in that instance for the purpose of creating scheduled posts. Removing the need to trust two parties rather than one.
And, of course, since the source code is open anyone else can attach this to their own instance! Pretty cool.
