Interesting I need to catch up on Fedi type systems. Any good resources to learn about them you recommend?
Great place to start. Easy to run yourself and also do multisig with whoever you select https://cashu.space/
Here's fedimint. Fedi (for profit co.) Is really only one building on it, to be released. Multisig available too for mints. Still great to see https://fedimint.org/
