I have written about the idea of group currency here.
I thought it would be fun to create one - it is a bit hacky but it should work:
If you want to join the group - apply here - all you need is an active forum profile that looks like a real human and you need to name your Circles profile here.
What I did:
Created a Gnosis Safe that administers this group:
Could also be a DAO:
I minted 1,000,000,000 “Circles Forum Group Tokens” (CFG)
I deposited those on an exchange: Mesa.eth.link
Now I added me to the group by simply placing 2 orders:
1: buy unlimited Martin Circles with CFG at price 1:1
2: sell unlimited Martin Circles for CFG at price 1:1
Given the unlimited supply of CFG this essentially means:
You can always convert Martin Circles into CFG, but you can only convert CFG into Martin Circles if the account still holds Martin Circles.
So the steps to add someone to this group are simple:
Create those 2 orders.
I already created some liquidity between the Group Currency and stable coins like USDC.
The system (mesa.eth.link) is smart enough to find “ring trades”. So basically when it sees: personal Circles can be traded for CFG - CFG can be traded for USDC then it will allow you to directly trade your Circles for USDC.
Once you are part of the group you can simply load your Circles account into a Gnosis Safe - and then use wallet connect (you find it in the Safe apps) to connect your Circles account to Mesa and trade some of your Circles. Alternatively you can just send your personal Circles (also via the Safe) to a fresh Metamask account and use that one to trade your Circles on Mesa.
