Follow @partydao and /party for updates on party.app

So is there a group wallet trading app yet?

- Smart contract wallet

- Certain people have access to trade via delegation / voting

- You’re entitled to pro rata share of profits

- Farcaster channel or group chat for coordination

Is that @party?

yeah, party or any other dao based protocol,
they are just contracts with a voting system and can send any type of transaction and even setup a split contract 

I have built one of this systems where users could join using a zk proof in a hackathon some months ago.. it is open source.. let me find it..
