Coinjoin transactions can look like normal transactions and avoid being noticed by exchanges, chainalysis etc. I have created a proof of concept to test different type of pools using musig2 and pre-signed transactions. Would appreciate any feedback to improve it. Repository:

There is also a playground to visualize these pools and transactions:

Simulate joinstr v2 coinjoin pools in the browser, no node, faucet or coins needed

It can be improved with covenants once the users are familiar with the musig2 version.

The old website has been moved to old.joinstr.xyz and a new minimalist dark-mode website is live at joinstr.xyz. Joinstr now has a community forum at forum.joinstr.xyz that uses Nostr and Squalk. The old SimpleX chat is dead.
