Not so much clearnet but rather a whirlpool coordinator or the finishing of decentralization of the coordination which was very close. Doubt to see that in Sparrow until the Samourai case is obsolved. However there is promising elements to whitlpool returning in a decentralised fashion over soroban and dojo nodes with Ashigaru.

Would love someone to pick up the code as an anon. Craig didn’t think the lunacy would get this far. Told are here, let’s make em happen.
Wasabi Wallet and BTCPay Server already have decentralized coinjoins thanks to Nostr. The coinjoin protocol used in those wallets is far more block space efficient and private than Sparrow's Whirlpool, here's the last coinjoin tx I coordinated: https://mempool.space/tx/e05d753f892ec0d6aca2f7946e8a9c39dd9755922ad2c3d8ea28d2180815db83
There are other solutions, but I liked the Sparrow one the best. I am also dubious of Wasabi, but maybe don’t know enough on that one.
