I poked around a little bit and I can't find much. TDex is a decentralized exchange that might be interesting. People are also doing shitcoins and NFTs on liquid.

But that's not what I'm talking about. I'm talking about 1) the bitcoin circular economy, and 2) HODLing. And especially people who like to do both. It is basically like on-chain bitcoin but faster and more private, and the trade-off is the risk that a majority of the 50 entities in the federation decide to attack you.

Compare that with running a lightning node. Not custodial lightning, but running a node. Huge pain in the ass, and privacy is still mediocre.

Fedimints may blow all of this out of the water. We shall see.
