I see several tools being built, but there doesn’t seem to be anything that stands out. Fedimints are centralized and require lightning, which has its own issues. Liquid is centralized and was never meant to be a proper sidechain. Even their website says real sidechains are not possible yet. Plus they have something called Confidential Transactions, which is much different than private transactions. Privacy offers deniability, and that is essential to protect against $5 wrench attacks. There is a recent pull request to add "Deniability" to Core, but we will probably never see it 😞 I don’t know, maybe I’m missing something.
