Coinos does ecash. Right now, you can mint ecash from your wallet, but you can only redeem tokens minted from the Coinos mint. The ability to redeem tokens from outside mints is coming soon. It's only really missing on-chain, and the devs seem open to suggestions, so maybe we could lobby them for on-chain support.

Coinos also provides a lightning address that can also be used for NIP-05, and NWC that works great. I think it's on the road to perfection.
