Yes - their work on key exchange is super cool https://keybase.io/docs/crypto/key-exchange

We did not want to require use of Keybase to use our dapp Audius, though I could see it making a lot of sense to offer a keybase integration as a potential option.

FWIW, Audius still supports Metamask too - web3 is all about giving users choice from our perspective.
