What would be the best way to use Supertokens (self-hosted) with a crypto wallet so people could create or recover their Ethereum keys or encrypt the keys with a login. I guess this would only be possible with MPC or Web3 authentication correct? If so is there a roadmap for when this would be coming?

hey @acamarata we don't suppor that yet. We don't have a definite timeline for it either. Perhaps sometime next year though. That being said, you can still use supertokens for session management post authentication with web3

Do you have any documentation for how to do that so I can pass to my team?
