Hello Kealan,
with MPC as far as I remember is possible to create a distributed
application like Hashcorp Vault, that is able to keep secrets.
Technically we could create a cloud service for securely storing and
accessing secrets for the Apache ecosystem. A secret is anything that you
want to tightly control access to as API keys, passwords, certificates or
cryptographic keys. I admit my basic ignorance about MPC but i looked this

I know that you've used that for implementing your wallet. I can commit a
couple of hours a week if there is someone who is able to design with me
and since we're living in the same country, open to a discussion.
Best Regards,
Giorgio.
