Some ideas are Monad specific

By MPC do you mean something like Privy, Turnkey etc…?

I use CDP Wallet API. https://docs.cdp.coinbase.com/wallet-api/docs/welcome

Btw, I implemented one of your ideas but in opposite direction. Currently, You can send tips to others by like/recast or emoji in quotes/replies of their casts but not the other way around. I think I can implement that one pretty easily.
