Looks like with FIP 8 there is some work going on the enable Account Abstraction/Smart Accounts on Farcaster. I put together this proof of concept of what applications built on Farcaster could look like if this was enabled.

For this Demo I created a "mini" version of Farcaster. 2 Smart contracts - one takes care of creating FID and FNAME and the other takes care of storage, an abridged version of things work today. 

Deployed on Polygon Mumbai just because I had an abundance of Polygon Mumbai USDC and wanted to showcase a tipping feature.

Was also super fun using Privy to help build the Social auth side of things. Biconomy is Signer Agnostic so any auth provider or wallet provider that allows you access to the signer is compatible!

Tipping feature is powered by Session Keys - we have session key validation modules deployed on our Smart Account Platform at Biconomy which is powering this demo. This is cool because you can now unlock onchain experiences in your dApp but still keep the same fluid experience of not having to sign every transaction.
