Base

if you had $100k, what would you build on Base x Farcaster?

assume you also have: 

- a solid group of mentors with high rep on Farcaster (ability to get attention to whatever you build)

- dev support

a social/public goods 'DeFi' platform that comprises of an orderbook DEX for mutual aid connections ie linking providers of surplus resources (leftover food, used furniture) with recipients in need

+ a prediction market allowing users to bet on pop culture ish outcomes

^ similar to Polymarket but more specific in focus and structured as a DAO

Love the idea of a local matching market for mutual aid

Yes the locality aspect and ease of communication is key
