AuraBid

An auction house on-chain: every bid and settlement happens live on Monad. Built in a weekend with Salami Azeez for the Monad Blitz Lagos hackathon hosted by Web3Afrika.

The core of it is proxy auto-bidding. You set a maximum and an increment percentage, sign once, and the contract outbids competitors on your behalf. Two auto-bidders going head to head cascade against each other and resolve inside a single transaction — which only works because Monad's sub-second finality and gas costs make a chain of bids cheap enough to settle atomically.
