Project Description

This Worldcoin-powered, human-only booking mini-app restores capital efficiency to customers by redistributing yield from anticipated payments up to the booking date. Bookers receive their fair share of low-risk, risk-adjusted yield—previously captured by centralized entities. It incentivizes all users to pay earlier and gives service providers the peace of mind of being paid on time, instead of waiting up to two months. The app also abstracts complexity for Web2 users by enabling zk-proof of sufficient funds.

How it's Made

When the booking is initiate, even if only a single member has paid, the pool starts generating yield from day one. This mini-app leverages Beraborrow CDP positions, using deposits as collateral to mint the NECT stablecoin, which seeks the best risk-adjusted returns from external pools. For non web3 users, it leverages Revolut web proofs to verify that a user has sufficient funds, even if they are not yet part of the pool.
