Quick Escrow dapp to make people come ON TIME
The problem RSVP solves
It is a simple escrow contract where a "planner" and "counterparty" both uphold 0.01 ETH as collateral in the contract before some meeting point. After physically arriving at the point, they receive their collateral back. Arriving late means a penalty incurred. After a certain window of time, their collateral is forfeited to the other side altogether.
Challenges I ran into
Using Chainlink's new "CRE" and encryption technologies is a PAIN. I didn't get over the bug unfortunately that would allow me post the encrypted location from an API call.
Use of AI tools and agents
They helped me build it, that's it.
