Description
GridPay is the first DePIN energy exchange to autonomously mint cryptocurrency tokens from real home solar exports. Texas homeowners earn GPT tokens every 15 minutes when their solar panels export to the ERCOT grid. Built by a solo founder with 3 AI agents — Nexus, Axiom, and Relay — who shipped production code, fixed live bugs, and deployed to a new blockchain while the founder networked at this event.
