GridMint is a decentralized physical infrastructure network (DePIN) protocol that enables real-time micro-energy trading between autonomous agents. Built on Arc Testnet with Circle USDC settlement, the system demonstrates how blockchain can power next-generation energy markets with radical cost efficiency, achieving 24,700× lower gas costs compared to Ethereum. The protocol features autonomous solar producers, battery storage operators, and consumer agents that trade energy every 3 seconds using game-theoretic pricing mechanisms. Schelling point convergence ensures fair market prices through multiplicative weights learning, while Shapley coalitions enable battery-solar cooperation for grid stability. An x402 paywall demonstrates API monetization, and Google Gemini AI provides real-time market analysis and autonomous battery trading decisions. All transactions settle on-chain via Circle USDC, with verifiable proof available on ArcScan. The system showcases the future of micro-commerce: instant, low-cost, autonomous payments at scale.

"Real-time micro-energy trading every 3s with Schelling-point convergence + Shapley coalitions + multiplicative-weights learning. Gemini for market analysis, x402 for API monetization, USDC on Arc. The 24,700x gas savings vs Ethereum is exactly the kind of claim Arc was built to enable. Strong DePIN narrative and serious game theory."
