FlowPay

FlowPay is an agentic payment infrastructure, a backend engine that functions like a payment operating system. It allows AI agents and humans to express payment instructions in plain language and have them executed reliably across multiple payment rails. It is not a wallet or a consumer app; it is the layer between instruction and settlement.

FlowPay relies on a multi-layered architecture:

• Intent AI: Google Gemini 2.5 Flash running on a Node.js Agent Service.
• Execution & HTTP Payments: A Bun + Express server protected by the x402 protocol, using Base Sepolia USDC for machine-to-machine micro-payments.
• Automation: Chainlink Runtime Environment (CRE) handling decentralised off-chain compute and conditional triggers.
• On-Chain Smart Contracts: Written in Solidity and deployed on Ethereum Sepolia (utilizing Viem for interaction). Contracts include FlowToken, FlowIntentFactory, FlowAIRegistration (ERC-721), and FlowStaking.
• Fiat On-Ramp: Transak widget integration.
• Frontend: React 18, Vite, shadcn/ui, and RainbowKit for wallet connections.
