Pullpay
Autonomous Web3 subscriptions: Agents handle recurring payments via ENS, AXL, and Uniswap.

About
PullPay solves blockchain's "push payment" problem by enabling trustless, recurring subscriptions. Users authorize subscription policies through ENS text records (e.g., `1:USDC:2592000` for $1 monthly), and autonomous agents handle the entire flow: invoice discovery, amount validation, dynamic token swaps, and settlement—without manual intervention. Built for merchants and consumers in Web3 SaaS, media, and DeFi.
How it's made
PullPay layers four infrastructure pieces: 1) ENS text records store authorization policies on-chain; 2) Gensyn AXL provides encrypted P2P mesh for agent communication; 3) Uniswap V3's `exactOutputSingle` handles dynamic asset conversion (e.g., WETH→USDC); 4) KeeperHub MCP executes settlement with gas optimization and MEV protection. The backend is Python FastAPI with OpenZeppelin Solidity contracts on Sepolia. The frontend is Next.js + Tailwind. Database: PostgreSQL tracking subscriptions and payment history.
