PayVVM Gasless$PYUSD

PayVVM is a gasless payments, payroll, and subscription platform using PayPal USD (PYUSD). It’s built on EVVM, a virtual blockchain running entirely on smart contracts—no extra infrastructure required. Users can send PYUSD or MATE tokens using signed messages (EIP-191), executed by EVVM fishers who earn staking rewards. It includes PayVVM Scan, an Etherscan-like explorer that visualizes EVVM transactions using Envio HyperSync for real-time indexing—2000× faster than RPC calls. Everything is open-source, modular, and deployed on Sepolia for demo, paving the way for frictionless, user-friendly Web3 payments.

The frontend is built with Next.js, TypeScript, Tailwind, Wagmi, Viem, and RainbowKit. The project integrates three core technologies:

EVVM — enables gasless execution, staking (Fishers), Treasury bridging, and MATE token rewards.

Envio HyperSync — powers the explorer and live transaction stats with ultra-fast blockchain reads.

PYUSD (PayPal USD) — stablecoin used for all payments and payroll flows.

The app runs on the Sepolia EVVM ID #1000 deployment. Backend logic is modularized in Foundry contracts, and frontend queries combine HyperSync, direct RPC, and optional Envio Indexer for hybrid reliability. Deployed via Vercel, PayVVM demonstrates how on-chain payments can feel instant, gasless, and enterprise-ready.
