Introduction
ZynPay is a decentralized USDC payment SDK and smart contract router that lets merchants accept crypto payments with automatic fee-splitting and zero backend complexity.
Key Features
- MetaMask Native: Designed for the most popular wallet. No custom connector logic needed.
- Zero Backend: Fully client-side SDK. You don't need to run a server to process payments.
- Multi-Chain: Works on Base Sepolia and Arc Testnet today. Mainnet support coming soon.
New to Crypto Payments?
ZynPay abstracts away the complexity of smart contracts and gas fees. If you know how to use a React hook, you can accept USDC.
How It Works
ZynPay sits between your frontend and the blockchain. It provides a simple SDK to request payments and a Router smart contract to settle them.
1
Connect
Your customer connects their wallet to your application using the SDK.
2
Pay
SDK constructs a transaction sending USDC to the ZynPay Router.
3
Split
Router validates the payment and splits funds to merchant & platform wallets instantly.
