About CoinPay

CoinPay is a crypto payment gateway for merchants and developers who want to accept payments in digital currencies. It offers payment creation through an API, real-time status updates, automatic fee handling and a hosted demo that simulates the flow on a testnet.

Supported networks listed on the site include Bitcoin, Ethereum, Solana, Polygon, BNB Chain, XRP Ledger, Cardano, Dogecoin, Bitcoin Cash and Lightning, plus USDC and USDT on several chains. Built-in escrow holds funds until both parties are satisfied and can use 2-of-3 multisig, and a web wallet keeps keys in the browser. The site says no KYC is required and notes that payments sit at an address it controls until forwarding completes.

The homepage describes the code as MIT licensed and open source, and it provides a command-line installer and documentation for agents. Fees are 0.5 to 1 percent per transaction depending on plan.
