Why Merchants Choose PayCoinPro

We bridge the gap between complex blockchain infrastructure and simple e-commerce integration.

Truly Self-Custodial

Funds go directly to your HD Wallet addresses. We never hold your private keys, ensuring you have 100% control over your assets at all times.

Real-Time Settlement

Listen for incoming transactions via webhooks. Automate order fulfillment the second a blockchain confirmation occurs.

Multi-Chain Support

Accept Bitcoin, Ethereum, TRON, and stablecoins like USDT & USDC across multiple networks with a single unified API.

Unique Addresses

Every invoice generates a unique deposit address derived from your xPub. No more payment conflicts or reconciliation nightmares.

Merchant Dashboard

Track invoices, monitor balances per network, and manage API keys in a clean, comprehensive merchant panel.

Dev-First API

Built by developers for developers. Typed SDKs, predictable REST endpoints, and detailed documentation make integration a breeze.
