Features
A complete blockchain monitoring toolkit for businesses accepting USDT and USDC on TRC20, BEP20, ERC20, Polygon, and Arbitrum.
Continuous blockchain scanning for incoming USDT and USDC transfers. Automatic detection across TRC20, BEP20, ERC20, Polygon, and Arbitrum with configurable polling intervals.
HMAC-SHA256 signed webhooks delivered to your server when payments are detected. Automatic retry with exponential backoff and delivery tracking.
Use HD wallets (xPub) for automatic address derivation, or add your existing static addresses directly — perfect for small merchants with just one or two addresses. Share addresses across multiple concurrent payments with intelligent amount matching. Watch-only — your private keys never leave your device.
Clean, documented API to create monitoring requests, check payment status, and manage projects. Per-project API keys with role-based access.
Run multiple projects from a single account. Each project gets its own API keys, webhook URL, and isolated payment data.
Non-custodial architecture. Rate limiting, HMAC verification, 2FA support, and encrypted credentials. We never touch your funds.
Get instant Telegram alerts when payments arrive, expire, or need attention. Connect your account in seconds and choose which events to receive.
How It Works
PayzCore monitors your blockchain addresses and notifies you when payments arrive. You keep full control of your funds.
Step 1
HD Wallet: import an xPub for automatic address derivation. Static Wallet: add your existing addresses — no xPub needed. Perfect for merchants with 1–2 addresses. Watch-only — no private keys needed.
Step 2
Get your API key and configure a webhook URL. Use our REST API to create monitoring requests from your application.
Step 3
PayzCore continuously scans all supported blockchains for incoming USDT and USDC transfers to your monitored addresses.
Step 4
When a payment is detected, we send an HMAC-signed webhook to your server and an instant Telegram alert to your phone.
