Phoenix.lol — USDT TRC20 Payment Gateway for Invision Community

Accept USDT Tether (TRC20) payments directly on your Invision Community 4.x site — no third-party processors, no fees, full control.

What it does

This payment gateway integrates USDT Tether on the TRON (TRC20) network into Invision Community's Commerce (Nexus) module. When a customer checks out, the gateway converts the invoice total to USDT at the current live exchange rate, displays a payment page with a QR code, and automatically confirms the order once the blockchain transaction is detected.

Key Features

• Live exchange rate — fetches the current USDT rate from Binance or CoinGecko (no API key required), with automatic fallback between sources. Rate is cached for 5 minutes to reduce API calls.

• QR code payment — generates a standard tron: URI QR code containing both the wallet address and exact USDT amount. Compatible with all major TRON wallets (TronLink, Trust Wallet, etc.).

• Automatic blockchain monitoring — polls the TronGrid API every 7–12 seconds to detect incoming USDT TRC20 transfers. No webhooks or cron jobs required.

• Confirmation progress display — once a transfer is detected, the payment page switches to a live confirmation counter showing progress toward the required number of confirmations (e.g. 10 / 20). The counter updates in real time.

• Automatic order completion — when the configured confirmation threshold is reached, the invoice is marked as paid, the customer receives a notification, and they are redirected to their order.

• Countdown timer — a payment window timer (configurable, default 60 minutes) is shown to the customer. Expired invoices are automatically refused.

• Non-custodial — payments go directly to your TRC20 wallet. The gateway never holds funds.
