A white-label TRC20 payment gateway for businesses who want to accept and settle USDT without building blockchain infrastructure themselves.
Real on-chain transfers detected automatically — no manual checking.
Three steps from API call to settled funds.
curl -X POST https://quropays.com/api/v1/payin/create.php \
-H "Authorization: Bearer key_live_xxxx..." \
-H "Content-Type: application/json" \
-d '{"amount": 100, "order_ref": "ORDER-123"}'One API call creates a payin order and returns a hosted checkout link.
Customer scans and sends the exact (uniquely-suffixed) amount shown.
Webhook fires, your ledger updates, funds are available in the merchant portal.
Built for merchants who need real infrastructure, not a demo.
TronGrid-powered polling matches incoming transfers automatically — no manual checking required.
Mandatory TOTP 2FA plus a separate transaction password for every sensitive action, on both portals.
A separate sandbox API key pair completes instantly and never touches your real balance — test your integration safely before going live.
Every event delivery is signed so you can verify it genuinely came from Quropay before trusting it, with automatic retries on failure.
Date-range reports, daily settlement summaries, and revenue trends — exportable to CSV whenever you need them.
Every payout is reviewed and approved by an admin before it's signed and broadcast — with a full audit trail, not a black box.
Payin and payout fees are set per merchant, agreed with you directly — no hidden charges, no surprise deductions. Every fee is itemized as its own line in your ledger, and every report breaks gross amounts, fees, and net settlement apart clearly.
This is a crypto payment product — security isn't an afterthought.
