For Rearfe we built a bank-grade USDT (BEP20) payment gateway: QR checkout, on-chain confirmation, signed webhooks and automatic sweeps to treasury. Integrating it from your backend takes five lines of code.
No monthly fees or minimums · sandbox the same day · daily reconciliation included
payment = sdk.payment().create({
"external_reference": "order_42",
"amount_brl": "100.00",
"notification_url": ".../webhook",
})
# → {"address": "0x8f3a…9c21", …} “We integrated it in an afternoon and haven’t thought about it since: payments arrive, sweeps run on their own and reconciliation balances every morning.”
Final price: no setup fee, no monthly fee, no charge for webhooks or reconciliation.
A backend that can make an HTTP call. The SDK is five lines; you get a sandbox, docs and hands-on support until your first production charge.
Sweeps run automatically after on-chain confirmation, and daily reconciliation matches every transaction — with alerts if something is off.
A fallback poll checks pending payments every 60 seconds: no transaction goes unnotified.
None: you pay 0.99% + average network gas per confirmed transaction. Above $50,000/mo, custom pricing.
