Introduction

Pontoon is merchant-side payment infrastructure: buyers send USDT; settlement, Energy, and reconciliation stay with you.One integration covers hosted checkout and gas sponsorship on Tron, BNB Smart Chain, and TON.

Two products

  • Checkout — unique USDT address per order, payment watch, signed webhook, resource provision, and net sweep to your treasury. Bridge fee 0.25%, $0.08 minimum, fuel at live cost.
  • Sponsorship — provision Tron Energy, BNB, or TON to addresses you control. Prepaid debit is resource cost + $0.02 + 10% markup + a $0.05-floor platform fee.

Wallet-level gasless (GasFree, Tonkeeper Battery, and similar) answers whether the sender must hold a native token. Checkout answers whether the merchant deposit address can be swept and reconciled. They are not substitutes.
