Integration overview

Assets and networks
Collection and payout support USDT on TRC / ERC and USDC on ERC only. Before collecting, configure a receiving address in the dashboard for the corresponding network and asset.

Where funds and fees live

  • USDT or USDC paid by the user goes directly to the merchant receiving address.
  • Collection fees come from the merchant pre-funded balance.
  • Payout amount and fees leave the merchant payout balance.
