Large amounts

USDT and USDC on Ethereum, TRON, BSC and Solana.

Payouts to counterparties

Payouts via the API or the dashboard, with the fee calculated upfront via quote.

ETH and tokens together

One Ethereum address accepts both ETH and USDT/USDC — the customer picks the coin.

B2B is about predictability and bookkeeping. Before a payout you can get an exact calculation of the amount to be debited, and choose the fee mode — add it on top or deduct it from the amount.

ETH suits customers who received it as income or hold it long term and don’t want to swap into a stablecoin before paying.

Recommended coin set for B2B invoices

To cover most customers, enable on the checkout page: USDT TRC-20, USDT ERC-20, USDT BEP-20. The customer picks the network, and every payment lands on one project balance.

One request to create a payment

The response contains the address, the exact amount and a link to a ready-made payment page. Status updates arrive via HMAC-signed webhooks.
