How well USDT ERC-20 fits digital goods

As an extra option · Fit 40%

Enable it for customers who hold this coin, but pick another one as the main method.

Pros

A stablecoin pegged to the dollar: your revenue does not depend on the exchange rate.

Keep in mind

The network fee is noticeable: for small orders add a cheaper network to the checkout, such as BEP-20, TON or Solana.

Network: Ethereum
Standard: ERC-20
Coins: USDT, USDC, ETH
Best for: orders from a few hundred dollars

Automatic delivery

The product goes to the customer the moment the payment is confirmed.

No double delivery

Every event is signed and has an id, so it’s easy to make processing idempotent.

USDC and USDT

The two main stablecoins on one network — customers pay with whatever they have.

Speed matters for digital goods: the customer wants the key right away. Moonvex credits the payment after confirmation by two network nodes and sends the webhook immediately.

Network fees on Ethereum are higher than on TRON or BSC, so it makes sense to offer ERC-20 for large payments and B2B invoices, with alternatives on other networks for small orders. One payment page can show several options.

Recommended coin set for digital goods

To cover most customers, enable on the checkout page: USDT BEP-20, USDT on TON, USDT and USDC on Solana. 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.
