How well Ethereum (ETH) fits online stores

As an extra option · Fit 25%

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

Pros

  • One of the coins buyers know best, which means fewer abandoned payments.

Keep in mind

  • The coin’s price moves: set the price in USD and the amount is converted at the rate fixed when the invoice is created.
  • The network fee is noticeable: for small orders add a cheaper network to the checkout, such as BEP-20, TON or Solana.

Order ↔ payment

Pass your order number in orderId — it comes back in every webhook.

Prices in dollars

Set the amount in USD — it’s converted to the chosen coin at a locked rate.

ETH and tokens together

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

A typical integration takes an evening: one request to create a payment at checkout and a webhook handler that marks the order as “Paid”. Repeating the request with the same Idempotency-Key won’t create a second payment, even if the customer clicks the button twice.

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 online stores

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