How well USDT ERC-20 fits SaaS

Excellent fit · Fit 75%

Make this coin your main payment method.

Pros

  • A stablecoin pegged to the dollar: your revenue does not depend on the exchange rate.
  • Good for large amounts: deep liquidity and counterparties trust it.

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.

Plans and subscriptions

Create a plan via the API — Moonvex issues invoices on schedule and sends you events.

Balance top-ups

A permanent deposit address per customer: every incoming transfer is a separate payment and webhook.

USDC and USDT

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

For a “top up your balance” model, deposit addresses are the right fit: each customer has their own permanent address, and you get a deposit.confirmed event for every top-up.

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 SaaS

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.

FAQ

Which currency should the price be in when customers pay in USDT ERC-20?

USDT ERC-20 is pegged to the dollar, so you can set the price in the coin or in USD; the amounts are nearly the same.

No: with crypto, the customer sends each payment themselves. Moonvex issues invoices automatically and reminds you about them with events.

Who pays the network fee?

The sender pays the transfer fee, as with any wallet. The service covers fund sweeps and gas for payouts.

How do I test the integration before launch?

The “Send test” button delivers a test webhook, and a real payment for a small amount checks the whole flow. There is no separate test network.

What address will the customer get?

A separate 0x… address per payment, or a permanent deposit address per customer.
