How well Ethereum (ETH) fits SaaS

As an extra option · Fit 25%

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

Pros

  • Good for large amounts: deep liquidity and counterparties trust it.

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.

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.

ETH and tokens together

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

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.

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 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 Ethereum (ETH)?

Set the price in USD with Ethereum (ETH) as the payment coin: Moonvex converts the amount and fixes the rate when the invoice is created.

Can I charge customers automatically, like with a card?

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

Are L2s (Arbitrum, Base) supported?

Not yet: Moonvex accepts payments on Ethereum mainnet, BNB Smart Chain, TRON, Solana, TON and Bitcoin.

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.

Is there an SDK?

Yes, the official Node.js SDK @moonvex/node, plus a REST API for any language.
