Crypto payments and subscriptions for SaaS
Plans, subscriptions, deposit addresses and webhooks — everything you need to sell a subscription to your service for USDT, USDC or ETH.
Sign-up is open, no monthly fee.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.
SDK and idempotency
@moonvex/node, Idempotency-Key, signed webhooks and a delivery log.
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.
For a fixed monthly price, use plans and subscriptions: the next invoice is created automatically, and cancellation is a single request.
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
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.
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.
Which languages are supported?
The REST API works with any language; the official SDK is for Node.js.
