Non-custodial
Funds go to your wallet, from your xpub. We hold no key of yours and no balance of yours.
Payment engine
Crypto payments that go straight to your wallet.
A non-custodial crypto payment processor for subscriptions and one-time sales. Funds land at addresses derived from your own xpub. We never hold them.
- Non-custodial
- USDT and USDC
- 7 networks live
- Flat monthly price
Money flow
Payer, then your wallet.
The payer picks a network and sends USDT or USDC to a fresh address of your xpub. The processor watches the chain, confirms the amount and signs a webhook to your server. No balance sits with us.
What it is
A processor, not a custodian
dig2pay invoices, watches the chain and reports the result. Your keys and your money stay yours.
Subscriptions and one-time sales
Renewals, grace periods, proration and a price per subscription, or a single invoice for a single sale.
Integrates in an afternoon
Five REST routes and signed webhooks. Use the hosted widget or draw the checkout yourself.
How it works
From form to first invoice
You pay for the plan with the same processor you are about to use.
- Fill the Connect form. Business details, webhook URL and your xpubs.
- Pay your plan. In USDT or USDC, through this same processor.
- Receive your keys. An API key and a webhook secret, shown once.
- Integrate. Follow the docs and create your first invoice.

Features
Built for correct accounting
Every line below is code that runs in production.
The payer picks the network
One invoice carries every option: each network and asset, with its own address and exact amount.
Two ways to check out
Embed the hosted widget, themed to your brand, or build your own UI on the API. Both are permanent.
Signed webhooks with retries
Every delivery is signed. Failures retry with backoff and are kept in a dead-letter list.
Subscriptions and one-time payments
Recurring plans, single sales, proration on plan changes and a price per subscription.
Exact-amount accounting
Partial payments and overpayments are reported as they are, never rounded away.
Reorg-safe confirmations
A payment counts only when it is final. If the chain view diverges, the processor halts instead of guessing.
Live widget
This is the real checkout
The hosted widget in demo mode. Pick a network, switch the theme. Your page passes colours as tokens and keeps its own look.
Prefer your own screen? Read the invoice over the API and draw the payment page yourself.

FAQ
Short answers
Who holds the money?
You do. Payments go to addresses derived from your xpub. We never have your private keys.
What are the fees?
Only the flat monthly plan. Network gas is paid by the payer.
Refunds?
Refunds are manual: you send them from your wallet and record them.
Which wallets work?
Any wallet that exports a BIP44 account xpub. Verify the derived addresses before you go live.
Can I test first?
Yes. The demo widget above runs in demo mode, and the docs describe test invoices.
What if I stop paying?
After the grace period, new subscriptions are paused. Existing ones keep renewing.
