02Payment modes

Three ways to collect, one money path

Pick the mode that matches your business; the flow underneath stays identical.

Order mode

Best for: E-commerce and platform orders
Addressing: One address per order, preset amount, auto-matching
Automation: Webhooks, plus APIs for over-, under- and late payments

Deposit mode

Best for: Account top-ups and stored value
Addressing: A fixed dedicated address per user, unlimited deposits
Automation: Webhooks with automatic sweeping

Subscription mode

Best for: SaaS recurring billing
How it works: Authorized auto-debit, built on order mode

The money path is identical across modes: collect → screening → sweep to a dedicated pool → convert → fiat payout. Risky funds are returned to the sender.

05Your questions

Straight answers on collection

What happens when a customer overpays, underpays or pays late?

Standard APIs cover overpaid, underpaid and late payments, so exceptions resolve inside your flow instead of a support queue.

What happens when a payment fails screening?

Funds that fail screening are never credited to your account. They are returned automatically to the sender and every return is recorded for audit.

Can the checkout carry our brand?

Yes. The checkout is fully customizable and ready for desktop and mobile, so the payment page stays yours.

Do you support recurring billing?

Subscription mode builds on order mode with authorized auto-debit, which suits SaaS recurring billing.
