Choosing a payment method

A quick comparison of Invoices, Deposits, Address provision, and Withdrawals to help you pick the right building block.

Cryptonly has four payment primitives. They share the same underlying pool-address and confirmation infrastructure, but fit different use cases.

Primitive	Use it when	Amount	Address reuse	Webhook event
Invoice	Checkout — customer pays a fixed price for an order	Fixed, priced in fiat	New address per invoice	invoice.statusChanged
Deposit	A single crypto top-up to your balance, outside of checkout	Flexible, at or above a currency minimum	New address per deposit	deposit.statusChanged
Address provision	A customer may send several top-ups over time (e.g. a recurring depositor)	Flexible per payment	Same address reused until it expires	deposit.statusChanged per payment
Withdrawal	Paying funds out of your balance to an external wallet	Merchant-specified	N/A — sends out, not in	withdrawal.statusChanged

Still not sure?

• Selling a product or service with a known price? Use an Invoice.
• Accepting an open-ended top-up (for example, funding a customer's in-app balance)? Use a Deposit.
• Expecting the same customer to top up more than once? Use Address provision instead of creating a new deposit each time.
• Sending funds out to a customer, supplier, or your own external wallet? Use a Withdrawal.

Every primitive is backed by the same on-chain monitoring pipeline — see Onchain confirmations for confirmation requirements and Supported currencies for available assets and minimums.
