01Side by side
| Your own wallet address | A payment gateway | |
|---|---|---|
| Matching a payment to an order | Manual — by amount, time or asking the customer | Automatic — a one-time address per invoice |
| Price in fiat | You convert by hand and the rate moves | Rate locked when the invoice is created |
| Underpaid or late payment | You notice, or you don't | Flagged with the shortfall; late payments detected |
| Telling your system it was paid | You check an explorer | Signed webhook |
| Wallet control | You hold the keys | Depends on the gateway — managed or not |
| Cost | Network fees only | Gateway fee as well |
| Customer privacy | One public address links every customer's payment | A different address per payment |
02When a plain address is enough
- A handful of payments, where you can match each by hand.
- Donations or tips, where attribution doesn't matter.
- You want to hold the keys and no software between you and the payer.
03When a gateway starts to pay off
- Two customers pay the same amount within minutes and you can't tell whose is whose.
- You price in dollars, and the coin moved between quoting and paying.
- Orders must fulfil automatically when payment confirms. See how a crypto payment gateway works.
- You need a clear policy for partial and late payments — see handling underpaid and late payments.
Choosing one is covered in how to choose a crypto payment gateway.
Questions
- Do I need a payment gateway to accept crypto?
- No. You can publish a wallet address. You need a gateway when you must attribute payments to orders automatically, price in fiat with a locked rate, handle underpaid or late payments, or trigger fulfilment from a webhook.
- Why use a different address for each payment?
- A unique address per invoice lets the system attribute a deposit to exactly one order, and avoids linking every customer's payment to a single public address.
