How Do Crypto Payments Work? A Plain-English Guide for Merchants

No jargon, no hype — just a clear walkthrough of what actually happens when a customer pays you in crypto, from the checkout button to the moment the money hits your balance.

"Accept crypto" sounds complicated until you see what is actually happening under the hood. It is simpler than the card networks you already use — there are just fewer middlemen. Here is the whole flow, in plain English.

The cast: wallets, coins and networks

Three words cover almost everything you need to know:

What happens when a customer pays

From the buyer's side it is a few taps. Behind the scenes, a payment gateway like CryptoPayr runs these steps:

  1. You request a payment. Your store tells the gateway "charge $50". This can be a plugin, an API call, or a reusable payment link.
  2. The gateway locks a rate. It checks the live exchange rate and shows the customer the exact amount of crypto to send, valid for a short window so neither side is exposed to volatility.
  3. The customer sends. They scan a QR code or copy the address into their wallet and confirm. The transaction is broadcast to the network.
  4. The network confirms. Miners or validators include the payment in a block. Each new block on top is a "confirmation" — more confirmations means more certainty the payment is irreversible.
  5. You get paid. Once enough confirmations arrive, the gateway credits your balance and fires a signed webhook so your system can mark the order paid automatically.

"But isn't crypto volatile?"

It can be — which is exactly why gateways exist. CryptoPayr prices the order in your currency (say USD), accepts whatever coin the customer chooses at the locked rate, and can auto-convert the proceeds into a stablecoin the moment they arrive. You quote dollars, you receive dollar-equivalent value, and the price swing between checkout and settlement is not your problem.

What about confirmations and waiting?

Confirmation time depends on the network, but for most stablecoin payments it is seconds to a couple of minutes — comparable to, and often faster than, a card payment clearing. The gateway tracks the transaction for you and only marks it complete when it is genuinely final, so you never ship against a payment that later vanishes.

Where the gateway earns its keep

You could do all of this yourself: run nodes, watch the chain, manage addresses, handle under- and over-payments, and reconcile everything. A gateway collapses it into one integration:

That is the entire model. A customer sends value over a network, the network confirms it, and a gateway turns that into a clean "order paid" event in your system. Create a free account and watch it happen end to end with a test payment.
