Monero fees and the confirmation count
Why the market waits for a specific number of confirmations, what that does to the feel of a checkout, and the small fee math that decides whether your payment clears on time.
Monero is the only coin the market accepts, and the reason is that it is the hardest of the common coins to trace. But the same property that makes it private makes the checkout feel slower than a card tap, because the market has to wait for the network to agree your payment is real before it releases the order into escrow.
How many confirmations, and why
The market waits for a set number of block confirmations before it treats a payment as landed. The count is chosen to be high enough that a rare double-spend is unlikely, and low enough that you are not waiting an hour to buy something. In practice that lands somewhere around twenty minutes, which is the number that surprises people the first time. The payment left your wallet, the market has not yet seen it, and the gap in between is the confirmation window.
During that window the order is in a holding state. You can see it, you cannot yet cancel it cleanly, and the vendor cannot yet ship. Most people assume something is broken. It is not. The network is just counting blocks, and the order will move on its own the moment the count is met.
The fee that decides timing
There is a second number that matters, and it is the transaction fee you set when you send. Monero fees are not fixed the way people remember them from other chains. They scale with the size of the transaction and the current network demand, and a fee that is too low means your transaction sits in the mempool longer than the confirmation window assumes. The practical rule is to let the wallet suggest a fee and not to shave it down to a penny. A slightly higher fee that clears in one block is cheaper, in time, than a minimal fee that clears in three.
When it is not worth worrying about
If your payment clears and the order moves into escrow within the expected window, there is nothing to do. The only time the fee and the confirmations become a problem is when the order is stuck in the holding state well past the usual window, and then the fix is almost always "wait a little longer" rather than "send it again," because sending again before the first one clears is how people end up paying twice.
