When you fund the order, the coin sits in escrow rather than going straight to the vendor. The vendor ships, you confirm receipt, and only then does the coin release. If you never confirm, the order auto-finalises after a set window so the vendor is not left waiting forever.
The protection this gives you disappears the moment you confirm receipt, so never confirm before the package is in your hands, whatever the vendor says. That mistake, releasing early, is the single most common way a buyer throws away escrow. If something goes wrong, you open a dispute instead.
The final step covers receiving, confirming and, if needed, disputing.
