Why does the receiving address matter more than the sending address in a no-KYC swap?1
The receiving address is more important than the sending address because it is the only place your swapped funds can actually arrive. Once you confirm a no-KYC swap, you usually cannot redirect the transaction, so an error here often means the coins are gone from your control for good.
Think of the sending address as your departure gate and the receiving address as the destination on a plane ticket. If your destination is one character off, getting on the right plane does not help: you land somewhere you never intended to be. In a no-KYC swap, there is no support desk that can call the airport for you.
Copy-paste mistakes
A clipboard can hold an old address, and a single wrong character sends funds to a different wallet.
Wrong network selected
Sending coins to an address on a different chain can make them unreachable in practice.
Address belongs to someone else
If you paste a stranger’s address by accident, there is usually no recall mechanism.
The sending address matters less because the swap service knows what you sent once the transaction appears in the mempool. The real risk sits on the side you control: the destination wallet. Before you confirm, read the last four and first four characters of the receiving address, and compare them against the wallet you are actually trying to fill. Do not rely on the middle part alone.
A second practical rule: do not type the destination by hand. Paste it, then check the visible prefix and suffix against your own wallet. If the service lets you scan a QR code, that is often safer than copying a long string from a chat window.
Tip
Keep a small note with your most-used receiving addresses. It is faster to compare against a saved copy than to rebuild the address from memory.
