Clipboard malware, and the thirty second check that beats it
Some malware quietly swaps the address you copied for its own. One small habit makes it useless.
A clipper is a small piece of malware that watches your clipboard. When it sees something shaped like a crypto address, it swaps it for an address the attacker controls. You copy your address, paste it, and the field now holds someone else's. It runs on computers and on phones.
The habit that beats it
- Copy the address from your wallet's receive screen.
- Paste it.
- Compare what you pasted with what the wallet shows. Check the start, the end and a piece of the middle.
Thirty seconds, and the clipper has nothing, because you catch the swap before a single coin moves.
More good habits
- Install wallets only from the official site or the official app store listing.
- Stay away from cracked software and browser extensions you do not really need.
- Use the QR code when you send from your phone.
- For large amounts, send a small test first.
On SwapAnonymously
As soon as the swap is created, your receiving address is shown in full on the swap page, before you send anything. Take one last look there and compare it with your wallet. Your deposit address comes with a QR code, so your phone wallet can scan it directly.
Quick answers
Does scanning a QR code protect me?
Scanning with your phone skips the computer clipboard entirely, which helps. Still compare the result with the address on screen.
Does SwapAnonymously check the address I paste?
We check that it fits the coin and network you picked, and your swap page shows it in full before you send anything. Whether it is really yours is something only you can confirm against your wallet.
