Clipboard hijackers watch for crypto addresses you copy and replace them with a look-alike. Paste the address you meant to copy and the one now in your clipboard into the guard below: it compares them character by character and flags any difference.

These attacks rely on people checking only the first few characters. Attackers generate addresses that match the start and end.
Often you wouldn’t, until the funds go elsewhere. A pasted address that differs from the copied one is the clearest sign.
Only when you press its paste button, and only in your browser.
Use your wallet’s address book or QR codes, and send a small test amount first for large payments.
Paste the address from its source (the exchange, the invoice, the chat), then paste what’s in your wallet’s send field.
Copy the address, then start watching. Each time you come back to this tab, Zcan re-reads the clipboard and warns if it now holds a different address of the same kind.
Works only while this tab is open, and only if your browser allows clipboard reads (Chrome and Edge do after you allow it; Safari and Firefox ask every time). Clipboard contents stay on this page and are never stored.
