Clipboard guard
Clipboard hijackers watch for a copied crypto address and silently swap in the attacker’s. The paste looks right at a glance, and the payment can’t be reversed. Compare before you send — everything here runs in your browser.

Paste the address from its source (the exchange, the invoice, the chat), then paste what’s in your wallet’s send field.
Watch mode
Off
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.
