Three checks that catch almost everything
Run these before you type anything sensitive anywhere.
Check the domain, character by character
The app lives at polycopy.app. Type it into the address bar yourself rather than following a link. Lookalike domains swap letters, add hyphens, or use a different suffix.
Check who started the conversation
We reply, we do not initiate. If they contacted you, the answer is no.
Check what is actually being asked for
A private key, a seed phrase, or a transfer of funds are never legitimate requests. There is no exception, no verification step, and no emergency that changes this.
