Quick answers
Before you send money, check the recipient's wallet address, domain, and phone number against the GACS registry — a match means the identifier has already been reported for fraud.
How do I check if a payment request is a scam?
Verify the recipient's wallet address, website domain, and phone number against the GACS registry, confirm the request through a channel you initiated yourself, and never act on urgency or a changed payment detail sent by message or email.
How can I tell if a crypto wallet address is safe?
Run the address through the GACS wallet checker. A listed address has been reported for fraud. An unlisted address is not proof of safety — it may simply be new, so also verify the counterparty independently.
What is invoice or payment-redirection fraud?
It is when an attacker intercepts or spoofs an invoice and changes the bank or wallet details so your payment goes to them. Always confirm changed payment details by phoning a number you already had on file.
