Base transactions are irreversible. Once you send funds to a malicious address, there is no way to recover them. Scammers exploit this by impersonating legitimate services, creating phishing sites, and distributing compromised wallet addresses.

Common scams targeting Base users include address poisoning attacks (where scammers send tiny transactions from look-alike addresses), clipboard hijacking malware that replaces copied addresses, fake airdrops that lead to phishing sites, and social engineering scams on social media.

By scanning addresses with Crypto404 before sending funds, you can check whether an address has been reported for fraud, appears on government sanctions lists, or matches known suspicious patterns. This simple step takes seconds and can prevent devastating financial losses.
