In a major step toward securing the Web3 ecosystem, leading crypto wallets like MetaMask, Phantom, WalletConnect, and Backpack, have teamed up with cybersecurity non-profit organization SEAL to launch a real-time phishing defense network.
The initiative, powered by SEAL’s Verifiable Phishing Reports technology, aims to combat increasingly sophisticated phishing attacks that have plagued crypto users. By enabling users to submit cryptographically verified reports of scam websites, SEAL’s system can automatically detect and block malicious domains, without relying on manual review.
A decentralized immune system for crypto
SEAL’s new network will act like a decentralized immune system, allowing a single user’s report to protect the entire community. This marks a shift from reactive security to proactive, real-time protection.
“Drainers are a constant cat and mouse game like most of security, working alongside SEAL and their independent researchers it allows wallet teams like MetaMask to be more agile and apply SEAL’s research to practice effectively throwing a wrench at the drainer’s infra”, said Ohm Shah, Security Researcher at MetaMask.
Industry-wide collaboration for a safer Web3
WalletConnect’s CTO Derek Rein emphasized that SEAL’s scam domain database will enhance WalletConnect Certified protections, helping users avoid known phishing sites. Phantom and Backpack echoed the importance of integrating SEAL’s tools to safeguard users during everyday crypto interactions.
According to blockchain security firm SlowMist, there were 429 stolen funds reports in Q2 2025 alone, many of which stemmed from phishing and social engineering attacks. Meanwhile, data from the U.S. Federal Trade Commission (FTC) shows that 67,586 investment scams were reported in the first half of 2025, costing consumers $3.5 billion. Of that, nearly $939 million was lost through scams involving cryptocurrency as a payment method
By joining forces with SEAL, top crypto wallets are setting a new standard for real-time, decentralized security. With phishing attacks becoming more complex, using cloaking, offshore hosting, and rapid domain rotation, it is imperative that the crypto ecosystem needs to build a defense system that evolves as fast as the threats do.
