SEAL Leads Web3’s ‘Decentralized Immune System’ as MetaMask and Phantom Join Global Anti-Phishing Alliance

As phishing scams drain over $400 million in crypto this year alone, a powerful new alliance led by the Security Alliance (SEAL) is rising to fight back.

In a landmark collaboration, MetaMask, Phantom, WalletConnect, and Backpack have joined SEAL to launch a global phishing defense network — a real-time, decentralized security system designed to detect and neutralize threats before they spread across the crypto ecosystem.

Described as the industry’s first “decentralized immune system,” SEAL’s new network enables verified phishing intelligence to move instantly across participating wallets.

The mechanism works through SEAL’s Verifiable Phishing Reports, a system that allows users and researchers worldwide to submit evidence of phishing sites. Once verified, these reports are automatically distributed to all connected wallets, helping them block malicious domains in real time. SEAL explained in a statement.

“This means quicker response times to new phishing threats and more funds saved.”

By linking leading wallets under one shared defense protocol, SEAL’s network creates a continuous feedback loop — where every verified report strengthens the entire ecosystem’s resilience against attackers.

MetaMask and Phantom Rally Behind SEAL’s Initiative

For the first time, wallet competitors are uniting under a single, decentralized security standard. “Drainers are a constant cat-and-mouse game,” said Ohm Shah, a security researcher at MetaMask. “By working with SEAL, we can finally move faster and throw a wrench into the drainer’s infrastructure.”

SEAL’s collaborative model ensures that intelligence moves faster than attackers. Once a phishing site is identified, all participating wallets — including MetaMask, Phantom, WalletConnect, and Backpack — automatically receive the alert, allowing users to avoid scams before damage occurs.

The initiative’s ultimate goal, according to SEAL, is to extend participation to as many wallet and dApp providers as possible, creating a unified security backbone for Web3.

The timing couldn’t be more urgent. According to CertiK, phishing attacks remain the leading cause of crypto-related losses in 2025, accounting for more than $400 million in stolen funds in just the first half of the year.

Unlike traditional hacks that exploit smart contract bugs, phishing scams rely on deception — tricking users into approving malicious transactions or connecting to fake dApps. These “drainer” schemes evolve quickly, often rotating domains, migrating to offshore servers, and using cloaking tools to bypass blocklists.

Beyond phishing, overall crypto-related hacks totaled $127 million in September, down from $163 million in August, according to data from PeckShield. The month saw nearly 20 major exploits, heavily concentrated in a few large-scale incidents.

Among the most significant were UXLINK, which lost $44 million after its multisig wallet was compromised — leading to the unauthorized minting of 10 trillion tokens and a 90% price crash — and SwissBorg, which suffered a $41.5 million breach through its Solana API partner, Kiln. Both projects are currently working with exchanges, law enforcement, and white-hat hackers to recover funds and compensate affected users.

Despite the decline in overall hack volume, industry experts say phishing remains the most pervasive and preventable form of crypto theft — one that SEAL’s decentralized immune system is specifically designed to combat.

Building Trust Through Collaboration

By positioning itself at the center of this global defense initiative, SEAL is redefining how security intelligence is shared in Web3. Instead of relying on centralized authorities or slow manual reporting, SEAL’s protocol transforms security into a community-driven, real-time response system.

This approach could mark a turning point for crypto users who’ve long faced phishing scams as an unavoidable risk. SEAL said in a statement

“Security in Web3 can’t be siloed anymore. The only way to fight decentralized threats is through decentralized defense.”

With MetaMask, Phantom, and other major players backing SEAL’s mission, the industry may finally have found its most powerful weapon yet — a decentralized immune system built by the community, for the community.
