MetaMask, Major Crypto Wallets Join Global Defense Network Following $400M Loss From Phishing Attacks

Crypto Wallets

Leading providers, including , , WalletConnect, and Backpack, have partnered with the Security Alliance (SEAL) to launch a global, real-time phishing defense network, following reports of over $400 million in cryptocurrency stolen during phishing incidents in the first half of 2025. 

“We’ve joined forces to launch a global phishing defense network that can protect more users across the entire ecosystem,” said the on Wednesday.

The collaboration marks a significant shift in wallet-provider strategy, signalling that combating threat actors may no longer be an individual task but rather a coordinated global effort. The network is designed to enable any verified user or researcher to submit phishing site reports, which are then validated and instantly shared across all participating crypto wallets, effectively creating a decentralized immune system for crypto security.

Why Are Crypto Wallets Forming a Defense Network? 

According to from blockchain security firms, phishing attacks have surged in 2025, with over $400 million lost through drainers and scam sites targeting self-custody crypto wallets and Web3 users. Wallet providers report that attackers have intensified their tactics, including rapidly rotating phishing landing pages, utilizing offshore hosting, and employing cloaking methods to evade blocklists and automated scanners.

MetaMask’s security research team described the typical threat vector as a fake job offer or project invite targeted at , which leads to a malicious script executing a wallet connection and draining funds. The new defence network aims to reduce the window of exposure by speeding up detection and response. 

The defence framework is designed to perform three key functions, including the verification of phishing reports, real-time alert broadcasting, and shared infrastructure across wallets. By pooling intelligence, the consortium of can react more swiftly and comprehensively than individual providers acting alone. This will reduce duplication and improve overall ecosystem resilience. 

Crypto Wallet Security and Adoption Get A Major Boost 

For the broader crypto ecosystem, especially as self-custody and  adoption rise, this defence initiative represents a pivot point in how security is managed: from isolated product-level protections to coordinated, network-wide intelligence sharing.

Phishing remains one of the most persistent threats in the cryptocurrency industry, with losses exceeding $400 million having increasingly eroded user trust. By publicly committing to this model, wallet providers are signalling to both users and institutions that they take security at scale seriously, which may bolster confidence among risk-sensitive investors and custodians.

Moreover, the initiative may reduce friction for new users entering the crypto space. When barriers such as scam risk diminish, retail and institutional participation become more viable. In turn, that could accelerate the on-ramp to and integration into mainstream financial services.

The alliance between major crypto wallets and SEAL to create a real-time, global phishing defence network reflects the maturation of Web3 security. With over $400 million lost to phishing this year, the coordinated approach may redefine how the industry protects users and builds trust — an essential foundation if digital assets are to scale from niche trading into mainstream finance.
