A coalition led by wallet providers MetaMask and Phantom, together with Security Alliance (SEAL), has unveiled a global real time defense network aimed at stamping out phishing attacks in the cryptocurrency ecosystem.
Quick Summary – TLDR:
- MetaMask, Phantom, WalletConnect, and Backpack join SEAL to build a real time phishing defense network.
- The system uses verifiable phishing reports to submit cryptographically validated evidence of scam sites.
- Over $400 million has been stolen through phishing attacks in 2025, pushing the industry toward collective action.
- The network allows any user to trigger phishing alerts across wallets instantly, saving funds and improving ecosystem security.
What Happened?
SEAL announced on October 21, 2025, that it has partnered with MetaMask, Phantom, WalletConnect, and Backpack to launch a global phishing defense system for crypto users. This collaboration introduces a decentralized immune system designed to block threats in real time, where participants worldwide can help prevent the next phishing attack. The launch also includes SEAL’s new verifiable phishing reports tool, which lets users prove malicious content exists on scam sites through cryptographic evidence.
We’ve joined forces to launch a global phishing defense network that can protect more users across the entire ecosystem.

Security gets stronger when we work together. 🤝 https://t.co/Ah8RuiTQ6D
Why the Move Matters?
Phishing continues to be one of the most damaging attack methods in the crypto world. According to blockchain security firm CertiK, over $400 million in digital assets have been stolen in the first half of 2025 due to phishing email incidents.
Crypto drainers, which are toolkits used by attackers to siphon funds, have evolved significantly. SEAL explains that phishing groups now use tactics like:
- Rotating landing pages to dodge blocklists.
- Offshore hosting to avoid takedowns.
- Cloaking techniques to fool automatic scanners.
Ohm Shah, a security researcher at MetaMask, said, “Drainers are a constant cat and mouse game.” He added that working with SEAL helps wallet teams apply research quickly, “effectively throwing a wrench at the drainer’s infra.”
The Collaborative Defense Approach
This partnership enables a shared defense network that reacts faster than any single provider could. Its goals include:
- Real time alerts for phishing threats.
- Automatic validation of user reports across platforms.
- Global participation with no special permissions required.
- A constantly updated database of phishing attacks.
By combining SEAL’s system with widely used wallets like MetaMask and Phantom, the network becomes a powerful force against cybercriminals targeting everyday crypto users.
How the Defense Network Works?
- A user detects a potential phishing site.
- They submit a report using SEAL’s verifiable phishing tool with cryptographic proof.
- The network automatically verifies the report and shares it with all partner wallets.
- Wallets then trigger alerts or protections immediately.
- As more users submit data, the system becomes more effective over time.
This model shifts the industry toward crowdsourced and automated defense, improving response time and reducing financial loss.
What Comes Next?
SEAL is calling on more wallets, developers, and researchers to join the effort. The more participants in the network, the faster phishing attacks can be detected and shut down. The aim is to make phishing protection standard across all major crypto platforms. This initiative also lays the foundation for building a more resilient Web3 ecosystem, where communities actively guard against threats in real time.
SQ Magazine Takeaway
I believe this is one of the most promising security collaborations the crypto industry has seen. What stands out is the real time protection and the user-driven alert system. This feels like a step forward from the usual reactive measures. The fact that any valid report can instantly protect others is a game changer. If the rest of the crypto world gets behind this and contributes data, we could finally stay one step ahead of these relentless scammers. That kind of collective defense is exactly what crypto has been missing.
