SlowMist Cosine: Beware of EIP-7702 Phishing Batch Transaction Traps

According to ChainCatcher, SlowMist founder Cosine reposted a security alert from Scam Sniffer, stating that another user lost approximately $1.54 million today due to signing an EIP-7702 phishing batch transaction, involving ETH, BTC, and several other tokens staked on Ethereum.

This phishing method exploits EIP-7702 by delegating the user's EOA address authorization to MetaMask: EIP-7702 Delegator, and then uses its contract calls to complete subsequent token transfers. This technique has already been industrialized by major phishing groups, and falling for such a transaction could result in the loss of an entire account's assets.

Cosine reminds users to verify the authenticity of websites and links before confirming any transactions to prevent fraud.
