Academic research’s warning has come to pass: 63% of EIP-7702 authorizations involve malicious contracts.
57 minutes ago
A 2026 empirical study from USENIX Security found that roughly 63% of around 3.66 million early EIP-7702 authorization transactions across seven blockchains were linked to malicious contracts, with confirmed losses exceeding $2.3 million and 924 malicious contracts identified. Most attacks tricked users via phishing to sign authorizations, delegating their wallets to token-sweeping contracts. This study directly contrasts with today’s abnormal Binance hot wallet outflow incident. On-chain analysis shows attackers used EIP-7702 authorizations signed via Binance 14 and other hot wallets to delegate to pre-deployed malicious sweeper contracts, then bulk transferred assets within minutes (multi-source estimates put the total at billions of dollars, with Tether, Circle and others freezing some stablecoins). Whether due to private key leaks or signature system abuse, this incident confirms the study’s core risk: once a valid authorization signature is obtained, EIP-7702 grants attackers persistent execution control over accounts until revoked.
