Hoskinson flags Binance sweeper code as EIP-7702 debate grows

Cardano founder Charles Hoskinson has warned about “seriously dangerous code” while sharing an analysis that blames Ethereum’s EIP-7702 delegation feature for helping attackers rapidly empty a Binance hot wallet. Summary Hoskinson shared a technical breakdown alleging the sweeper was built specifically for Binance’s wallet infrastructure. CyberSatoshi claimed 50 signed authorizations helped the attacker target the hot wallet’s changing transaction nonce. The analysis acknowledged that private-key control or unrestricted signing access was needed to authorize delegation. Ethereum’s specification warns that delegated code receives unrestricted account access and requires careful security checks. In his X post, Hoskinson wrote, “Careful, there is some seriously dangerous code out there,” above a breakdown published by CyberSatoshi.

Hoskinson’s accompanying message did not identify a specific protocol flaw or explain which part of the analysis he endorsed. CyberSatoshi’s account places two security questions alongside each oth...
