- EIP-7702 exploitation leads to $1.5M loss for Ethereum investor.
- 90% of delegations link to malicious contracts, warns security firm.
- No direct commentary from Ethereum’s core developers on the incident.
An Ethereum investor lost $1.5 million in late August 2025 due to a phishing attack exploiting the EIP-7702 mechanism through a fake Telegram prompt.
The incident highlights vulnerabilities in Ethereum’s EIP-7702, urging for enhanced security protocols in wallet interfaces to prevent future thefts.
Financial Loss and Security Concerns
In August 2025, an Ethereum investor lost $1.5 million due to a scam linked to the EIP-7702 delegation mechanism. This incident underscores vulnerabilities in Ethereum’s protocol following the Pectra upgrade, leaving decentralized finance users exposed to potential risks.
The attacker remains unidentified, and no official statements from Ethereum leadership have been issued. Crypto security authorities emphasize that malicious contract delegation presents significant risks under the new EIP-7702, urging users to carefully verify transaction details before approval.
The immediate impact was financial loss for a single Ethereum user, with broader systemic stability unaffected. The theft involved ETH and ERC-20 tokens, with on-chain activity confirming rapid liquidation using decentralized exchanges such as Uniswap.
Despite this being a single-user event, the broader concern is user education gaps within the Ethereum community. Developers and security firms highlight the urgency for improved wallet-side warnings and sophisticated user interfaces to prevent similar exploits. “90%+ of EIP-7702 delegations link to malicious contracts, urging users to verify transaction domains and reject ambiguous approvals.” – Scam Sniffer, Security Firm, source
Phishing attacks exploiting wallet signatures are increasingly prevalent, with similar past incidents documented. Experts call for enhanced user awareness and more stringent protective measures to mitigate risks, focusing on evolving threat landscapes.
Potential outcomes include advancements in security protocols and regulatory scrutiny. Historical trends suggest market balance remains stable despite isolated thefts. Developers may prioritize wallet updates and community education to safeguard Ethereum’s network integrity.
