The evolution of Ethereum blockchain has always been a double -edged sword. While innovations like EIP-7702 promise to democratize intelligent contract features for daily users, they also open Pandora’s risk boxes. In May 2025, a phishing scam of $ 1.54 million revealed the vulnerabilities of this upgrade, serving as a striking warning for retail and institutional investors. As the abstraction capacities of the Ethereum account ripen, the cryptographic ecosystem must attack a new breed of threats which exploit the very functionalities designed to improve the user experience.
The EIP-7702 mechanism: a Trojan horse for phishing?
The EIP-7702, introduced into the Pectra Hardfork, allows accounts belonging to the outside (EOAS) to temporarily delegate the executive authority to intelligent contracts. This allows features such as lots transactions, gas sponsorship and session keys without obliging users to migrate to complete additional wallets. Technically, the upgrade introduces a delegation designator (0xef0100 || address
) which transports EOA transactions to a specified contract. Although this rationalizes operations, it also creates a critical attack surface: users can unknowingly authorize malicious contracts to perform arbitrary actions in a single transaction.
The $ 1.54 million scam illustrates this risk. A victim, attracted by a phishing site imitating Uniswap, approved a transaction by dot disguised in exchange for token. The malicious contract, taking advantage of the EIP-7702, has executed a series of hidden tokens transfers and NFT approvals, draining the portfolio in seconds. The attack exploited the execution model by lots, which bypassing the user invites step by step by traditional steps, and the delegation mechanism, which enabled the malicious contract to act as EOA itself.
The landscape of growing threats
Wintermute and Goplus Security report that more than 90% of EIP-7702 delegations observed on chain are linked to malicious contracts. These “sweetening” contracts automatize the drainage of compromised wallets, often punching the stolen assets at Ethereum MAINNET via protocols such as the relay protocol. Phishing groups such as #Infernodrainer and #PinkDrainer have armed EIP-7702, deploying phishing sites that imitate the Defi Plates of confidence. In a case, a victim lost $ 146,000 after approving a transaction that seemed to be a routine swap but rather launched a sweeping logic contract.
The risks are amplified by the novelty of the EIP-7702. Many users do not know the implications of the delegation of the executive authority, and even sophisticated investors can ignore the complexity of lots transactions. The Cry Crypto Working Group has not yet responded to these specific risks, leaving frameworks of compliance with the rhythm of innovation.
Strategic safety and compliance measures
For investors, the lesson is clear: the advantages of EIP-7702 are accompanied by increased responsibilities. Here are steps originally to mitigate the risks:
-
Check intelligent contracts before the delegation
Delegate only to Audité trusted contracts. Tools such as Sniffer scam and verification of Etherscan’s contract can help identify the malicious code. -
Limit the scope of the delegation
Restress delegations to specific and essential contracts and revoke authorizations when they are no longer necessary. Avoid granting wide or unlimited approvals. -
Use portfolios with EIP-7702 guarantees
Portfolios like Metamask restrict the delegation to white list contracts and apply the signature in the application. Avoid portfolios that allow an arbitrary delegation. -
Monitor the authorizations and delegations of tokens
Regularly audit approvals and tokens delegations using tools such as tokens or challenge approvals. -
Avoid inherited wallets
Pre-EIP-7702 portfolios lack storage collision protections and are vulnerable to the first cycle. -
Adopt multilayer compliance tools
Institutions must integrate the fraud detection systems in real time, end-to-end encryption and multi-factory authentication to protect themselves against EIP-7702 exploits.
Investment implications and the upcoming road
The EIP-7702 represents a central step towards the complete abstraction of the Ethereum account, but its adoption must be balanced with caution. For investors, the key is to treat the EIP-7702 not as a convenience but as a passive requiring active management. The DEFI space evolves quickly and those who fail to adapt their security practices are likely to become collateral damage in a war between innovation and exploitation.
As the Ethereum ecosystem matches, the burden will pass developers to users and institutions to apply solid security. The scam of $ 1.54 million is not an anomaly – it is a warning sign of a new era where technical sophistication meets social engineering. For investors, the path to follow lies in education, vigilance and the desire to embrace tools that transform the power of EIP-7702 into a shield rather than a weapon.
In the end, the cryptography market will reward those who will sail these pension risks. The question is not whether the EIP-7702 will succeed, but if investors are ready to secure their positions in a landscape where each upgrade brings both opportunity and danger.
