EIP-7702 Transactions Explode After Pectra Update: Innovation or Phishing Trap?

Ethereum's recent Pectra update boosts EIP-7702 transactions, but also warns of new phishing risks in wallets like MetaMask.

The Ethereum revolution has gained new momentum with the Pectra upgrade, which catapults transactions under the EIP-7702 standard from a handful to a staggering number of nearly a thousand per day. This advancement not only improves the features of digital wallets, facilitating transactions without address changes, but also promises much more fluid and secure interaction for users within the vast world of DeFi and Web3.

However, behind this technological evolution, disturbing shadows emerge that are now capturing the attention of the blockchain community: The latent phishing risks associated with these grouped transactions, which, while simplifying the process, can open the door to more sophisticated and rapid attacks.

The Pectra update and its impact on EIP-7702 transactions

Pectra has arrived like a breath of fresh air for Ethereum, giving the network a significant leap in capacity and usability. Before this update, EIP-7702 transactions were rare, amounting to only a few instances per day. Today, the number is growing exponentially, reaching almost a thousand per day, a clear reflection of the acceptance and usefulness that this improvement offers to users. as noted by the Everstake platform.

And EIP-7702 stands out for allowing traditional accounts, known as externally owned accounts (EOA), perform action groupings, use sponsored gas, and add authentication methods with access keys, turning basic wallets into much more powerful tools without the need to migrate to complex smart contracts.

This progress not only improves the user experience by making transactions simpler and faster, but also opens the door to new use cases in the decentralized economy, such as more convenient access to DeFi applications and other Web3 services that require multiple and bulk interactions. By preventing address changes, account integrity and traceability are maintained, facilitating audits and improving security from the perspective of the average user.

Phishing risks increased by simplification in grouped transactions

However, this comfort brings with it a dark side that cannot be ignored. According to security experts, the way EIP-7702 transactions bundle multiple transactions into a single action can be a double-edged sword. The simplified experience allows less experienced users to approve complex packages without fully understanding what permissions they are granting, making it easier for cybercriminals to execute phishing attacks with unprecedented speed and effectiveness.

For example, a scammer could design a malicious web page that mimics the interface of a legitimate platform, asking the user to approve a batch transaction. Because popular wallets like Dappradar The display of advanced details may be disabled by default, and the user only sees a generic warning and inadvertently authorizes their ERC-20 token balance or even NFTs to be silently transferred to addresses controlled by the attacker. This strategy eliminates the need for multiple pop-ups or consecutive confirmations, reducing suspicion and speeding up the fund extraction process.

This phishing method is especially dangerous because it not only relies on traditional key or data theft, but also exploits trust and the lack of detailed information in the user interface. The lack of additional friction in approving multiple permissions allows asset drain to occur in a matter of seconds, complicating early detection and potential recovery.

How to protect yourself in a grouped transaction environment?

Hence, to minimize the risks, It is essential to adopt best practices that help distinguish which transactions should be authorized and which could be malicious. This includes always carefully checking requested permissions, looking for warning signs in the website's URL and domain, and responsibly managing security settings in wallet applications.

Another key focus lies in the development and deployment of automated tools such as the one created by wintermute, called «CrimeEnjoyor", which alerts users to potentially malicious Ethereum contracts attempting to drain funds using automated techniques. These types of initiatives combine community intelligence with technology to detect suspicious patterns and prevent significant losses, a necessary step in the evolution of security within the ecosystem.

Furthermore, understanding the inner workings of bundled transactions can make all the difference. Knowing that a single click could bundle permissions for multiple tokens and NFTs, and that this action can be irreversible in many cases, encourages a more cautious and critical approach to each interaction.

Future and balance between innovation and security in Ethereum

The Pectra upgrade represents a technological milestone that brings Ethereum closer to mass adoption, with tangible improvements in user experience and network efficiency. However, this evolution must be accompanied by a strengthened security culture and ongoing education for users, who are the first line of defense against phishing and fraud threats.

The transactions bundled under EIP-7702 are just the beginning of a path toward a more powerful platform, but the balance between usability and security must be carefully managed. Collaboration between developers, security experts, users, and platforms like Bit2Me, which offer trusted environments for managing digital assets, is critical to building a secure and sustainable ecosystem.

In conclusion, the speed of adoption and the growing volume of transactions thanks to Pectra should not overshadow the essential attention required to prevent associated risks. If users understand the technical mechanisms and maintain a critical attitude toward each approval request, they can take full advantage of the benefits of this update without compromising their assets.

Investing in cryptoassets is not fully regulated, may not be suitable for retail investors due to high volatility and there is a risk of losing all invested amounts.
