ETH Coding errors plague blockchain users, resulting in huge financial losses
A detailed investigation by academic researchers found that approximately US$574.8 million in cryptocurrency losses were related to user errors while using Ethereum and BNB Chain addresses. The study revealed a large number of high-risk events and highlighted key mistakes that led to digital assets being accidentally transferred to wrong or unsafe accounts.
Why is contract address risky?
Misuse of contract addresses is one of the main threats analyzed in this study conducted by well-known domestic university scholars. This error usually stems from users mistakenly believing that addresses familiar on one network can also be used on different blockchain platforms. This oversight resulted in large amounts of assets being misallocated or in trouble.
Regrettably, more than 49,000 incidents involving contract address misuse have resulted in significant losses to Ethereum and BNB. Most users are unaware of the error because they can still receive transaction confirmation even if the target address does not have the corresponding contract code.
The Uniswap V2 routing address is a typical case where a user mistakenly sent assets to an address without a contract code on the Ethereum main network, which fully illustrates the risks posed by this assumption.
To make matters worse, malicious actors exploit these errors to deploy malicious contracts on known misused addresses. This strategy allows them to steal large amounts of money from unsuspecting users.
Thousands of examples show that contract addresses used repeatedly across blockchains have become the main target of hackers, who intercept user funds by implanting malicious contracts.
Can exposed accounts cause disaster?
Yes, operational errors are not limited to contracts. Externally owned accounts also face serious threats, usually due to the public exposure of private keys, causing thieves to use these private keys to instantly empty deposits.
The introduction of EIP-7702 expands these vulnerabilities because it allows accounts to delegate permissions to smart contract execution, sometimes allowing criminals to automatically control compromised accounts. The study highlighted multiple such cases, demonstrating the urgent need for better early warning systems.
Official documents should be the only source of wallet addresses.
Users need to strictly distinguish between wallets in test environments and production environments.
Improved early warning mechanism can alert users of potentially dangerous transactions.
Real-time, integrated cryptocurrency monitoring tools are crucial to preventing losses.
In volatile cryptocurrency transactions, strong security measures and an emphasis on user education are indispensable. Upgrading wallet technology by integrating alarm functions can significantly reduce the risks caused by misuse of blockchain addresses and create a safer environment for cryptocurrency transactions.
