Depletion of liquidity and loss of funds: A closer look at Merlin’s recent hack

On April 26th, it was reported that Bobbie, the founder of Web3 Knowledge Graph Protocol 0xScope, tweeted that the liquidity of zkSync ecological DEX Merlin was depleted, and hackers stole $1.82 million in funds and bridged it to Ethereum.

ZkSync Ecological DEX Merlin Liquidity Exhaustion

The decentralized exchange (DEX) community has been left in shock following the recent security breach that hit Merlin, a well-known DEX built on the zkSync scaling solution. According to Bobbie, the founder of Web3 Knowledge Graph Protocol 0xScope, Liquidity of DEX Merlin was depleted, and hackers stole $1.82 million in funds before bridging it to Ethereum. This attack has raised significant concerns about the security of DEXs and the need for stronger measures to protect users and assets.

What Led to the Depletion of Liquidity and Loss of Funds in Merlin?

Merlin achieved tremendous success in its short history by offering a fast, secure, and cost-effective trading experience to its users. It boasts of an intuitive user interface, tight security, and a broad selection of ERC20 tokens. However, on April 26th, an unknown attacker or group of attackers targeted the DEX’s liquidity, causing significant damage. This hacker exploited a vulnerability in the liquidity pool smart contract and withdrew more than 4000 ETH (worth $9.34 million) and more than 1.8 million USDC (worth $1.82 million).
The attacker then converted these funds into a variety of other cryptocurrencies and withdrew them from the liquidity pool, leaving Merlin with significantly depleted liquidity. The hacker was also able to bridge a portion of the stolen funds to Ethereum, which raises concerns about the security of cross-chain operations.

What are the Implications of Merlin’s Recent Hack?

The recent attack on Merlin highlights the need for more robust security measures in the DeFi space, particularly in DEXs. One of the primary reasons that hackers target DEXs is the high liquidity that they offer. Unlike centralized exchanges, which hold users’ assets in a centralized manner, DEXs require users to deposit funds into smart contracts that work as liquidity pools. Since these pools are decentralized, they are more accessible to attackers who can gain unauthorized access to the funds.
Moreover, unlike centralized exchanges that can employ anti-money laundering and Know Your Customer policies, DEXs lack regulatory oversight, making them attractive targets for fraudsters. As a result, users need to be vigilant and avoid exposing themselves to unnecessary risk.

What is the Way Forward for Merlin and the DeFi Industry?

Merlin and other DEXs need to take strong measures to ensure that their liquidity pools remain secure. One way to do this is by enhancing the security infrastructure of their smart contracts. For instance, it may be necessary to conduct periodic auditing of these contracts to identify potential vulnerabilities and address them before attackers can exploit them.
Moreover, awareness campaigns can help users become more vigilant while trading on DEXs. They should exercise caution when depositing funds into liquidity pools and should only invest what they can afford to lose. Users who notice any suspicious activity on DEXs should report the same promptly to the relevant authorities.

Conclusion

The recent hack on Merlin is a wake-up call for DEXs and the DeFi industry to take security seriously. While DEXs offer users unparalleled freedom, anonymity, and accessibility, they also expose them to unprecedented risks. Therefore, it is imperative for DEXs to enhance their security infrastructure and for users to be more vigilant while trading on these platforms.

FAQs

Is it safe to use decentralized exchanges such as Merlin?

While DEXs offer users greater privacy and control over their funds, they are not a foolproof solution for trading in the DeFi space. Users should ensure that they remain vigilant and keep their private keys secure to avoid falling prey to hackers.

Can DEXs prevent all hacks and vulnerabilities?

No, DEXs can’t prevent all hacks and vulnerabilities; however, DEXs can take measures to enhance their security measures, such as auditing their contracts regularly, implementing robust monitoring systems, and collaborating with other DEXs and security experts to identify and address weaknesses.

What are the implications of security breaches on the DeFi industry?

Security breaches can have significant implications for the DeFi industry, especially in terms of user confidence and regulatory oversight. It is, therefore, imperative for industry players to enhance their security infrastructure and collaborate with regulators to ensure that users’ funds and personal data remain protected.
