# On April 5th, Sentient Loses $1 Million Due to Balancer’s Limitations
Sentient, an unlicensed partial mortgage loan agreement, was hacked on the Arbitrum network on April 5th. According to PeckShield monitoring, the hack resulted in a loss of about $1 million. The root cause of this hack was due to the read-only and reentrant nature of Balancer.

Introduction

Sentient is a partial mortgage loan agreement that allows investors to fund a portion of a borrower’s mortgage. On the other hand, Balancer is an automated market maker that facilitates trading of cryptocurrency assets.

What Happened on April 5th

On April 5th, Sentient was hacked due to vulnerabilities in Balancer. As per the reports from PeckShield, a smart contract was used to manipulate the liquidity pools on Balancer. This caused the value of the tokens to differ between the pools and enabled the attacker to buy low and sell high.
As a result, Sentient suffered a loss of about $1 million. Investigations revealed that the attacker had been planning this hack for some time and had multiple wallets and addresses.

Balancer and its Limitations

Balancer, like any decentralized platform, has its own limitations. Balancer is read-only and reentrant in nature, which means that one contract can call the same contract simultaneously. This limitation enables hackers to manipulate the system to their advantage.

Analysis of the Hack

This attack on Sentient was not the first of its kind. There have been multiple incidents of cyber attacks in the cryptocurrency world. One of the main factors contributing to these attacks is the complexity of the smart contracts.
These smart contracts are the backbone of the entire cryptocurrency system. However, when something goes wrong, there is no central authority to fix it. Hackers take advantage of such bugs and vulnerabilities in smart contracts.

Preventing Similar Incidents

Similar incidents can be prevented by conducting thorough code reviews, identifying vulnerabilities, and auditing the code. Open-source code reviews are essential in identifying bugs and vulnerabilities in smart contracts.
Furthermore, it is also essential for developers to keep track of the latest developments and updates to ensure the safety of the system. Companies and individuals must also keep up with security protocols to prevent any future attacks.

Conclusion

To conclude, the hack on Sentient due to Balancer’s limitations highlights the importance of the security of smart contracts. The cryptocurrency world is a vast and expanding space, and the safety of the system is crucial. It is up to the developers and companies to ensure the safety of their platform adequately.
