On April 14th, it was reported that Yearn Finance posted on Twitter the progress of the investigation into the attack, stating that as previously stated, the root cause of the attack on Yearn was a vulnerability left in the iEarn USDT (yUSDT) token contract. This vulnerability exists in multiple versions and leads to multiple Curve pools (y, busd, pax) being exploited and exhausted. The liquidity providers who deposit LP tokens into downstream protocols are still affected, including users who encapsulate the Yearn v2 vault (2) and the old version v1 vault (2) of these affected LPs. In previous tweets, Year stated that the current version of Year v2 Vaults is not affected.

Introduction
On April 14th, Yearn Finance reported on Twitter about the progress of their investigation into the recent attack on their system.

In this article, we will delve deeper into the issue to get a better understanding of what happened and how it has affected Yearn Finance and its users.
What is Yearn Finance?
Before diving into the details, let’s first understand what Yearn Finance is. Yearn Finance is a decentralized finance (DeFi) platform that allows users to earn yield on their cryptocurrency assets. The platform helps users access different yield farming strategies, providing them with the best returns on their investments. The main objective of Yearn Finance is to simplify DeFi investments and make them accessible for everyone.
The Vulnerability in iEarn USDT (yUSDT) Token Contract
As stated by Yearn Finance, the root cause of the attack was a vulnerability left in the iEarn USDT (yUSDT) token contract, and this vulnerability exists in multiple versions. This has led to multiple Curve pools (y, busd, pax) being exploited and exhausted. As a result, the liquidity providers who deposit LP tokens into downstream protocols are still affected, including users who encapsulate the Yearn v2 vault (2) and the old version v1 vault (2) of these affected LPs.
Impact on Yearn Finance and Its Users
The attack has had a significant impact on Yearn Finance and its users. Yearn Finance has suffered a loss of around $11 million in its DAI vault, which has been drained due to the attack. Moreover, the vulnerability in the iEarn USDT (yUSDT) token contract has also affected the users of the platform. Several users have lost their funds due to the attack, which has sparked concerns regarding the security of the DeFi platforms.
Security of DeFi Platforms
The recent attack on Yearn Finance has raised several important questions regarding the security of DeFi platforms. DeFi platforms provide users with a high level of anonymity and decentralization, which makes them attractive for investors. However, due to the anonymity and decentralization, DeFi platforms are more vulnerable to attacks, which can lead to significant losses.
Conclusion
In conclusion, the vulnerability left in the iEarn USDT (yUSDT) token contract has caused significant damage to Yearn Finance and its users. The attack not only resulted in the loss of millions of dollars but also raised serious concerns regarding the security of DeFi platforms.

Why doesn’t Bitcoin have customer service? Editor’s note: This article is from Bitcoin (ID: Bitcoin), authored by Bitcoin, and reprinted by the Daily Planet with authorization A few days ago, a netizen asked me why I don’t have customer service? The answer to saying, ‘What’s the matter?’ is’ Are you looking for customer service? ‘? Actually, this issue is very complex, but it is also worth considering 1. If the customer calls to inquire if there are any issues, they will provide an explanation; If it’s not that simple, if they can’t reply, it means they can’t solve it anymore; If you have not contacted this person in charge or anyone else, you will only be informed that ‘we have reached the service stage’ 2.
