In the field of cryptocurrency, a smart contract called UFO has attracted widespread attention. This contract features a Pixiu design, and its biggest issue is the excessive charging of fees, achieving the goal of stable profits. However, there are many risks hidden behind this design.

A clever sleight of hand was used in the initial setup of the contract. Although an owner was set on the surface and ownership was subsequently transferred, in reality, the key _contractSender variable was not changed. This practice left hidden dangers for subsequent operations.

It is even more concerning that there are multiple potential vulnerabilities in the contract code that could be exploited. The most notable of these is that, under certain conditions, the contract can transfer funds to the _contractSender address without justification. This design significantly increases the risk of users' funds being improperly transferred.

Overall, the design of the UFO contract reflects the practices of certain developers who are willing to sacrifice user rights in pursuit of profit. For potential investors and users, it is crucial to have a deep understanding of the specific implementation of smart contracts and the potential risks involved. Conducting comprehensive due diligence and technical assessments is essential before participating in any cryptocurrency project.
