Defi is not really vulnerable to attack, it is only due to the subjectivity of Defi projects about security, then they are only interested in the amount they have raised but are sketchy in the security mechanism. ~snip~
In other words, most defi projects are not prioritizing security on their system/mechanism? What I mean is most of them just put the security on average which as long it could be called as "safe" then it's enough..
These platforms will improve their way up to be secure with time because as with every new thing it has many requirements to perform ideally which can take a lot of time and effort that is why i say that give defi some time and we will see huge improvement. I expect defi platforms to be very secure and professional in 2 to 3 years time.
Of course they should do that, if they don't improve it then people would retake the remaining funds on them and leave it. In the worst scenario, there's a chance they would be the next dead project.
a lot of these defi projects are vulnerable to attacks because let's admit it, most of them are launched prematurely. i don't think they really look into their security diligently. as most of them are racing to get their customers and launch as soon as possible to catch the hype, they haven't dedicated enough time to secure their network.
