# Week 2 EIF 3.0
Week2 started with having a talk with my EIF mentor : Gautham sir, Founder of Polynomial.fi </br>
He mentioned some key points for the projects : </br>
-> The code is the easy part, what's hard in defi is to figure out the mechanics. </br>
-> In case of extreme market conditions, permissionless defi protocols like my idea, fail around because of the indeterministic ETH price going out of the thought-of bounds.
The leverage then falls to lower boundaries. In order to cope up with these failures, it's important to figure out the REBALANCING MECHANISM ( this is where I get stuck for long)
</br>-> Euler finance offers 0% fees flashloan so that's an obvious advantage over AAVE flashloans which I was using.
