The problem ProFi solves

We made a platform for new users to help make profitable
decisions in the crypto market.
It uses an algorithm that gives a score to any ERC-20 token based
on many parameters.
The algorithm is deployed on different chains, and the data is
updated after a certain period.
Data is also available on decentralized storage like IPFS,
Tableland, etc., which helps maintain trust and transparency of
the platform.

Challenges I ran into

We faced problems in data collection. We couldn't find a subgraph for it so we had to create & deploy our own.
We also faced problems in analysing the parameters & assigning appropriate weights to them.
Backtesting took around 1 complete week. That took a lot of sweat!
