The problem Praxis Finance solves

Opening up leveraged positions on top of gold standard liquidity pools like AAVE,COMPOUND remains one of the top methods in the investment strategy of crypto traders. Leveraged Positions allows trader to gain exposure to (leveraged times) the price movements. However, it also comes with its associated risks as the performance of a leveraged token really depends on the market being trendy or extreme.
Onchain derivatives are necessary to counter the derivatives built over CEX. Onchain perps are built over liquidity pools as limit orderbooks on chains is tough. We need users to be able to trader perps onchain in a deep, trustable, transparent liquidity pool.
Building derivatives on golden standard pools like save are bound to happen. Praxis is a step in that direction.

Challenges I ran into

The one challenge I really ran into was finding the optimum rebalancing mechanism because it really depends on the market conditions as to how good a leveraged token will perform. Looked over various protocols to find more information on rebalancing mechanisms.
Also being a smart contract dev for the past few months, I really had left the touch of web3 development. So had to do some small projects in Next.js and wagmi in order to revive the things up.
Also, I had to read a lot of articles related to tokenomics in order to get ahead in the foundational knowledge.
