There are many decentralized finance chains and platforms out there. And it can be pretty tough to find out what works and what does not. And only way to find that out is through reviews, experience of your own self and also your understanding of how the DeFi works. Most of such solutions have a lot of things blended in like DeFi, lending protocols and also the liquidity systems too.
I recently came across one such protocol named Kleverchain which works in the DeFi space. They are in the POS systems so the chain is more easier to work with compared to proof of work chains out there.

Kleverchain is a proof of stake based blockchain. This blockchain is intended for the staking, DeFi and smart contracts designed for the wallet, smart contracts and other usage scenarios. This chain would be extended it's product and features through the fintech smart contracts and the features which would be in the lending and the borrowing protocols and the smart contracts.
KLV coin is designed for the DeFi purpose. And many apps designed around this coin which would be given when the liquidity is added in the pool. So the KLV finds it's use case in such scenarios for the lending and the borrowing. The way such type of the protocols and the smart contracts work, we have to check out how the borrowing and staking platforms work for the design of the right kind of apps in Fintech space. I think only part remains which is regulation and the policies to govern the fintech side of such DeFi.
