About two DeFi Products

a. Lending:

Same as banking transection, here people can invest in the lending part for the return on investment. Several interests are being provided by several product. Anyone can borrow as well from the lending pool by incurring specific interest rate. In this process, the borrower gives the interest and the lender is getting the interest in direct process. Smart contracts act as a mediator. Its is giving an opportunity to the asset holders to have some return in the form of passive income and opportunity to the borrowers as well to trade or use this asset for even higher return. This is almost similar process like centralized lending but without traditional middleman. Here, smart contract existed. Crypto loan is offered in lending of DeFi in a trustless manner without middleman called P2P lending. This lending also given to businesses and the lenders get interest in stable coins and cryptos.
I have googled for some DeFi lending and found a website where several listed DeFi Lening sites are available.

88mph
88mph is a Defi lending site which allows its users to lend their crypto assets at fixed interest rate and floating rate as well. In the picture you can see the dashboard of the page where a number of assets are available to lend at fixed interest rate. In the pool anyone can invest by watching the features like Total Deposit amount, Fixed APY, mph currency APY and other related values. All information has been specified in the website. Return will be given in MPH coin. According to available options, by connecting wallet anyone can lend some crypto for fixed or variable return and they can borrow form any pool as well.

b. Decentralized Exchange (DEX):

Here exchange operation like buy, sell, swap etc. can be done with mentioned coin for specific time without any third-party involvement. In DEX, users have full control of his/her transection. Assets can be swapped with P2P service form liquidity pool. Between the traders, there is no intermediaries, this is prime feature of DEX.

Automated Market Maker (AMM) is used by many exchanges. It is offering some kind of pool like liquidity pool which is baked by smart contract. Here automatic transection is the main purpose. In case of any disagreement between traders, Arbitrator settle the issue. DEX can be used with Decentralized wallet. Common examples of DEX are Uniswap, PancakeSwap, JustSwap, Kyber network and many more.
