Exchange Kava

Kava is a cross-chain DeFi platform for lending USDX stablecoins. Platform users can borrow stablecoins while depositing their collateral and purchasing a variety of other digital assets to start profiting from it. It was launched in 2019. As the official website says, Kava aspires to make democratized financial services available for everyone. 

Kava DeFi hub is functioning as a decentralized bank of digital assets providing users with access not only to stablecoins, but also other financial services such as synthetics and derivatives. To use the assets across different chains they need to be wrapped as BEP-20 tokens. Also, users can mint their USDX stablecoins and then contribute it to the platform's money market (HARD Protocol) and thus earn APY while the collateral is secured by the network. 

The project is built on the Cosmos blockchain and uses a collateralized debt position system (CDP) to ensure that stablecoin loans are sufficiently collateralized. If the borrower couldn’t keep their collateral higher than a defined threshold limit, the Kava liquidator module will take collateral from the failed CDPs and redirect them to the auction. 

The platform is fueled by utility Kava tokens which also grant the governance of the platform and could be used as a reserve currency if the system is undercollateralized. Kava is an inflationary token with a total supply of 111.5 million tokens that grows every year from 3% to 20% depending on the staking proportion. The current circulating supply is 91 million coins.
