A stablecoin cryptocurrency is closely related to the MakerDAO smart contract platform on the Ethereum Blockchain that allows users to own ETH with DAI.
I can say the DAI is the most fundamental part of the MakerDAO ecosystem.
Like USDT, one DAI is worth 1 USD.
Unlike USDT, DAI is secured by collateral that is cryptocurrency instead of using Fiat. This will have advantages and disadvantages.
The DAI generation and MakerDAO use the DAI price stabilization principle, users can own DAI when mortgaging cryptocurrencies through a CDP contract, and they can get their assets back when paying DAI and fees to stabilize prices touch.
DAI is one of the leading stablecoins in the crypto space with a market cap of hundreds of millions of dollars.
It has been listed on most major exchanges.
