Decentralized finance, which is commonly referred to as DeFi, has revolutionized the way money, saving, and credit are viewed in a relatively brief period. DeFi is unique in that it does not have middlemen, and it uses blockchain and smart contracts to conduct financial dealings. The most thrilling part of DeFi is likely lending and borrowing, where people lend their cryptocurrency holdings for returns or borrow a loan by offering digital collateral. Such currencies as Bitcoin and Ethereum, though, are very volatile, therefore less appropriate for stable money contracts. Stablecoins come into play as a fulcrum in between volatility and stability.
