Why stable coins in Defi

Cryptocurrencies are well known for their high volatility, they can change in price easily, in order to protect user funds from this fluctuation in market price, Stablecoins were created.

What is a Stable Coin?

A stablecoin is a type of cryptocurrency that is pegged to other stable assets like US Dollars.

Types of some popular stablecoins

2) USD

How are Stablecoins maintained?

Stablecoins are maintained by 3 major methods.

1) Fiat or commodity-backed stablecoins.

In this method, all stablecoins in circulation are backed by an equivalent of the value in fiat currency or cash equivalents, 1 USD equivalent is held on reserve in U.S bank accounts owned by the issuer, and monthly these reserves are audited.
for example USDT

Tether is a centralized, fiat-collateralized stablecoin.

2) Cryptocurrency-backed stablecoins.

This method is also known as The decentralized method

3) Algorithm-backed statblecoins

These are stablecoins pegged through smart contracts that automatically execute to manipulate the circulating supply depending on market conditions.
