This stability enables more predictable payments and savings, making crypto more practical for everyday use.
Types of Stablecoin
Stablecoins are classified based on how they maintain their stability. The main types include:
- Fiat-Backed Stablecoins – Pegged to traditional currencies like the U.S. dollar (e.g., USDT, USDC). They are backed by reserves held in banks.
- Crypto-Backed Stablecoins – Backed by other cryptocurrencies (e.g., DAI). They use over-collateralization and smart contracts to maintain stability.
- Commodity-Backed Stablecoins – Pegged to physical assets like gold or oil (e.g., PAXG, DGX). Their value depends on the underlying commodity.
- Algorithmic Stablecoins – Use algorithms and smart contracts to control supply and demand (e.g., UST, FRAX). They rely on mechanisms rather than collateral.
Each type has its own benefits and risks, depending on how it maintains stability.
