Introduction to Stablecoins
Stablecoins serve as the liquidity backbone of the crypto ecosystem, bridging traditional finance and decentralized finance (DeFi). These price-stable digital assets peg their value to external references like fiat currencies, commodities, or algorithms, enabling efficient payments, cross-border transfers, and DeFi participation while minimizing volatility exposure.
Stablecoin Classification
1. Fiat-Collateralized Stablecoins
- Centralized issuance with 1:1 fiat reserves
- Examples: USDT, USDC
- Requires regular audits for transparency
2. Crypto-Collateralized Stablecoins
- Decentralized via overcollateralization
- Example: DAI (now rebranded as USDS)
- Operates through smart contracts
3. Algorithmic Stablecoins
- Supply-adjusted stabilization mechanisms
- Examples: FRAX, former UST
- No direct asset backing required
4. Commodity-Backed Stablecoins
- Pegged to physical assets like gold
- Examples: PAXG, XAUT
