A stablecoin is a type of cryptocurrency designed to maintain a stable value by pegging it to external assets like fiat currencies (e.g., the U.S. dollar), commodities (e.g., gold), or other cryptocurrencies. Unlike volatile cryptocurrencies such as Bitcoin, stablecoins aim to provide price stability while retaining the benefits of blockchain technology.
How Do Stablecoins Work?
Stablecoins achieve stability through two primary mechanisms:
- Collateralization: Reserves of the pegged asset (e.g., USD) back the stablecoin’s value. Users can redeem the stablecoin for the underlying asset.
- Algorithmic Controls: Smart contracts automatically adjust supply (burning or minting coins) to maintain the target price (e.g., $1).
Purpose of Stablecoins
Stablecoins bridge traditional finance and crypto ecosystems by offering:
- Reduced volatility compared to other cryptocurrencies.
- Fast, low-cost transactions for payments and remittances.
- Compatibility with decentralized finance (DeFi) applications.
Types of Stablecoins
Stablecoins are categorized by their collateral type:
| Type | Collateral Example | Key Feature |
|---|---|---|
| Fiat-backed | U.S. dollar reserves | Off-chain audits for transparency |
| Crypto-backed | Ethereum (ETH) | Overcollateralized to absorb price swings |
| Commodity-backed | Gold or real estate | Tied to physical asset value |
