What Are Stablecoins?
Stablecoins are cryptocurrencies designed to maintain a stable value by pegging their price to another asset, typically fiat currencies like the US Dollar (USD). They serve as a bridge between the volatility of crypto markets and the stability of traditional finance.1
The Stablecoin Trilemma
Three core characteristics define stablecoins:
- Stability: Maintains a consistent peg to its underlying asset.
- Capital Efficiency: Minimizes excess collateral requirements.
- Decentralization: Operates without centralized control.
Most stablecoins achieve only two of these traits, a challenge known as the stablecoin trilemma.2
Types of Stablecoins
1. Fiat-Backed Stablecoins
- Mechanism: Backed 1:1 by fiat reserves (e.g., cash, commercial paper) held in regulated institutions.
- Examples: Tether (USDT), USD Coin (USDC).
- Pros: High stability, capital efficient.
- Cons: Centralized, requiring audits for transparency.

2. Crypto-Collateralized Stablecoins
- Mechanism: Overcollateralized (e.g., 200%) with crypto assets via smart contracts.
- Examples: Dai (DAI).
- Pros: Decentralized, blockchain-native.
- Cons: Capital inefficient due to volatility buffers.
3. Algorithmic Stablecoins
- Mechanism: Uses algorithms (e.g., supply adjustments) to maintain pegs without full collateral.
- Examples: Defunct TerraUSD (UST).
- Pros: Decentralized, capital efficient.
- Cons: Prone to depegging (e.g., UST collapse in 2022).
FAQ Section
Q: Which stablecoin type is safest?
A: Fiat-backed stablecoins (e.g., USDC) are safest for stability but rely on centralization.
Q: Can algorithmic stablecoins recover from failures?
A: Only with robust redesigns addressing underlying volatility risks.
Q: Why use crypto-collateralized stablecoins?
A: For decentralized applications needing trustless, on-chain solutions.
Future of Stablecoins
Innovation continues to address the trilemma, with hybrid models and improved algorithms emerging. Stablecoins remain pivotal for payments, DeFi, and hedging crypto volatility.
