Learn how USDC, DAI, and USDT maintain their dollar peg

⚖️ Stablecoin Peg Mechanics

Stablecoins aim to maintain a stable value (usually $1.00) despite crypto market volatility. Understanding how different types maintain their peg is crucial for assessing risk and choosing the right stablecoin for your needs.

Why Stablecoins Matter

💱

Trading & Liquidity

Stablecoins serve as the primary trading pair for crypto assets. They allow traders to exit volatile positions without converting back to fiat, providing crucial liquidity across all DeFi protocols.

💸

Payments & Transfers

Enable fast, cheap cross-border payments with price certainty. No more worrying about BTC dropping 10% while your transaction confirms. Instant settlement with predictable value.

🏦

DeFi Building Block

Foundation of lending, borrowing, and yield farming. Stablecoins allow you to earn yield on "cash-like" assets without exposure to crypto volatility. Critical for protocol stability.

🌍

Financial Access

Provide dollar access to anyone with internet, bypassing banking systems. Crucial in countries with currency instability or restricted banking access. True financial inclusion.

💡

The Stablecoin Trilemma

Like blockchain's trilemma, stablecoins face three competing goals:

  • 1.Price Stability: Maintain tight peg to $1.00 (±0.1%)
  • 2.Decentralization: No single point of failure or control
  • 3.Capital Efficiency: Minimal collateral requirements

Most stablecoins optimize for 2 of 3: USDC (stability + efficiency), DAI (stability + decentralization), algorithmic attempts (efficiency + decentralization) often fail on stability.
