DAI is a decentralized stablecoin pegged to the US dollar, serving as the backbone of MakerDAO's lending ecosystem. As one of Ethereum's most established dApps, MakerDAO enables users to generate DAI against crypto collateral while minimizing volatility—a hallmark of stablecoin design.
How DAI Works: Collateralization and Stability Mechanisms
Multi-Collateral DAI (MCD) System
Launched in 2018, Multi-Collateral Dai replaced Single-Collateral Dai (SAI) with these core features:
- Collateral Diversity: Accepts ETH and approved ERC-20 tokens (e.g., USDC) via Maker Vaults
- Overcollateralization: Requires collateral value exceeding borrowed DAI amounts (120%-150% ratios)
- Liquidation Protection: Automated processes maintain system solvency during price drops

The Dual-Token Model
- DAI Stablecoin: Algorithmically stabilized soft-pegged asset
MKR Governance Token:
- ERC-20 asset controlling protocol decisions
- 1 MKR = 1 vote for collateral approvals
- Supply adjusts automatically to maintain DAI's peg

Frequently Asked Questions
What makes DAI different from other stablecoins?
Unlike centralized alternatives (USDT, USDC), DAI maintains decentralization through Ethereum smart contracts and community governance via MKR tokens.
How is DAI's value maintained?
Through continuous collateral audits, liquidation mechanisms, and MKR token adjustments that automatically burn/supply tokens to preserve the $1 peg.
Can DAI lose its peg?
Temporary deviations occur (historically ±3%), but the system incentivizes arbitrageurs to restore equilibrium through collateralized debt positions.
Where can I use DAI?
Most DeFi platforms (Compound, Aave), crypto exchanges (OKX, Binance), and as payment at 4000+ merchants via payment processors.
Is DAI a good store of value?
For short-term holdings, its stability outperforms volatile cryptos. Long-term, inflation risk exists as USD purchasing power changes.
What are the risks of using DAI?
Smart contract vulnerabilities, collateral depreciation, and protocol governance failures could impact stability—though MakerDAO maintains insurance funds.
