What is DAI?
DAI is a decentralized, crypto-collateralized stablecoin created and maintained by MakerDAO. Unlike centralized stablecoins like USDC and USDT that are backed by fiat reserves held by corporations, DAI maintains its dollar peg through overcollateralized crypto positions and algorithmic interest rates. Since launching in 2017, DAI has become a cornerstone of DeFi, with over $5 billion in circulation.
What makes DAI unique is its decentralization: no single entity can freeze, blacklist, or seize DAI tokens. The stablecoin is minted when users deposit collateral (ETH, WBTC, and other assets) into Maker Vaults and borrow DAI against it. The system requires overcollateralization (typically 150%+) to ensure DAI remains backed even during market volatility.
MakerDAO governance, controlled by MKR token holders, manages the protocol parameters including collateral types, interest rates, and the DAI Savings Rate (DSR). A native yield mechanism that lets DAI holders earn interest directly from the protocol.
Key Statistics
- Circulating Supply: $5B+ DAI in circulation
- Collateralization: 150%+ for most vaults
- DAI Savings Rate: Variable, currently ~5%
- Chains Available: Ethereum, Arbitrum, Optimism, Polygon, Base
- Collateral Types: ETH, WBTC, stETH, and many others
- Peg History: Maintained close to $1 since 2017
How DAI Works
DAI is created through a process called "minting" in Maker Vaults. Users deposit collateral assets and can borrow DAI up to a certain percentage of their collateral value. When they want to retrieve their collateral, they repay the DAI (plus any accrued stability fees) and the DAI is burned.
The peg is maintained through several mechanisms: arbitrage opportunities when DAI trades above or below $1, stability fees that discourage over-minting, and the DAI Savings Rate that creates demand. Liquidations occur when vault collateral ratios fall below requirements, with collateral auctioned to cover the debt.
For users who simply want to earn yield on DAI without managing vaults, the DAI Savings Rate (DSR) offers one-click deposits directly through MakerDAO or wrapped through various DeFi protocols.

Risk Considerations
While DAI is considered a reliable stablecoin, understand these risks:
- Collateral Risk: Extreme market crashes could affect backing
- Smart Contract Risk: MakerDAO has been audited but risk exists
- Governance Risk: MKR holder decisions affect DAI parameters
- Depeg Risk: DAI has occasionally traded slightly off-peg during stress
Frequently Asked Questions
Is DAI safe?DAI has operated since 2017 and maintained its peg through multiple market cycles. It's considered one of the most battle-tested DeFi protocols, though all crypto carries risk.
What is sDAI?sDAI (Savings DAI) is DAI deposited in the DSR, automatically earning yield. It's an ERC-4626 vault token that increases in value over time.
How does the DAI Savings Rate work?The DSR is paid from MakerDAO's stability fee revenues. Deposit DAI to earn yield; withdraw anytime. Rates are set by governance based on protocol economics.
Is DAI better than USDC?DAI offers decentralization and native yield via DSR. USDC offers regulatory clarity and corporate backing. Many DeFi users hold both for different purposes.
