Overview
- DAI is an Ethereum-based stablecoin pegged to the US dollar.
- Its value is stabilized through autonomous smart contracts, eliminating the need for centralized control.
- Integral to MakerDAO’s lending ecosystem, DAI is created when users borrow and destroyed when loans are repaid.
Unlike other stablecoins (e.g., Tether, USDC), DAI is fully decentralized, relying on algorithmic mechanisms rather than third-party audits.
What Is DAI?
DAI is an ERC20 token on Ethereum, designed to maintain a 1:1 peg with the USD. Key features:
- Decentralized: No single entity controls its supply.
- Transparent: Managed by MakerDAO’s smart contracts.
- Versatile: Used for payments, trading, and DeFi applications.
How Does DAI Maintain Its Peg?
- Collateralized Debt Positions (CDPs): Users lock crypto (e.g., ETH, BAT) to generate DAI.
- Dynamic Supply: If DAI > $1, the system encourages repayment to reduce supply. If DAI < $1, it incentivizes borrowing to increase supply.
- MKR Governance: MKR token holders vote on parameters (e.g., stability fees, collateral types).
💡 Did You Know? Multi-collateral DAI (launched 2019) supports multiple assets (e.g., ETH, BAT) as collateral, unlike its predecessor, Single-Collateral DAI (SAI).
How To Acquire DAI
- Borrow: Use MakerDAO’s Oasis to lock collateral and mint DAI.
- Exchange: Buy DAI on platforms like Coinbase or Uniswap.
- Earn: Deposit DAI in DeFi protocols (e.g., Compound, Aave) to earn interest.

DAI in DeFi
DAI is a cornerstone of DeFi, with services like:
- Coinbase Earn: 2% APY on DAI deposits.
- dPiggy: Auto-invests interest into other cryptos.
- WBTC Wrapping: Bitcoin holders can generate DAI via MakerDAO.
Regulatory Challenges
- STABLE Act (2020): Proposed U.S. regulation could classify DAI issuers as banks, threatening decentralization.
- Global Demand: In Argentina, DAI trading surged after USD purchase taxes were imposed.
The Future of DAI
MakerDAO aims to position DAI as the “unbiased global currency” by:
- Expanding collateral options (e.g., real-world assets).
- Enhancing brand recognition (e.g., universal currency symbol).
- Boosting adoption through education and partnerships.
