DAI is a decentralized stablecoin engineered to maintain a stable value of $1 USD. Unlike traditional fiat-backed stablecoins such as Tether (USDT) or USD Coin (USDC), DAI operates on a unique collateralized model powered by smart contracts and governed through a decentralized autonomous organization (DAO). Built on the Ethereum blockchain, DAI was introduced by MakerDAO—a pioneering force in decentralized finance (DeFi)—to offer a transparent, trustless, and globally accessible digital dollar.
The concept was first proposed in 2014 by Rune Christensen, the co-founder and CEO of MakerDAO, with the vision of creating a stablecoin that didn’t rely on centralized reserves. After years of development, the first version—Single-Collateral Dai—launched in December 2017, initially backed solely by Ethereum (ETH). Over time, the system evolved into Multi-Collateral Dai, allowing multiple crypto assets as collateral, significantly expanding its utility and resilience across the DeFi ecosystem.
Today, DAI stands as one of the most widely adopted decentralized stablecoins, trusted for its transparency, over-collateralization model, and resistance to censorship.
How Does DAI Work?
At the core of DAI’s stability lies a sophisticated yet elegant system built on four key components: Collateralized Debt Positions (CDPs), stability mechanisms, decentralized governance, and the Ethereum blockchain.
1. Collateralized Debt Positions (CDPs)
Users generate DAI by locking up digital assets—primarily ETH and other ERC-20 tokens—into smart contracts known as Collateralized Debt Positions (CDPs), now referred to as Vaults. When you deposit collateral into a Vault, you can borrow DAI up to a certain limit, typically requiring at least 150% over-collateralization. For example, to mint $150 worth of DAI, you must deposit $225 worth of ETH.
This over-collateralization acts as a buffer against market volatility. If the value of the collateral drops too close to the debt level, the system automatically liquidates part of the collateral to protect the integrity of DAI’s peg.

2. Stability Mechanisms
Maintaining a consistent $1 peg is critical. To achieve this, MakerDAO employs dynamic stability fees and incentive mechanisms:
- When DAI trades above $1, the system encourages users to open more Vaults and generate additional DAI by lowering borrowing costs (stability fees).
- When DAI trades below $1, incentives shift: users are rewarded for buying and retiring DAI from circulation, effectively reducing supply and pushing the price back toward parity.
These market-driven feedback loops help stabilize DAI without relying on centralized intervention.
3. Decentralized Governance (MKR Token)
While DAI is the stablecoin, MKR is the governance token that powers decision-making within MakerDAO. Holders of MKR vote on crucial proposals such as:
- Adding new types of collateral
- Adjusting risk parameters
- Upgrading smart contracts
- Managing emergency shutdown procedures
This governance model ensures that no single entity controls the protocol, reinforcing DAI’s decentralization and community-led evolution.
4. Built on Ethereum
As an ERC-20 token, DAI inherits Ethereum’s security and composability. It seamlessly integrates with thousands of DeFi protocols—from lending platforms like Aave to decentralized exchanges like Uniswap—making it a foundational layer in the Web3 financial stack.
What Is DAI Used For?
DAI’s stability and decentralization make it ideal for a wide range of applications across the crypto economy.
Medium of Exchange & Store of Value
In regions with unstable local currencies or restricted financial access, DAI serves as a reliable digital dollar. Merchants and individuals use it for cross-border payments, remittances, and peer-to-peer transactions without intermediaries.
Its price stability also makes it a preferred store of value during periods of high crypto market volatility, offering a safer alternative to holding BTC or ETH directly.
Powering Decentralized Finance (DeFi)
DAI is one of the most integrated stablecoins in DeFi. Key use cases include:
- Lending & Borrowing: Platforms like Compound and Aave use DAI as both collateral and loanable asset.
- Yield Farming: Users provide DAI liquidity to earn rewards on decentralized exchanges.
- Stable Pairs in Trading: Traders use DAI/ETH or DAI/BTC pairs to hedge exposure while staying within crypto ecosystems.
- Smart Contract Payments: Developers use DAI for predictable payouts in dApps and DAO treasuries.

The Founders Behind MakerDAO
Rune Christensen – Co-Founder & Former CEO
Rune Christensen founded MakerDAO with a vision to create a decentralized alternative to traditional finance. With a background in web design and entrepreneurship, he transitioned into blockchain innovation and led MakerDAO through its formative years. Though he stepped down as CEO in 2023, his influence remains central to DAI’s philosophy and long-term roadmap.
Andy Milenius – Former CTO & Co-Founder
Andy Milenius brought technical expertise from his experience at Google and early-stage startups. He played a pivotal role in designing the initial architecture of MakerDAO’s smart contracts. He left the project in 2019 but contributed foundational code that continues to underpin the system.
The MakerDAO team has since grown into a global collective of developers, economists, and community contributors committed to advancing financial sovereignty.
Why Choose DAI Over Other Stablecoins?
| Feature | DAI | USDT / USDC |
|---|---|---|
| Backing | Crypto collateral (ETH, etc.) | Fiat reserves (USD bank deposits) |
| Transparency | On-chain, auditable | Requires third-party audits |
| Centralization | Fully decentralized | Centralized issuance |
| Accessibility | Permissionless | Subject to compliance checks |
This contrast highlights DAI’s unique value proposition: decentralization without reliance on traditional banking infrastructure.
Frequently Asked Questions (FAQ)
Q: Is DAI really worth $1?
A: Yes, DAI is algorithmically designed to maintain a soft peg to $1 USD. While short-term fluctuations occur due to market conditions, incentive mechanisms quickly restore equilibrium.
Q: Can I redeem DAI for cash?
A: Not directly through MakerDAO. However, you can trade DAI for fiat currencies like USD on major cryptocurrency exchanges such as OKX, Coinbase, or Binance.
Q: Is DAI safe?
A: DAI is considered secure due to its over-collateralization model and rigorous risk management. However, risks include smart contract vulnerabilities and extreme market crashes that could challenge liquidation systems.
Q: How is DAI different from USDC?
A: USDC is backed by real-world dollars held in banks and issued by regulated entities. DAI is backed entirely by crypto assets locked in smart contracts and governed by code and community votes.
Q: Where can I get DAI?
A: You can generate DAI by depositing collateral into Maker Vaults or purchase it directly on crypto exchanges. Many wallets support instant swaps into DAI.
Q: Does holding DAI earn interest?
A: Not automatically—but when used in DeFi protocols like lending platforms or liquidity pools, your DAI can generate yield ranging from 2% to 8% annually depending on market conditions.
