MakerDAO (MKR) is a groundbreaking decentralized financial system that issues Dai, a crypto-backed stablecoin designed to maintain a 1:1 peg with the U.S. dollar. Unlike traditional fiat-backed stablecoins, Dai operates entirely on the Ethereum blockchain through smart contracts, offering a truly decentralized alternative for digital finance.
Today, Dai is widely used across major DeFi platforms such as Aave, Compound, and Uniswap. To fully understand how Dai works and why MakerDAO stands out in the world of decentralized finance, let’s explore the key differences between centralized and decentralized stablecoins.
Centralized vs. Decentralized Stablecoins
Stablecoins are often described as “digital dollars” because they maintain a relatively stable value—typically pegged to the U.S. dollar—making them ideal for preserving capital in the volatile crypto market.
Crypto investors rely on stablecoins for several reasons:
- They provide a safe haven to park funds without exiting the crypto ecosystem.
- Transferring stablecoins between exchanges is fast, cheap, and efficient.
- Many DeFi protocols offer high-yield returns on stablecoin deposits.
- Users can borrow other assets using stablecoins as collateral.
While these benefits are clear, not all stablecoins are created equal. Most popular stablecoins like USDT, USDC, GUSD, and PAX are centralized—they are backed by real U.S. dollars held in reserve by regulated financial institutions. This means there’s an actual bank vault somewhere storing physical cash to back each token issued.
Think of these as the "AOL of digital money"—they simply digitize traditional fiat currency. But just like traditional dollars, they depend on centralized entities that control issuance and custody. Companies behind USDT and USDC act like digital central banks, requiring extensive third-party audits and regulatory oversight.
For users who value decentralization, privacy, and censorship resistance, these centralized models fall short. What’s needed instead is a fully decentralized stablecoin system—and that’s exactly what MakerDAO delivers.
What Is MakerDAO?
MakerDAO is a decentralized autonomous organization (DAO) that functions as a decentralized bank on the Ethereum blockchain. It issues Dai, a stablecoin that is soft-pegged to the U.S. dollar through algorithmic mechanisms rather than direct fiat reserves.
Here’s a crucial distinction:
While centralized stablecoins are backed by dollars, Dai is pegged to the dollar via price oracles and economic incentives built into the protocol.
The core mechanism works like this:
- Users deposit accepted cryptocurrencies (like ETH or WBTC) into a Maker Vault.
- This opens a collateralized debt position (CDP).
- Users can then withdraw Dai up to a certain percentage of their deposited collateral.
- To reclaim their collateral, users must repay the borrowed Dai plus a stability fee.
This system relies on over-collateralization to mitigate risk. For example, if you want to borrow $500 worth of Dai, you might need to deposit $750 worth of ETH (a 150% collateral ratio). This buffer protects the system during market volatility and prevents insolvency when asset prices drop sharply.

How Maker Vaults Work
The heart of MakerDAO lies in its Vault system—a smart contract-based mechanism where users lock up crypto assets to generate new Dai.
When you deposit collateral into a Vault, you gain the ability to mint new Dai tokens. These tokens are created (or “minted”) only when collateral is secured and are destroyed when debt is repaid—making Dai’s supply elastic.
This elastic supply model allows the protocol to automatically adjust the amount of Dai in circulation based on market conditions:
- When Dai trades below $1, arbitrageurs repay loans to burn excess supply, pushing the price back up.
- When Dai trades above $1, users open new Vaults to mint more Dai, increasing supply and lowering the price.
Because all activity occurs on-chain, every transaction is transparent, immutable, and auditable by anyone. This ensures trustlessness and eliminates reliance on intermediaries.
To prevent liquidations during price swings, Maker enforces strict minimum collateral ratios—often starting at 150%. For instance, with ETH priced at $2,000, borrowing 3,000 Dai would require depositing at least 2.25 ETH (~$4,500).
Once generated, Dai can be used like any digital cash: traded, sent, saved, or invested across thousands of DeFi applications.
How Does Dai Maintain Its $1 Peg?
Despite having no physical dollar reserves, Dai has consistently maintained its dollar peg since launch. This stability comes from a combination of economic design and market incentives:
- Over-collateralized backing: Total value locked in Vaults exceeds total Dai supply.
- Market-driven rebalancing: Traders profit from arbitrage opportunities when Dai deviates from $1.
- Dynamic risk parameters: MKR token holders vote on adjustments to stability fees, collateral types, and liquidation thresholds.
These mechanisms work together to ensure long-term price stability—even during extreme market conditions.
Using MakerDAO: Getting Started with Oasis
To interact directly with MakerDAO, users typically use Oasis.app, an intuitive front-end interface for creating Vaults and generating Dai.
To get started:
- Connect a Web3 wallet like MetaMask.
- Choose from a list of supported collateral assets (e.g., ETH, WBTC, LINK).
- Open a Vault and set your desired loan amount.
- Withdraw your newly minted Dai.
However, you don’t need to open a Vault to acquire Dai. You can easily buy it on major exchanges like Coinbase, Binance, or decentralized platforms like Uniswap.

The Role of MKR: Governance and Emergency Controls
MKR is the governance token of the MakerDAO ecosystem. Holders of MKR tokens have voting rights on critical decisions such as:
- Adding new types of collateral
- Adjusting stability fees
- Modifying risk parameters
- Initiating emergency shutdowns (in case of systemic threats)
As a DAO, MakerDAO operates without central control. Instead, decisions are made collectively by MKR stakeholders through transparent on-chain voting.
This decentralized governance model ensures resilience and alignment with community interests—key principles in the evolution of Web3 finance.
Frequently Asked Questions (FAQ)
Q: Is Dai truly decentralized?
A: Yes. Unlike USDT or USDC, Dai is not controlled by any single company or government. It runs autonomously on Ethereum via smart contracts and is governed by MKR token holders.
Q: Can I lose money using Maker Vaults?
A: Yes—if the value of your collateral drops below the required threshold, your Vault may be liquidated. Always monitor your collateralization ratio closely.
Q: How is Dai different from other algorithmic stablecoins?
A: Most algorithmic stablecoins rely solely on code-based supply adjustments. Dai combines over-collateralization with algorithmic controls, making it more resilient.
Q: What happens if the system fails?
A: In emergencies, MKR holders can trigger a global settlement—a fail-safe that freezes the system and allows users to claim their fair share of remaining assets.
Q: Do I earn interest when I hold Dai?
A: Not directly—but you can deposit Dai into yield-generating protocols like Aave or Curve Finance to earn passive income.
Q: Why does over-collateralization matter?
A: It protects the system against volatility. Since crypto prices can swing rapidly, extra collateral ensures loans remain secure even during sharp downturns.
