Decentralized Finance (DeFi) has transformed the way individuals interact with financial services, offering permissionless access to lending, borrowing, and earning opportunities. At the forefront of this movement is MakerDAO, one of the most influential protocols in the DeFi ecosystem. This comprehensive guide explores how MakerDAO works, how to mint its native stablecoin DAI, and the risks and benefits involved.
What Is MakerDAO?
MakerDAO is a decentralized autonomous organization (DAO) built on the Ethereum blockchain. It operates as a cornerstone of the DeFi landscape, enabling users to generate loans in the form of DAI, a dollar-pegged stablecoin, by locking up digital assets as collateral.
The protocol runs on smart contracts and is governed by holders of its native token, MKR. Unlike traditional financial institutions, MakerDAO doesn’t rely on intermediaries. Instead, it uses automated systems to manage loans, maintain stability, and enforce repayment—making it a truly decentralized lending platform.
Understanding Collateralized Debt Positions (CDPs)
At the heart of MakerDAO’s functionality are Collateralized Debt Positions (CDPs)—smart contracts that allow users to borrow DAI by depositing crypto assets as collateral.
Here’s how it works:
- A user deposits supported cryptocurrencies (like ETH or WBTC) into a CDP.
- The protocol mints an equivalent amount of DAI based on the collateral value.
- The user receives DAI, which can be used for trading, investing, or saving.
- To reclaim their collateral, the user must repay the DAI loan plus a stability fee.
If the value of the collateral drops too low—falling below a 150% collateralization ratio—the position is automatically liquidated. The system sells part of the collateral to cover the debt, protecting the protocol from under-collateralization.

How Does MakerDAO Maintain DAI’s Stability?
DAI is designed to maintain a soft peg to the US dollar, but unlike centralized stablecoins such as USDT, it isn’t backed by cash reserves. Instead, DAI’s stability is enforced through several mechanisms:
1. Over-Collateralization
Every loan must be backed by more value in crypto than the DAI borrowed—typically at least 150%. This buffer protects against market volatility.
2. Stability Fees
Users pay a fee in MKR tokens to open and maintain a CDP. These fees are adjusted by MKR holders through governance votes and help regulate DAI supply.
3. Automatic Liquidation
When collateral values drop, positions are liquidated to prevent losses. This keeps the system solvent even during market crashes.
4. MKR Dilution (Emergency Measure)
In extreme cases—such as widespread liquidations—the protocol can mint new MKR tokens and sell them to cover shortfalls. While this dilutes existing MKR holders’ value, it ensures DAI remains backed.
What Is DAI?
DAI is an ERC-20 token and one of the first decentralized stablecoins. Its value is algorithmically maintained near $1 using smart contracts and economic incentives rather than bank-held dollars.
DAI can be:
- Minted via MakerDAO by locking collateral.
- Bought on cryptocurrency exchanges.
- Used across DeFi platforms for trading, lending, or earning interest.
Because DAI is decentralized and transparently backed, it offers greater trustlessness compared to centralized alternatives like USDT or USDC.
How Is DAI Different From USDT?
| Feature | DAI | USDT |
|---|---|---|
| Backing | Crypto collateral + smart contracts | Cash reserves, bonds, commercial paper |
| Governance | Decentralized (MKR holders) | Centralized (Tether Ltd.) |
| Transparency | On-chain data | Audited financial reports |
| Risk Profile | Smart contract & volatility risk | Counterparty & regulatory risk |
While both aim to track the USD, DAI’s decentralization makes it a preferred choice for users who prioritize censorship resistance and transparency.
Key Use Cases of MakerDAO
1. Leverage Your Crypto Holdings
Instead of selling your ETH or BTC, you can use them as collateral to mint DAI and buy more assets—effectively leveraging your portfolio without triggering taxable events.
For example:
- Deposit $1,500 worth of ETH.
- Borrow $1,000 in DAI.
- Use DAI to purchase more ETH.
- Repay loan later when prices rise.
2. Earn Interest With DAI Savings Rate (DSR)
MakerDAO offers the DAI Savings Rate (DSR), allowing users to earn passive income by locking DAI in a smart contract. The rate is adjustable via governance and provides a reliable yield in stablecoins.
Access DSR through platforms like Oasis Save, where you can deposit and withdraw funds at any time.
3. Yield Farming Across DeFi
Borrowed DAI can be supplied to other DeFi protocols—like Aave or Curve—to earn annual percentage yields (APY) through liquidity provision or staking.

4. Borderless Transactions
Thanks to its stability, DAI is ideal for cross-border remittances and everyday transactions. It avoids the high fees and delays of traditional banking while minimizing price swings common with volatile cryptos.
How to Mint DAI: Step-by-Step
Minting DAI requires interacting directly with the MakerDAO protocol. Here’s how:
Step 1: Set Up a Web3 Wallet
Use a non-custodial wallet like MetaMask to store your crypto and connect to DeFi apps. Ensure it’s funded with supported collateral (e.g., ETH, WBTC).
Step 2: Connect to Oasis.app
Oasis is the official front-end for MakerDAO. Visit oasis.app and connect your wallet.
Step 3: Open a Vault
Select a vault type matching your collateral (e.g., ETH-A). Enter how much you want to deposit.
Step 4: Generate DAI
After depositing collateral, specify how much DAI you’d like to mint. Confirm the transaction via your wallet.
Once complete, DAI will appear in your wallet and can be transferred or used immediately.
🔐 Remember: You must repay the full loan + stability fee to retrieve your collateral.
The Role of MKR Token
MKR is MakerDAO’s governance and utility token, serving three core functions:
- Governance: MKR holders vote on key decisions—like risk parameters, new collateral types, and fee adjustments.
- Stability Mechanism: In crises, new MKR can be minted to recapitalize the system.
- Fee Payment: Stability fees are paid in MKR and then burned, reducing supply over time.
This deflationary model incentivizes long-term holding and responsible governance participation.
Risks of Using MakerDAO
Despite its innovation, MakerDAO carries notable risks:
⚠️ Volatility & Liquidation Risk
Sudden price drops—especially during "black swan" events—can trigger mass liquidations. In March 2020 ("Black Thursday"), ETH’s crash led to under-collateralized positions and over $8 million in losses.
💡 Tip: Maintain a 200%+ collateral ratio to reduce liquidation risk.
⚠️ Smart Contract Vulnerabilities
As with all DeFi platforms, bugs or exploits in code could lead to fund loss. While MakerDAO has never been hacked, audits and ongoing security monitoring are essential.
⚠️ Systemic Risk During Crises
If liquidations outpace recovery mechanisms, MKR dilution may occur—hurting token holders but preserving DAI’s peg.
Frequently Asked Questions (FAQ)
Q: Can I mint DAI without collateral?
A: No. All DAI must be backed by over-collateralized digital assets. Flash loans are not supported on MakerDAO.
Q: Is DAI truly pegged to $1?
A: Yes, DAI maintains a soft peg close to $1 through economic incentives and automated controls, though minor fluctuations occur.
Q: What happens if my vault gets liquidated?
A: The system sells your collateral to repay the debt. You lose part of your deposit and may incur penalties.
Q: Can I earn interest on DAI?
A: Yes. Use the DAI Savings Rate (DSR) or supply DAI to lending protocols like Aave or Compound.
Q: Is MakerDAO safe for beginners?
A: It’s user-friendly but involves complex risks. Start small, over-collateralize, and understand liquidation mechanics first.
Q: Where can I use DAI after minting?
A: Spend it on crypto marketplaces, send globally, invest in DeFi yield farms, or save it with interest-bearing accounts.
Final Verdict: Should You Use MakerDAO?
MakerDAO remains a pioneer in decentralized lending, offering powerful tools for borrowing, saving, and leveraging crypto assets without intermediaries. Its robust design, transparency, and integration across DeFi make it a top choice for experienced users.
However, it’s not without risk. Market volatility, liquidation threats, and smart contract dependencies mean users must act cautiously.
