What Is MakerDAO and How Does DAI Work?

·

In the fast-evolving world of cryptocurrency, volatility remains one of the most significant barriers to mainstream adoption. While price swings can create lucrative opportunities, they also introduce risk that deters traditional investors and financial institutions from fully embracing digital assets. This challenge has driven innovation in decentralized finance (DeFi), particularly in the area of stablecoins—cryptocurrencies designed to maintain a stable value.

Enter MakerDAO and its flagship stablecoin, DAI. Together, they form one of the most influential systems in DeFi, enabling users to borrow against crypto collateral while maintaining price stability. But how does it all work? Let’s explore the mechanics, use cases, and governance behind this pioneering protocol.

Understanding MakerDAO

Launched in 2014 by Rune Christensen and built on the Ethereum blockchain, MakerDAO is one of the longest-standing projects in the DeFi ecosystem. As a decentralized autonomous organization (DAO), it operates without central control—decisions are made collectively by holders of its governance token, MKR.

At its core, MakerDAO enables users to generate DAI, a dollar-pegged stablecoin, by locking up cryptocurrency as collateral in smart contracts known as Vaults. These Vaults are the backbone of the system, ensuring that every DAI in circulation is backed by real value.

By 2017, the DAI stablecoin was officially launched via the Maker Protocol, an open-source platform running on Ethereum. Since then, MakerDAO has grown into a cornerstone of DeFi, with over $7 billion in total value locked (TVL) across its network—a testament to its reliability and widespread adoption.

What Is DAI?

DAI is a decentralized stablecoin soft-pegged 1:1 to the U.S. dollar. Unlike centralized stablecoins such as USDT or USDC, which rely on reserves held in traditional banks, DAI maintains its stability through over-collateralized crypto assets locked within the Maker Protocol.

DAI is an ERC-20 token, meaning it’s compatible with any Ethereum-based wallet or application. Its value isn’t backed by cash—but by digital assets like Ether (ETH), Wrapped Bitcoin (WBTC), or Chainlink (LINK), depending on what collateral types are approved by MKR voters.

When users deposit these assets into a Vault, they can draw out a loan in DAI—up to a certain limit based on the collateralization ratio. This process allows individuals to access liquidity without selling their crypto holdings.

Key Features of DAI:

How Do Maker Vaults and DAI Generation Work?

The heart of MakerDAO’s lending mechanism lies in smart contracts, specifically called Vaults (formerly known as Collateralized Debt Positions or CDPs).

Here’s how it works:

  1. A user deposits supported crypto assets (e.g., ETH) into a Vault.
  2. The smart contract calculates the maximum amount of DAI they can borrow, based on the current collateralization ratio—typically set at 150%.
  3. For example: To borrow $1,000 worth of DAI, a user must deposit at least $1,500 worth of ETH.
  4. Once confirmed, the DAI is minted and sent directly to the user’s wallet.

This over-collateralization ensures that even if the price of ETH drops suddenly, there’s still enough value to cover the loan.

What Happens If Collateral Value Drops?

If market conditions cause the value of the collateral to fall below the required threshold (e.g., due to a sharp decline in ETH price), the Vault becomes undercollateralized and is subject to liquidation.

In this case:

If losses exceed available collateral, the Maker Buffer—funded by liquidation penalties and surplus revenue—is used to cover the shortfall. In extreme cases, new MKR tokens may be minted and sold to raise additional capital.

Step-by-Step: Creating a Vault and Generating DAI

Generating DAI is straightforward for anyone with an Ethereum wallet like MetaMask:

  1. Visit Oasis.app, MakerDAO’s official user interface for managing Vaults.
  2. Connect your wallet.
  3. Choose a collateral type (e.g., ETH-A for Ether).
  4. Deposit your chosen asset into a newly created Vault.
  5. Specify how much DAI you’d like to generate (within borrowing limits).
  6. Confirm the transaction—DAI will appear in your wallet almost instantly.

To close the Vault:

This entire process is trustless, permissionless, and executed entirely through code.

The Role of MKR: Governance and Stability

MKR is MakerDAO’s governance token and plays two critical roles:

  1. Protocol Governance: MKR holders vote on key decisions such as:

    • Adding new collateral types
    • Adjusting risk parameters (like stability fees)
    • Emergency shutdown procedures
    • Upgrades to smart contracts
  2. System Risk Absorption: When losses occur due to undercollateralized Vaults, MKR tokens are minted and sold on the market to recapitalize the system. Conversely, when revenue exceeds costs, MKR is bought back and burned—reducing supply and potentially increasing value.

With a maximum supply capped at approximately 1.006 million tokens, MKR embodies true decentralization: power rests not with a company or CEO, but with a distributed community of stakeholders.

Common Use Cases for DAI

DAI isn’t just for borrowing—it’s a versatile tool in the DeFi toolkit:

Frequently Asked Questions (FAQ)

Q: Is DAI truly decentralized?

Yes. Unlike centralized stablecoins audited by third parties, DAI is fully backed by on-chain collateral and governed by MKR token holders—making it one of the most decentralized stablecoins available.

Q: Can I lose money using MakerDAO Vaults?

Yes—if your collateral value drops too quickly and your Vault gets liquidated before you can top it up. It’s essential to monitor your collateralization ratio closely.

Q: How is DAI different from USDC or USDT?

USDC and USDT are backed by fiat reserves held in banks and subject to regulatory oversight. DAI is backed entirely by crypto assets and governed by code and community votes.

Q: Where can I use DAI?

You can spend DAI on thousands of DeFi platforms—from lending markets to NFT marketplaces—and even through crypto debit cards.

Q: What happens during a market crash?

MakerDAO includes safeguards like automatic liquidations and emergency shutdown mechanisms. In extreme scenarios, MKR tokens absorb losses to protect DAI’s peg.

Q: Can I earn interest on DAI?

Absolutely. By using services like the DAI Savings Rate (DSR) or lending platforms such as Compound or Aave, you can earn passive income on idle DAI balances.

Final Thoughts

MakerDAO represents a groundbreaking shift in how financial systems can operate—without intermediaries, borders, or gatekeepers. Through innovative use of smart contracts, over-collateralization, and community governance, it has created a resilient ecosystem anchored by the DAI stablecoin.

As DeFi continues to grow and evolve, MakerDAO remains at the forefront—offering a practical solution to crypto volatility while empowering users with financial sovereignty.

Whether you're looking to unlock liquidity from your holdings, hedge against market swings, or participate in decentralized governance, MakerDAO and DAI provide powerful tools for navigating the future of money.
