Introduction to Stablecoins and DAI
Unless you're new to cryptocurrency, you've likely encountered stablecoins—digital assets pegged to real-world values like fiat currencies or commodities. Unlike volatile cryptocurrencies such as Bitcoin or Ethereum, stablecoins offer stability, making them ideal for everyday transactions and hedging against market fluctuations.
Among the top stablecoins, DAI stands out as the first decentralized, crypto-collateralized stablecoin. Created by the Maker Protocol, DAI maintains its USD peg through innovative blockchain mechanisms rather than centralized reserves. With a market cap exceeding $5.3 billion, DAI powers hundreds of decentralized applications (dApps) and services across the crypto ecosystem.
What Is DAI?
DAI is a multi-collateral-backed stablecoin managed by MakerDAO, operating as an ERC-20 token on Ethereum. Unlike centralized stablecoins (e.g., USDT, USDC), DAI leverages smart contracts to function in a trustless, decentralized manner. Its hybrid model combines crypto collateral with algorithmic stability mechanisms to maintain its 1:1 USD peg.
Key Features:
- Decentralized Governance: Controlled by MakerDAO, a Decentralized Autonomous Organization (DAO).
- Multi-Collateral Backing: Supported by cryptocurrencies (ETH, WBTC) and stablecoins (USDC, USDP).
- Overcollateralization: Ensures stability even if collateral values fluctuate.

History of DAI
Launched in December 2017 by the Maker Foundation, DAI was designed to serve as a stable medium of exchange within the Maker Protocol's lending ecosystem. Its name derives from a Chinese term meaning "to lend." Control was later transferred to MakerDAO, making DAI one of the most decentralized stablecoins today.
Use Cases for DAI
1. Hedge Against Volatility
DAI provides a stable store of value amid crypto market swings, ideal for traders and long-term holders.
2. Fiat Alternative
With inflation eroding traditional savings, DAI offers a blockchain-based alternative to bank deposits—permissionless and self-custodial.
3. Everyday Payments
Use DAI for:
- DeFi platforms: Lending, borrowing, and yield farming.
- Physical/digital purchases: Pay for coffee or in-game items with low-fee EVM chains.
4. Profit-Taking
Artists, traders, and service providers use DAI to lock in profits without off-ramping to fiat.
How DAI Maintains Its Peg
1. Vaults and Keepers
- Users deposit collateral (e.g., ETH) into vaults to mint DAI.
- Keeper accounts liquidate undercollateralized vaults to stabilize supply.
2. Stability Fee
A variable interest rate (like a loan APR) charged when repaying DAI to reclaim collateral.
3. DAI Savings Rate (DSR)
Earn interest by locking DAI in smart contracts—funded by stability fees.

Risks and Challenges
1. Crypto Volatility
DAI’s collateral (e.g., ETH, WBTC) is subject to market crashes, though overcollateralization cushions impacts.
2. Centralized Backing
USDC (managed by Circle) comprises a significant portion of DAI’s reserves, introducing counterparty risk.
3. Historical Depegs
In March 2023, DAI fell to $0.87 during the Silicon Valley Bank crisis due to USDC exposure.
FAQs About DAI
Q: Is DAI backed by USD?
A: No—DAI is backed by crypto and stablecoins (e.g., USDC, ETH), not fiat.
Q: How is DAI different from USDT?
A: DAI is decentralized and algorithmically stabilized, while USDT is centrally issued and fiat-backed.
Q: Can I earn interest on DAI?
A: Yes! Use the DAI Savings Rate (DSR) or DeFi platforms like Compound.
Q: What happens if collateral value drops?
A: Vaults are liquidated to maintain DAI’s peg; overcollateralization provides a buffer.
Final Thoughts
DAI remains a pioneer in decentralized stablecoins, balancing innovation with resilience. Its DAO governance, multi-collateral design, and Ethereum compatibility make it a cornerstone of DeFi. For users prioritizing self-custody and censorship resistance, DAI offers a compelling alternative to centralized stablecoins.
