What is Dai (DAI)?
Dai (DAI) is a decentralized stablecoin soft-pegged to the US dollar, created and governed by the MakerDAO protocol on Ethereum. Unlike centralized stablecoins such as USDT or USDC, DAI is backed by over-collateralized crypto assets locked in smart contracts called Vaults, making it one of the most important primitives in decentralized finance.
Key Facts
What is Dai?
Dai is a decentralized, crypto-collateralized stablecoin that targets a value of $1 USD. It is issued by the Maker Protocol, a set of smart contracts on the Ethereum blockchain. Anyone can generate DAI by depositing collateral into a Maker Vault, and DAI can be freely transferred, traded, or used in DeFi applications.
Unlike USDT and USDC, which are backed by fiat reserves held by centralized companies, DAI is backed by cryptocurrency and real-world assets locked in transparent, auditable smart contracts. This makes DAI censorship-resistant - there is no single entity that can freeze or confiscate DAI tokens.
The Maker Protocol is governed by holders of the MKR governance token, who vote on risk parameters such as collateral types, debt ceilings, stability fees, and the Dai Savings Rate (DSR). This decentralized governance model gives DAI its unique position as one of the few truly decentralized stablecoins in the cryptocurrency ecosystem.
Who Created Dai? A Brief History
Origins: MakerDAO and Rune Christensen
MakerDAO was founded in 2014 by Rune Christensen, a Danish entrepreneur. The project was one of the earliest DeFi protocols on Ethereum, with the vision of creating a decentralized, unbiased currency that anyone could use. The Maker Foundation was established to support early development, though the project was always intended to become fully decentralized.
Single-Collateral Dai (SCD)
The first version of Dai launched on December 18, 2017, as Single-Collateral Dai (SCD), also known as "Sai." In this version, only ETH could be used as collateral through Collateralized Debt Positions (CDPs). Despite the simplicity, SCD successfully maintained its peg through the volatile crypto markets of 2018-2019.
Key Milestones
- • 2014: MakerDAO founded by Rune Christensen.
- • 2017: Single-Collateral Dai (SCD) launches on Ethereum mainnet, accepting only ETH as collateral.
- • 2019: Multi-Collateral Dai (MCD) launches on November 18, supporting multiple collateral types including ETH, BAT, and USDC.
- • 2020: DAI becomes a cornerstone of "DeFi Summer," reaching over $1 billion in circulation. Maker adds real-world assets (RWAs) as collateral.
- • 2021: The Maker Foundation officially dissolves, transferring all operations to the MakerDAO community.
- • 2023: MakerDAO introduces the "Endgame" plan to restructure governance into SubDAOs.
- • 2024: MakerDAO rebrands to Sky, introducing USDS and SKY tokens. DAI continues to exist alongside the new tokens.
Governance: MKR Token Holders
The Maker Protocol is governed by MKR token holders who participate in on-chain voting. They decide on critical parameters including which collateral types to accept, debt ceilings, stability fees, and the Dai Savings Rate. MKR also serves as the protocol's backstop - if the system becomes undercollateralized, new MKR tokens are minted and auctioned to cover the deficit, diluting MKR holders.
How Dai Works
Dai is generated when users deposit collateral into Maker Vaults and borrow DAI against it. The system is designed to always maintain over-collateralization, meaning the value of locked collateral exceeds the value of DAI issued.
Maker Vaults (formerly CDPs)
To generate DAI, a user locks collateral (such as ETH, WBTC, or other approved assets) into a Maker Vault smart contract. They can then borrow DAI up to a certain ratio of their collateral value - for example, with a 150% collateralization ratio, depositing $150 worth of ETH allows borrowing up to 100 DAI. Users pay a stability fee (interest rate) on their borrowed DAI, set by MKR governance.
Liquidation Mechanics
If the value of a Vault's collateral falls below the required collateralization ratio (due to price drops), the Vault becomes eligible for liquidation. Keepers - automated bots that monitor the protocol - trigger liquidation auctions where the collateral is sold to cover the outstanding DAI debt plus a liquidation penalty.
This mechanism ensures DAI always remains backed, even during market crashes.
Dai Savings Rate (DSR)
The DSR allows any DAI holder to earn yield by depositing DAI into the DSR contract. The interest rate is set by MKR governance and is funded by stability fees collected from Vault users. The DSR serves as a monetary policy tool - raising the DSR encourages holding DAI (reducing supply), while lowering it encourages spending or selling DAI.
Peg Stability Mechanisms
DAI maintains its $1 peg through several mechanisms working together:
| Scenario | Mechanism | Effect |
|---|---|---|
| DAI > $1 | Lower stability fees / DSR | Encourages minting more DAI, increasing supply |
| DAI < $1 | Raise stability fees / DSR | Encourages repaying DAI, reducing supply |
| Collateral drops | Automatic liquidation | Sells collateral to maintain backing |
| System deficit | MKR dilution auction | New MKR minted and sold to cover shortfall |
Dai vs USDT & USDC
All three are USD-pegged stablecoins, but they differ fundamentally in how they maintain their peg and who controls them.
| Feature | DAI | USDT | USDC |
|---|---|---|---|
| Issuer | MakerDAO (decentralized) | Tether Limited | Circle |
| Backing | Crypto collateral + RWAs | Cash, treasuries, loans | Cash, short-term treasuries |
| Transparency | Fully on-chain, real-time | Quarterly attestations | Monthly attestations |
| Can be frozen? | No | Yes | Yes |
| Governance | MKR token holders | Tether Limited | Circle |
| Key risk | Smart contract / collateral risk | Reserve transparency | Regulatory / centralization |
DAI's decentralized design makes it the preferred stablecoin for users who value censorship resistance and on-chain transparency. However, it carries smart contract risk and has experienced brief depegging events during extreme market volatility. USDT and USDC offer simpler backing models but require trusting their centralized issuers.
Why Dai Has Value
DAI derives its value from its reliable $1 peg, maintained through transparent, over-collateralized smart contracts. Unlike centralized stablecoins, no single entity controls DAI - it operates as a public good on Ethereum.
DAI is one of the most integrated tokens in DeFi. It is accepted as collateral on lending platforms like Aave and Compound, used in liquidity pools across decentralized exchanges, and serves as a stable unit of account in countless DeFi protocols. This deep integration creates strong network effects and sustained demand.
The Dai Savings Rate (DSR) provides a native yield mechanism, allowing holders to earn interest without counterparty risk from centralized lenders. Combined with its censorship resistance and transparent collateral, DAI offers a unique value proposition that centralized stablecoins cannot replicate.
How to Buy Dai
DAI can be purchased on most major cryptocurrency exchanges, or you can generate it yourself by opening a Maker Vault with crypto collateral.
1Compare providers
DAI is available on major exchanges including Coinbase, Kraken, Binance, and many others. Since DAI is pegged to $1, fees and spreads matter more than price differences. Compare total costs across platforms.
2Create an account
Register on your chosen exchange and complete identity verification (KYC). Enable two-factor authentication for security.
3Fund your account
Fund your account via bank transfer, credit/debit card, or by depositing other cryptocurrencies. You can also swap other stablecoins (USDT, USDC) for DAI on decentralized exchanges like Uniswap with minimal slippage.
4Buy DAI
Place an order for DAI. Since it is a stablecoin, market orders are generally safe. Alternatively, generate DAI directly by depositing collateral into a Maker Vault at oasis.app (for advanced users).
5Withdraw and earn with DSR
Withdraw DAI to your personal wallet. Consider depositing into the Dai Savings Rate (DSR) contract to earn yield on your holdings.

How to Store Dai
Wallet types
DAI is an ERC-20 token, so it can be stored in any Ethereum-compatible wallet:
- • Software wallets: MetaMask, Coinbase Wallet, Rainbow, Trust Wallet
- • Hardware wallets: Ledger, Trezor (highest security for large amounts)
- • DeFi-native wallets: Rabby, Frame (optimized for DeFi interactions)
Hardware Wallets
Ledger and Trezor both support DAI as an ERC-20 token. Hardware wallets provide the best security for storing significant amounts of DAI, keeping your private keys offline while still allowing you to interact with DeFi protocols.
Dai Savings Rate (DSR)
Instead of simply holding DAI, consider depositing it into the DSR contract to earn yield. The DSR is a native, permissionless savings mechanism - your DAI remains under your control and can be withdrawn at any time. The rate is set by MKR governance and varies over time.
Seed phrase and security
When setting up a self-custody wallet, you'll receive a seed phrase (12 or 24 words). Write it down on paper and store it securely offline. Never share your seed phrase or enter it on websites. Anyone with your seed phrase can access your funds.
How to Use Dai (DAI)
DeFi Lending and Borrowing
DAI is one of the most widely supported stablecoins in DeFi. Deposit DAI on lending platforms like Aave or Compound to earn interest, or use it as collateral to borrow other assets. DAI's decentralized nature makes it preferred collateral in many DeFi protocols.
Payments and Transfers
Send DAI to anyone with an Ethereum address, 24/7, without intermediaries. DAI transactions settle in minutes on Ethereum mainnet, or in seconds on Layer 2 networks like Arbitrum and Optimism at much lower gas fees.
Savings and Yield
The Dai Savings Rate (DSR) provides a native savings mechanism. Additionally, DAI can be deposited in liquidity pools on decentralized exchanges (Uniswap, Curve) to earn trading fees, though this carries impermanent loss risk.
Trading Pair
DAI serves as a stable trading pair on decentralized exchanges. Traders use DAI to park profits during volatile markets without relying on centralized stablecoins that could be frozen.
Risks
While DAI targets $1, it carries unique risks: smart contract bugs could affect the Maker Protocol, extreme market crashes could lead to under-collateralization, and governance decisions by MKR holders could impact DAI's stability. DAI has also included centralized stablecoins (like USDC) as collateral, which introduces indirect centralization risk.
During the March 2023 USDC depeg event, DAI briefly depegged as well due to its USDC exposure.

Regulation Overview for Dai
Stablecoin Regulation
Stablecoins are an area of active regulatory focus worldwide. As a decentralized stablecoin without a single issuer, DAI presents unique regulatory challenges. It does not fit neatly into existing frameworks designed for centralized stablecoins backed by bank deposits. Regulators in various jurisdictions are still determining how decentralized stablecoins should be classified and regulated.
Country Differences
DAI's regulatory treatment varies by jurisdiction:
United States: DAI is legal and widely available on regulated exchanges. Stablecoin-specific legislation is under development. Tax treatment follows standard crypto rules - capital gains apply, though gains on a $1-pegged asset are typically minimal.
Canada: Legal and available on Canadian exchanges. Subject to existing crypto regulations under FINTRAC.
European Union: The MiCA regulation framework includes specific provisions for stablecoins. As a decentralized stablecoin, DAI's status under MiCA is still being clarified.
Australia: Legal and available on Australian exchanges. Subject to standard cryptocurrency regulations under AUSTRAC.
Regulations continue to evolve rapidly in the stablecoin space. Always verify current rules in your jurisdiction.
Decentralized Compliance
Unlike USDT and USDC, DAI cannot comply with freeze or blacklist requests because it has no central issuer. While this makes DAI censorship-resistant, it also means regulators cannot directly enforce asset freezes. Users are responsible for their own tax reporting and compliance when using DAI.
