Dai (DAI)

What is Dai?

DAI is a decentralized stablecoin originally developed by MakerDAO (now Sky) — one of the oldest and most successful DeFi protocols. Unlike USDC and USDT which hold fiat reserves at banks, DAI maintains its peg through cryptocurrency collateral locked in smart contracts. Users deposit collateral (primarily ETH, wBTC, USDC, and other approved assets) and mint DAI against it in a process called Collateralized Debt Position (CDP).

DAI is the original “crypto-native stablecoin” — demonstrating that fiat-denominated stability can be achieved without bank custody of dollar reserves. The protocol has evolved significantly since launch: Single-Collateral DAI (2017) → Multi-Collateral DAI (2019) → increased reliance on USDC as collateral (2022-2024) → the MakerDAO-to-Sky rebrand (2024) with a planned transition toward new stablecoin USDS (though DAI remains operational and redeemable).

DAI has functioned reliably through multiple crypto market cycles, including the 2022 crypto winter, the Luna/UST collapse, and the 2023 Silicon Valley Bank crisis. Its worst single-event depeg was to $0.88 during the SVB crisis in March 2023 — driven by the fact that ~40% of DAI’s collateral at the time was USDC, which itself depegged when SVB failed.

How DAI Works

Collateralized Debt Positions (CDPs, now called “Vaults”):

• Users deposit approved collateral (ETH, wBTC, USDC, stETH, various others) into a Maker Vault
• They can mint DAI against the collateral up to a specific loan-to-value ratio (typically 60-75% depending on collateral type)
• If collateral value falls and the LTV exceeds the liquidation threshold, the position gets liquidated automatically
• Users pay “Stability Fees” (interest) on outstanding DAI debt

Peg stability mechanisms:

• Arbitrage: When DAI trades above $1, borrowers mint more DAI and sell it; when below $1, CDP holders buy DAI to repay debt
• Dai Savings Rate (DSR): Users can lock DAI to earn a protocol-adjusted yield, pulling DAI out of circulation when the peg needs support
• Peg Stability Module (PSM): Direct 1:1 USDC ↔ DAI conversion, letting DAI trade closely to $1 with USDC as an anchor
• Emergency Shutdown: A last-resort mechanism allowing DAI holders to redeem proportional collateral if the system fails

Governance:

• Originally MKR token holders voted on all parameters
• Under the Sky rebrand, governance has been partially migrated to SKY token
• Stability fees, debt ceilings, collateral approvals, and emergency actions all flow through governance

Collateral Composition

DAI’s collateral has evolved significantly:

• 2017-2020: Primarily ETH (single-collateral DAI)
• 2019-2022: Multi-collateral with ETH, wBTC, and other crypto
• 2022-2024: Increasing USDC backing (reaching ~60% at some points) for peg stability
• 2024-2026: Diversified across ETH, stETH, wBTC, USDC, and real-world assets (tokenized Treasuries)

The inclusion of real-world assets (tokenized US Treasuries, tokenized bonds) became a major evolution — approximately 20-30% of DAI backing is now via real-world assets, providing yield to the protocol that supports the Dai Savings Rate.

DAI vs USDC vs USDT

DAI operates differently from centralized stablecoins:

For most DeFi-native use cases, DAI is the default. For regulated US venues, USDC dominates. For global and Asian markets, USDT dominates.

MakerDAO → Sky Transition

In 2024, MakerDAO rebranded to Sky as part of the broader “Endgame” protocol evolution plan:

• SKY token: Will eventually replace MKR (1 MKR = 24,000 SKY)
• USDS: New stablecoin designed to succeed DAI long-term; DAI continues to operate in parallel
• SubDAOs: Specialized sub-protocols for different collateral types and use cases
• AI-augmented governance: Various experiments in using AI to assist governance decisions

DAI remains fully operational and redeemable through the transition. Users have optionality to hold DAI, USDS, or convert between them.

Use Cases

DeFi collateral: DAI is accepted as collateral or borrowing asset across nearly every major DeFi protocol (Aave, Compound, Curve, Convex, many more).

Trading pairs: DAI/ETH, DAI/USDC, and other DAI pairs are common on DEXes. Less common on centralized exchanges than USDC or USDT.

Savings (DSR): Users lock DAI in the Dai Savings Rate module to earn yield (currently ~5-8% APY as of 2026).

Cross-border transfers: Same as other stablecoins — instant, low-fee dollar-denominated transfers globally.

Crypto-native alternative to fiat stablecoins: Users preferring to avoid centralized issuers (Circle, Tether) choose DAI for philosophical decentralization reasons.

Risks and Considerations

• Collateral concentration: Heavy USDC backing means DAI depegs if USDC depegs (as happened in March 2023)
• Smart contract risk: DAI’s stability depends on complex smart contract systems; bugs or governance errors could affect the peg
• Governance risk: SKY/MKR token holders control key parameters; governance capture or poor decisions could harm the system
• Real-world asset risk: Growing RWA backing introduces traditional financial counterparty risk
• Regulatory evolution: DeFi stablecoin regulation is less settled than centralized stablecoin regulation
