关于 Dai (DAI)
The Dai stablecoin is a decentralized, unbiased, collateral-backed cryptocurrency soft-pegged to the US Dollar. Dai is held in cryptocurrency wallets or within platforms, and is supported on Ethereum and other popular blockchains.
Users mint Dai by depositing accepted collateral assets into Maker Vaults within the Maker Protocol. When the loan is repaid to retrieve the collateral, the paid back Dai is burned.
发行方与证明
Dai (DAI) is issued by MakerDAO (Sky Protocol), operating under Decentralised protocol governed by MKR (now SKY) token holders. Originally launched in 2017.
储备构成
Backed by a mix of crypto collateral (ETH, wstETH, LSTs), real-world asset vaults (US Treasuries via Monetalis/Clydesdale), and USDC held in the PSM.
重要锚定事件
In March 2023 the Maker community executed an emergency reduction of the PSM USDC exposure cap after the USDC depeg event.

锚定稳定性历史
As a crypto-collateralised stablecoin, Dai (DAI) maintains its 1.00 USD target by holding excess on-chain collateral and routing redemptions through automated liquidation auctions. Spot price is currently $1.0000 (-0.001%); short-term excursions are normal in this range are typically arbitraged away within hours via the protocol's open mint/redeem mechanics.
crypto-collateralised 稳定币如何维护其锚定
Crypto-collateralised stablecoins like this one over-collateralise positions — borrowers must lock more than $1.00 of crypto for each $1.00 of stablecoin minted. If collateral value falls below the required ratio, the position is automatically liquidated in an open Dutch auction. Arbitrageurs can always mint and redeem against the protocol's contracts, which keeps the secondary-market price tightly bounded around $1.00. The main residual risks are sudden crypto-collateral crashes that outpace the liquidation engine, and oracle failure.
对持有者的实际影响
- Collateral volatility is the dominant risk: a fast drawdown in the collateral asset can outpace liquidation auctions and leave the protocol under-collateralised.
- Oracle risk: the protocol relies on price feeds (typically Chainlink or a multi-oracle setup). Oracle manipulation or delay during volatile markets has historically caused peg excursions.
- Governance risk: parameter changes (collateral types, liquidation ratios, debt ceilings) are decided by token-holder votes. Sudden governance attacks remain a tail risk.
- On-chain transparency is a major advantage — collateral is verifiable 24/7 without trusting an attestor.
- Mantapex tracks peg deviation in real time from DeFiLlama price feeds, but for high-value holdings cross-check directly on at least one independent venue (CoinGecko, the issuer's own dashboard, or an on-chain DEX).
Peg-stability commentary is based on the mechanism class (crypto-collateralised) and is provided for educational purposes only — it is not financial advice. Past peg stability is not a guarantee of future performance, and even the highest-quality stablecoins have historically traded outside their target band during banking, regulatory, or liquidity stress.

将 Dai 与其他 crypto-collateralised 稳定币比较
Below are the largest crypto-collateralised stablecoins tracked on Mantapex alongside Dai (DAI). Comparing supply and chain footprint within the same mechanism class is more meaningful than cross-class comparison, because the underlying peg-defence assumptions are different.
