Peg stability history
As a crypto-collateralised stablecoin, Quill USD (USDQ) 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 (+0.000%); short-term excursions are normal in this range are typically arbitraged away within hours via the protocol's open mint/redeem mechanics.
How crypto-collateralised stablecoins defend their peg
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.
Practical implications for holders
- 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.
Contract addresses
Quill USD (USDQ) is deployed as a token contract on 1 blockchain network below. Always verify the contract address you're interacting with on the relevant block explorer before sending funds — phishing tokens reusing well-known stablecoin tickers are common, especially on newer chains.
