关于 sUSD (SUSD)
Synthetix is a protocol for issuing and trading synthetic assets on Ethereum. Each synthetic asset (or Synth) is an ERC20 token which tracks the price of an external asset; for example each sUSD token tracks the price of the US dollar.
An SNX holder can mint sUSD by locking their SNX as collateral via the Synthetix smart contract. sUSD can be burned to swap to another synthetic asset or to repay the debt to retrieve the collateral.
发行方与证明
sUSD (SUSD) is issued by Synthetix Protocol, operating under Decentralised, governed by SNX holders. Originally launched in 2018.
储备构成
Minted by staking SNX as collateral at a high collateralisation ratio (currently 750%+ historically). Backed by the broader Synthetix debt pool rather than direct US dollar reserves.

近期供应活动
sUSD (SUSD) supply contracted by US$2.4万 (-0.06%) in the last 24 hours, contracted by US$1.6万 (-0.04%) over the past week, and expanded by US$6.5万 (+0.15%) over the past 30 days.
Steady issuance: supply has held roughly flat (0.15% over 30 days), consistent with mature stablecoin liquidity dynamics.

锚定稳定性历史
As a crypto-collateralised stablecoin, sUSD (SUSD) maintains its 1.00 USD target by holding excess on-chain collateral and routing redemptions through automated liquidation auctions. Spot price is currently $0.8259 (-17.414%); short-term excursions of this magnitude 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.
