什麼是 Synthetix sUSD (SUSD)？
Synthetix sUSD is a decentralized synthetic stablecoin that functions as a core component of the Synthetix protocol, a derivatives liquidity platform built on the Ethereum and Optimism blockchains. Unlike traditional stablecoins that are backed by physical bank deposits or other fiat reserves, sUSD is a synthetic asset, or synth, designed to track the value of the United States dollar through a system of on-chain collateral and decentralized price feeds. The creation of sUSD is driven by the staking of the Synthetix Network Token, known as SNX. To mint sUSD, users must lock their SNX tokens into a smart contract as collateral. This process requires a high collateralization ratio, meaning the value of the staked tokens must significantly exceed the value of the sUSD being issued. This overcollateralization acts as a safety buffer to ensure the stability of the system even during periods of high volatility. When users mint sUSD, they effectively take on a portion of the protocols collective debt, which they must later clear by burning sUSD to unlock their original staked assets. Technically, sUSD relies on decentralized oracles, specifically from the Chainlink network, to maintain its peg. These oracles provide real-time price data that the protocol uses to ensure sUSD accurately reflects the value of the dollar within the ecosystem. Within the Synthetix platform, sUSD serves as the primary medium of exchange. It allows users to trade directly for other synthetic assets, such as synthetic versions of popular cryptocurrencies, commodities like gold, or even fiat currencies, without needing a traditional counterparty. This is achieved through a peer-to-contract model where trades are executed against the protocol itself. Beyond the native Synthetix exchange, sUSD is widely integrated into the broader decentralized finance ecosystem. It is used for providing liquidity in various decentralized exchanges, as collateral in lending protocols, and as a base currency for perpetual futures and other advanced trading products. Its decentralized and permissionless nature makes it a popular choice for users seeking a stable digital asset that does not rely on centralized financial institutions. Governance for the project is managed through a decentralized autonomous organization where various councils oversee protocol upgrades, collateral requirements, and the expansion of the synthetic asset offerings. 瞭解更多

Synthetix sUSD (SUSD) 常見問題
sUSD is a decentralized synthetic stablecoin designed to maintain a 1:1 peg with the US Dollar. Unlike stablecoins backed by traditional fiat reserves, sUSD is crypto-collateralized. Historically, it was primarily backed by the Synthetix Network Token (SNX). However, with the ongoing transition to the V3 protocol, its backing is evolving into a multi-collateral model, incorporating assets like SNX, ETH, and other stablecoins to enhance stability and flexibility.
sUSD maintains its $1 peg through a combination of robust over-collateralization and active arbitrage mechanisms. Stakers within the protocol typically lock up significantly more value in collateral than the sUSD they mint, providing a strong buffer. When the sUSD price deviates below $1, arbitrageurs and stakers are incentivized to purchase it at a discount. They then use this cheaper sUSD to burn and repay their debt, reducing the circulating supply and helping to restore the peg. Conversely, if sUSD goes above $1, minting new sUSD becomes profitable, increasing supply.
This common scenario arises from the protocol's "Pooled Debt" model. When you mint sUSD, you incur a debt that represents a percentage of the total debt across the entire system. This total debt isn't static; it fluctuates based on the value of all synthetic assets (Synths) minted by all participants. For example, if other users mint synthetic Bitcoin or Ethereum, and those assets increase in value, the overall system debt grows. Consequently, your individual debt will increase proportionally, even if you haven't minted additional sUSD yourself, because your share of the total system debt has increased.
Recent de-pegging events for sUSD have primarily been attributed to a confluence of factors, often involving shifts in market dynamics and protocol incentives. Incidents have sometimes stemmed from significant liquidity providers reducing their commitments, which can decrease the available arbitrage opportunities to maintain the peg. Additionally, adjustments to the protocol's economic incentives, such as those related to specific Synthetix Improvement Proposals (like SIP-420 mentioned in some discussions), have at times inadvertently weakened the manual arbitrage pressure needed to consistently buy back sUSD when it trades below its target value, contributing to temporary deviations from the $1 peg.
As the Synthetix protocol transitions to its V3 architecture, existing sUSD is being migrated to a new, updated version, sometimes referred to as snxUSD. This represents a significant upgrade, introducing new features and enhanced collateral models. Users holding the older sUSD will need to understand the migration process, which typically involves moving their positions to the new V3 system. This often requires users to interact with the protocol's official migration tools or follow specific instructions to either swap their legacy sUSD or update their staking positions to the new V3 pools, ensuring compatibility and access to future rewards and functionalities within the upgraded ecosystem.
The Collateralization Ratio (C-Ratio) is a critical metric for stakers within the Synthetix protocol. It represents the ratio of the value of your staked collateral, primarily Synthetix Network Token (SNX), to the value of the sUSD debt you have minted. This ratio constantly changes due to two main factors: fluctuations in the market price of your SNX collateral and changes in your sUSD debt (which, as discussed, can increase even if you don't mint more sUSD due to the pooled debt model). Maintaining a C-Ratio above a predefined target (e.g., 400-500%) is essential, as falling below this threshold can prevent you from claiming staking rewards until you either burn sUSD to reduce debt or add more SNX collateral.
