Risks identified
- Oracle
Synths and perps price entirely off external oracles. A false price feed has already been exploited: in June 2019 a bad sKRW rate (~1000x) let a bot arbitrage into sETH with over $1B of notional exposure before the oracle was halted. Perps V2/V3 rely on Pyth off-chain feeds delivered by keepers, so feed manipulation, staleness, or keeper failure remains a live risk.
- Reserve / Depeg
sUSD is not reserve-backed; it is minted against pooled SNX/protocol collateral and holds its peg through staker incentives. After SIP-420 lowered the collateral ratio and pooled the debt, the buy-back-below-peg incentive weakened and sUSD depegged ~31% to ~$0.68 in April 2025, requiring a debt jubilee and forced 420-Pool sUSD ratios to recover.
- Systemic
All SNX stakers share a single pooled debt: a staker's liability rises when other participants' synth positions gain value. This mutualized 'debt pool' design means concentrated winning trades, oracle errors, or a synth mispricing can inflate the debt every staker owes, a structural risk distinct from isolated-margin perp venues.
- Smart Contract
The V3 rebuild is large and novel; the iosiro V3 audit found 6 high and 11 medium-risk issues (all addressed) and attributed them partly to the size and complexity of a first-time-audited new system. The multi-contract modular architecture and ongoing SIP-driven upgrades keep contract-risk surface high.
- Governance
Protocol parameters (collateral ratios, fees, market listings, debt policy) are set by elected councils via SIPs/SCCPs. Governance moved fast and materially — e.g. SIP-420's collateral change directly triggered the 2025 sUSD depeg — so governance decisions can rapidly alter risk for stakers and synth holders.
