Max-deviation threshold (bps)
crvUSD (Curve Stablecoin)'s assessment for RD-F-058 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Chainlink safety limit = ±1.5% = 150 bps for collateral price oracles when use_chainlink=true. Chainlink ETH/USD and BTC/USD feeds have 0.5% deviation threshold (50 bps) on the feed side. 150 bps deviation cap is a meaningful control when active. AggregatorStablePrice has no explicit numeric deviation threshold beyond MIN_LIQUIDITY pool exclusion.
