Chainlink aggregator min/max bound misconfig

Falcon Finance's assessment for RD-F-060 — scored gray on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

minAnswer/maxAnswer for custom USDf/USD and sUSDf/USDf feeds not retrieved. Standard ETH/USD and BTC/USD feeds have known Chainlink defaults. Custom feed bounds are the unknown risk.

Detail #

EACAggregatorProxy contracts expose minAnswer/maxAnswer via the underlying AccessControlledOffchainAggregator. Not queried within time budget. Standard Chainlink mainnet feeds (ETH/USD 0x5f4eC3..., BTC/USD 0xF4030...) have well-documented parameters; the custom Falcon feeds are the audit concern.
