★ Oracle source = spot DEX pool (no TWAP)
Falcon Finance's assessment for RD-F-053 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
[★ CRITICAL — GREEN] All 19 confirmed oracle feeds are Chainlink push-oracles. No DEX spot price or TWAP pattern identified. Zero slot0() or getReserves() calls in any verified Falcon contract. Both custom feeds are standard EACAggregatorProxy contracts.
Detail #
Data cache oracle_feeds: 19 entries, all provider='Chainlink', all with documented heartbeat_seconds and deviation_threshold_pct. USDf impl (0x3aDf...) and sUSDf impl (0x0D132bEE...) confirmed no DEX oracle calls via Etherscan readContract inspection. Custom feeds 0xb177857a... and 0xe471bc94... are EACAggregatorProxy (Solidity 0.6.6, MIT, 1M optimizer runs) — standard Chainlink aggregator pattern, not DEX pool reads.

Methodology #
Determine whether the primary oracle for any asset/market reads spot price from a single DEX pool without a TWAP window or secondary source.
