★ Oracle source = spot DEX pool (no TWAP)
JustLend DAO'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 #
JustLend does NOT use a spot DEX pool as the oracle source. The oracle is a pushed-price model: a designated poster role reads Chainlink Data Feeds (aggregated multi-source, not a single DEX pool) and submits prices on-chain via setPrice(). Chainlink Data Feeds use AggregatorV3Interface on TRON mainnet (e.g. BTC/USD, ETH/USD) — these are not DEX spot prices. F053 critical check: green.
