Fallback behavior on oracle failure
JustLend DAO's assessment for RD-F-051 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
No fallback oracle is documented. If the poster stops submitting prices, the last stored price persists indefinitely in the prices mapping with no timeout or revert. SimplePriceOracle.sol stores prices as a simple mapping(address => uint) with no timestamp. PriceOracleProxy.sol has no secondary source. No documentation of halt-on-stale or last-known-price-with-timeout behavior.
