External keeper/relayer not redundant
JustLend DAO's assessment for RD-F-062 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
The oracle price-update system relies on a single designated poster address. The docs describe poster() as returning 'Address of the current poster.' There is no documented redundancy (multiple posters, backup poster, or automatic Chainlink pull). If the poster key is lost, compromised, or the operator goes offline, price updates stop. No failover mechanism is documented. This is a single point of failure in the keeper/relayer layer.
