Oracle staleness check present

Marinade Finance's assessment for RD-F-059 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Not applicable — the factor measures staleness checks on external oracle push feeds with timestamps. Marinade's mSOL exchange rate is derived from live Solana stake account lamport state via the update_price crank each epoch. There is no external push feed with a timestamp to check for staleness. The on-chain rate reflects consensus-level state.

Methodology #

Determine whether the protocol rejects oracle reads older than a declared maximum age (i.e., checks `updatedAt > block.timestamp - maxStaleness`).
