★ Oracle source = spot DEX pool (no TWAP)
Spiko'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 #
[STAR CRITICAL] Not a spot DEX oracle. Spiko Oracle contract receives NAV data from CACEIS fund administrator via Spiko oracle-operator relayer. Published via publishPrice(uint48 timepoint, uint208 price) gated by restricted() modifier (ORACLE role). No DEX pool consulted. No AMM price. No flash-loan manipulation vector. Issuer-attested NAV is the most manipulation-resistant oracle design for RWA tokens.

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.
