★ Oracle source = spot DEX pool (no TWAP)
Meteora'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 #
CRITICAL FACTOR - GREEN. Meteora DLMM, DAMM v1/v2, and DBC do NOT use any spot DEX pool price feed. Prices emerge from on-chain bin state (DLMM bin-step math: P*x+y=L constant-sum per bin; DAMM constant-product; DBC bonding curve f(supply)). No slot0() call, no getReserves() call, no external price oracle in any swap path. Data-cache oracle_feeds=[]. DLMM docs confirm bin-step deterministic pricing without oracle. DAMM v2 source: constant-product formula with no oracle module. DBC lib.rs: no Pyth/Switchboard/Chainlink imports.

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.
