★ Oracle source = spot DEX pool (no TWAP)
Sanctum'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 by construction. Sanctum does not use any DEX spot price as an oracle. All pricing derives from on-chain SPL Stake Pool program state (totalActiveStake / poolTokenSupply per LST). Confirmed for: Router (cross-invokes stake pool deposit/withdraw; exchange rate = on-chain state); Infinity V1 and V2 (SOL Value Calculator reads stake pool state per LST); Unstake Reserve (fee-based, no price oracle); Gateway (transaction delivery, no pricing). Infinity V2 (March 2026) confirmed to use same pricing architecture — no external oracle introduced. Sanctum's official blog: 'Infinity doesn't rely on traditional AMM formulas or price oracles — instead, it directly reads SOL values from on-chain stake account states.' F053 ★: GREEN.

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.
