rubric v1.7.0

TWAP window duration

USDD (Decentralized USD)'s assessment for RD-F-054 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Not applicable to USDD's oracle design. USDD uses Chainlink/WINkLink push-model aggregated feeds (not DEX TWAP-based oracles). The OSM introduces a governance-configurable time delay (analogous in purpose to TWAP delay), but the underlying oracle source is an off-chain aggregated price feed, not a TWAP window. TWAP window duration is not a relevant parameter for this oracle architecture.

Methodology #

For each DEX-TWAP oracle, measure the TWAP window duration in minutes; flag any window < 30 minutes as high risk.
