Flash loan >$10M targeting protocol tokens

USDD (Decentralized USD)'s assessment for RD-F-100 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Flash loan targeting signal has limited applicability to USDD's architecture. USDD ERC-20 is not listed as a borrowable asset on Aave V3 or Balancer (data cache borrow.present: false). USDD's PSM design (1:1 USDC/USDT swap) is not a flash-loan-exploitable surface in the classic oracle-manipulation sense. TRON flash-loan infrastructure does not replicate EVM flash-loan patterns. No flash-loan targeting USDD contracts found in accessible EVM public records. Current architecture structurally limits flash-loan attack surface.
