TVL concentration (top-10 wallet share)

Sky Lending (formerly MakerDAO)'s assessment for RD-F-064 — scored gray on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Top-10 vault owner TVL concentration not computed. CDP vault architecture requires on-chain Vat urn enumeration; data not available in cache. PSM contract holds all USDC in a single address — a concentration signal for the ~33% PSM slice.

Detail #

DefiLlama data cache does not include per-vault holder distribution. On-chain enumeration of Vat urn positions was not completed within time budget. The PSM (LitePSM) holds USDC in a single contract address which concentrates ~32.9% of collateral TVL in one address. Without completing the urn enumeration, a precise top-10 share percentage cannot be assigned.
