Mixer withdrawal → protocol interaction

Save (formerly Solend)'s assessment for RD-F-090 — scored gray on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Mixer-withdrawal to protocol interaction signal. Tornado Cash is EVM-only (not applicable to Solana). Railgun operates on Solana but requires a licensed Chainalysis/TRM Solana TI feed for attribution. T-09 phase-2 signal. No public attribution report links recent mixer-adjacent activity to Solend/Save program `So1endDq2YkqhipRh3WViPa8hdiSpxWy6z3Z6tMCpAo`. Solana flash-loan provider role creates a broad attack-capital surface but no current mixer-to-protocol interaction detected in available public data.
