Code divergence from upstream (%)
Save (formerly Solend)'s assessment for RD-F-129 — scored red on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Substantial divergence estimated >50% from upstream. Documented additions: multi-pool architecture (13+ isolated pools vs. upstream single-pool), custom interest-rate models per pool, custom liquidation engine, Pyth/Switchboard oracle integration (vs. upstream simpler price mechanism), SLND governance integration, and numerous bug fixes. The upstream was never deployed to mainnet as a production protocol — Solend is the production implementation with extensive divergence.
