★ Contract unverified on Etherscan/Sourcify
Jito's assessment for RD-F-046 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
[★] On-chain programs: open source and verified via solana-verify against GitHub release commits — green baseline. Yellow due to: (a) March 2024 unilateral mempool disable by Jito Labs without DAO vote — discretionary admin action over off-chain block engine; (b) Jito-Solana validator client (off-chain binary on ~90% of Solana stake) is not verifiable on any explorer. The off-chain MEV infrastructure represents significant unverifiable discretionary admin power. JIP-4 authorized subsequent validator blacklisting but did not retroactively ratify the mempool disable itself.
