Admin/upgrade transaction in mempool
Jito's assessment for RD-F-102 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Jito DAO upgrade authority (4ivLcnNLhe4cKdpV9b4jyEmxgbYWFgktHcTyyBvYavsD) controls on-chain program upgrades via Realms. No upgrade tx pending outside governance-approved proposals as of 2026-04-29. HOWEVER: the dominant Jito risk vector is off-chain. Jito Labs unilaterally disabled the block engine mempool on 2024-03-09 — a major operational action affecting all JitoSOL stakers' MEV yield — with zero on-chain footprint. This is structurally undetectable by the RD-F-102 signal. Jito Labs' BAM system (launched July 2025) also involves off-chain infrastructure changes not captured by on-chain mempool monitoring. Signal is applicable to on-chain upgrade txs but the most material risk is off-chain. v1 phase-2 signal; Solana mempool listener required (Solana TPU pipeline differs from EVM mempool).
