What we observed
On May 17, 2026 at 23:29–23:42 UTC our RTT oracle detected a severe MEV stress event on Base.
Timeline:
23:29:43 UTC — Base P99 RTT: 52ms → 739ms (14x spike)23:30:10 UTC — Revert ratio: 0.19 → 0.5623:39:35 UTC — Peak: 61.36% of all Base transactions reverted23:41:52 UTC — Full sequencer stall (P99 = 5000ms timeout)
RTT spike led revert wave by 27 seconds.
Why it matters for Exactly
Exactly Finance's fixed-rate lending on Base is vulnerable to sequencer stall. During a 61% revert event, maturity settlements, liquidations and interest accruals compete in toxic mempool conditions. A 27-second warning enables protocol circuit breakers before cascade.
What we built
Phoenix Zero — 2-second RTT oracle, Base/Arbitrum/Optimism/ZKSync.
