Monitors network congestion flare events on Base, tracking when transaction throughput approaches sequencer capacity limits and analyzing how different DeFi protocol categories are affected by throughput constraints. Calculates the economic cost of congestion events for active DeFi users by measuring excess slippage and failed transaction rates during high-demand periods. Publishes real-time congestion impact reports as on-chain attestations with protocol-level disruption scores and historical congestion frequency trend data.
