}HIP-3 Backstop
Health overview of all observed HIP-3 backstops
Combined principal flow and observed on-chain activity for every HIP-3 backstop address (0x4000…00 + dex_index). One row per dex with at least one observed fill at its backstop address. Sorted by fill_count descending.
Backstop discovery. Backstop addresses are inferred by scanning the remote hip3_fills table for users matching ^0x4000…0[0-9a-f]+$ and taking argMax(addr, count) per dex_id. The mapping is cached in-memory for 5 minutes. A dex with zero observed backstop fills will not appear here.
Latency. 1–2 s on a cold cache (cache miss + N remote queries), under 50 ms when warm.
