Answer this question about chain 56 over blocks 123032397 to 123040398, exactly as .imd/reads/oracle.json pins it: Which Uniswap v4 pool on BNB Smart Chain did the most native BNB volume in the last hour? Write only artifacts/answer.json: the typed answer (bytes32[]) and the recipe that reproduces it.
VERDICT: paths and tree verified; no suite was run for this kind of work
Done. `artifacts/answer.json` is written and validated. ## Answer **Leader: pool `0xdb4c4d91f12ce76f5c9ac0eae193cf3b4d6684cd5f09bf35d03dd9ae6d8a43b1`** (BNB ⇄ `0xc8fb80fcc03f699c70ff0cc08c09106288888888`) with **662.539347200228460915 BNB** across 816 swaps in blocks 123032397–123040398. Runner-up did 191.0 BNB, so the lead is not marginal. Recipe filed: `v4-volume-rank` with `poolManager 0x28e2ea090877bf75740558f6bfb36a5ffee9e9df`, `token 0x0…0` (native BNB), `initializedSince 45970610`, `topN 5` — catalogue parameters only, nothing extra. ## How it was computed 1. **Swaps**: `eth_getLogs` for the v4 `Swap` topic on the PoolManager over the pinned window, 500-block chunks → 29,451 swaps over 1,213 pool ids; `|amount0|` summed per id. 2. **Native pools**: `eth_getLogs` for `Initialize` with `topic2 (currency0) = 0x0` from block 45,970,610 to 123,040,398 in 9,999-block chunks (7,708 requests, range halved on refusal, errors never treated as empty) → 20,260 native-BNB pools, 750 of them active in the window. 3. **Rank** those 750 by summed `|amount0|`, descending, ties by ascending id. ## Verification - Pinned closing hash and `eth_chainId 0x38` confirmed on six endpoints. - The whole swap scan was rerun on an **independent operator set** (thirdweb + swiftnodes vs sentio/fastnode/blockmachine): same 29,451 swaps, same 1,213 pools, byte-identical per-pool sums. - Top-5 pools' `Initialize` logs re-read from the second endpoint set: all show `currency0 = 0x0`. - Guard against a missed `Initialize` flipping the ranking: all **119** pools excluded as non-native whose raw `|amount0|` still exceeded the leader were checked against swap receipts — 116 show an ERC20 `Transfer` of exactly `|amount0|` (or `|amount0|` split by a hook fee) in/out of the PoolManager; the remaining three trade at ≤1e-5 USDT per unit of currency0, which rules out BNB. That last trio rests on a price argument, not a log match — stated plainly here and in `notes`. ## Deliberately not done - No second full-history `Initialize` scan on a different operator: no BSC public endpoint reachable here serves ≥10k-block archive `eth_getLogs` besides the three used (drpc, publicnode, 48.club, tatum, 1rpc, blastapi, nodereal, pocket all refuse), and a 1,000-block-chunk rerun would be ~77k requests. The targeted 119-pool disproof above covers the failure mode that would change the answer. - Nothing outside `artifacts/answer.json` was created; scratch code lives in `test/scratch/` and the artifact is untracked (`artifacts/` is in `.git/info/exclude`).
