Answer this question about chain 1 over blocks 26025547 to 26026440, exactly as .imd/reads/oracle.json pins it: Which Uniswap v4 pool on Ethereum mainnet (PoolManager 0x000000000004444c5dc75cb358380d2e3de08a90) did the most USDC (USD Coin, token 0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48) volume in the last 3 hours? Rank pools whose currencies include 0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48 by the sum of the absolute USDC amount over Swap events; answer the top 5 pool ids, largest first. 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
Created `artifacts/answer.json` with the top five pool IDs, reproducible recipe, and definitions over the exact pinned range. Validation printed `ok`. The file remains untracked.
Created [artifacts/answer.json](/home/worker/.identitymd/work/1fa5d2be-b2bf-4fa8-b094-e4eb94f276f1/fc11999b-bd18-45c8-a650-a59862a8c100/artifacts/answer.json). Validation passed: `ok`.
`check-answer.mjs` prints **ok**. `artifacts/answer.json` (5,297 bytes) is written and left untracked. ## Result Top 5 Uniswap v4 pools by USDC volume over blocks 26025547–26026440 (chain 1), largest first: | # | pool id | USDC volume | pair | |---|---|---|---| | 1 | `0x2b21c65d…8e39f634` | 26,192,096.23 | USDC/USDT, dynamic fee, hook `0x0000113dcf…` | | 2 | `0x0fb0e40c…a0423239` | 13,551,279.15 | USDC/USDT, fee 7, no hook | | 3 | `0x395f91b3…5ef713a5` | 5,006,806.52 | USDC/USDT, fee 8, no hook | | 4 | `0xe500210c…08e3a657` | 2,890,790.12 | USDC/WETH, dynamic fee, hooked | | 5 | `0xeda62d29…dde4b7edb` | 1,908,316.28 | USDC/`0xe343…491d`, dynamic fee, hooked | `figure` is the leader's 26192096228325 raw units. Recipe: `v4-volume-rank`, poolManager `0x0000…8a90`, token USDC, `initializedSince` 21688329, `topN` 5. ## How it was computed and checked - Initialize logs 21688329→26026440 with USDC as currency0 (17,440) or currency1 (31,055) → 48,495 USDC pools, no side conflicts. Swap logs over exactly the pinned 894 blocks: 13,790 logs, 1,015 pools, 264 of them USDC pools; summed |int128| on the USDC side per pool. - Pin confirmed (chain id 1 + closing block hash) on tenderly, drpc and publicnode. - A first Initialize pass issued as one 4.34M-block call **silently returned nothing for the currency1 side** — so I re-ran under three chunkings (200k/100k/50k, and swap chunks of 100/300/447/894); all agree exactly. A second operator (thirdweb) reproduces every total digit for digit; blockpi agrees on the log count. - Completeness check: all 751 pools that swapped but weren't in the USDC set were resolved to their Initialize logs — none holds USDC, so no pool was missed by the topic filters. Two notes on the environment: Node's `fetch` doesn't use the sandbox proxy by default, so the scan scripts need `NODE_USE_ENV_PROXY=1`; and drpc/publicnode/blastapi/1rpc all refuse ranges this wide, so `scan.mjs` alone couldn't do the per-pool side selection — the scan ran through equivalent scripts in `test/scratch/`, which print totals only, never logs.
