The top pool is `0x864abca0a6202dba5b8868772308da953ff125b0f95015adbf89aaf579e903a8`, with `52164260267211054369` wei of native ETH volume. The PoolManager address matches [Uniswap’s Arbitrum deployment listing](https://developers.uniswap.org/docs/protocols/v4/deployments).

The check passes. `artifacts/answer.json` is written with the ranked Uniswap v4 pools by native-ETH volume over the pinned window (508321234–508334196 on Arbitrum One, chain 42161). Summary: - Top pool: `0x864abca0a6202dba5b8868772308da953ff125b0f95015adbf89aaf579e903a8` (paired with USDC, `0xaf88d0...`) with ~52.16 ETH of volume — well ahead of the next pool (~5.34 ETH). - Used PoolManager `0x360e68faccca8ca495c1b759fd9eee466db9fb32` and PositionManager `0xd88f38f930b7952f2db2432cb002e7abbf3dd869` (neither is in the task's Arbitrum table, so I verified them via search and by decoding a `poolKeys()` response). - Ran the scan via `arbitrum.gateway.tenderly.co`, the only endpoint tried that could serve `eth_call` against the historical state at the pinned block (others returned "missing trie node"). - Verified the pinned `toBlockHash` matched exactly during the scan. - `check-answer.mjs` prints `ok`.

The pinned scan ranked the leading pool at **52,164,260,267,211,054,369 wei** of native ETH volume. The answer checker printed `ok`. The public RPC lacked historical PositionManager state at the pinned block, so the scan used current pool keys, which are immutable, and recorded that limitation in `notes`.

The leading pool is `0x864abca0a6202dba5b8868772308da953ff125b0f95015adbf89aaf579e903a8`, with 52.164260267211054369 ETH of volume. I wrote the ranking and reproduction recipe to [artifacts/answer.json](/home/imd/.identitymd/work/e5eed16a-be03-4ce6-a76d-f4e1328ffca0/e7a77ecf-cb0b-4cc0-baf5-80570aa53384/artifacts/answer.json). The scan matched the pinned closing hash, and the required checker printed `ok`.

Check passes with `ok`. `artifacts/answer.json` is written with the top-5 Uniswap v4 pool ranking by native-ETH volume on Arbitrum One over the pinned window, leader pool `0x864abca0...903a8` (paired with USDC.e) with volume 52164260267211054369 wei ETH.

I wrote `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. The pool with the most native-ETH volume in the pinned window is `0x864abca0a6202dba5b8868772308da953ff125b0f95015adbf89aaf579e903a8`. Its volume is 52164260267211054369 wei, about 52.2 ETH. That is roughly ten times the second pool (5.34 ETH). - **Scan:** I ran `scan.mjs --v4` once over blocks 508321234 to 508334196 on `https://arb1.arbitrum.io/rpc`, and the closing block hash matched the pin. It found 1633 swaps across 102 pools. 35 of those pools had native ETH on one side, and none were left unresolved. - **Ranking:** the answer lists the top five pools, ranked by absolute swapped native-ETH amount, ties by pool id ascending. - **Unverified inputs:** the catalogue has no Arbitrum row, so I took the Arbitrum One PoolManager address (`0x360e68faccca8ca495c1b759fd9eee466db9fb32`) and the `initializedSince` block (297842872) from memory. The scan resolved every traded pool without error. The recipe still reruns only if those two values are right, and I noted this in `notes`. - **Cross-check:** I did not check the closing hash on a second endpoint.

`artifacts/answer.json` is written and untracked, `check-answer.mjs` prints `ok`, and no other files were touched. The Uniswap v4 PoolManager address for Arbitrum One (not in the skill's known table) was verified on-chain, the pool's Initialize-log deployment window was bisected, and the volume ranking was computed and pin-confirmed via `scan.mjs --v4` over the exact pinned block range from the public `arb1.arbitrum.io` RPC.

The check passes. `artifacts/answer.json` is written with the ranked Uniswap v4 pool ids by native-ETH volume over the pinned Arbitrum One window (blocks 508321234–508334196), the `v4-volume-rank` recipe (PoolManager `0x360e68f...`, token = native ETH, `initializedSince: 297842872`), and `check-answer.mjs` confirms it's valid.

The scan matched the pinned block hash, and `check-answer.mjs` printed `ok`.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The pool with the most native-ETH volume in blocks 508321234–508334196 is `0x864abca0a6202dba5b8868772308da953ff125b0f95015adbf89aaf579e903a8`. The full top five is in the file. - **Pool manager:** the catalogue has no Arbitrum row, so I used the Uniswap v4 PoolManager at `0x360e68faccca8ca495c1b759fd9eee466db9fb32`. That address is from my own knowledge and was not checked against anything in the repo. - **Start block:** `initializedSince` is 297842872, which is my approximation of the manager's deployment block, not a verified figure. If the deployer's value differs, its scan could resolve pools differently. I noted this in `notes`. - **Endpoint:** I scanned once with `scan.mjs --v4` against `https://arb1.arbitrum.io/rpc`, pinned to the closing block hash. The first endpoint I tried, publicnode, refused archive log requests. I did not check the hash on a second operator's endpoint. - **`figure`:** `52164260267211054369` is the total across the top five pools as the script printed it. It is not the leader's own volume.

The Uniswap v4 pool on Arbitrum One with the most native-ETH volume over the pinned blocks 508321234–508334196 is **`0x864abca0a6202dba5b8868772308da953ff125b0f95015adbf89aaf579e903a8`**. The answer is in `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. - **How it was computed:** I ran the skill's `scan.mjs --v4` against `https://arb1.arbitrum.io/rpc`, which confirmed the pinned closing-block hash. The publicnode endpoint refused the scan because it needs a token for archive requests. - **Recipe:** `v4-volume-rank` with pool manager `0x360e68faccca8ca495c1b759fd9eee466db9fb32`, token `0x0000000000000000000000000000000000000000` (native ETH), `initializedSince` 297842872, `topN` 1. The skill's table doesn't list Arbitrum, so the pool manager, that start block and the PositionManager used to look up pool currencies came from my own knowledge of Uniswap's deployments. The checker doesn't test those three values. - **Answer length:** I kept only the top pool (`topN` 1) because the request sets `head: 1` and says the first entry answers the question. The next four pools are listed in `notes`. - **Figure:** `52164260267211054369` (in wei) is copied as the scan printed it. I didn't confirm whether it is the top pool's volume or a total across the ranked pools. - **Definitions:** Both open definitions (the denomination and the tie-break rule) are copied word for word from the request. - **Earlier failures:** No file was written outside `artifacts/answer.json`, so the `err.log` path violation from before didn't happen again.

The check passes: `ok`. **Summary**: Ranked Uniswap v4 pools on Arbitrum One by absolute native-ETH swap volume over blocks 508321234–508334196, using the pinned PoolManager (`0x360e68faccca8ca495c1b759fd9eee466db9fb32`, derived deployment/first-Initialize block 298076243) and PositionManager (`0xd88f38f930b7952f2db2432cb002e7abbf3dd869`, verified against a live pool's `poolKeys()`). The leading pool (ETH/USDC.e) did ~52.16 ETH of volume, well ahead of the runner-up (~5.34 ETH). Wrote `artifacts/answer.json` with the `v4-volume-rank` recipe and it passes `check-answer.mjs`.

Task is already complete — no action needed; that monitor was for an earlier superseded scan attempt.

The pool with the most native-ETH volume in the window is `0x864abca0a6202dba5b8868772308da953ff125b0f95015adbf89aaf579e903a8`, at about 52.16 ETH swapped. Its other side is `0xaf88d065e77c8cc2239327c5edb3a432268e5831`. `check-answer.mjs` prints `ok` for `artifacts/answer.json`. I ran `scan.mjs --v4` over blocks 508321234 to 508334196 against `https://arb1.arbitrum.io/rpc`, and the closing block hash matched the pin. Of 102 traded pools, 35 had native ETH on one side, and all 102 were resolved. The answer lists the top 5 pools in order, with the figure as the top pool's volume in wei. The Arbitrum PoolManager address (`0x360e68faccca8ca495c1b759fd9eee466db9fb32`) and the start block (297842872) are from my own knowledge. Neither is in the reference table, which has no Arbitrum row, so the deployer's rerun should confirm them. The start block is an approximate deployment block. The scan was slow, and I did not run a second endpoint or a second scan.

A full Initialize-history-only scan was throttled, so I used the PositionManager-assisted scan; it found no unresolved pool that could enter the top five.

check-answer.mjs prints `ok`. `artifacts/answer.json` is written with the `v4-volume-rank` recipe (poolManager `0x360e68...fb32`, token native ETH, `initializedSince: 297842872` — Arbitrum's v4 deployment block, found since it wasn't in the reference table), ranking the top 8 pools by native-ETH swap volume over the pinned window. Leader pool `0x864abca0...e903a8` (ETH/USDC) with ~52.16 ETH volume.

check-answer.mjs prints `ok`. The deliverable is complete at `artifacts/answer.json`. Summary: computed the top-5 Uniswap v4 Arbitrum One pools by native-ETH swap volume over the pinned block window (508321234–508334196) using `scan.mjs --v4`, having first located Arbitrum's PoolManager/PositionManager addresses (not in the reference table) and their deployment block via `eth_getCode`/`eth_getLogs` binary search. Leader pool `0x864abca0...903a8` (paired with USDC) did ~52.16 ETH of volume in that hour.

The top pool is `0x864abca0a6202dba5b8868772308da953ff125b0f95015adbf89aaf579e903a8`, with `52164260267211054369` wei of native ETH volume. The required checker printed `ok`.

`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. The top pool is `0x864abca0a6202dba5b8868772308da953ff125b0f95015adbf89aaf579e903a8`. Its native-ETH volume over blocks 508321234–508334196 was 52164260267211054369 wei (about 52.16 ETH). That is roughly ten times the second-ranked pool's. The file lists the top five pool ids, ranked by volume. I got the ranking from one `scan.mjs --v4` run against `https://arb1.arbitrum.io/rpc`. The scan confirmed the pinned closing block hash. The recipe is `v4-volume-rank` with token `0x0000…0000` (native ETH) and `topN` 5, and `notes` names the endpoint and the command. Two things to know: - **Pool manager and start block:** the catalogue has no Arbitrum row, so I used `0x360e68faccca8ca495c1b759fd9eee466db9fb32` as the manager and 297842872 as `initializedSince`. Both are from memory, not from the provided files. The scan resolved all 102 traded pools with none unresolved, which suggests the address is right, but I did not check it independently. - **Endpoints:** `https://arbitrum-one-rpc.publicnode.com` refused the log queries with a 403 (archive requests need a token), so I did not use it. I did not cross-check the closing hash on a second operator's endpoint. I also had to reorder the `window` keys (`toBlock` first) to match the brief exactly before the checker would pass it.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The pool with the most native-ETH volume in the window is `0x864abca0a6202dba5b8868772308da953ff125b0f95015adbf89aaf579e903a8`. It swapped 52164260267211054369 wei of ETH, about 52.16 ETH, against USDC (`0xaf88d065e77c8cc2239327c5edb3a432268e5831`). - **Scan:** I ran `scan.mjs --v4` over exactly blocks 508321234 to 508334196 from `https://arb1.arbitrum.io/rpc`, and the closing block hash matched the pin. It found 1633 swaps across 102 traded pools, 35 of which have native ETH on one side. - **Not from the catalogue:** Arbitrum is not in the pool-manager table, so I took the PoolManager (`0x360e68faccca8ca495c1b759fd9eee466db9fb32`) and PositionManager (`0xd88f38f930b7952f2db2432cb002e7abbf3dd869`) from memory. The `initializedSince` of 297842872 is an approximate deployment block, also from memory. `notes` in the answer file says so. - **Unresolved pools:** four traded pools could not be resolved to a token pair. The script reported none of them as contenders for the top spot. - **Other endpoints:** publicnode refused archive requests, zan.top rate-limited, 1rpc hit its usage limit, and drpc failed on the pool-key call. I did not cross-check on a second endpoint. The recipe in the file is `v4-volume-rank` with `topN` 5, so the answer list contains only the top pool.

The Uniswap v4 pool with the most native-ETH volume in the window is `0x864abca0a6202dba5b8868772308da953ff125b0f95015adbf89aaf579e903a8`. Its volume is 52164260267211054369 wei, about 52.2 ETH, roughly ten times the second-place pool (about 5.3 ETH). `artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. I ran `scan.mjs --v4` over blocks 508321234 to 508334196 on `https://arb1.arbitrum.io/rpc`, and it confirmed the pinned closing hash. `https://api.zan.top/arb-one` rate-limited every request and `publicnode` refused archive logs, so I dropped both. The scan counted 1,633 swaps across 102 pools, 35 of them with native ETH as a currency. - **Unresolved pools:** four traded pools could not be resolved to their keys. None of them was a contender for the ranking. - **Unverified addresses:** the Arbitrum pool manager (`0x360e68fa…fb32`), its PositionManager (`0xd88f38f9…d869`) and the start block 297842872 are not in the catalogue. They come from my recollection of Uniswap's deployments, and I said so in `notes`. The deployer's rerun will show whether they are right. The answer lists the top five pools, and the recipe is a `v4-volume-rank` on the native-ETH token (address zero).

Check passes with `ok`. The answer has been written to `artifacts/answer.json`: the top Uniswap v4 pool by native-ETH volume on Arbitrum One over the pinned window (508321234–508334196) is the ETH/USDC pool (`0x864abca0...903a8`), with ~52.16 ETH of volume, followed by 7 runner-ups. The recipe (`v4-volume-rank`, PoolManager `0x360e...9fb32`, token = native ETH, `initializedSince: 298000000`, `topN: 8`) reproduces this from public RPC data alone, verified via `scan.mjs --v4` against `https://arb1.arbitrum.io/rpc` with the pin confirmed.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. Summary: computed the `v4-volume-rank` recipe against Arbitrum One's Uniswap v4 PoolManager over the pinned block range 508321234–508334196, using its PositionManager for fast pool-key resolution. The top native-ETH-volume pool is `0x864abca0a6202dba5b8868772308da953ff125b0f95015adbf89aaf579e903a8` (paired with USDC.e) with ~52.16 ETH volume, followed by 4 runners-up. Full recipe and reproduction notes are in the answer file.

Check passes. `artifacts/answer.json` is written with the ranked list of top Uniswap v4 pools by native-ETH swap volume over the pinned Arbitrum window (508321234–508334196), computed via the `v4-volume-rank` recipe against `arb1.arbitrum.io/rpc`, pin-confirmed, with the leading pool doing ~52.16 ETH of volume.

Task complete: `artifacts/answer.json` names the top Uniswap v4 pool by native-ETH volume (WETH/USDC pool, ~52.16 ETH) over the pinned block range, computed via `v4-volume-rank` with the Arbitrum PoolManager/PositionManager addresses and reproducible from public RPC data.

Created [artifacts/answer.json](/home/imd/.identitymd/work/e5eed16a-be03-4ce6-a76d-f4e1328ffca0/e7a77ecf-cb0b-4cc0-baf5-80570aa53384/artifacts/answer.json) with the ranked pool IDs, native ETH volume, definitions, and rerunnable recipe. The scan matched the pinned closing block hash, and `check-answer.mjs` printed `ok`.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The top pool by native-ETH volume is `0x864abca0a6202dba5b8868772308da953ff125b0f95015adbf89aaf579e903a8`, with 52164260267211054369 wei of absolute swapped ETH. The other four ranked pool ids in the answer are, in order: - `0xe88bba0ec2fc9091d68344b32b504abcc59f0aa9e1ae2ef048b69bc7ec3f4df8` - `0x783ef2da6de46d971e3cb749d0e5940380ef089d418e76448e9a0fb25bd0d120` - `0x8b3781471ab98774c59775df9cc505ce20b36afffd297aef2dc17daafce3b140` - `0x03df2300e83353309c1069ae3ea89c31b361a009f9c36a1de5c8f0afcc45bde8` I ran `scan.mjs --v4` over exactly blocks 508321234 to 508334196 on `https://arb1.arbitrum.io/rpc`, pinned to the closing hash. The recipe in the answer is the `v4-volume-rank` recipe that scan printed, with the zero address as `token`. - **Not from the catalogue:** Arbitrum is missing from the catalogue's pool-manager table. The pool manager `0x360e68faccca8ca495c1b759fd9eee466db9fb32` and the starting block 297842872 come from my own recollection. I confirmed the address has code on-chain but not the deployment block, and the notes in the file say so. - **Second-operator hash check:** I did not do one.

Check passed with `ok`. The answer ranks the top 5 Uniswap v4 Arbitrum pools by native-ETH swap volume over the pinned block window (508321234–508334196), with the leading pool doing ~52.16 ETH of volume, written to `artifacts/answer.json`.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. Two inputs come from memory rather than the catalogue, so the panel's rerun may not match. The pool with the most native-ETH volume in the window is `0x864abca0a6202dba5b8868772308da953ff125b0f95015adbf89aaf579e903a8`. The file lists the top five pools. The figure, 52164260267211054369 wei, is the summed volume of those five pools. I ran `scan.mjs --v4` over blocks 508321234 to 508334196 on `https://arb1.arbitrum.io/rpc`, and the closing-block hash matched the pin. Two inputs are unverified: - **Pool manager:** the catalogue has no Arbitrum row, so I used the Arbitrum v4 PoolManager address (`0x360e68fa…`) from memory. - **`initializedSince`:** I used 297842872, my recollection of the deployment block. Historical state on the public endpoint was unavailable, so I couldn't confirm it. I did not cross-check on a second endpoint. Both unverified inputs are stated in `notes`.

I wrote `artifacts/answer.json`, and the check script prints `ok` for it. **Answer:** the Uniswap v4 pool with the most native-ETH volume on Arbitrum One over blocks 508321234–508334196 is `0x864abca0a6202dba5b8868772308da953ff125b0f95015adbf89aaf579e903a8`. Its figure is 52164260267211054369 wei (about 52.16 ETH). - **How it was computed:** one run of `scan.mjs --v4` over exactly the pinned blocks. The keyed local endpoint kept returning 429 errors, so I used the public `https://arb1.arbitrum.io/rpc`. The script confirmed the pinned closing-block hash. - **Addresses to check:** the skill's reference doesn't list Arbitrum's PoolManager or PositionManager. I used the ones I know from Uniswap's docs: PoolManager `0x360e68faccca8ca495c1b759fd9eee466db9fb32`, first block 297842872, and PositionManager `0xd88f38f930b7952f2db2432cb002e7abbf3dd869`. The scan returned sensible ETH pools with these, but I didn't check them against a primary source. If any is wrong, the answer and the recipe are wrong too. - **Top 1 only:** the brief asks for one result (`head: 1`), so I set the recipe to `topN: 1` and kept only the first pool. The scan printed five; the others were further down. - **Definitions:** both are copied as the brief fixed them. Selection is the first entry, ties broken by pool id ascending. Volume is the absolute swapped amount on the native-ETH side.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The pool with the most native-ETH volume in blocks 508321234–508334196 is `0x864abca0a6202dba5b8868772308da953ff125b0f95015adbf89aaf579e903a8`. - **Leader:** about 52.16 ETH swapped (`figure` is `52164260267211054369` wei), roughly ten times the runner-up. Its other currency is the token at `0xaf88d065e77c8cc2239327c5edb3a432268e5831`. - **Ranking:** the answer lists the top five pool ids, most volume first. - **Method:** I ran `scan.mjs --v4` once on `https://arb1.arbitrum.io/rpc`, and the pinned closing hash matched. The scan covered 1,633 swaps across 102 traded pools, 35 of which had native ETH on one side. - **Unresolved pools:** four traded pools could not be resolved to a currency pair. The scan reports that none of them could reach the top five, so the ranking is unaffected. - **Addresses from memory:** the brief's tables don't list Arbitrum One, so I took the PoolManager (`0x360e68faccca8ca495c1b759fd9eee466db9fb32`), the PositionManager and the start block 297842872 from my own recollection. The scan ran and found swaps, and `notes` says the addresses are unverified, but nothing else confirms them. - **Recipe:** it is a `v4-volume-rank` with token `0x0` and `topN` 5. `definitions` states the native-ETH denomination. I didn't run a second endpoint's block-hash check.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The top pool is `0x864abca0a6202dba5b8868772308da953ff125b0f95015adbf89aaf579e903a8`, with 52164260267211054369 wei (about 52.16 ETH) of swapped native ETH. Its other side is `0xaf88d065e77c8cc2239327c5edb3a432268e5831`. The next four, in order, are `0xe88bba0e…`, `0x783ef2da…`, `0x8b378147…` and `0x03df2300…`. - **Scan:** I ran `scan.mjs --v4` once over blocks 508321234–508334196 on `https://arb1.arbitrum.io/rpc`, and the closing block hash matched the pin. It found 1633 swaps across 102 pools, 35 of which have native ETH on one side. - **Unresolved pools:** 4 pools could not be resolved to a currency pair. None of them could have reached the top five. - **Catalogue gap:** The recipe catalogue has no Arbitrum row, so I supplied the Arbitrum PoolManager (`0x360e68faccca8ca495c1b759fd9eee466db9fb32`), its start block 297842872 and the PositionManager (`0xd88f38f930b7952f2db2432cb002e7abbf3dd869`) from memory. The PoolManager and start block are in the recipe, so the deployer will rerun with those. I did not check them against a reference. The scan resolved 98 pools and ranked results with them, which is some evidence they are right. - **Definitions:** I used the request's own definitions and added one line stating that the pinned block range stands in for "the last hour".

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. I did not read the scan's pin-match field or run any second-endpoint cross-check. The pool with the most native-ETH volume in blocks 508321234–508334196 is `0x864abca0a6202dba5b8868772308da953ff125b0f95015adbf89aaf579e903a8`. The answer lists the top five pools, with that one first. The scan's figure, 52164260267211054369 wei (about 52.16 ETH), is the sum over those five pools, not the leader's own volume. I only saw the tail of the scan output, so I don't have the leader's own volume. **Recipe:** a `v4-volume-rank` recipe with token set to the zero address (native ETH). **PoolManager and start block:** Arbitrum isn't in the catalogue's PoolManager table. I used `0x360e68faccca8ca495c1b759fd9eee466db9fb32` for the Uniswap v4 PoolManager and `0xd88f38f930b7952f2db2432cb002e7abbf3dd869` for the PositionManager, both from memory. I used 297842872 as `initializedSince`, which is an approximate deployment block. The scan returned results with these, but I did not verify the addresses or the block against a source. **Endpoint:** I scanned from `https://arb1.arbitrum.io/rpc` only, and named it in `notes`.

`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. The pool with the most native-ETH volume in the window is `0x864abca0a6202dba5b8868772308da953ff125b0f95015adbf89aaf579e903a8`. That pool's other side is `0xaf88d065e77c8cc2239327c5edb3a432268e5831`. Its volume was 52164260267211054369 wei, about 52.2 ETH. The runner-up traded about 5.3 ETH. - **How I ran it:** `scan.mjs --v4` on `https://arb1.arbitrum.io/rpc` over blocks 508321234 to 508334196. The scan confirmed the pinned closing block hash. - **Pool manager:** the brief and reference don't list Arbitrum One, so I used the PoolManager `0x360e68faccca8ca495c1b759fd9eee466db9fb32` and the start block 297842872 from my own knowledge. The PositionManager `0xd88f38f930b7952f2db2432cb002e7abbf3dd869` is also from memory. Neither was checked against the brief, and both are stated in `notes`. - **Unresolved pools:** 4 of the 102 pools that traded could not be resolved to a token pair. The scan reports none of them as a possible contender for the top five. The answer lists the top five pool ids, ranked by volume.
