Done. `artifacts/answer.json` is written and the checker prints `ok`. ## Answer **3625667567567567 wei** (~0.0036257 ETH) — the floor of 134149700000000000 / 37. ## How it was computed Scanned all 12,231 `OrderFulfilled` events from Seaport 1.5 and 1.6 over blocks 26019451–26026607, decoded each one's `offer`/`consideration` arrays, and kept the 37 that hold exactly one ERC-721 of `0xaa83…75e0` and no other NFT: 17 listing fills (priced as their consideration sum) and 20 bid fills (priced as the offer amount). Nothing was skipped — no bundles, no ERC-1155s, no other currency, no multi-item offers. `scan.mjs` couldn't do this reduction — `--sum data:N` reads flat 32-byte words and Seaport's items live in two nested dynamic arrays — so the decoder ran in `test/scratch/`, reusing that script's `keccak256` and its chunk-halving pattern, and printing only totals. ## The one judgment call 37 sales sit in 19 transactions but move only 32 NFTs. The gap is OpenSea's `matchOrders`: 5 trades emit **two** `OrderFulfilled` events for the same token id. For token 2560, the bid side offers 0.0034 WETH (consideration = NFT + 0.000034 OpenSea fee + 0.00017 royalty) while the listing side offers the NFT for 0.003196 WETH — exactly 0.0034 minus those fees. I counted both sides, because the brief defines a sale *per event* and gives each side its own price rule; that reading is mechanical and leaves nothing to invent. Deduplicating to 31 trades would require a tie-break rule the request never states, but it's a real alternative, so the figure it yields (3736119354838709) is recorded under `definitions` where a reader will see it. ## Verification - Pinned closing hash and `eth_chainId` confirmed on four independent operators. - Two independent confirmations on a second endpoint, one taking a completely different path — the collection's own 32 `Transfer` logs → the 20 blocks they touch → per-block `OrderFulfilled` — landing on the same 37 sales and the same sum, with every priced sale's identifier verified to have actually moved in that transaction (0 mismatches). - The recipe is `{kind: "panel", source}` because the brief sets `evidence: panel`; the checker rejects anything else under it, so the on-chain method is spelled out in `notes` instead. Both `artifacts/` and `test/scratch/` are untracked and nothing was staged.

I've written `artifacts/answer.json`, and the checker (`check-answer.mjs`) prints `ok`. The answer is **3625667567567567 wei**, about 0.003626 ETH. It counts every event as its own sale, as the brief's definition says. That includes a double-counting issue explained below that could split the panel. **How I got it** - I fetched every `OrderFulfilled` log from both Seaport contracts (1.5 and 1.6) over exactly blocks 26019451–26026607, in 500-block chunks that split in half if an endpoint refuses the range. The window had 12,231 of these logs. - I wrote my own Node script for this in `test/scratch/`, which isn't submitted. The provided `scan.mjs` can only sum fixed data fields, and it can't read the lists of offer and payment items inside each Seaport event. - The chain id was 1 and the closing block's hash matched the pinned one; I checked both on publicnode. publicnode then refused the log queries (it wants a token for old-block data), so the logs came from `rpc.flashbots.net/fast`. - 37 events qualified: 17 listing fills and 20 bid fills. There were no bundles, no fills paid in other tokens, and no listing fills with an empty payment list. The prices add up to 134149700000000000 wei, and that sum divided by 37, rounded down, is the answer. - Because the brief says `"evidence": "panel"`, the recipe is the `panel` kind. Its `source` field names the endpoint, the event topic, both Seaport addresses and the block range. **The double-counting issue.** When a seller accepts an OpenSea collection or item offer, the transaction emits two qualifying events: the buyer's bid (the full WETH price, e.g. 3.2e15) and the seller's matching order (the price minus fees, e.g. 3.008e15). The brief defines a sale as an event, so I counted both, and I say so in `definitions` and `notes`. A panel member who counts one sale per transaction would get a different, probably higher, average. I did not calculate that alternative figure. I did not run a second full scan, and I changed no files other than `artifacts/answer.json`.

`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. **Answer:** 3625667567567567 wei. That is 134149700000000000 wei across 37 qualifying sales, rounded down. - **How I computed it:** I fetched all 12,231 `OrderFulfilled` logs from Seaport 1.5 and 1.6 over blocks 26019451 to 26026607, from `https://ethereum-rpc.publicnode.com`. I decoded them by hand, since `scan.mjs` can't decode Seaport events. I kept fills with exactly one ERC-721 of the collection, paid in ETH or WETH, priced as the definitions say. No fill of the collection was dropped for an ineligible shape or payment token. - **Pin check:** the closing block hash matched the pin on publicnode and on `https://rpc.flashbots.net/fast`, and `eth_chainId` was 1. - **Recipe kind:** the brief says `"evidence": "panel"`, and the checker rejects any other kind for that. So the recipe is `panel` with the RPC URL and log filter as its source, not a rerunnable chain recipe. - **Key order:** the checker compares the window as an exact string, so its keys are in the brief's order (`toBlock`, `fromBlock`, `toBlockHash`). - **Scratch script:** the script is in `test/scratch/sales.mjs`, which is not submitted.

I wrote `artifacts/answer.json`. The average Shellmates sale price over blocks 26019451–26026607 is **3625667567567567 wei**, about 0.003626 ETH. `check-answer.mjs` prints `ok`. - **Sales:** 37 qualifying sales summed to 134149700000000000 wei, and the answer is that sum divided by 37, rounded down. No sales were excluded by the currency or shape rules. - **Scan:** I scanned all 12,231 `OrderFulfilled` logs from both Seaport contracts (1.5 and 1.6) over exactly the pinned blocks. I ran it from `https://ethereum-rpc.publicnode.com`, using my own script in `test/scratch/` because the provided `scan.mjs` can't decode Seaport's nested offer and consideration arrays. - **Pin:** the closing hash matched the pin on publicnode and also on `https://rpc.flashbots.net/fast`. - **Recipe kind:** the recipe is `panel`, because the brief has `"evidence": "panel"` and the checker refuses any other kind for it. The `source` URL names the endpoint and the scan parameters. The catalogue can't rerun this computation, so `notes` explains the method instead. - **`artifacts/answer.json`:** the file is untracked (`git status` was clean). The first `check-answer.mjs` run failed because I had `fromBlock` before `toBlock` in `window`. I reordered the keys to match the brief, and it then passed.

I wrote `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. The average sale price comes out at **3625667567567567 wei**, about 0.003626 ETH. - **Result:** 37 qualifying sales sum to 134149700000000000 wei, and that divided by 37, rounded down, gives the answer. - **Method:** I pulled the collection's ERC-721 `Transfer` logs over blocks 26019451–26026607, which gave 32 logs across 20 blocks. In those blocks I fetched Seaport 1.5 and 1.6 `OrderFulfilled` events, 73 in all. I decoded them by hand and applied the request's sale and price definitions. - **Double counting (your call):** 37 sales cover only 19 transactions and 32 `Transfer` logs. That is because a matched listing and bid for one token emits two `OrderFulfilled` events. The request says every qualifying event counts, so I counted both. Counting each token once would give a different average, and I noted the choice under `definitions`. - **Recipe:** the brief sets `"evidence": "panel"`, so I used the `panel` kind. It is the only kind the brief allows, and none of the chain recipes can express this filtered average. Its `source` is the RPC endpoint (`https://ethereum-rpc.publicnode.com`) I read from, and the notes describe the method. - **Verification gap:** `eth_chainId` and the closing block hash matched the pin on that endpoint. I did not check the hash on a second operator's endpoint. The scan script is a one-off in `test/scratch/`, not delivered.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. It is untracked and not force-added. - **Answer:** 3625667567567567 wei, about 0.0036 ETH. It is the sum of 134149700000000000 wei over 37 qualifying sales, rounded down. - **Sales:** 17 were listing fills and 20 were bid fills. No bundles, ERC-1155 fills, non-ETH/WETH fills or duplicate logs turned up. - **Window:** exactly blocks 26019451 to 26026607. The closing hash matched the pin on publicnode and again on rpc.flashbots.net. - **Scan:** all 12,231 `OrderFulfilled` logs from both Seaport contracts came from publicnode, in 500-block chunks. I decoded them with my own script in `test/scratch/sales.mjs`, not the provided `scan.mjs`. - **Recipe:** the brief says `"evidence": "panel"`, and the checker only accepts a `panel` recipe for that. The recipe is therefore `{kind: "panel", source: <publicnode URL plus the getLogs parameters>}`, and `notes` gives the full method. - **Repaired:** my first two decodes read the wrong word for the token address. The first run mis-sorted the fills and the second matched nothing. I fixed it with an address-per-word helper, and the answer above is from the fixed run. I did not check the decode against a second source.

I wrote `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. The average sale price of Shellmates over blocks 26019451 to 26026607 is **3625667567567567 wei**. - **Sales counted:** 37 qualifying sales, 17 listing fills and 20 bid fills, summing to 134149700000000000 wei. None were excluded as bundles or as non-ETH/WETH payments. - **How I computed it:** - I fetched the `OrderFulfilled` logs from Seaport 1.5 and 1.6 over exactly the pinned blocks from `https://ethereum-rpc.publicnode.com`. That gave 12231 logs with no duplicates. - I decoded the offer and consideration arrays myself, because `scan.mjs` can only sum or rank a single field, and applied the definitions in `oracle.json`. - This was one full scan. I did not run a second one. - **Pin check:** The chain id (1) and the closing block hash `0x8a84f5aa…` match on publicnode. The hash also matches on `https://rpc.mevblocker.io/fast`, a different operator. - **Recipe kind:** The brief says `"evidence": "panel"`, and `check-answer.mjs` requires the recipe to be `{kind: "panel", source}` for such briefs. The `source` is a URL naming the RPC and the log query, and `notes` has the full method. This means the recipe itself doesn't tell the deployer how to rerun the computation. That method is only in `notes`. - **Where the code is:** The decoding script is at `test/scratch/run.mjs`. It isn't part of the submission.

Done. `artifacts/answer.json` is written, passes the plane's check (`ok`), and sits untracked under `artifacts/` for the daemon to pick up. **Answer: 3625667567567567 wei** (~0.00363 ETH average sale price). How it was computed, per the brief's pinned definitions: - Confirmed chain id 1 and the pinned closing hash `0x8a84f5aa…cdec2` for block 26026607 on two independent operators (publicnode and flashbots) before scanning. - Scanned `eth_getLogs` for the `OrderFulfilled` topic on both Seaport 1.5 and 1.6 over exactly blocks 26019451–26026607 from `https://ethereum-rpc.publicnode.com`, and ABI-decoded each log's offer/consideration arrays in a scratch script (the skill's scan.mjs can only sum flat data words, so the nested-array decoding needed custom code in `test/scratch/`). - Of 12,231 OrderFulfilled logs in the window, 37 qualified: exactly one ERC-721 of the Shellmates collection, no other NFT, paid entirely in ETH or WETH — 17 listing fills (price = sum of all consideration amounts, fees included) and 20 bid fills (price = the single offer amount). All 37 were on Seaport 1.6; nothing was excluded as a bundle, ERC-1155, or other-token payment, and there were no zero-price fills. - Sum of prices 134,149,700,000,000,000 wei; floor(sum / 37) = 3,625,667,567,567,567 wei, which satisfies the `min: 1` guard. Since the brief marks this `"evidence": "panel"`, the recipe is `{kind: "panel", source: "https://ethereum-rpc.publicnode.com"}` as the checker requires, with the full computation described in `notes` and every choice the question left open (NFT item-type test, per-event sale counting, bid/listing price rules) stated under `definitions`.

Created [artifacts/answer.json](artifacts/answer.json) with the RPC reproduction procedure. Average: **3625667567567567 wei** across **37 sales**. Required checker returned `ok`.

Check passes: `ok`. Summary: scanned OrderFulfilled logs from Seaport 1.5/1.6 over the pinned block range (26019451–26026607, closing hash confirmed matched the pin), decoded the offer/consideration arrays by hand, and found 37 qualifying Shellmates sales in ETH/WETH totaling 134149700000000000 wei, averaging to **3625667567567567 wei**. Wrote `artifacts/answer.json` with a `panel`-kind recipe (required since the brief's `evidence` is `"panel"`) citing the RPC/methodology, and `check-answer.mjs` reports `ok`.

I wrote `artifacts/answer.json`, and the answer checker prints `ok`. **Answer: 3625667567567567 wei** (about 0.003626 ETH). That is 37 qualifying sales totalling 134149700000000000 wei, averaged and rounded down. - **How I got it:** I pulled every Seaport 1.5 and 1.6 `OrderFulfilled` event in blocks 26019451–26026607 from `ethereum-rpc.publicnode.com`. That was 12,231 events, and none of the requests were refused or cut short. I then decoded each one and applied the definitions in `oracle.json`. The provided `scan.mjs` can't decode Seaport's item lists, so I wrote my own decoder in `test/scratch/`. That folder isn't submitted. - **Checks:** that endpoint reports chain 1, and the closing block's hash matches the pinned one. A second operator, `rpc.flashbots.net`, gives the same hash. - **Recipe:** the brief marks this as a `panel` question, so the recipe is `{kind: "panel", source}`. The source names the endpoint, the event and the block range. - **Sales count depends on reading the definition literally:** in 6 transactions, one accepted bid produces two qualifying events: the buyer's order and the seller's matching order, which is net of fees. The definition counts every qualifying event, so I counted both. If other panel members count each of these as one sale, they'll get 31 sales and an average of **3736119354838709** wei. I put both figures in `notes`.

`artifacts/answer.json` is written and passes the plane's checker (`ok`). **Answer: 3625667567567567 wei** (≈0.0036257 ETH) average Shellmates sale price over blocks 26019451–26026607. How it was computed, all from public RPC: 1. Confirmed `eth_chainId = 0x1` and that block 26026607 hashes to the pinned `0x8a84f5aa…cdec2` on two independent operators (flashbots, publicnode). 2. `eth_getLogs` for the collection `0xaa83d0d7…75e0` over the whole window: 32 logs, all ERC-721 `Transfer`, in 20 blocks. Since every Seaport ERC-721 fill moves the token, only those 20 blocks can hold a qualifying sale — this keeps the scan small without narrowing the window. 3. `eth_getLogs` for `OrderFulfilled` (topic0 `0x9d9af8e3…`) on Seaport 1.5 and 1.6 in exactly those blocks: 73 events, decoded by hand into `SpentItem[] offer` / `ReceivedItem[] consideration`. 4. 37 events carried exactly one ERC-721 item of the collection and no other NFT; **all** of them were payable in ETH or WETH, so nothing touching the collection was dropped as a bundle, an ERC-1155 or a non-ETH payment. 17 listing fills (sum of all consideration, fees included), 20 bid fills (the WETH offer amount). 5. Sum 134149700000000000 wei ÷ 37, floored → 3625667567567567 (remainder 21). Cross-checks: the whole scan re-run with publicnode first in the rotation gave identical figures; and 31 distinct trades (37 less one half of each of 3 matched bid/listing pairs) plus 1 non-Seaport transfer tx = the 32 transfers seen in step 2. Two judgment calls are stated in `definitions`: the brief's `sale` is an *OrderFulfilled event*, so both halves of a matched pair count (counting economic trades instead would give 31 sales, average 3736119354838709 — the only open choice that moves the number); and the recipe is the `panel` kind because the brief sets `"evidence": "panel"` and no chain recipe in the catalogue can express a per-event struct-sum like this (noted explicitly in `notes`). Scratch scripts stayed under `/tmp`; nothing outside `artifacts/answer.json` was touched, and it is left untracked.

`artifacts/answer.json` is written, untracked, and `check-answer.mjs` prints `ok`. **Answer: 3625667567567567 wei** (≈0.003626 ETH) — the mean of 37 qualifying Seaport fills totalling 134149700000000000 wei. How it was computed, over exactly blocks 26019451–26026607: 1. **Pin confirmed on three operators** (flashbots, publicnode, mevblocker): `eth_chainId` = `0x1`, block 26026607 hash = `0x8a84f5aa…cdec2`. 2. **Narrowed the candidates**: `eth_getLogs` for `Transfer` on `0xaa83d0d7…75e0` over the window → 32 transfers in 20 blocks / 20 txs. Any qualifying Seaport fill must move the NFT, so those txs are a complete superset — this keeps the whole scan to 17 RPC calls with no truncation risk. 3. **Decoded Seaport**: `OrderFulfilled` logs from Seaport 1.5 and 1.6 in those blocks, restricted to those txs (45 events). 8 carried another collection's NFT; 17 were listing fills (price = sum of all ETH/WETH consideration, fees included) and 20 were bid fills (price = the ETH/WETH offer amount). All 37 came from Seaport 1.6. 4. **Verified the decoder**: every WETH-paid tx's decoded price equals the sum of that tx's WETH `Transfer` legs; the five ETH-paid txs whose outer `value` is 0 are ERC-4337 UserOperations sent to EntryPoint `0x5ff137d4…2789`, where the smart account pays internally. One judgement call the brief leaves open, stated under `definitions` and in `notes`: 6 token sales were matched orders emitting **two** qualifying `OrderFulfilled` events each (bid side and listing side). The brief defines a sale as the event, so both sides were counted — 31 distinct (tx, token id) sales produced 37 qualifying events. Counting each token sale once instead would yield 3736119354838709 wei; that alternative is recorded in the notes so a disagreeing panel member's figure is legible. The recipe is `{ kind: "panel", source }` because the brief sets `"evidence": "panel"` — the checker rejects any chain recipe for such a brief — with the source naming the endpoint, the topic, the contracts and the filter that reproduce the figure.

`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. The average sale price is 3625667567567567 wei. - **Sales counted:** 37 qualifying sales over blocks 26019451 to 26026607 (about 0.1341 ETH in total). - **Scan:** I fetched all 12,231 `OrderFulfilled` logs from both Seaport contracts and decoded them against the request's definitions. The scan ran from publicnode, and the closing block hash matched the pin. - **Not cross-checked:** I did not check the hash on a second operator's endpoint. The scan was one full pass, with no independent second scan of my own. - **Recipe kind:** The request says `"evidence": "panel"`, and the checker only accepts a `panel` recipe for that. So the recipe is a `panel` recipe whose `source` names the RPC endpoint, event topic, both Seaport contracts and the block range. The `log-sum` and `log-rank` kinds can't express this Seaport decoding. - **Script:** I used my own decoding script in `test/scratch/s.mjs`, not `scan.mjs`, because `scan.mjs` doesn't decode Seaport's item structs.

Because the brief sets `"evidence": "panel"`, the recipe is `{ kind: "panel", source: <RPC URL> }` as the checker requires; the exact filter (event signature/topic0, listing vs bid price rule, NFT-item exclusion, floor average, wei denomination) is spelled out under `definitions`, and the run procedure and endpoints are in `notes`.

Every fill that touched the collection was a single ERC-721 paid in ETH or WETH. - **Scan:** I fetched all 12,231 `OrderFulfilled` logs from both Seaport contracts over the pinned window from `ethereum-rpc.publicnode.com`. The chain id and closing block hash matched the pin on that endpoint. I did not check the hash on a second operator's endpoint. - **Decoding:** I used my own script, `test/scratch/s.mjs`, because `scan.mjs` doesn't decode Seaport events. - **Recipe kind:** the brief says `"evidence": "panel"`, so the reference only allows the `panel` recipe. I used it, with the RPC call and event topic as the `source` string. The deployer can't rerun a `panel` recipe on-chain; agreement among panel members is the evidence. - **Format quirk:** the checker requires the `window` keys in the order `toBlock`, `fromBlock`, `toBlockHash`. My first draft used a different order and failed, so I reordered it.
