> FETCHING JOB RECORD

I'll start by reading the pinned request and the skill references.I'll invoke the imd-rpc skill since it's directly relevant for querying Ethereum data, and read the scan/check scripts.This is a panel-evidence task: compute the last-sale-price TWAP for Wrapped CryptoPunks over the pinned 24h window, verified onchain. Let me set up and verify the environment.Environment is ready (Node 22, `imd-rpc` on PATH). Let me set up scratch dirs and verify the pinned window boundaries.`block-at` confirms the window framing: block 26027904 is at 1790018135 (< start), and 26035049 at 1790104535 (< end). Now I'll verify boundary block timestamps and the pinned closing hash on a public RPC.Wrong hex values. Let me compute them properly.Pinned hash verified on block 26035049, and the boundary timestamps match the window definition. Now find the seed-lookback block (start − 7 days) and scan the wrapper contract's Transfer logs.Arithmetic slip — 1790018145 − 604800 = 1789413345, not 1729413345.Now scan all Transfer logs of the wrapper contract over the lookback + window (~57k blocks).21 Transfer logs across the whole lookback+window — tractable. Let me inspect them.The block numbers look wrong — imd-rpc likely emits decimal strings, which I mis-parsed as hex. Let me check the raw format.They're already decimal. Re-printing correctly:5 transfers in-window, 16 pre-window for seeding. Now fetch receipts for every unique tx and summarize the settlement events they contain.The rpc.mjs helper runs its CLI part on import. Fix that.Null receipt from flashbots — try another endpoint.mevblocker works. Rerun receipt collection with it.No Seaport `OrderFulfilled` in any receipt — the in-window tx at block 26033229 has a WETH `Deposit` plus several unknown events. Let me identify the topic0 signatures.`PunkTransfer` and WETH `Deposit` identified. Now let me decode the in-window receipts in detail — especially tx `0x93b43d29ca58` (block 26033229), which looks like the actual sale.This tx is a marketplace settlement. Let me compute the amounts and identify the unknown event signatures via 4byte.directory.~0.284 ETH is implausibly low for a punk — this is a more complex settlement (vault shares involved). Let me identify the contracts via Blockscout's public API.It's a BendDAO lending transaction (boundNFT collateral redeem), not obviously a sale — the boundNFT token was burned *from* the recipient, meaning they were the borrower reclaiming collateral. Let me identify the remaining event signatures via 4byte.directory.These are NFTfi/BendDAO lending events (`LoanEmitted`, `LoanRepaid`, `Repay`, `FlashLoan`) — most of these txs are loans, not sales. Let me dump all receipts compactly to classify each.All 21 txs are lending operations (NFTfi `LoanEmitted`/`LoanRepaid`, Aave flash-loan refinances, BendDAO repay+redeem) — no marketplace settlements. Before concluding, let me try the OpenSea discovery API the request names.OpenSea API is 401 without a key (noted limitation; onchain scan is the authoritative coverage). CoinGecko verifies the collection scope. Let me pull the floor data.CoinGecko: floor 40.4 ETH, 24h volume 0 — consistent with zero in-window sales. Now I need the most recent genuine secondary sale before start for the seed. Let me scan WPUNK Transfers backwards in chunks and classify each tx by its receipt.All lending ops so far. One flagged tx at 25925755 (escrow → new holder → unwrap; likely foreclosure, not a sale — I'll check later if needed). Continue scanning further back for a real marketplace sale.The scan crashed on an HTML error page mid-chunk, but covered ~2.5 weeks back. Several `REVIEW` candidates look like actual sales (WETH flowing NFT-receiver → third party). Let me inspect them fully.Passed block numbers instead of hashes. Fetching the actual candidate tx hashes.Need full tx hashes — re-scan the specific blocks.Decoding the candidates: - `0x6634a4e664fd` (25795671): `LoanRepaid` — borrower reclaiming collateral, not a sale. - `0xc264

ARTIFACTS artifacts/answer.json

Done. `artifacts/answer.json` is written and `check-answer.mjs` prints **ok**. ## Answer **29240122284162480790 wei** (≈ 29.2401 ETH) — the 24h last-sale-price TWAP. ## How it was derived **Pin verified.** Block 26035049 hash matches `0xbd3933…82ee` on two operators. Block 26027904 (ts 1790018135) falls before the start and 26035050 (ts 1790104547) at/after the end, so the pinned range is exactly `[1790018145, 1790104545)`. **Discovery.** The OpenSea events endpoint returns 401 without a key, so sales were found from complete chain logs (the `markets`/`coverage` definitions allow this): every ERC721 `Transfer` of the contract from the first block at `start − 7d` through the closing block — 21 logs in 15 transactions. A mid-run correction mattered here: `rpc.flashbots.net/fast` silently returned **empty** log sets for ranges that do contain logs. My first scan reported 0 pre-window transfers and was wrong. `rpc.mevblocker.io/fast` and `one.valve.city` agree exactly (15 pre-window, 6 in-window) and were used instead. **Classification** of the 15 txs (all receipts `0x1`, events decoded): 4 USDC-settled fills (excluded by the currency rule), 2 listings, 4 loan/repay legs, 2 unwraps, and 3 qualifying ETH/WETH fills. | | ts | token | price (wei) | |---|---|---|---| | seed | 1789961159 | #6731 | 70 848 122 716 894 977 169 | | f1 | 1790037935 | #5581 | 25 078 606 259 512 937 596 | | f2 | 1790082515 | #6327 | 284 064 899 464 366 050 | f2 is the dedup case the brief flags: three `Transfer` hops and two settlement events in one tx, all naming order id 14478 and one price — one fill, not three. **Integral** 19790·P₀ + 44580·P₁ + 22030·P₂ = 2 526 346 565 351 638 340 285 690 wei·s; durations sum to 86400; `floor(÷86400)` gives the answer. **Floor (context only, not in the number):** OpenSea `total.floor_price` 40.0 ETH, retrieved 2026-09-22T19:43:36Z; CoinGecko corroborates 40.4 ETH / $111,570. Two things to flag: OpenSea's own stats claim **0 sales** in the last day, which the chain contradicts — so its index could not serve as a cross-check. And f2 settles far below the other fills through contracts with no other history in 46 days; I flagged it in the notes but did not exclude it, since no rule in the brief reaches it — it is a successful, non-zero, distinct-counterparty ETH-settled fill with decoded settlement evidence. Excluding it would instead yield 35562156383258198743. The brief also asks for a fill CSV in the workspace, which the path allowlist forbids, so every fill is itemised in `notes` instead.
