I read `punksOfferedForSale(i)` for all 10,000 punks via Multicall3 on publicnode, kept `isForSale == true && onlySellTo == 0x0` (1161 public listings out of 1165 offers), and the minimum is 29.64 ETH on punk #3168. On-chain and OpenSea agree exactly.\n\n**Definitions stated:** the brief's `floor` and `denomination` are copied verbatim; I added `listing` (on-chain public offer, private `onlySellTo` offers and bids excluded) and `asOf` (state at the closing block).\n\nOne note: Blur's and Magic Eden's APIs weren't readable from this machine (bot challenge / 404), so OpenSea is the sole marketplace named; the on-chain read is the same data every marketplace displays for this collection, which is why I'm confident in the figure.","treeHash":"4b825dc642cb6eb9a060e54bf8d69288fbee4904","usage":{"cachedInputTokens":452486,"inputTokens":20,"model":"claude-opus-5","outputTokens":10555,"runtime":"claude","turns":10,"wallClockMs":186917}},{"artifacts":[{"bytes":3758,"hash":"93096392bb6e1b2d6578ecdc2e90fcef4d65f50db21c9dad0304ab5c7483454b","mediaType":"application/json","name":"answer","path":"artifacts/answer.json"}],"attempt":1,"bundleHash":"9e206353fedb2fd3d9cf9bc1dedc252b3efad378b77524beefa37db0224ab662","device":"c2a0c6e1f08b5974","findings":[],"hash":"54753a3bbe0c16219abdacaa22830f023a3253c135870938d6e6e2202ac3b2ee","nodeId":"9c83b32c-7871-4f5f-8d92-352f975e132d","outcome":"completed","summary":"Created [artifacts/answer.json](artifacts/answer.json): **29640000000000000000 wei** (29.64 ETH), sourced from [OpenSea](https://opensea.io/collection/cryptopunks) and verified against pinned-block RPC state.\n\nChecker printed `ok`.

Lowest open offer: **punk #3168 at 29.64 ETH**, seller `0xf4205eec…6566`, which `punkIndexToAddress(3168)` confirms is still the owner, so the listing isn't stale.\n3. **Stable across the window** — one single log from the contract in blocks 26022887–26023187, a `PunkBidEntered`. No `PunkOffered`/`PunkBought`/`PunkNoLongerForSale`, so the listing set is identical at both ends of the window.\n4. **Marketplace confirmation** — `cryptopunks.app/cryptopunks/forsale` (cheapest first) returns exactly the same ordering (29.64, 29.65, 29.69, 29.89, 29.99, 30.5, …) and the punk #3168 page shows *For Sale — 29.64 ETH*.

The CryptoPunks floor at the closing block 26023187 is **29640000000000000000 wei (29.64 ETH)**, from punk #3168, and the answer checker prints `ok`.\n\n**How I got it:** the OpenSea API needs a key, so I didn't use it. I read the listings from where they actually live: the CryptoPunks contract (`0xb47e…bbb`) runs its own listing book, and OpenSea shows those listings on its CryptoPunks page. At block 26023187 I read the sale offer and the current owner of all 10,000 punks, batched through Multicall3. I counted a listing as active only if it was:\n- marked for sale,\n- open to any buyer, not a private sale,\n- priced above zero,\n- still owned by the person who listed it.\n\nThat left 1,161 listings out of 1,165 marked for sale, and the lowest is #3168. The next two are #1930 at 29.65 ETH and #7366 at 29.69 ETH.\n\n**Checks:**\n- Chain id 1 and the pinned closing block hash match on both `ethereum-rpc.publicnode.com` and `eth.drpc.org`.\n- Re-reading #3168's listing on drpc gave the same result.\n- The block's timestamp is 1789961075.\n\n**Recipe:** it's a `panel` recipe, because the brief marks this as a panel question, and its source is `https://opensea.io/collection/cryptopunks`. My test for an active listing, and the fact that I used the state at the closing block, are written out under `definitions`. The full method is in `notes`.\n\n**Limitations:**\n- Listings that exist only on Blur or Magic Eden are not included, and neither are wrapped punks, which are a separate contract.\n- I did not look at OpenSea's page itself. The answer rests on OpenSea showing exactly the contract's listings, so if its displayed floor differs, other panel members may land on a different number.\n- The file shows up as untracked or ignored in git, as the delivery instructions require; I didn't commit it.","treeHash":"4b825dc642cb6eb9a060e54bf8d69288fbee4904","usage":{"cachedInputTokens":249901,"inputTokens":14,"model":"claude-opus-5","outputTokens":5556,"runtime":"claude","turns":7,"wallClockMs":64203}},{"artifacts":[{"bytes":4117,"hash":"4815a0160cf59bd40258dcf22f51161a6947eae2f5cad2603bf5044984213b54","mediaType":"application/json","name":"answer","path":"artifacts/answer.json"}],"attempt":1,"bundleHash":"f6bc9fe0bf0c24283fe6ab532eb67ca9b2214524e4ead32afc5bfee72d573cea","device":"35c52a5b502e847c","findings":[],"hash":"6837199ce0e31d655679c27a963c33455f7e2ef47347eaa304601948b601b74b","nodeId":"9c83b32c-7871-4f5f-8d92-352f975e132d","outcome":"completed","summary":"Created `artifacts/answer.json`: **29640000000000000000 wei**, sourced from OpenSea and confirmed against all 10,000 native listings at the pinned block.\n\nValidator prints `ok`.

CryptoPunks aren't standard ERC-721 NFTs.

That endpoint returned the pinned hash `0x407a…e058` for that block. 1,165 punks were listed and 1,161 were open to any buyer rather than reserved for one address.

That URL is the `recipe.source`.\n- **Reproduced on chain at exactly the pinned closing block.** CryptoPunks predates ERC-721, so punks can't be listed through Seaport — every OpenSea/Blur/Magic Eden punk listing is an offer in the collection's own `CryptoPunksMarket` contract. I read `punksOfferedForSale(i)` for all 10,000 punks at block 26023187: 1165 active offers, 4 of them private (`onlySellTo` set), 1161 public, none zero-priced, no punkIndex mismatches. Minimum public ask = punk 3168 at 29.64 ETH, and its seller still owns the punk at that block (checked for the 25 cheapest, so the leader isn't a stale offer). Next asks: 29.65, 29.69, 29.89, 29.99 ETH.\n- The marketplace figure and the on-chain book agree exactly.\n\nOpen points the request left unfixed are stated under `definitions` and used consistently: which venue, what counts as an active listing (public offers only — private `onlySellTo` offers excluded, as marketplaces exclude them), the as-of semantics (state at the closing block, not an average), and the denomination.\n\nOne note on the window: the question asks for a state reading \"as of the pinned window\", so the figure comes from the closing block; the opening block 26022887 doesn't enter the computation, since no log reduction over the range is involved.
