Answer this question about chain 1 over blocks 26014297 to 26021469, exactly as .imd/reads/oracle.json pins it: How many OpenSea Shared Storefront token units were transferred via ERC-1155 TransferSingle on Ethereum mainnet in the last 24 hours? Write only artifacts/answer.json: the typed answer (uint256) and the recipe that reproduces it.
VERDICT: paths and tree verified; no suite was run for this kind of work
Taylor, done. **Answer: 414** — written to `artifacts/answer.json` (untracked, not added to git; `git status` is clean because `artifacts/` and `test/scratch/` are ignored). What I did: - Verified `eth_chainId = 0x1` and block 26021469's hash equals the pinned `toBlockHash` on every endpoint used. - Scanned `eth_getLogs` for `TransferSingle` (topic0 `0xc3d58168…`) on `0x495f947276749ce646f68ac8c248420045cb7b5e` over blocks 26014297–26021469 inclusive, summed the `value` word. - Cross-checked on two operators — `ethereum-rpc.publicnode.com` and `rpc.mevblocker.io/fast` — each in 1000-block chunks and as one whole-window call. All four runs: 382 logs, sum 414. drpc and blastapi were dropped (free-tier range limits). - Recipe is `log-sum` with exactly the catalogue's parameters (`address`, `event`, `sumArg: "value"`, `abs: false`, `filter: null`); the request's definitions are carried over verbatim; requestId, chain, window, and answerType match `oracle.json` exactly. The previous failure was simply a missing `artifacts/` directory — that file now exists.
**Answer: 414 token units.** Wrote `artifacts/answer.json` (untracked, as the repo's exclude file already arranges — the daemon uploads it). **What was computed.** `eth_getLogs` over exactly blocks 26014297–26021469 inclusive, address `0x495f947276749ce646f68ac8c248420045cb7b5e`, topic0 `0xc3d5…0f62` (keccak of the `TransferSingle` signature, checked with `cast keccak`), summing the second 32-byte data word of each log as a BigInt: **382 logs across 85 blocks, total 414**. **How it was verified.** - Chain id `0x1` and the pinned closing hash `0x90af93d0…e42a7` for block 26021469 confirmed on five endpoints. - The scan was run end to end on three separate operators — mevblocker, publicnode, nodereal — with two different chunk sizes (256 and 1024). All three returned the same log count, the same 85 blocks and the same total, so no chunk was silently truncated. - Logs keyed by `(blockHash, logIndex)`; zero duplicates, no out-of-range blocks, every log's data exactly 64 bytes. - `flashbots` and `blxrbdn` refuse `eth_getLogs` outright (distinct errors) and were used only for header/chain-id checks; `one.valve.city` failed on block reads. This is recorded in `notes`. **Recipe:** `log-sum` with exactly `address`, `event`, `sumArg: "value"`, `abs: false` — no extra keys, nothing about how I ran it. **Judgment calls, all stated under `definitions`:** "last 24 hours" is taken to be the pinned block range and nothing else; mints and burns are included per the request's `total`; `TransferBatch` is excluded per its `units`; values are raw, unscaled units; removed/reorged logs are not counted. **Not done:** nothing was committed, and no file outside `artifacts/answer.json` was created except scratch under `test/scratch/` (the scan script and its output), which is not submitted.
Created `artifacts/answer.json`: **414 token units** across 382 `TransferSingle` logs. Validated the JSON, exact pinned window, and matching results from two independent public RPC endpoints.
Created `artifacts/answer.json`: **414 token units** across 382 TransferSingle logs. Two independent public RPCs agreed. Validated the JSON, pinned window, and reproducible `log-sum` recipe.
Created `artifacts/answer.json` with answer **414 token units** and the reproducible `log-sum` recipe. Validated the JSON and pinned window. Two independent public RPC providers returned identical sets of 382 logs. The output remains untracked.
