The total is **11342808464581567686222482** raw SAND units, about 11.34 million SAND. I wrote it to `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. - **How it was computed:** I ran `scan.mjs` against `https://ethereum-rpc.publicnode.com` over exactly blocks 26043139 to 26044928, both ends included. The endpoint reported chain id 1 and the same closing block hash that `oracle.json` pins. It found 181 Transfer logs from the SAND contract (`0x3845badade8e6dff049820680d1f14bd3903a5d0`) in 148 blocks, and the answer is the sum of their `value` fields. Mints and burns are included, as the request defines. - **Recipe:** `log-sum` on that contract, using the request's `Transfer` event, summing `value`, with `abs: false`. - **Definitions:** copied word for word from the request. This was a single scan from one endpoint. I didn't check the closing hash on a second provider. The checker's one complaint was the order of the keys in `window`: they have to be in the same order as `oracle.json`, so I reordered them. `artifacts/answer.json` is left untracked, as instructed.

SAND transferred over blocks 26043139 to 26044928 (both inclusive) was **11342808464581567686222482** base units, from 181 Transfer logs. `check-answer.mjs` prints `ok` for `artifacts/answer.json`. - **How I computed it:** I ran the scan script once over the pinned range on `https://ethereum-rpc.publicnode.com`. That is the only endpoint I used, so I did not cross-check the closing block hash on a second operator. The closing block hash matched the pin. - **Definitions:** The sum covers every Transfer log from the SAND contract (`0x3845badade8e6dff049820680d1f14bd3903a5d0`), mints and burns included, in raw 18-decimal units with no scaling. These come from the request and are copied into `definitions`. - **Recipe:** It is a `log-sum` over `Transfer.value` for that contract, with `abs` false. `notes` records the scan command I ran.
`artifacts/answer.json` is written and `check-answer.mjs` prints `ok` for it. The answer is **11342808464581567686222482** raw SAND units (18 decimals). That is the sum of `Transfer.value` over 181 Transfer logs from the SAND contract, `0x3845badade8e6dff049820680d1f14bd3903a5d0`. The range is blocks 26043139 to 26044928 inclusive, and the scan confirmed the pinned closing block hash. I ran one scan with `scan.mjs`, from one endpoint (`https://ethereum-rpc.publicnode.com`). I did not cross-check the closing hash on a second operator's endpoint, and the notes say so. The recipe is `log-sum` on that contract and event, summing `value`. It names the same contract, event and range as the scan. The first check failed because the checker wants the `window` keys in the brief's order (`toBlock`, `fromBlock`, `toBlockHash`). I reordered them.

The recipe is a `log-sum` of `Transfer.value` on the SAND contract. I ran one scan from `https://ethereum-rpc.publicnode.com`, and the closing block hash matched the pin. I did not cross-check the hash on a second endpoint. Mints and burns are included, and both block bounds are inclusive, as the request defines. The notes name the scan command and the endpoint. `check-answer.mjs` rejected the first draft because the `window` keys were in a different order from `oracle.json`. I replaced `window` with the object copied from the brief.
I wrote `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. **Answer:** `11342808464581567686222482` base units of SAND, which is about 11,342,808.46 SAND. - **How I got it:** I ran the provided scan script against `https://ethereum-rpc.publicnode.com` for blocks 26043139–26044928, counting both ends. It added up `Transfer.value` from 181 SAND Transfer logs at `0x3845badade8e6dff049820680d1f14bd3903a5d0`, spread over 148 blocks. The whole range came back in one request, so the result wasn't cut short. - **Block check:** the pinned closing-block hash matched on that endpoint and on a second provider, `https://eth.drpc.org`. - **Recipe:** `log-sum` over that contract and the pinned `Transfer` event, summing `value` with `abs: false` and no filter, so mints and burns are counted. - **Definitions:** I copied the requester's definitions unchanged; none were left open. The first run of `check-answer.mjs` rejected the file because the `window` keys weren't in the same order as in `oracle.json`. I reordered them and it now passes. The file is not committed, as the task asks. `git status` doesn't list it, so the path seems to be git-ignored.

The SAND transferred over blocks 26043139 to 26044928 (both bounds inclusive) is **11342808464581567686222482** base units, which is roughly 11.34 million SAND. - **How I computed it:** I ran `scan.mjs` once against `https://ethereum-rpc.publicnode.com`, filtered to the SAND contract (`0x3845badade8e6dff049820680d1f14bd3903a5d0`) and its `Transfer` event, summing the value field. The closing block hash matched the pin. The scan found 181 logs. - **Recipe:** it is a `log-sum` recipe on that contract and event, summing `value`. The definitions copy the request's own: mints and burns are included and there is no decimal scaling. - **Not done:** I did not check the closing hash on a second endpoint from a different operator. The reference suggests this as a cheap extra check, and the answer rests on the one scan. - **Only failure:** the first draft failed the check because `window` had its keys in a different order from the request. Reordering them fixed it.
`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. **Answer:** 11342808464581567686222482 SAND base units (18 decimals) transferred over blocks 26043139 to 26044928, both bounds inclusive. - **How it was computed:** I ran `scan.mjs` against `https://ethereum-rpc.publicnode.com` with `--sum data:0` on the SAND Transfer event. The script confirmed the closing block hash matched the pin, and the scan found 181 Transfer logs, mints and burns included. - **Recipe:** it is a `log-sum` over the SAND contract `0x3845badade8e6dff049820680d1f14bd3903a5d0`, summing `value` on that Transfer event. - **Cross-check skipped:** I did not check the closing hash on a second endpoint from a different operator, which the reference suggests doing cheaply.
`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The answer is **11342808464581567686222482** raw SAND units (18 decimals, no scaling). That is the sum of `Transfer.value` over 181 Transfer logs from `0x3845badade8e6dff049820680d1f14bd3903a5d0`, blocks 26043139 to 26044928 inclusive. Mints and burns are included. I ran one full scan with `scan.mjs` against `https://ethereum-rpc.publicnode.com`, and it confirmed the pinned closing hash. I did not cross-check the hash on a second operator's endpoint, so the notes name publicnode as the only endpoint used. The recipe is a `log-sum` over the same contract and event, summing `value`, with `abs` false. The `definitions` block restates the request's own definitions.
I wrote `artifacts/answer.json` with an answer of 11342808464581567686222482 SAND base units. `check-answer.mjs` prints `ok` for it. - **Scan:** I ran `scan.mjs` over blocks 26043139 to 26044928 on `https://ethereum-rpc.publicnode.com`. It matched the pinned closing block hash and found 181 `Transfer` logs from the SAND contract `0x3845badade8e6dff049820680d1f14bd3903a5d0`. - **Recipe:** The recipe is a `log-sum` over `Transfer.value` for that contract. The request left nothing open, so `definitions` just repeats its own definitions. That includes mints and burns, inclusive bounds and raw 18-decimal units. - **Cross-check:** I did not check the closing hash on a second endpoint. It was one full scan from one operator, as the reference says is enough.
`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. The answer is **11342808464581567686222482** SAND base units, summed over 181 SAND `Transfer` logs (mints and burns included) across blocks 26043139 to 26044928, both inclusive. I ran `scan.mjs` once against `https://ethereum-rpc.publicnode.com`, and the closing block hash matched the pinned one. I did not cross-check the hash on a second endpoint. The recipe is a `log-sum` over the SAND contract, `sumArg` `value`, `abs` false. The scan command is in `notes`. The first draft failed the checker because the `window` keys were in the wrong order. I reordered them and it passed.
I wrote `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. SAND transferred over blocks 26043139 to 26044928 (both bounds inclusive) comes to **11342808464581567686222482** base units, with 18 decimals and no scaling. - **Scan:** I ran `scan.mjs` once against `https://ethereum-rpc.publicnode.com`, filtered to the SAND contract's `Transfer` event and summing the value field. The scan confirmed the pinned closing block hash, matched 181 logs and needed no range splitting. - **Second endpoint:** I did not check the closing hash on a second operator's endpoint. The brief only calls that check cheap and useful. - **Recipe:** It is a `log-sum` over the SAND contract's `Transfer` event, summing `value`, and it reproduces the figure from public RPC data alone. - **Scope:** Mints and burns are included, as the brief's definition says. I wrote only `artifacts/answer.json`.
