Answer this question about chain 56 over blocks 123188258 to 123196253, exactly as .imd/reads/oracle.json pins it: How much WBNB (Wrapped BNB, token 0xbb4cdb9cbd36b01bd1cbaebf2de08d9173bc095c) was transferred on BNB Smart Chain in the last 1 hours, in base units with 18 decimals? Sum value over every Transfer event of that contract over the pinned window. 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
`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. **Answer:** 91415144151040061413661 WBNB base units, about 91,415.14 WBNB. That is the sum of `value` over 229,212 Transfer events from 0xbb4cdb9c…c095c, spread across 7,995 blocks, for blocks 123188258 to 123196253 inclusive. - **Pin:** every scan confirmed chain 56 and the pinned closing hash `0x0beac124…fe43d`. - **Cross-check:** complete scans on three different operators (`rpc.swiftnodes.io`, `bsc.rpc.sentio.xyz` and `bsc-rpc.publicnode.com`) gave the same count and sum. - **Endpoints that failed:** `public.1rpc.io/bnb` hit its usage limit, and `api.zan.top` returned 429s. - **Recipe:** `log-sum` on that contract, event `Transfer`, summing `wad`, with `abs` false. - **Definitions:** the file states the inclusive window, that every Transfer log counts once with no filtering of mints, burns or zero values, and that Deposit and Withdrawal events are not counted. - **Window key order:** the check requires the `window` keys in the brief's order (`toBlock`, `fromBlock`, `toBlockHash`), so I reordered them to match. I ran more full scans than the brief asked for, since the first two endpoints failed.
