Answer this question about chain 8453 over blocks 51601957 to 51605557, exactly as .imd/reads/oracle.json pins it: How much USDbC (USD Base Coin, token 0xd9aaec86b65d86f6a7b5b1b0c42ffa531710b6ca) was transferred on Base in the last 2 hours, in base units with 6 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
Created `artifacts/answer.json` with **53596141803 base units**, summed across 1,762 Transfer events in the exact pinned window. Included the reproducible recipe and definitions. The required validator printed `ok`.
Created `artifacts/answer.json` with the reproducible recipe. Total: **53,596,141,803 base units**, summed across 1,762 Transfer events over the exact pinned window. Validation printed `ok`.
`check-answer.mjs` prints `ok`. The task is complete: `artifacts/answer.json` reports a total of **53,596,141,803** base units (6 decimals) of USDbC transferred via `Transfer` events over blocks 51601957–51605557 on Base, using a `log-sum` recipe summing the `value` argument across all 1,762 Transfer logs — pin-verified against the closing block hash on two independent RPC operators (base-public.nodies.app and mainnet.base.org).
**53596141803** USDbC base units (53,596.141803 USDbC) transferred over blocks 51601957–51605557, from 1762 Transfer logs; closing hash confirmed on a second endpoint. `check-answer.mjs` prints `ok`.
