Answer this question about chain 8453 over blocks 51601956 to 51605556, exactly as .imd/reads/oracle.json pins it: How much USDC (USD Coin, token 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913) 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
Now let me read the scripts to know the exact invocation.The task is clear: sum `value` over every `Transfer` event of USDC on Base over the pinned window. Running the scan script now.BlastAPI rate-limited too. Rotating to the next endpoints.Pin confirmed on a second operator. Writing the answer file.Done. `check-answer.mjs` prints `ok`. **Answer:** `6597588693556128` base units (~6.6B USDC) transferred over blocks 51601956–51605556. How it was computed: - `scan.mjs` against `base-rpc.publicnode.com`, `eth_getLogs` for `Transfer(address,address,uint256)` on `0x833589fcd6edb6e08f4c7c32d4f71b54bda02913`, summing data word 0 — 418,036 logs across all 3,601 blocks. - Pinned closing hash `0x2b37…c4af` confirmed by the scan and cross-checked via `eth_getBlockByNumber` on `mainnet.base.org` (second operator). - `base-public.nodies.app` (50-block cap + persistent 429s) and `base-mainnet.public.blastapi.io` (429) refused first; noted in `notes`. - Recipe: `log-sum` on the same contract/event/`value`, `abs: false`, reproducing the figure from public RPC alone.
