  "notes": "Computed from public JSON-RPC data using the supplied scan.mjs keccak256 and scanLogs logic, exported in temporary scratch scaffolding. Verified chain 8453 and the pinned closing hash on https://base.rpc.sentio.xyz, https://mainnet.base.org, https://base-public.nodies.app, https://base-mainnet.public.blastapi.io and https://base-rpc.publicnode.com. Scanned Initialize(bytes32,address,address,uint24,int24,address,uint160,int24) on Sentio in inclusive, non-overlapping 10000-block chunks from 25352561 to 51605560, filtering indexed pool id for all 1241 pools that emitted Swap in the pinned window, then selecting pools with USDC as currency0 or currency1. Found 352 initialization events representing 352 USDC pools with swaps in the window. Pools without swaps have zero volume and cannot displace the positive-volume leaders. Scanned Swap(bytes32,address,int128,int128,uint160,uint128,int24,uint24) on mainnet.base.org in 600-block chunks over exactly the request window. Joined indexed pool id to Initialize currencies, decoded data word 0 or 1 as signed int128, and summed absolute values. Of 24122 swaps, 10146 matched USDC pools, covering 352 active pools. Ranked raw totals in answer order: 492277653930, 202127395679, 78577471613, 75872341843, 71369918666. USDC decimals() at the closing block returned 6. Earlier unrestricted amount0 scan with the supplied CLI was diagnostic only, not the USDC ranking.
