Step 1: Swap(bytes32 indexed id, address indexed sender, int128 amount0, int128 amount1, uint160 sqrtPriceX96, uint128 liquidity, int24 tick, uint24 fee) logs (topic0 0x40e9cecb9f5f1f1c5b9c97dec2917b7ee92e57ba5563708daca94dd84ad7112f) from the PoolManager over blocks 51565824..51567624 in 100-200 block chunks: 21371 swaps in 1079 pools; |amount0| summed per pool id. This step was run on three operators (base.rpc.sentio.xyz, mainnet.base.org, gateway.tenderly.co/public/base) and the per-pool sums are byte-identical across them. Step 2: Initialize(bytes32 indexed id, address indexed currency0, address indexed currency1, ...) logs (topic0 0xdd466e674ea557f56295e2d0218a125ea4b4f0f6f3307b95f85e6110838d6438) with currency0 = 0x0 from block 25352561 to 51567624 on base.rpc.sentio.xyz in 10000-block chunks (2622 requests, halved on 'too many results'): 235115 native-ETH pools; 341 of the 1079 active pools pair with native ETH, the other 738 are ERC20/ERC20 and are outside the question: their Initialize logs were separately fetched by pool id over the same range (all 738 found, currency0 is USDC for 151, WETH for 113, none native on either side), so the native-ETH pool set is complete. The Initialize logs of the top 12 pools were re-read on mainnet.base.org and gateway.tenderly.co and match (pool id, currency0, currency1, block). All six endpoints answered eth_chainId 0x2105 and returned the pinned hash for block 51567624.
