Swap topic0 is 0x40e9cecb9f5f1f1c5b9c97dec2917b7ee92e57ba5563708daca94dd84ad7112f. Decode the first two nonindexed ABI words as signed amount0 and amount1. Historical Initialize scanning was limited by public RPC quotas, so currencies were also recovered using PositionManager 0x7c5f5a4bbd8fd63184577525326123b519429bdc poolKeys(bytes25) calls at the closing block, transaction input, and debug_traceTransaction callTracer data from https://base.drpc.org. Reconstructed ABI-encoded PoolKeys were checked by keccak256 against the full pool ID. Partial Initialize logs came from https://mainnet.base.org. Currency identification ultimately covered all 999 active pool IDs; no pool was left unclassified. The catalogue recipe reproduces the same ranking without these lookup optimizations: scan Initialize logs from initializedSince through toBlock (topic0 0xdd466e674ea557f56295e2d0218a125ea4b4f0f6f3307b95f85e6110838d6438; indexed id, currency0, currency1), retain native-ETH pools, join to window Swap logs, sum absolute ETH amounts, then sort and take five.
