Ethereum Wallet Profiling Data: Raw Uniswap Transaction Logs and NBD-Processed Behavioral Features

Dataset Description 1.1 Source and Collection of raw data All swap events emitted by the Uniswap v3 ETH/USDC 0.05% fee-tier pool(0x88e6A0c2dDD26FEEb64F039a2c41296FcB3f5640) on Ethereum mainnet werecollected between blocks 24,384,021 and 24,469,780 (04–16 February 2026,11.98 days) using a custom JSON-RPC collector that processes blockssequentially and caches transaction receipts per block to minimise RPCoverhead. Each record corresponds to one swap event and contains fifteen fields:block number, log index, timestamp, three address fields, trade side,base and quote quantities, execution price, price impact, gas used, gasprice, transaction fee, and transaction hash. The structure intentionallymirrors proprietary trader logs used in CEX microstructure research,enabling direct application of order-flow analysis methods todecentralised venue data. Address decomposition. Three distinct roles are captured per swap:tx_sender (the account that signed the transaction), swap_sender(the msg.sender of the pool's swap() call, typically a router), andrecipient (the address credited with output tokens). In direct swapsall three coincide; in router-mediated swaps they diverge. Thisdecomposition is the basis for the forensic separation of MEV bots fromretail users and routing contracts in Section 4. Derived fields. Execution price is decoded from the sqrtPriceX96value in each Swap event log. Price impact (impact_pct) is computedsequentially within each block—each trade's impact is measured againstthe execution price of the immediately preceding swap in the sameblock—consistent with the sandwich attack literature. Thegas_price_gwei field records effectiveGasPrice from the transactionreceipt; under EIP-1559 this is the priority tip, not base fee plus tip.This is confirmed empirically: 61.3% of transactions record sub-1-Gweivalues, inconsistent with mainnet base fees during the period (1–20Gwei). Gas fields are therefore treated as signals of inclusion urgencyrather than absolute cost. 1.2 Sample Overview Thirty records with sub-wei ETH quantities and zero USDC volume wereexcluded as contract dust artefacts. The cleaned sample is summarisedbelow.
