Trades are attributed to the wallet that really received or sent the token, so Coinbase smart wallets and aggregator routes count as the real trader. Wallet types from on-chain data: trader, fresh_wallet (< 10 tx, possible insider), smart_account, high_frequency_bot, contract. Base, Ethereum, BSC, Arbitrum, Polygon, Avalanche, Optimism.
