Methodology
Wallets are classified as algorithmic if they placed more than 50 trades on their peak day or more than 1,000 trades over their lifetime. This rule follows Paper 1. Algorithmic share is the fraction of weekly counterparty events attributable to algorithmic wallets. Each on-chain match has a maker (limit order) and a taker (market order); both are counted as separate participations to capture both sides honestly. The remainder is split among active retail (10-1,000 trades), sophisticated (large volume with diversified HHI), casual (2-9 trades), and one-shot (single trade) classes.
