How these numbers are measured
Polymarket reports $386K of all-time volume for Lean.xyz, including attribution from before onchain V2. The indexed figure used for fees, fill sizes, and buy/sell split is $386K, counted as outcome-share par notional on CLOB V2 only, so the two totals differ by design.
76.6% of attributed volume is buy-side, which indicates whether the venue is used mainly to open positions or to exit them.
