Dashboards Caught Double-Counting Polymarket Trades

[encrypted]

DefiLlama, Allium, Blockworks, and several Dune dashboards all repeated the same mistake: combining both sets of Polymarket trade events and counting them as separate volume. The error inflated both notional and cashflow metrics. Paradigm says the root issue is Polymarket’s unusually complex transaction structure, which standard explorers cannot easily interpret.
