fix(207): switch pump.fun from fee wallet to dex_solana.trades - #1940
Merged
Conversation
After the 0% bonding-curve fee cut (2026-08-07), pump.fun fee wallets still
received micro-SOL on every tx (rent side-effects), inflating unique tx count
by ~60%. Switch to dex_solana.trades WHERE project IN ('pumpdotfun','pumpswap')
which indexes actual swap events. Validated: 6.0M vs 9.7M (Dune query 8318587).
Also updates bench YAML: title, metric label, methodology notes, disclaimer,
and FAQ entry explaining the data-source switch.

All providers now measure COUNT(DISTINCT tx_id) over 24h of real swap activity. Data source differs (fee wallet vs Spellbook) but the underlying event is the same.
