Trends (daily, 34d window)
Trade-size mix (Topaz, last 14d)
94.9% of this pair's Topaz volume is sub-$1k fills. Small, aggregator-routed flow is generally less sensitive to a fee change than size shopping for execution — so a book weighted to the top of this table has more fee headroom than its volume alone suggests.
| Trade size | Swaps | Volume | Share of volume | |

Fee change effectiveness (hourly)
Competitor-normalized before/after at the hour level. The change hour is excluded; "before" is the 24 closed hours prior, each "after" window the first 6/24/72/168 closed hours since (bounded by the next change). Verdict weighs Topaz fees/hr and volume share and competitor flow — a fee that lifts revenue but bleeds routing share is not "working". Topaz hourly data refreshes hourly (:05), so a change shows pending only until its first 6 post-change hours close; competitor flows ride the 6-hourly collect, so the normalized side can trail by up to ~6h.
no clear signal: fees/hr -17%, vol share +0%, competitor vol/hr n/a over first 72h

Fee change impact
On-chain fee changes on this pair's Topaz pool(s), with volume & fee generation before vs after each change. Each side spans all days until the adjacent change; rates are per active day (the two sides usually differ in length). Marked on the charts above. Values are raw module units (pips, ÷100 = bps; scaling is the raw uint64 K).
