The metric I designed was the same number twice

Description and use

The tool leverages maker addresses from CoinMarketCap’s DEX API to measure side concentration and detect a single wallet’s dominance, revealing hidden asymmetry when net flow appears balanced.

Problem

DEX flow tools reduce activity to a single net flow number (buy volume minus sell volume), which loses information and cannot distinguish a desk distributing to retail from a churn of traders.

Outcome

The tool shows that a single wallet can hold a large percentage of one side’s volume even when net flow is balanced, providing a clearer view of market concentration.

Workflow

• 1. Fetch swap data from /v1/dex/tokens/transactions for the desired token and pages.
• 2. Split swaps by side (buy/sell).
• 3. For each side, aggregate USD value per maker address.
• 4. Identify the maker with the largest share of the side’s total volume.
• 5. Report the largest share percentage for each side.
• 6. Compare with net flow to detect hidden asymmetry.

Evidence

The largest wallet’s share of its own side is the number. No model, no heuristic, no threshold I had to invent.

Three of the four CORS headers are sent. A successful keyless response carries access-control-allow-headers, access-control-allow-methods and a ten-minute access-control-max-age — and omits access-control-allow-origin.
