   The harness wraps the Dune Analytics API. A single saved query counts distinct

-  wallet addresses in the rolling 24-hour window, joined from solana.account_activity
-  for efficiency. All platforms including pump.fun use the same fee wallet attribution
-  approach against solana.account_activity (standard Dune tier). The harness re-executes
-  the query every hour, polls for completion, then updates the Prometheus gauge
-  solana_platform_unique_traders_24h per platform. Between executions it serves the
-  latest cached result every 15 minutes.

 faq:
   - q: "What does unique daily traders measure?"
-    a: "Unique daily traders counts the number of distinct wallet addresses (fee_payer in Solana transactions) that executed at least one trade through a platform in the rolling 24-hour window. It measures user breadth, not volume or frequency. A wallet that trades 1000 times counts as 1 unique trader."
+    a: "Unique daily traders counts the number of distinct fee-touching transactions (tx_id) in solana.account_activity where a platform fee wallet received SOL or USDC/WSOL in the rolling 24-hour window. It is a proxy for user breadth: the actual unique-wallet count is typically 3-10x lower since active traders execute multiple transactions per day. A wallet that trades 1000 times generates up to 1000 counted transactions."
   - q: "Why does pump.fun have so many more unique traders than GMGN?"
     a: "pump.fun is the default entry point for new Solana users and meme coin traders. Its bonding curve launch mechanic triggers massive multi-wallet bot activity as snipers race to buy newly created tokens. GMGN serves a more deliberate, power-trader segment that skews toward fewer unique wallets but larger position sizes."
   - q: "Is this apple-to-apple between pump.fun and the others?"
