abstract: |
The harness fetches the top 10 tokens by market cap from pump.fun every 5
minutes, then pulls the last 200 trades per token from Mobula's
`/api/2/token/trades-enriched` endpoint (`chainId=solana:solana`). Each trade
carries a `platform` tag (fomo, pump-fun, photon, axiom, …) and three fee
fields: `platformFeesUSD`, `gasFeesUSD`, `mevFeesUSD`. We group by platform,
compute the average total fee (sum of all three) as a percent of `amountUSD`,
and emit `memecoin_platform_fee_pct`. The leaderboard sorts by the median of
that gauge over 24 hours.
token/trades-enriched endpoint (chainId=solana:solana). Each trade carries a
platform tag (fomo, pump-fun, photon, axiom, trojan, gmgn...) and three fee
fields: platformFeesUSD, gasFeesUSD, mevFeesUSD. We group by platform, compute
the average total fee as a percent of amountUSD, and emit
memecoin_platform_fee_pct. The leaderboard sorts by the median over 24 hours.

formula: avg(memecoin_platform_fee_pct) by (platform)
methodology:
- "Tokens: top 10 by market cap from pump.fun, refreshed every 5 minutes."
- "Trades: last 200 trades per token from Mobula token/trades-enriched (chainId=solana:solana)."
- "Cost: totalFeesUSD / amountUSD * 100, covering platform fee plus gas plus MEV."
- "Grouping: trades are split by the platform field returned by Mobula (fomo, pump-fun, photon, axiom, trojan, gmgn, maestro, phantom)."
- "Cadence: full sweep every 5 minutes; each poll covers the 200 most recent trades per token."
- "Aggregation: headline is the average of memecoin_platform_fee_pct across all tracked tokens over 24 hours."

- "{{worst_name}} has the highest average fee at {{worst_p50}} (p50, 24h). Trading bots charge a fixed tip on top of DEX fees, which dominates at small trade sizes."

faq:
- q: "Is Fomo cheaper than pump.fun?"
a: "{{best_name}} currently leads at {{best_p50}} (p50, 24h). The live leaderboard refreshes every 5 minutes from Mobula trade data."
- q: "What fees do memecoin trading platforms charge?"
a: "Native clients (pump.fun) charge a protocol fee on each swap. Aggregator frontends (Photon, Axiom) add a referral tip on top. Trading bots (Trojan, Maestro, GMGN) charge a fixed percentage per trade. Gas is a separate Solana transaction fee. This benchmark combines all three into a single all-in percent."
- q: "Does MEV affect Solana memecoin trading?"
a: "Minimally at this scale. Solana's parallel execution and fast finality reduce MEV extraction compared to EVM chains. The mevFeesUSD field in Mobula's data is near zero for most trades on these tokens."
