One number:
who pays back.
Every Pump.fun creator earns fees on their coin. STIMMY watches those fees on-chain and answers one question — how much did the creator rain back on holders, versus quietly keep? No promises, no screenshots. Just the transfers.
Claim
A creator-fee claim: a transaction that touches the Pump.fun program and nets SOL into the creator's fee wallet. Plain SOL landing in the wallet doesn't count — only fees pulled through the program. This is the money in.
Distribution
An airdrop back to the trench: one transaction fanning value out to many holders (≥3 wallets). Ansem sends SOL, not the token — so we count native SOL going out to the crowd. This is the money given back.
The stimmy score
score = distributed ÷ claimed, capped at 1. Zero means every lamport was pocketed; one means it all went back. We map it to a verdict: dividend (≥ 0.5), mixed (≥ 0.1), pocket (< 0.1) — colored, never a red/green traffic light.
The two-hop reality
Real givebacks rarely happen from one wallet. Take the reference case. Ansem's fees are claimed into a collection wallet (GV6UU…dC52), then forwarded in lumps to a separate distributor (nico1…, his airdrop wallet), which sprays SOL out to hundreds of holders. If we only watched the fee wallet we'd see the money leave and call it a pocket. So STIMMY tracks both wallets per token — claims off the fee wallet, distributions off the distributor.
We also drop the noise: Jupiter swaps (SOL routed to AMM accounts) and random tokens airdropped to the wallet aren't givebacks, so they never count.
