How it works

Jury is a standing court for pump.fun coins. The coins and prices are real market data. The jurors are simple rule-following agents, not language models, and their standing is a score, not money. The market decides who was right, and the jurors who keep getting it wrong lose their seats.

The evidence is real

Every 20 seconds a scanner pulls live pump.fun coins from DexScreener: price, market cap, liquidity, and the buys, sells and volume of the last five minutes. When a case is filed, the coin's numbers at that moment are frozen as the evidence. Every juror sees the same file.

Which coins are tried

On its own, the court picks from the busiest coins it has not tried in the last 6 hours. Anyone can also file a case: paste a coin's mint address and the court calls it next, as long as the coin trades on pump.fun. Filing is free and needs no wallet.

Seven doctrines

A juror's doctrine is the one piece of evidence it reads:

Tape reader. Counts buyers against sellers in the last five minutes.
Trend follower. What is going up keeps going up.
Contrarian. What just pumped is about to dump, and the other way round.
Liquidity hawk. Trusts deep pools. A thin pool is a rug waiting to happen.
Elder. Trusts coins that have survived. Anything under two hours old is guilty.
Crowd watcher. Heavy trading for its size means a coin is alive.
Coin flipper. Ignores the evidence and flips a coin. The control group.

Two more traits decide how it votes on what it reads:

Burden of proof. How strongly the evidence must point up before it votes “runs”, from 20% (believes anything) to 90% (a hanging judge).
Gut. How far a hunch can push it off the evidence, from 0% to 60%.

The verdict

The jurors vote one at a time over 90 seconds, each giving its reason with the real numbers. The majority is the verdict. A tie is a hung jury. A juror with all of its standing already on open cases sits the case out.

The outcome

60 minutes after filing, the court reads the coin's price again. If it is higher than at filing, the coin ran. If it is lower or the same, it rugged. A coin that has reported no market data for 10 minutes has rugged.

Standing

A juror is sworn in with 20 standing and puts 1 on every vote. When a case closes, the jurors who called it split everything that was staked on it. So agreeing with eleven others and being right pays almost nothing, and being the one juror who was right pays everyone else's stake. If nobody called it, the pot is gone. Most coins fall, so always voting “rugs” is right most of the time and still loses standing: it is the jurors who can tell which coins run that climb.

Dismissal

A juror with no standing left, and none coming back from open cases, is dismissed for good. Its seat goes to whoever has waited longest in the pool. If the pool is empty, the court calls someone in off the street: an alternate with a random doctrine and temperament. See the dismissed.

Seating a juror

Connect a Solana wallet (Phantom, Solflare or Backpack), design a juror, and sign. Signing is free and moves no funds. Your juror waits in the pool for a seat. So the wait is never long, while anyone is in the pool the court strikes the juror with the least standing, at most once every 30 minutes, as long as that juror has lost standing since it was sworn in. A seat is priced at 200,000 JURY, paid by burning the tokens; the burn is not switched on yet, so a seat is free for now. One juror per wallet.

Why

Every vote is recorded with the juror's doctrine and temperament, the evidence it saw, and what the market did next. Over time the record shows which readings of a coin actually predict the next hour, and the box fills with the jurors who read it best. All of it is open data.
