Rules Version 1 · 2026-10-16
Eight rules. One config.
Everything the engine does comes from the rules below. Each one says what it is, why it’s there, and what it looks like with real numbers.
The vault pays winners
The vault is one public SOL wallet the team funds. It pays every winning short, and it never pays more than it holds. Its balance is on the board and on Solscan.
- Why
- Somebody has to be on the other side of a short. Here that’s the vault, and it only spends SOL that’s already in it.
- Example
- The vault holds 20 SOL. You close a 1 SOL short after a 30% drop. The vault pays 0.3 SOL, you get 1.3 SOL, and the vault keeps 19.7.
Room to short
All open stakes added together can’t be more than the vault balance.
- Why
- At 1x, the most any short can win equals its stake. Keep total stakes under the vault balance and every winner can be paid, even if $GME goes to zero.
- Example
- The vault holds 20 SOL and 18 SOL is already shorted, so there’s room for 2 SOL. A 2.5 SOL short is refused until the vault is topped up or someone closes.
- Worth knowing
- Room grows when the vault is topped up, when shorts close, and from borrow fees.
Holding a short costs a little
You pay 1% of your stake per day while the short is open. It goes into the vault.
- Why
- Real shorts pay to borrow. This keeps idle shorts from sitting on the vault’s room for free, and it tops the vault up.
- Example
- A 1 SOL short held for 3 days pays 0.03 SOL. It comes off what you get back when you close.
Liquidation at +100%
When the live price reaches +100% from your entry, your short is liquidated. Your whole stake buys $GME, and those coins get locked. The engine then checks every other short again, and repeats until nothing else trips.
- Why
- At 1x, a +100% move means you’ve lost your whole stake. Using the live price keeps cascades instant, which is the squeeze.
- Example
- You short at a $50k market cap. Your line is $100k. A buyer pushes it to $100k, your 1 SOL buys $GME, and the price jumps again, maybe into the next line.
- Worth knowing
- Wicks count. A two-second spike to your line liquidates you, even if the price drops right after.
Closes use the average price
When you close, your result uses the average pool price over the last 5 minutes.
- Why
- Without it, someone could dump the coin for one candle and close a short at that low. The average makes that cost more than it pays.
- Example
- The price drops 40% for one minute and comes straight back. The 5-minute average only moved about 8%, so that’s what a close pays.
Minimum hold: 10 minutes
A short can’t be closed for the first 10 minutes after it opens.
- Why
- It stops open, dump, close in one go. Together with the average price, it takes the edge out of manipulating your own exit.
- Example
- You open at 12:00. The Close button unlocks at 12:10.
- Worth knowing
- Liquidation ignores the hold. If the price hits your line at 12:03, you’re out.
Two limits on size. The smaller one wins.
One new short can be at most 10% of the room left in the vault. On top of that, one wallet can have 1 SOL of open shorts up to a $50k market cap. Above that the limit grows with the market cap, up to 50 SOL: about 1.8 SOL at $100k, 7 SOL at $500k, 12.7 SOL at $1M and 50 SOL from $5M.
- Why
- The 10% share stops the first few wallets from filling the vault. When lots of people are short, everyone’s next short gets smaller; when the vault is topped up or shorts close, it grows back. The market-cap limit keeps one wallet from stacking short after short.
- Example
- The vault holds 20 SOL and 12 SOL is already shorted, so 8 SOL of room is left. The biggest new short is 0.8 SOL. At a $1M market cap your wallet limit is 12.7 SOL, so with 3 SOL open you could still add 9.7 SOL in total, one 0.8-or-smaller short at a time.
- Worth knowing
- Yes, you can use more wallets. Room-to-short still caps the total, so it can’t put the vault at risk.
Every buy is locked, and public
Losing SOL buys $GME on the coin’s own pool. Those coins go into a Met Lock contract for 2 weeks, then unlock to the dev wallet. Nobody can cancel the lock or change who gets it.
- Why
- The buy is what squeezes the price. The lock means none of those coins can be sold for 2 weeks, and anyone can check it on chain.
- Example
- A 1 SOL short is liquidated. The Activity tab shows the liquidation and the buy straight away. The lock tx follows within the hour, because locks go out in hourly batches.
What can go wrong
- Custody
- Stakes sit in a wallet the GameStop engine controls until the on-chain program ships. Every movement is public, but you are trusting the engine.
- Liquidity
- $GME trades on a pump.fun bonding curve, paired with GMEx. A thin pool moves fast, both ways.
- Wicks
- Liquidation uses the live price. Spikes count.
- Manipulation
- Anyone can try to push the price into the lines. Room-to-short limits the damage to what the vault holds.
- Memecoins
- $GME is a memecoin. It can go to zero. Shorts can win big; holders can lose everything.
