vault – sol

Long or short a pump.fun coin
while it is still on the curve.

Pick a coin that is minutes old, stake SOL, take a side, up to 3x. The price is read from the bonding curve inside the transaction, at open and at close. One shared vault is the other side of every trade, and anyone can be the vault.

how it is settled
01

The curve is the price.

pump.fun keeps two numbers in every coin's curve account: virtual SOL and virtual tokens. Their ratio is the price. The program reads it when you open and when you close, in the transaction itself. No oracle, no server, no feed.

02

The vault is the other side.

Your stake goes into a shared vault. When you open, the vault reserves an amount equal to your stake, so the most you can win is always there. Profit is capped at your stake, loss is capped at your stake.

03

Leverage is a multiplier, nothing more.

pnl = stake × leverage × price move. At 2x a 10% move is 20% of the stake. At 3x a 33% move against you is the whole stake, and anyone can then liquidate the position.

what is honest to say
This is on devnet.

The program, the vault and the demo coin live on Solana devnet. Nothing here moves real SOL yet. Mainnet is one config line and a deploy, once the vault has real depositors.

A curve price can be pushed.

A fresh coin's curve is thin. Someone with enough SOL can buy, open a long, and sell after a minute. Three things limit it: the 150 slot minimum hold, the cap of profit at one stake, and the per-position limit of a quarter of the vault's free equity. It is a limit, not a cure. Deep pools are safer than thin ones.

Only coins still on the curve.

Once a coin graduates to PumpSwap the curve stops moving and the program refuses new positions on it. Open positions can still be closed at the last curve price. PumpSwap pools are the next thing to read.

The vault is depositors' money.

Every win is paid from what depositors put in. Every loss and every fee goes to them. There is no admin key that can take from the vault, and no fee to us. The program address is in the footer.
