Thrown
A dev pays 0.02 SOL, names the coin and picks a picture. The supply is 1 000 000 000, fixed: the program drops the mint authority in the same transaction, so nobody can ever print more.
How it worksBoomerang
The whole rule, in the order you meet it. Nothing here is a promise about a price: it is what the program does, and the program is the only thing that can move the money.
A coin's day, in four pictures
Every coin on the pad goes through exactly this. There is no other path.
In the air
800 000 000 tokens sit on the pad's own curve. Buying moves the price up, selling moves it back down, and the SOL waits in the coin's safe. Sending tokens to another wallet is blocked until the coin bonds.
Hit
85 SOL in the safe inside 24 hours and the coin bonds at once: the safe's SOL and the 200 000 000 held back tokens go into a Meteora pool, the LP position is locked forever, and transfers open up.
Back in the paw
The 24 hours run out below 85 SOL and trading closes. The fees join the safe and every buyer takes back what they put in, one transaction for all their coins at once.
What you get back
The one number that decides it is your net contribution.
Net contribution
The program counts, per wallet and per coin, the SOL you spent on buys minus the SOL you got from sells. That number is what comes back to you, not the price, not the token balance.
If the safe is short
Somebody who bought early and sold high took SOL out of the safe. Then every refund is cut by the same factor, and the coin's page prints it: "the safe covers 94% of what buyers put in".
If you are already ahead
A wallet that took out more than it put in has a negative net contribution and gets nothing. You cannot take the profit and the refund.
How it reaches you
The keeper sends anything from 0.05 SOL up by itself and pays the gas out of its own share. Smaller amounts wait for you on Your returns. Unclaimed after 30 days, it buys $BOOMERANG and burns it.
The fees, and who is paid when
A dev is paid only if the coin makes it. That is the whole point of the pad.
| What | How much | Where it goes |
|---|---|---|
| Launch | 0.02 SOL | The pad. This one is never refunded. |
| Every trade | 1% | 0.1 percentage point goes to the keeper for gas at once. The other 0.9 waits in the coin's fee safe. |
| The fee safe, if the coin bonds | 100% | 50% the dev, 30% buys $BOOMERANG and burns it, 20% the pad. |
| The fee safe, if the coin comes back | 100% | Into the refund. Nobody is paid a fee on a coin that failed. |
| The pool's fees, after the bond | the pool's own rate | The same split: 50% the dev, 30% $BOOMERANG, 20% the pad. |
Why a rug is not possible before the bond
Three things, all of them enforced by the program and not by us.
The safe has no door
The SOL sits in an account only the program can sign for, and the program can only send it three ways: back to a buyer, into the locked pool, or, 30 days after a failure, to the $BOOMERANG burn. There is no withdraw.
The supply is fixed
The whole 1 000 000 000 is minted once into the curve's vault and the mint authority is dropped in the same transaction. There is no second mint and no dev allocation.
Transfers are locked until it bonds
A Token-2022 transfer hook lets a trade through the curve and nothing else, so nobody can move tokens between wallets to be counted twice. After the bond the hook lets everything through, forever.
What we can change
The pad's admin can change the fee and the threshold for coins launched later, and can pause new launches and buys. It cannot pause selling, expiry or a refund, and it can never touch a coin already in the air.
$BOOMERANG itself
The pad's own coin, and the only thing on this site that is not a coin on the pad.
$BOOMERANG is launched on pump.fun. It is not on this pad and has no 24 hour clock: it is what 30% of every fee on the pad buys and burns. The more coins fly, the more of it is taken off the market. Its contract sits on the front sheet, and nothing about it is promised here beyond the burn the program pays for.
