How the tower works
The tower
$BELOW trades against SOL on pump.fun. Under it, the tower grows one floor at a time. Every floor is a coin created on pump.fun paired with $BELOW: its bonding curve is priced in $BELOW, it graduates into a PumpSwap pool against $BELOW, and its creator fees are paid in $BELOW.
So every buy of any floor is a buy of $BELOW first. The deeper the tower, the more of its trading flows into $BELOW.
The queue
Anyone can put a coin in the queue: a name, a ticker, a picture. It waits with a … deposit. Take it out any time and the deposit comes back. When it opens a floor, the deposit pays the opener back for the launch. You stay the coin's creator.
The gate
The next floor opens when the floor above it (for the first floor, $BELOW itself) holds a market cap of … for … in a row. A dip below resets the clock.
The draw
When the gate is passed, a draw picks a $BELOW holder, weighed by balance. Nothing to sign up for: every wallet holding at least … $BELOW is in. The randomness is the latest Solana slot hash, written on chain when the draw starts, and the holders are snapshotted at that moment.
The winner has … to pick any coin from the queue and open the floor. If they don't, the floor is drawn again. After … draws without a pick, the oldest coin in the queue opens the floor.
Anyone can check a draw: the snapshot's holders sorted by wallet address, each a stretch of a line as long as its balance; the point is the seed's first 16 bytes modulo the total. Every draw page recomputes it in your browser.
Fees
Every floor launches with a … creator fee on pump.fun, paid in $BELOW. It is split for good at the launch, by pump.fun's own fee sharing, and nobody can change it afterwards:
- … to the coin's creator (the wallet that queued it);
- … to the holder who opened the floor (to the burn when the keeper did);
- … burned: the vault's $BELOW is burned, removed from the supply.
pump.fun's own trading fees apply on top, as on any pump.fun coin.
A floor that sinks
If the top floor does not pass the gate within …, it leaves the tower. The coin keeps trading on pump.fun and its fee split stays, but its floor is drawn again and a new coin takes it.
Trading
Buy and sell any floor for SOL right here: one transaction goes SOL → $BELOW → the floor through the Belowpad program on pump.fun, and back the same way. Every floor trades on pump.fun too.
Risks
Memecoins are volatile, and can go to zero. Every floor is priced in $BELOW, so a fall of $BELOW pulls every floor down with it. A buy deep in the tower pays fees on each hop of its route.
Smart contracts can have bugs. Nothing here is financial advice. Only spend what you can afford to lose.
