How the bank works.
Pump Bank is a thin frontend on top of pump.fun's creator fees on Solana, plus a worker that sweeps and distributes. No custom contracts, no custody of your coins.

The lifecycle of a member coin.
Issue
You sign one transaction. It creates your coin on pump.fun with the Pump Bank reserve set as the creator. That field is public, and neither you nor the bank can rewrite it.
Trade
Your coin trades like any other pump.fun launch. Every buy and sell pays a creator fee, and that fee goes to $BANK holders — on the bonding curve and after graduation alike.

Sweep
Every five minutes the reserve claims its creator vault. Because every member coin shares the same creator, one transaction collects the fees of the entire register, already denominated in SOL.

Pay
The reserve snapshots $BANK holders from the chain and sends every holder their share, weighted by balance, batched a few dozen per transaction. All of it on-chain, all of it logged.
Questions.
Where do the fees actually come from?
Every pump.fun coin pays a creator fee on each trade, and pump.fun sends it to the address set as the coin's creator. Coins launched through Pump Bank set the reserve as that creator, so 100% of those fees go to $BANK holders instead of to one person.
Can the fee routing be changed after launch?
Not by you, and not by the bank. The launch writes the reserve in as creator, and pump.fun pays that address. Only the protocol's own creator authority can move it later. Pump Bank reads the bonding curve and rejects any coin whose creator is not the reserve.
How do I earn as a holder?
Just hold $BANK in your own wallet. Every five minutes the reserve sweeps member-coin creator fees and sends every holder their pro-rata share in SOL, automatically. No staking, no claiming.
When does the reserve pay out?
The worker runs every five minutes. It distributes once the reserve holds at least 0.01 SOL; smaller amounts keep accumulating. Individual shares below 0.0001 SOL stay in the pot for the next round, and one run pays at most the 300 largest holders.
What does it cost?
Pump Bank charges nothing. Launching costs only what Solana and pump.fun charge for creating the coin; holding and receiving payouts costs nothing.
Is there guaranteed yield?
No. Distributions depend entirely on member-coin trading activity. No trades, no fees, no payouts. $BANK is a community memecoin, not a financial product.
