A bank that doubles your launch.
Dev Bank is a launchpad-bank built on top of the Pump.fun fee-share protocol. It mirrors every dev's stake 1:1 — you bring N SOL, the bank lends you another N in the same transaction. Pump.fun fees from your token automatically repay the loan. Holders of $DEV earn the spread.
Mirror your stake
Deposit N SOL → receive an N SOL marketing loan. Your deposit is locked as collateral until the debt clears.
Fees repay the loan
Your token's creator fees route into a program-controlled PDA. Pump.fun pays the bank automatically.
Holders earn the spread
Interest, fee-cuts, and $DEV creator fees flow to $DEV holders pro-rata, every 2 hours, in SOL.
The math
For the dev. A 5 SOL deposit becomes 5 SOL of working capital on day one — twice the firepower for the same out-of-pocket commitment. When the loan is repaid, your deposit is returned. Net cost: just the interest.
For the bank.Every loan is matched 1:1 by the dev's deposit, so the bank's exposure starts at zero. Worst case (default): collateral plus the locked supply slice cover the loss. Best case: the bank earns interest plus its cut of the fee stream.
For $DEV holders. Holders receive 70% of all profit pool inflows in SOL, every 2 hours. The remaining 15% / 10% / 5% go to buyback, insurance, and protocol treasury respectively.
