Everything about how PUMPSTOCK works — for launchers, holders, traders and integrators.
Overview
PUMPSTOCK is a launchpad on top of pump.fun for bank coins: coins that pay their holders. pump.fun now lets a coin trade against a quote asset other than SOL — tokenized stocks like Gold, the S&P 500 or NVIDIA, Bitcoin, or USDC. When a coin is paired that way, its creator fees are paid in that asset.
PUMPSTOCK keeps the creator wallet of every coin it launches and runs the bank engine on it: every cycle it claims the fees and airdrops 90% of them, pro-rata, to every qualified holder. Jeets fund the vault; holders collect the dividends. No staking, no claiming, nothing to sign.
Paired assets
The launch form offers the quote assets pump.fun currently accepts and that we have verified end to end: xStocks (GLDx, SPYx, NVDAx, HOODx…), Backpack Securities stocks (SPCX, TTWO…), WBTC and USDC. The engine is asset-agnostic — it reads the coin's quote mint on-chain, its token program and decimals, and prices it via Jupiter — so new assets are a config change, not a code change.
Opening a bank
Go to Open a bank, pick the asset, fill in name, ticker and image, set an optional dev buy, and send ONE plain SOL transfer (dev buy + network costs — no launch fee). PUMPSTOCK launches from a fresh custodial wallet: the dev-buy SOL is swapped into the asset via Jupiter, the coin is created on pump.fun paired with that asset, and the dev-buy tokens are forwarded to your wallet. The fresh wallet keeps only the creator role — that is what makes it the bank.
Part of the transfer stays in the bank wallet as a gas reserve: it pays the claim transactions and the token-account rent for holders who don't have an account for the asset yet. If a launch fails, the deposit is refunded automatically.
Drops
- Every 5 minutes the engine reads the coin's creator-fee vaults (bonding curve and, after graduation, PumpSwap).
- When the unclaimed fees are worth at least $1, it claims them into the bank wallet — in the asset.
- 90% is split pro-rata among qualified holders by their balance at that moment; 10% goes to PUMPSTOCK.
- Each holder receives a transfer of the asset. Every claim and every payment is a public transaction linked from the coin page.
Holders without a token account for the asset: the bank creates it (paying the ~0.002 SOL rent) when their drop is worth at least that much, or after 10 consecutive skipped drops — at most once per wallet. You can always create the account yourself to receive immediately.
Who gets paid
A wallet qualifies when it holds at least 0.02% of supply (200,000 of the 1B tokens) at snapshot time. Wallets at or above 3.8% of supply are excluded — the bank serves the community, not mega-whales. The bonding curve, the pool and the bank wallet itself never receive drops.
Fees & liquidity
Coins trade on the pump.fun bonding curve until it completes, then graduate to PumpSwap like any pump.fun coin. Trading fees are pump.fun's standard ones; the creator share is what the bank distributes. PUMPSTOCK charges no launch fee and keeps 10% of each claim.
The engine
Launches run through the official pump.fun program (create + dev buy). Buy/sell from the coin page trades directly on the bonding curve with your own wallet, paid in the asset — nothing custodial. The custodial part is exactly one thing: each coin's creator wallet, encrypted at rest, which only ever claims fees and pays holders.
