How pmup
actually works.

On pump.fun, creator fees go to whoever launched the coin, and what they do with them is up to them. On pmup every coin gets its own fee vault, and the launch mode decides, up front and permanently, what that vault pays for. Most modes spend the fees buying the coin back: some burn what they buy, some add it to the PumpSwap pool and burn the LP tokens so that liquidity is locked for good.

What stays exactly the same as any pump.fun coin:

• Created with pump.fun's own program, 1,000,000,000 tokens, on the standard bonding curve.
• Graduates to a PumpSwap pool when the curve completes, around 85 SOL.
• Shows up and trades on pump.fun, PumpSwap and every Solana wallet and explorer.

What you fill in

Instant launch

pmup builds a single transaction that creates the coin on pump.fun and, if you set one, makes your initial buy (up to 50 SOL) in the same transaction. You sign once and pay the network fee. The coin is live the moment it confirms, and its page opens straight away.

The coin's pump.fun creator is set to its own fee vault, not your wallet. That is what lets the keeper route its fees by the mode you picked. Any creator share in your mode is paid to the wallet that launched.

Fair launch

Choosing a fair launch mode opens a pool instead of minting. You pick a pool cap and a window, wallets commit SOL, and the coin is created and bought in one transaction when the window closes. There is no initial buy for the creator: you join the pool like everyone else. How the pool works.

Side by side

1. 1Open

   The creator sets a pool cap and a window. Nothing is minted yet.

2. 2Commit

   Wallets send SOL to the pool, at most 0.5 SOL each, until the cap is reached.

3. 3Close

   The window ends, or the pool fills early.

4. 4Settle

   One transaction creates the coin and buys with the whole pool. Allocations are pro-rata.

Committing

A commit is a plain SOL transfer from your wallet into the pool's escrow, signed in your wallet from the coin page. The minimum is 0.01 SOL. You can commit more than once until you reach the 0.5 SOL wallet cap or the pool is full.

Settlement

When the window closes, or as soon as the pool is full, the pool settles: a single transaction creates the coin on pump.fun and buys with all the pooled SOL. Every committer gets tokens in proportion to what they put in, so the first buyers all pay the same price and nobody front-runs the floor.

Settlement happens on its own. The keeper settles due pools on every pass, the coin page triggers it when it sees a closed window, and anyone can trigger it once the window is over.

Each tranche releases 20% of your allocation. The first is available as soon as the pool settles; the rest open at 250, 500, 1,000, 2,000 unique holders. Holder counts come from Birdeye.

Unlocked tokens are claimed from the coin page with one click: the claim sends whatever is unlocked and not yet claimed to your wallet. Claim as often as you like.

On the curve vs after graduation

The venue decides how the buy is made. On the bonding curve the keeper buys from the curve; once the coin has graduated it buys from the PumpSwap pool and can pair liquidity. While a coin is still on the curve there is no pool to pair into, so the liquidity share is burned along with the burn share. Pure liquidity modes with a wait rule are the exception: the keeper skips them and their fees build up in the vault until graduation.

Fair launches settle themselves

Before injecting, each pass settles any fair launch whose window has closed or whose pool is full. Nobody has to press anything: the coin mints (or the pool refunds) on the next pass after the window ends.

Running it

The keeper runs as its own process next to the site, reads the same environment, and talks to the chain and the database directly. No cron and no web server are involved.

$ pnpm keeper            # loop forever, one pass every 60s
$ pnpm keeper --once     # a single pass, then exit
$ pnpm keeper <mint>     # a single pass for one coin

One vault per coin

At launch every coin gets its own fee-vault key, derived for that mint alone, and it is set as the coin's creator on pump.fun. pump.fun pays the coin's creator fees to that vault, so each coin's fees can only ever be spent on that coin's own mode.

Guarantees in the code

• A sweep moves only what the collect just added. The vault's own SOL is never touched.
• Only tokens bought in the current pass are burned or paired, never other keeper holdings such as unclaimed fair launch allocations.
• LP tokens from every deposit are burned in the same pass, so added liquidity cannot be withdrawn.
• Creator shares go to the wallet that launched the coin, in the same pass the fees were collected.

On the curve

The trade panel quotes against the live curve and builds the transaction for you to sign in your wallet. Buys are entered in SOL, sells in tokens, with 2% slippage. Every trade pays pump.fun's normal fees, including the creator fee that feeds the coin's vault.

Graduation

When the curve completes, at around 85 SOL, pump.fun migrates the coin to a PumpSwap pool. The coin page switches to a link to trade there, and the keeper carries on against the pool: from now on liquidity shares are paired in and the LP is burned, and modes that were waiting pair their whole vault balance.

Market cap counts circulating supply: the 1,000,000,000 total minus every token the keeper has burned. Fair launch coins also show the unlock ladder and how many holders the next tranche needs.

Bonding curve

pump.fun's pricing curve. Every coin starts on it; price rises as SOL comes in.

Graduation

When the curve completes (around 85 SOL) and the coin moves to a PumpSwap pool.

PumpSwap

pump.fun's AMM, where graduated coins trade.

Creator fee

The share of every trade pump.fun pays to a coin's creator. On pmup it goes to the coin's fee vault.

Fee vault

A key unique to each coin, set as its pump.fun creator, that receives its creator fees.

Launch mode

The fixed choice of launch type and fee split for a coin.

Keeper

The process that executes every coin's launch mode every 60 seconds.

Injection

One keeper pass for one coin: collect, split, buy, pair, burn.

Fair launch pool

A capped-wallet pool that buys a coin's floor in one transaction.

Holder-gated unlock

Fair launch allocations released in tranches as unique holders grow.

LP burn

Destroying LP tokens after a deposit, so the liquidity can never be withdrawn.

wSOL

Wrapped SOL, the token form PumpSwap pays fees in. The keeper unwraps it.
