Launching

What the launch transaction does#

Everything below is one instruction, create_launch for a self-sponsored coin and launch for a queued one. It either all happens or none of it does.

1. Creates the coin on pump.fun with the vault (the coin's Launch account) as its creator. The creator (or the queue's cranker) pays pump.fun's create rent, as you would on pump.fun.
2. Funds the first buy. Self-sponsored: the amount you choose, 10 SOL to 50 SOL, no bond. Queued: the pool's one loan, 45 SOL, against the bond of max(0.05 SOL, 3% of the loan) you posted at submission, held apart from the floor money until the pool is repaid or writes the coin off.
3. Puts the whole first buy into tokens. The site sends pour_bps 0 and queued launches pour 0%, so nothing is set aside as ammo: the coin has no floor at launch. The floor starts with the vault's first sale into a pump and steps up from there. (The program still accepts a pour_bps up to 50%, which would skip the inventory buy and land as ammo, clamped so the floor sits at least 15% under the launch price.)
4. Makes the vault's buy the curve's first trade. No transaction can run between the create and this buy, so no sniper gets in under the vault. The buy is capped at 75% of supply and always stops short of the curve's sellable reserve; neither cap binds for a first buy in the allowed range, so all of it buys tokens.
5. Runs the second buy — your dev buy if you asked for one, or on a queued launch the committers' pooled SOL — after the vault's, so the vault always buys at the curve's lowest market cap.
6. Freezes the terms and the mode. The coin copies the platform's params and the mode you picked, and keeps them for life. Three of them are yours on a creator-funded launch: the sell threshold (1.3× by default for creator-funded coins, 2× for pool-funded; pick anywhere from 1.2× up to the platform's) and what the vault pays you back for the first buy. By default that payback comes later, from the floor: every sale builds the floor, and once the vault holds 5× the first buy in SOL a crank pays you back at cost, slowly — at most 10% of the ammo and a tenth of what you're owed every 4 hours, never while the floor is defending. Or take 125% of cost from the early sales of those tokens, or waive it. A third choice, under Advanced, is the floor's coverage: Tight (default) sizes the floor to hold a sell of 5% of the float, so it sits about twice as high; Deep holds 10%, a dump twice as big. A waived payback can never recall; a deferred one can only if the coin never ran, from 6 h after launch. Queued launches take the platform's 2× and 125%. The vault's reference is seeded with the spot right after its first buy.

The launch queue#

Pool-funded launches go through the queue: one bar per coin that the public fills to 10 SOL of credit, two ways at once.

1. Submit. Name, ticker, image, pitch, mode; the content check runs; you post the bond. The pool reserves its loan for your entry, and the entry appears on /queue with its own page and a code for every voter.
2. Fill. Commit SOL, or press Post to vote: the AI drafts a post with the queue link and your code, the X intent opens, you paste the post's link back. The vote shows Pending until the indexer finds the post on X, then Counted, or Rejected with the reason. Sorted by fill on /queue and in the landing page's Launching next strip.
3. Launch. At 10 SOL of credit anyone cranks launch (the Launch now button on the queue page): the indexer's attestor signs (queue, committed, post credit, expiry), the program verifies the signature against platform.attestor, then one transaction creates the coin, runs the vault's 45 SOL buy and the committers' buy — vault first, public second, nothing in between. With enough SOL committed alone, no attestation is needed.
4. Expire. Not filled within 1 day: anyone cranks expire. Commitments refundable, the pool's reservation released, and your bond back — unless fewer than 1 SOL was ever committed, in which case the bond is forfeited to the pool. Every submission restarts your 1 day creator cooldown, expired or not. Commitments stop at 3× the target (QueueCommitCap); an over-subscribed buy is capped one token short of the curve and the rest comes back as dust at claim.

Fund it yourself or queue it#

You enter amounts in SOL; the launch page shows their USD value next to them when a live SOL price is available. The pool can be off or at its cap; the launch page tells you before you sign, and self-sponsoring always works. Either way the first-buy SOL never becomes floor money: it is the sponsor's, it comes back only from its own tokens, and the sponsor page has the details.

The dev buy#

You can buy up to 5 SOL of your own coin in the launch transaction. It is a normal pump.fun buy paid by you, tokens to your wallet, executed right after the vault's. The program records it on the launch and emits a DevBought event (SOL spent, tokens, price after), so the coin page shows it as the creator's trade. It doesn't touch the vault, and the vault doesn't protect it: a dev who dumps sells into the market like anyone else.

Pick a mode#

Pick what your vault does. You can't change it after launch. Floor (the default) is 100% ammo: everything the vault earns bids a floor that only moves up, rationed so the bid lasts. Burn buys the dip and burns it; Pulse makes small buys when the chart goes quiet and sells them back into the next pump; Diamond sells nothing under 10× once the sponsor is paid. Burn, Pulse and Diamond keep half of the vault's fees as backing you can redeem at; Floor keeps nothing back. Compare the modes.

Where the creator fees go#

pump.fun pays a creator fee on every trade: on the bonding curve today 0.30% of volume, and in the PumpSwap pool after graduation a tiered rate that starts higher and steps down as market cap grows (pump.fun sets both). The vault is the creator, so it receives them, and the program splits them 80 / 5 / 10 / 5: 80% to your coin's vault, the rest to the AI treasury, the $LOADED buyback and burn, and sponsor-pool backers.

What it costs#

After launch#

• The coin trades on pump.fun like any other, and graduates to PumpSwap the same way.
• You can't withdraw from the vault, change the terms or pause the coin.
• What you can do: call collect_fees and sweep_fees yourself if nobody has lately, claim a refunded bond or a self-sponsored repayment with claim_sponsor, close a settled queue entry with close_queue, and point people at the coin page, where the vault is drawn live.
