How a breath travels
The flow
- 1. Seed: name, ticker, description, optionally grown with AI
- 2. Image: upload or paint with gpt-image-2
- 3. Socials: optional links, written into the token metadata
- 4. Breath: choose a dev buy (no cap, up to the 80 SOL curve limit), its lock mode and length, slippage and priority; a live trust preview and an AI advisor help you pick the lock
- 5. Release: the guard checks your wallet, metadata is pinned, PumpPortal builds the create transaction, you sign, it confirms, and the launch is recorded on pappus after we verify it on-chain; a dev buy is then locked in Jupiter Lock with one more signature
Fees, exactly
pappus charges nothing; every other fee is charged by the protocols your transaction uses and shown before you sign
The guard
What pappus enforces, what it only flags, and what nobody can stop
Minimum lock
By the dev's share of total supply, measured from the launch to the last unlock
Trust score
- 45 for meeting the minimum, plus up to 30 for length (10 per doubling past the minimum)
- Plus 15 for a gradual unlock and up to 10 for a small share; no dev buy scores 100
- One Meadow point per 5 trust points above 45
- The AI advises on the terms and phrases the pledge, it never sets the score or the minimum
Enforced on-chain
- Every token of a dev buy goes into Jupiter Lock (audited, open source) right after the create, on the schedule the dev picked: full unlock at the end, or gradual unlock hour by hour
- The minimum lock grows with the dev's share of supply (see the table); pappus won't build a create or a lock below it
- Nobody can cancel the lock or change who receives it, not the dev and not pappus
- The lock is a second transaction: until it lands the token shows unlocked dev
Detected and flagged
- Before a launch: the creator wallet's history is checked; 2+ earlier launches dumped within a day, or 8+ brand new wallets funded in 24 h, block the launch; weaker signs only warn
- After a launch: sells from the dev wallet and from wallets it funded in the day before launch mark the token dev sold or linked wallets sold
- Flags cost Meadow points: unlocked dev −20, dev sold −35, linked wallets sold −20
- Locks earn points: the trust score (rules: lock length past the minimum, gradual unlock, small share) adds up to +11; no dev buy counts as the strongest
Can't prevent
- Tokens the dev buys later from other wallets, or wallets with no visible link to the dev
- Selling after the lock unlocks
- A launch made outside pappus with the same wallet: the check reads recent history and can miss older patterns; a failed check lets the launch through with a warning
$PAPPUS
The only contract address is the one shown here, in the site header and on our XAlways check it before you buy
What is pappus?+
A Solana launchpad for fair launches on pump.fun's bonding curve
One guided flow where every token of the dev buy is locked on-chain, and a live Dispersal map and score for every token, built from its on-chain holders
Is the token really created on-chain?+
Yes: PumpPortal's Local Transaction API builds pump.fun's own create instruction (a Token-2022 mint, same as a launch on pump.fun)
A fresh mint keypair is generated in your browser; your wallet signs first, the mint key co-signs, and the transaction is broadcast through our RPC relay
pappus never sees your private key and never holds funds; the mint key exists only in your browser for the few seconds it takes to sign
After that the token lives on pump.fun like any other
How big can the dev buy be?+
There's no cap: buy as much as your wallet can pay for, up to 80 SOL (about 78% of supply), where the pump.fun curve would graduate inside the create
The dev buy runs in the same transaction as the create, so nobody can front-run it, and the launch flow shows your share of supply live
Every token of it is then locked in Jupiter Lock; the bigger your share, the longer the minimum lock, see the guard below
How does the dev lock work?+
Full unlock at the end: everything stays locked until the end date, then unlocks at once
Gradual unlock: equal portions every hour across the period, from launch or after a 1, 3, 7 day cliff you pick
Lengths: 7, 14, 30, 60, 90, 180 days, never below the minimum for your share; nobody can cancel the lock or change who receives it
Buyers see the dates on the token page, with a link to the lock account on Solscan
What does the AI do in the guard?+
It advises and it phrases, it never decides
On the Breath step it suggests lock terms in 2 or 3 lines and says how yours read to buyers; a suggestion below the minimum is dropped
Once the lock lands it phrases a short public pledge; the share and dates come from the lock account and are checked word by word, otherwise a fixed template is used
The minimum lock, the trust score, the wallet check and the Meadow points are plain rules
What does a launch cost, exactly?+
Without a dev buy: about 0.0056 SOL plus your priority fee
With a 1 SOL dev buy: 1 SOL into the curve + 1.25% pump.fun fee + 0.5% PumpPortal fee = 1.0175 SOL, plus rent: about 1.0260 SOL plus priority
The confirm step shows your own numbers before you sign
All figures come from simulating real create transactions on mainnet
Do I earn anything as the creator?+
Yes, from pump.fun, not from pappus: 0.3% of every bonding-curve trade of your token goes to your wallet's creator rewards on pump.fun, claimable there
pappus takes nothing either way
How is the dispersal score calculated?+
Helius DAS reads every token account (up to 8,000), grouped by owner; program-derived owners are dropped: bonding curves, AMM pools, lockers
score = 40% × (1 − Gini) + 35% × (1 − top-10 share) + 25% × breadth, where breadth = log₁₀(holders) / 4 (10,000 holders fills it)
75+ is a "Wild meadow", under 25 is "Heavy seeds"
Snapshots refresh as tokens are viewed and once a day
Where is the metadata stored?+
First choice: pump.fun's own IPFS pinning, where pump.fun stores its tokens' metadata
If that is unavailable we host the image and JSON ourselves at a permanent URL, so a pinning failure never blocks a launch
Can I trade here?+
Yes: tokens on the curve trade through PumpPortal, graduated tokens through Jupiter
Amount, fees, minimum received, slippage and route are shown before you sign, with a Solscan link after
Does AI cost me anything?+
"Grow it with AI" and "Paint it with AI" are free, with a daily limit per visitor: 20 seeds and 6 images
Names and lore come from a GPT model, images from gpt-image-2
What is the growth plan?+
A 7-day plan for your token, written by AI from its name, lore and live stats: posts, community steps, holder and dispersal milestones and what to avoid
Only the creator sees it, after signing a message with the creator wallet: no transaction, no fee; others only see that a plan exists
3 plans per token per day and 5 per wallet per day; it never talks about price and it isn't financial advice
Risks
- Memecoins are extremely volatile: most go to zero, often within hours; only use money you can afford to lose
- A launch is final: once the transaction confirms, the token exists on Solana and its name, ticker, image and links cannot be edited or deleted
- Rent and fees are spent even if nobody buys your token
- A dispersal score describes holder distribution at the time of the snapshot; it is not a safety rating, an audit or a prediction
- The guard lowers rug risk, it doesn't remove it: see what it enforces and what it can't stop above
- pappus relies on pump.fun, PumpPortal, Jupiter, Helius and IPFS: if one of them changes or goes down, launches or trades can fail until it recovers; nothing is ever sent without your signature
- Anyone can launch anything: pappus does not vet tokens, creators or their claims, do your own research
- Nothing on pappus is financial, investment, legal or tax advice; you are responsible for what you launch and trade, and for following the law where you live
