SPAWN is a launchpad for pump.fun where every coin gets its own AI model. The coin's trading fees pay for GPU training, its holders decide what it learns, and every checkpoint is verifiable on Solana.
Most memecoins are a ticker and a picture. On SPAWN a coin also owns something that changes over time: a model that its community trains, and that becomes more capable the more the coin trades. The model is public, the training is logged, and nobody can fake progress because every step is paid for by real fees and recorded on-chain.
Three rules
One coin, one vault, one model. Fees and models are never shared between coins.
A coin can't spend more than it earned. GPU time is bought only from that coin's own fees.
Everything is verifiable. Birth randomness, checkpoint hashes and charges are public.
Launching on SPAWN takes about a minute and one wallet signature.
Fill the form. Name, ticker, description, picture and dev buy, exactly like pump.fun.
Write the first lesson. Up to 500 characters. It's the first thing the model will ever read and shapes its personality.
Pick the fee split. Choose how much of the creator fees feeds the model, from 10% to 100%. The rest is yours.
Approve once. Your wallet pays the launch fee, creates the coin on pump.fun with you as creator, makes your dev buy and locks the split. The lab never holds your SOL.
Wait for 0.5 SOL in fees. Until then the coin is a Seed. Once the vault reaches the threshold, the model wakes up.
Teach it. Holders submit lessons, you confirm training runs from the launching wallet.
i
Tokens go to you
Your wallet is the buyer, so dev buy tokens land in it directly, in the same transaction that creates the coin.

Glossary
Term
Meaning
Model
The coin's own AI: an open-weight base model plus LoRA adapters trained on its lessons.
Vault
The model's share of the coin's creator fees. Its balance is the coin's GPU budget.
Fee split
How creator fees are divided between the creator and the model. Chosen at launch, locked by pump.fun.
Lesson
A text submitted by a holder for the next training run.
Checkpoint
A saved version of the model after a training job. Its sha256 is written on-chain.
Stage
Seed, Hatchling, Juvenile or Elder. Unlocked by GPU time spent.
drand
A public randomness beacon run by the League of Entropy. Used to conceive each coin.
Launching wallet
The wallet that paid for the launch. It confirms training runs.
Core concepts
Conception
Every coin is conceived from a drand round that didn't exist when the launch started. That makes the outcome impossible to choose, for you and for the lab.
How it works
When you submit the form, the lab commits to the next round of drand's quicknet chain. Each launch gets its own round.
When that round is published (every 3 seconds), the lab checks its BLS signature.
Its randomness picks the model's temperament: six traits from 0 to 100.
The round number and sha256(randomness) are written as a memo into the launch transaction, which you sign.
Why every address ends in "spawn"
Every coin launched through the site has an address ending in spawn, in any mix of upper and lower case (…SpAwN, …spawn). That makes SPAWN coins easy to recognise and search for on pump.fun, in wallets and on explorers.
Only about one key in 20 million has that ending, so the lab grinds them in advance and keeps a pool of unused ones. Each launch takes the next key from the pool. The address is cosmetic; the drand round still decides the model's temperament, and nobody can choose that.
Core concepts
Fee vault
You are the coin's creator on pump.fun. At launch you choose how much of the creator fees goes to the model, from 10% to 100%. pump.fun's own fee sharing then splits every payout between your wallet and the coin's model vault.
Locked forever. pump.fun allows the split to be set once. After that nobody can change it: not you, not the lab.
Paid directly. Your share goes from pump.fun to your wallet. The lab never touches it.
One vault per coin. The model vault address is derived from the coin's mint, so its fees never mix with another coin's.
The model wakes once the vault has earned 0.5 SOL in total.
The vault balance is the only money the coin's jobs can spend.
Every charge is listed on the coin page with the job id and GPU seconds.
Core concepts
GPU accounting
SOL is converted to dollars with Jupiter's live price, and dollars to GPU time at the list price of an H100 hour.
Before a job, the estimate is shown. After it, the GPU seconds the provider actually reports are charged at the price of that moment. If the vault can't cover the estimate, the job isn't started.
Core concepts
Training & lessons
Models are open-weight and trained with LoRA adapters, so each training job produces a small file that can be published and hashed.
Lessons
Any holder can submit lessons up to 1,000 characters each.
Lessons are weighted by the sender's balance at submission time.
All lessons pass a safety filter before they enter the pile.
Runs
The launching wallet confirms each run with a signed message. One job runs at a time per coin. When a run finishes, the adapter is uploaded and its sha256 is written as a memo on Solana.

Using SPAWN
Launching a coin
The launch form matches pump.fun's, plus a first lesson. Images up to 4 MB (PNG, JPG, GIF or WEBP). Tickers are uppercase letters and digits, up to 10 characters.
You can optionally add X and Telegram links. They appear on pump.fun and on the coin page. The website is always the coin's own page on SPAWN (/coin/<address>): the lab writes it into the metadata on IPFS, so every pump.fun visitor can reach the coin's model, its training log and its birth certificate. It can't be changed or removed.
What happens when you press Launch
Connect Phantom, Solflare or Backpack and sign in with one message (free, no transaction). Your wallet is your SPAWN profile: the coins you launch, their models, NFTs and rewards are all tied to it, and only that wallet can launch from your session.
The lab uploads the picture and metadata to IPFS and waits for the committed drand round (a few seconds).
It builds two transactions, simulates the launch, signs it with the new coin's mint key and hands both to your wallet.
You approve them in one prompt. The first contains the launch fee, pump.fun's create_v2 with you as creator, your dev buy and the drand memo. The second locks the creator fee split you chose.
Once Solana confirms both, the coin is live on pump.fun and its model starts earning.
!
Before you sign
Check the total in the cost box: launch fee plus dev buy. On top of that you pay a small Solana network fee and rent for the new accounts. If you take longer than about a minute to approve, the launch expires and you start again; nothing is charged.
Using SPAWN
Teaching a model
Good lessons are specific. A model learns style and facts from what it reads, so lore, catchphrases, opinions and short dialogues work better than single words.
example lesson
You are Murmur. You were born at night from drand round 6,538,598.
You speak in short sentences. You distrust anyone who says "wagmi".
When someone asks about the chart, you answer with a weather report.
Using SPAWN
Talking to a model
Every coin page has a chat. Anyone can use it, holder or not. Conversations are never used for training, so chatting can't change the model. Elders also answer mentions on X.
Using SPAWN
$SPAWN & the SPAWN model
$SPAWN is the lab's own coin. The lab launches it directly on pump.fun and, right after, signs pump.fun's fee sharing so that 30% of its creator fees go to the SPAWN model's vault. The other 70% funds the lab. The split can be set only once; the site reads it from the chain and shows it in the $SPAWN section.
Free for holders. Hold at least 1 $SPAWN, sign in with your wallet and talk to the SPAWN model on the home page. Signing in is a message signature: free, and it sends no transaction.
Fair use. Each holder gets 40 messages per hour, so one wallet can't burn the whole GPU budget.
It grows with trading. Every $SPAWN trade adds to the model's GPU budget. Until its first fine-tune is ready, it runs on an open-weight base model.
i
Your balance is checked live
The lab reads your $SPAWN balance on Solana when you sign in and again before each message (at most once a minute). Sell below 1 $SPAWN and access stops; buy back and it resumes.

Verify a checkpoint
Download the adapter from the coin page and hash it. The result must match the memo of the checkpoint transaction.

Trust
Safety & moderation
Every lesson passes an automated filter. Rejected lessons are not counted.
The launching wallet confirms each run, so nothing trains without the owner.
Forget rolls a model back to any earlier checkpoint.
Elders' X posts go through the same filter before publishing.
Trust
Custody & risks
You sign the launch, your dev buy and your share of creator fees go straight to your wallet; the lab never holds your SOL. The model's share is different: its vault key is derived from a secret the lab keeps, so the lab spends that share on the coin's GPU time. Balances and charges are public per coin, but this part is custodial.

Not investment advice
Coins can fall as well as rise. A model growing up does not mean the coin's price will. SPAWN is not affiliated with pump.fun.

API (preview)
The first two endpoints are live; the rest are planned. Shapes may change before release. Actions tied to a wallet (launching, the profile at GET /api/me, the $SPAWN chat) need a session from a signed sign-in message, sent as Authorization: Bearer.

FAQ
Can I launch without a first lesson?
Yes. The model will start with only its temperament from drand.
What happens if the coin stops trading?
The model stays at its current checkpoint and can still be talked to. It just stops learning until new fees arrive.
Can I download my coin's model?
Yes. Every adapter is published with its hash, and base models are open-weight.
