What a launch needs
- A name of up to 32 bytes and a ticker of up to 10, counted in bytes the way the mint does.
- A description of up to 400 characters, frozen into the coin's metadata.
- A square icon of at least 256 pixels and a 3 to 1 banner of at least 600 by 200, both PNG, JPEG or WebP, read from their bytes rather than their file names.
- At least one link. A website is fetched from the server to prove it answers; an X profile, a Telegram or a Discord invite is checked by its shape, because those hosts answer bots with a wall.
The 3% rule
The buy inside the launch transaction may take at most 3% of the total supply. The form prices it on pump.fun's curve at creation, fees included, and refuses anything over the line.
It is a cap on the launch buy only. There is no cap on what the creator holds later: after launch everyone, the creator included, buys on the open curve.
Where the fees go
The split is written into the coin's fee-sharing config at the mint and the admin is revoked in the same instruction, so it cannot be edited afterwards. Every coin launched here carries this split:
| Share | Goes to |
|---|---|
| 70% | the coin's own promotion wallet |
| 15% | the creator |
| 15% | Stoke |
The promotion wallet spends in a fixed order:
- Enhanced Token Info
- Boosts
Later, a creator will be able to reserve a share for token ads and trending bar ads. Prices come from DEX Screener's catalog at the moment of each purchase and are never quoted in advance.
The promotion meter
Every coin page carries one meter in three phases. It fills from the coin's spendable fees only; reserved fees never count toward the next purchase. Earned, claimable, spendable, reserved and spent are shown separately, and every purchase is listed with its transaction.
The three below are samples with made-up amounts, not coins and not prices. Payment confirmed on chain is not the same as DEX Screener processing it, so the paid phase walks through review before it says live.
- Earned
- 1.31
- Claimable
- 0.22
- Spendable
- 0.84
- Reserved
- 0.25
- Spent
- 0.00
- Paid
- In review
- Live

This build
Launches run on mainnet-beta. The form checks and prices a launch on the server and answers with its plan; where launching is switched on, the worker pins the metadata and builds the create with its split and your first buy, and your wallet signs it.
Trades on a coin page are real swaps through Jupiter on mainnet, quoted on the server and signed by your own wallet. The site never holds a key and never signs for you.
Promotion purchases are not switched on yet. The worker tracks each coin's promotion wallet and plans what it would buy; it buys nothing on DEX Screener until the owner turns the engine on.
Stoke is not affiliated with pump.fun or DEX Screener.
