The choices
| what it is | limits | |
|---|---|---|
| Name and ticker | your coin's name | 32 and 10 characters max |
| Image and links | stored in the coin's metadata, image pinned on IPFS | optional |
| Pair asset | what your coin trades against: a coin or a stock | must pass the depth test |
| Trading fee | taken on every trade, you keep 80% | 0.01% to 10%, 1% by default |
| Trading rules | up to six rules, set in the pool | optional |
| Dev buy | what you spend to buy your coin first | optional |
| Your share goes to | your wallet, buyback and burn, or your holders | see Fees |
The rest is set for you: a supply of 1 billion, an opening market cap of $4,000 (converted to the pair asset at its current price) and a price range with no ceiling.
A launch costs 0.002 ETH, read live from the contract. The code caps it at 1 ETH, so it can't quietly become a tax.
One signature, whatever the pair
You pay for everything in ETH, even if your coin trades against something else:
- ETH pair: your dev buy goes straight into the pool.
- Token or stock pair (USDC, AERO, NVDAc, a meme…): the ETH is swapped on the way through KyberSwap. For a stock, on its Aerodrome market.
It all happens in the launch transaction. You never hold the pair asset, nothing is left half done in your wallet, and if anything fails, nothing happens.
Why buy first
Your dev buy is the pool's opening trade, before anyone else can trade. You take the bottom of the range, and 80% of the fee you pay on it comes straight back to you.
It also has to happen inside the launch. The launchpad records the wallet that sends the transaction as the creator. A bot buying "for you" afterwards is just another buyer.
After the launch
You land on your coin's page: its chart, trades, holders, and the panel where anyone can buy and sell in ETH. Right after launch, the page waits for the chain to catch up, then fills in.
Your fees build up with every trade. Anyone can trigger a payout, and it can only go to you, or wherever you pointed your share.
If it fails
| message | what happened | what to do |
|---|---|---|
| Pair asset not eligible | its market is too thin for the depth test | pick another pair, or read Pair assets |
| Pool already initialized | someone opened your coin's pool before you | launch again, the form picks a new address |
| Price moved | the swap into the pair asset went past its limit | try again |
| Rejected in wallet | you said no | nothing was spent |
None of these costs you more than gas.
