Token Launch
Create a token on a launchpad and buy it with your wallets in the same block.
The main event. Token Launch creates a brand-new token on a launchpad and fills your wallets with it before anyone else can buy, in one block where the chain allows it.
Choosing a launchpad
On a chain with more than one, the form opens with a Launchpad picker, each option carrying that launchpad's own mark. See Launchpads for what each one fixes and what it leaves to you. Picking one changes every panel below it, so it comes first.
The form, panel by panel
Identity. Name, ticker, image, description and links. four.meme and Flap host the artwork themselves and refuse a launch without an image. OneMeme pins to IPFS, where a logo is optional. Blank links are omitted rather than sent empty, because at least one launchpad rejects an empty string where it accepts no field at all.
Curve or pool. Whatever the launchpad exposes. OneMeme offers graduation tiers and a raise asset, and a second shape entirely (a V3 pool launch, where the supply goes into a locked position instead of onto a curve). four.meme offers a raise asset. Flap and PONS fix everything and tell you what they fixed.
Creator. The wallet that signs the create transaction, and the size of its own initial buy. That buy runs inside the create, so it always gets the best price on the curve, ahead of every other wallet. The creator needs its buy plus gas for a heavy transaction: a four.meme create is around 3.5M gas, and a Flap create can be close to 6M because it also makes the pair.
Buy sizing. Either a total in the chain's coin, or a percentage of supply. The percentage is the more useful of the two: it says what you want to end up holding and lets the curve work out the cost. Distribution spreads it across wallets either equally or with a natural-looking jitter.
Slippage. Applied to each wallet's minimum output. The curve price rises with every buy in the bundle, so the wallets are priced in sequence rather than all at the opening price. A planner that quoted every wallet at the opening price would have the last ones fail their own minimum and revert.
Atomic bundle. On by default where a builder exists, off and disabled where none does, with the panel saying why. See Bundles.
Before you launch
The launch button stays disabled while anything is unresolved, and the reasons are listed under Before you launch. The common ones:
| Message | What to do |
|---|---|
| No RPC set | Settings |
| No funded buyer wallets | Fund them, or lower the gas reserve expectation by funding more |
| An image is required by this launchpad | Add one. four.meme and Flap will not sign without it |
| The buys would cross the graduation threshold | Lower the size. Crossing it mid-bundle reverts the last buys |
| The bundle cannot be prepared right now | The panel says why; usually the builder or the API is unreachable |
A separate, non-blocking warning appears when the creator wallet is also in the buyer book. It does not stop the launch, because the console drops the creator from the buys itself, but it is worth seeing: that wallet will not be buying twice.
Estimated cost
Priced through the same planner that will run the launch, so the estimate and the execution cannot drift apart. It itemises what the money is for, line by line:
| Line | What it is |
|---|---|
| Curve cost for the wallets | What the curve charges for that share of supply. This is the amount actually sent. |
| Held back as headroom | Your slippage setting, kept in the wallet rather than spent. The curve is read again at execution time and can have moved; whatever is not needed stays put. |
| Creator's own buy | A leg of the same bundle, out of the same wallet, spent exactly as entered. |
| Launch fee | The launchpad's own fee, read from its factory. |
| Create transaction gas | The creator signs one transaction on PONS that creates the token and runs every buy, so it carries the gas for all of it. |
| Creator wallet must hold | Everything above. The launch stops before it starts if the wallet is short, and the form says by how much rather than letting you press the button. |
| Still to send the wallets | Not spent on the launch. It is what each wallet needs later to sign its own sale, counted as a shortfall: a wallet that already holds enough adds nothing. Most of it comes back when you consolidate. |
On PONS the creator pays for the whole bundle in one transaction and the curve sends tokens straight to each recipient, so the buyer wallets need no balance to take part. Anything they are already holding is theirs, untouched, and counts towards the gas they will need to sell. On BNB Smart Chain it is the other way round: each wallet sends its own buy, so each needs its own buy amount plus its own gas.
A note on that last line, because it is easy to think it is too big. The chain reserves the whole gas limit at signing time, not the gas a transaction ends up using, so a wallet has to hold the limit or it cannot send the sale at all. That makes the limit the funding requirement. The limits are per venue and measured against real sales rather than set to one blanket number:
| Venue | A real sale uses | Signed with a limit of |
|---|---|---|
| PONS curve | 78,627 | 400,000 |
| PancakeSwap V2 | 115,099 | 900,000 |
| Four.meme curve | 173,771 | 600,000 |
| Flap curve | 280,982 | 700,000 |
The headroom covers what a plain token does not show: a fee-on-transfer token paying dividends on every sale, a curve that graduates mid-transaction, a first sale writing storage a later one reuses. Unused gas is refunded, so the limit costs nothing at execution.
On a curve the cost is not proportional to the share of supply, and it is worth seeing the shape before deciding a number looks wrong. The price rises with every token sold, so the first few percent are far cheaper than the last. On a PONS curve that graduates at 4.2 ETH:
| Share of supply | Curve cost |
|---|---|
| 1% | 0.0175 ETH |
| 2.5% | 0.0444 ETH |
| 5% | 0.0912 ETH |
| 10% | 0.1924 ETH |
| 25% | 0.5773 ETH |
| 50% | 1.7320 ETH |
| 71.43% (the whole sellable supply) | 4.33 ETH |
Doubling the target costs more than double, and the last few percent before graduation cost more than everything before them put together.
Each buyer wallet must hold its buy plus the full gas limit, not the expected gas but the limit, because that is what the chain reserves at signing time. On PONS the creator pays for every buy inside one transaction, so the buyer wallets need no balance at all.
What happens when it runs
The log shows every step, in order: the metadata upload, the address the token will get, the plan for each wallet, the bundle going out with each builder's answer, and the block it landed in. When it lands you get the token address, the create transaction, and each wallet's holding as a percentage of supply.
On four.meme there is an extra step worth understanding. The token's address is computed from a salt inside the payload four.meme's backend signed, and the console verifies that computation against the live contracts before it signs a single buy. If it cannot verify it, the launch stops rather than sending buys at an address that might not be created.
The run is recorded as a position. Go to Tokens to watch or sell it.
A landed launch cannot be undone
The token exists, the coin is spent, and the curve has moved. If the buys fail but the create succeeded, the console still reports the token: it is yours, and the creator's buy is in it.
