Launching a token
One transaction creates the token, opens its market and, if you want, makes your first buy - atomically, so nobody can trade ahead of you. This page walks the flow end to end and is precise about the single most important fact: which decisions are permanent.
Before you launch
- Launch fee
- 0.002 ETH
- Default supply
- 1,000,000,000
- Default target
- 4 ETH raised
- Default swap fee
- 1.00%
- Dev-buy cap
- 2% of supply
- Time to launch
- 1 transaction
You need a wallet connected to the launch chain with enough of its native coin for the flat launch fee (0.002 ETH on Robinhood Chain) plus gas, plus whatever you want to spend on an optional dev buy. There is no allowlist, no approval step and no coding.
The defaults reproduce the classic launchpad experience: 1B supply, a curve that graduates after 4 ETH of net buys, anti-sniper protection on, fees paid to you in ETH. Every one of those is adjustable - see Every launch option - but nothing forces you into the advanced section.
The launch flow
- Venue. Pick the chain first - it decides which options exist on the rest of the form. Chains marked “coming soon” can be joined via waitlist but not launched on. See Chains & venues.
- Identity. Name, ticker, image, description, and optional links (website, X, Telegram). Name and ticker go on-chain and are permanent - the rest is metadata you can edit later.
- Economics (optional). Total supply, opening market cap, your swap fee, fee routing, anti-sniper, dev buy. All immutable after launch.
- Review & deploy. The summary shows the exact fee, the dev-buy quote and every setting. One wallet confirmation deploys everything.
What happens on-chain
In the single launch transaction, the launchpad contract:
- deploys your token and mints the entire supply to itself - you never hold un-earned supply, and neither does anyone else;
- initialises the bonding curve with your supply and opening reserve (the maths);
- creates the token's future Uniswap pool immediately and instructs the token to block transfers to and from that pool until graduation - so nobody can set up a side market while bonding is under way;
- records your immutable launch configuration (supply, curve, fee, routing, anti-sniper) and emits it in public events any indexer can read;
- takes the flat launch fee for the platform treasury;
- executes your optional dev buy at the very start of the curve.
The token itself is a deliberately boring ERC-20: fixed supply, no mint function, no pause, no fees inside the token. Its only special behaviour - the pool block - is removed at graduation, when ownership is renounced and it becomes fully immutable.
Permanent vs editable
This table is the one to read twice. “Permanent” means no admin, creator or upgrade path can change it for a launched token.
| Setting | Permanent? | Notes |
|---|---|---|
| Name | Permanent | A constructor argument of the token contract. |
| Ticker | Permanent | Also a constructor argument. Choose carefully. |
| Total supply | Permanent | Minted once at launch; no mint function exists. |
| Opening market cap | Permanent | The curve keeps the reserve snapshot it launched with. |
| Swap fee | Permanent | The contract writes it exactly once, at launch. Not even an admin can raise a live token’s fee. |
| Fee routing | Permanent | ETH-side and token-side destinations are fixed at launch. (The stock route is a preview for now - it opens, together with its separate ticker election, after the stock rail’s audit.) |
| Anti-sniper | Permanent | On or off for the life of the bonding phase. |
| Quote asset | Permanent | A curve denominated in ETH stays in ETH; one in a whitelisted ERC-20 stays there. |
| Description & socials | Editable | Off-chain metadata; the creator can update it from the token page. |
| Fee payout address | Editable | The creator can redirect where claimed fees are sent, without changing who controls the token. |
Everything a buyer prices in - supply, fee, routing - is deliberately unchangeable, so what you bought is what you hold. A launchpad where the creator could raise the fee to 3% after you bought would be a different, worse product.
The dev buy
Any ETH you send beyond the launch fee is spent buying your own token inside the launch transaction. Because it is atomic, no sniper can land a buy between your launch and your first purchase - the block in which your token becomes tradable is the block in which you already bought.
- Capped at
2%of supply. The form's presets (25/50/75/Max) are fractions of that cap; a buy that would exceed it makes the whole launch revert rather than silently buying less. - It is a normal curve buy: the standard swap fee applies, and it moves the price like any other buy.
- It is slippage-guarded with a minimum-tokens-out derived from a live quote at submit time.
- It is fully public - the launch event carries the dev-buy amounts, and the token page shows them.
Description, image & socials
Text and images do not belong on-chain, but they should not be forgeable either. The launch transaction commits a hash of your metadata; after the transaction confirms, the app uploads the description, image and links to the API, which verifies them against that hash before accepting. If the upload fails (a dropped connection, say), the app retries and self-heals - your token is never stuck without its identity.
Images are limited to 5 MB and converted to WebP for serving. The creator can edit description and socials later from the token page; name and ticker, as above, never change.
Right after launch
- Your token appears in the live feed within about a second and gets its own page at
/token/<address>. - It starts in the Bonding state: anyone can buy and sell on the curve, price charts work from the first trade, and the page shows a live “% to graduation” meter.
- Your fee share starts accruing from the very first trade - including your own dev buy - and is claimable at any time from the token page.
- If people you referred trade it - or anything else - you also earn the referral rail on their volume.
