How it works
One transaction on Base or Robinhood Chain. Gas is the only cost — usually a few cents.
What a launch does
- 1Deploys your token
A plain ERC-20 with EIP-2612 permit. Fixed supply of 1,000,000,000. No mint, no pause, no blacklist, no transfer tax, no owner.
- 2Opens a Uniswap v4 pool
ETH / your token (or USDG / your token on Robinhood Chain), no hook. The pool starts at the market cap you pick.
- 3Locks 100% of supply as liquidity
The whole supply goes into one single-sided position. Its NFT is minted to an ownerless locker that has no function to withdraw, transfer or shrink it. Ever.
- 4Registers the fee routing
The trading fee you chose (0%, 1% or 3%) goes 100% to the beneficiaries you named, or is burned if you named none. Fixed at launch, unchangeable.
Trading fees, in plain words
0% — a feeless pool. Trades cost only Uniswap gas. Nobody earns from volume, including the creator.
1% or 3% — Uniswap charges it on every trade and it accrues to the locked position. Anyone can press Collect on the token page: the accrued fees leave the pool and are paid straight to the beneficiaries in that same transaction (or burned to 0x…dEaD if the launch has no beneficiary). If a beneficiary cannot receive the payment, their share is credited to them and can be claimed any time; it is never lost and never blocks the others.
Beneficiaries and shares are set at launch and can never be changed — a promise like “half the fees go to this address” is enforced by the contract, not by us.
What can never happen
- No platform fee
There is no fee address, fee variable or treasury anywhere in the factory or the locker. Nothing to switch on later — it cannot be added to immutable code.
- No rug
Nobody can remove liquidity: not the creator, not us. Collecting fees removes zero liquidity.
- No pre-mine
Every token starts inside the pool. The only way to hold any is to buy.
- No admin
No owner, no pause, no upgrade, no allowlist. The contracts are the same for everyone, forever.
What you should know
Price follows a single-sided Uniswap v4 curve: the first buyers get the most tokens per ETH, and every buy moves the price up. Sells move it down. There is no anti-snipe mechanism; bots can buy in the first block like anyone else.
Nothing is refundable and nothing can be edited after launch — not the name, not the fee, not the beneficiaries. Metadata (image, description, links) is stored by this site and can change; the token itself cannot.
Tokens launched here are created by their launchers, not by openlaunch. Do your own research; a locked pool does not make a token valuable.
