Frequently asked questions
Short, exact answers about the one-ticker rule, launching, quiet coins and fees. For the full mechanics see How it works.
The one-ticker rule
What is a vamp token?
A copy of a token, launched under the same ticker and usually the same name and picture, to catch buyers who pick the wrong contract. On open launchpads a trending ticker is often copied many times within minutes.
How does OneBlock stop vamps?
Every ticker maps to one live coin in the launchpad contract. A launch that asks for a ticker that already has a live coin is refused by the contract with the error "ticker already launched". Because the check is in the contract and not on this website, it applies to every app, script or bot that launches through OneBlock.
Does this stop copies on other launchpads?
No. Anyone can still deploy a token with any ticker elsewhere, directly on the chain or on another launchpad. OneBlock guarantees that on OneBlock there is exactly one live coin per ticker.
Which spellings count as the same ticker?
Case doesn't matter, only the letters A to Z and the digits 0 to 9 are allowed, and 0 and 1 count as O and I. So DOGE, doge, Doge and D0GE are one ticker, while DOGE2 is a different one. Look-alike letters from other alphabets and hidden characters are refused.
How do I check if a ticker is free?
Type it into the box at the top of the home page. The answer comes straight from the contract: free, claimed, quiet (it will free up if nothing changes) or available again.
Does claiming a ticker give me rights to the name?
No. A ticker on OneBlock is a slot in a smart contract, not a trademark or any other legal right. Launching a coin under someone else's brand can still break the law and our Terms.
Launching
Why does a launch take two transactions?
The first stores a sealed commitment that hides your ticker. At least 5 seconds later the second reveals it and creates the coin. A bot watching pending transactions only sees your ticker in the second step, and by then it can't launch it before you. The app runs both steps and the wait for you; you confirm twice in your wallet.
What if I close the page between the two steps?
Your reservation stays valid for 24 hours. Open OneBlock again in the same browser with the same wallet and the app offers to finish the launch.
What does launching cost?
A launch fee that depends on the ticker length (0.0005 ETH for 5 to 10 characters, 0.001 for 4 and 0.005 for 1 to 3 on Robinhood Chain; 1, 2 and 10 USDC on Arc), plus network gas for the two transactions. If you make a first buy, that amount goes into the curve and you receive tokens for it.
Why do short tickers cost more?
Short tickers are the most valuable and the most likely to be grabbed in bulk. A higher fee makes that expensive without affecting normal launches.
Where is the image stored?
Inside the token contract, on-chain. The app shrinks it to a small square image first so it stays cheap to store.
Quiet coins and retired coins
Can someone hold a ticker forever without using it?
Only by keeping real liquidity in the coin. A coin with less than 0.1 ETH on Robinhood Chain (250 USDC on Arc) of liquidity for 7 days loses its ticker to the next launch that claims it. Short buy-and-sell round trips, including flash loans, don't reset that clock: the liquidity has to stay for 24 hours to count.
What happens to a coin whose ticker is taken over?
It is retired. Nobody can buy it any more, but everyone holding it can still sell it back to the curve at any time. The board shows it as retired and lists the new coin under the ticker.
Can a popular coin lose its ticker?
Not while it has real liquidity. A coin at or above 0.1 ETH on Robinhood Chain (250 USDC on Arc) keeps its ticker with no time limit. If it drops below that, it keeps the ticker for another 7 days, and any real recovery in that time resets the clock.
Trading, fees and safety
How is the price set?
By a constant-product bonding curve. Buying pushes the price up and selling brings it down. There is no order book and no one else's liquidity to wait for.
What are the trading fees?
1% on every buy and sell. 30% of it goes to the coin's creator and 70% to the OneBlock treasury.
Is there a presale or a team allocation?
No. The full supply of every coin starts on the curve. The only way to get tokens is to buy them, including for the creator.
Can the creator mint more tokens or freeze my tokens?
No. The token has no owner and no mint, freeze, blacklist, pause or transfer-tax function. What the creator can do is sell the tokens they bought, like anyone else.
Does OneBlock hold my funds?
No. OneBlock is non-custodial. Every action is a transaction you sign in your own wallet, executed directly by the public contracts.
Is OneBlock audited?
The contracts have not been audited by a third-party firm. The ticker rules are covered by an automated test suite, but that is not an audit. Only use amounts you can afford to lose.
Which wallets and networks work?
Any EVM wallet that can add a custom network, such as MetaMask or Rabby, on Robinhood Chain (chain ID 4663) and Arc (chain ID 5042). The app adds the network to your wallet if needed.
