Testnet This is a test site on Robinhood Chain Testnet (chain 46630). It runs on test ETH, and nothing here has any value.

Phone wallets are not supported yet: creating and trading need a desktop browser with a wallet extension.

What testnet means
  • Test ETH, WETH (test) and every token created here have no value. FairHatch offers no way to exchange them for money, and nothing here is an offer or an investment.
  • The contracts are FairHatch's testnet-1 release. They have not been audited by a security firm, and their source is not yet published.
  • Each launch opens at a price taken from a test price feed and pool that FairHatch runs on this testnet, not from any real market. FairHatch's price keeper is there to keep that price fresh and near a set value; when the keeper does not run, the price goes stale and creating is closed until it runs again, while buying and selling go on. Testnet shows how the mechanism works, not what anything is worth.
  • The testnet, its contracts and this site may be paused or reset at any time, and launches, balances and history may disappear when they are.
  • Use a browser-extension wallet that holds only test assets. This site asks your wallet for Robinhood Chain Testnet only; never approve a request for any other chain.
  • Phone wallets are not supported yet: use a desktop browser with a wallet extension.
  • A launch graduates when its curve sells out, which takes about 0.32 WETH (test) of buys at the testnet price. This site does not trade a launch after it graduates.

Faucets are run by others, not by FairHatch. No faucet needs your seed phrase or private key: never enter either anywhere.

Names are the tokens' own, and two tokens can share one. The address identifies a token; one not yet named is listed by its address.

Connect a wallet

Looking for a wallet in this browser…

Connecting tells this page which address you control, and the address stays in the browser. Nothing is sent until you press a create, buy, sell, unwrap or clear-approval button and approve the request in your wallet, on Robinhood Chain Testnet only. Use a wallet that holds only test assets.

Create a token

One transaction mints the supply, opens the curve and buys your first tokens. You get no free allocation — you buy at the same opening price as everyone else — and you earn 50% of every trade fee for as long as it trades. Fees.

No creator allocationLiquidity locks at graduation

Name and symbol

Both go on chain, in the token itself. With the total supply below, they are the only part of what you write here that the contract carries.

Total supply

Any whole number of tokens from 1 000 000 to 1 000 000 000 000, the range the factory accepts. Commas or underscores between groups of three are fine.

Supply changes how many tokens there are and the price of each, not what the whole launch is worth or what it takes to graduate. Every launch opens at the same valuation, so one token opens at that valuation divided by the supply.

The creator is the address that sends the create: connect a wallet from the header to create from it.

On this site both trade fees are fixed at 0.5%, the buy fee and the sell fee alike. testnet-1's factory accepts up to 2% from a create sent to it directly, so check the fee of a launch created elsewhere. Nothing else on this list is configurable, by you or by us: the factory refuses a launch whose configuration does not repeat its own policy exactly.

No creator allocationLiquidity locks

One transaction

1The token is deployed from one template
2The curve opens at a price read from the chain
3Your first buy runs, at that opening price

All three are one call. The factory is payable: the value you send is wrapped to WETH (test) inside it, approved to the curve and spent on your buy in the same transaction, so there is no window between the launch opening and your purchase for anyone else to act in. Send nothing and the launch still opens; you simply have no position in it.

The opening price is not chosen by you. On testnet-1 it comes from a test price feed and pool that FairHatch runs on this testnet, which FairHatch's price keeper is there to keep fresh and near a set price. The factory reads it during the create call and refuses the create if that reading is stale or out of band, so when the keeper does not run, creating is closed until it runs again, and this page says so.

What is not here

The buy and sell fees are not chosen here: on testnet-1 this site sets both, and the review before you sign shows them. The testnet site keeps no picture, description or links: only the name, the symbol and the supply go on chain. What is live.
