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.

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.

Testnet terms of use

Last updated: 2026-10-17

What this site is. testnet.fairhatch.com is a test site. It lets you create a token on FairHatch's testnet-1 contracts on Robinhood Chain Testnet (chain 46630), and buy and sell tokens there, with test ETH. "We" and "us" in these terms mean FairHatch. By using the site you accept these terms. If you do not accept them, do not use the site.

Nothing here has value. Test ETH, WETH (test) and every token created here have no value. FairHatch takes no deposits, offers no way to exchange them for money, and offers nothing here as an investment. Nothing on this site is financial, investment, legal or tax advice.

The contracts are not audited, and their source is not published. The contracts are FairHatch's testnet-1 release. They have not been audited by a security firm, and their source is not yet published. Their code cannot be changed or upgraded: a fault in it stays in testnet-1. WETH (test), which every create, buy and sell uses, is the chain's own contract: others run it and can upgrade it. This site is a testnet only; FairHatch has no contracts on any mainnet.

The site may stop at any time. The testnet, its contracts and this site may be paused, reset or ended at any time, with or without notice, and launches, balances and history may disappear when they are. We may also take the site offline to deal with a fault or a security report.

Your wallet, your transactions. This site holds no key and cannot move anything for you. The page builds each transaction, and your own wallet signs and sends it. A transaction that has been sent cannot be reversed, by you or by us. Check every request your wallet shows you before you approve it. This site asks your wallet for Robinhood Chain Testnet only: never approve a request from it for any other chain.

Use a wallet that holds only test assets. Use a browser-extension wallet on a desktop computer that holds only test assets. Phone wallets are not supported yet.

The rules of every launch created through this site on testnet-1's factory.

  • It charges 0.5% on every buy and 0.5% on every sell while it is on its curve. Of each fee, 50% goes to the launch's creator, 40% to the protocol and 10% to operations. If the trader has bound a referrer in testnet-1's referral registry, then for 180 days after that binding 10% of each curve fee that trader pays comes out of the protocol's part and goes to the referrer; this site binds no referrals. A launch created on testnet-1's factory directly, not through this site, may set its fees up to 2%; the review before you sign shows a launch's own fees.
  • The creator gets no free tokens. A creator who wants tokens buys them.
  • For the first 120 seconds of a launch (FairStart), one buy may take at most 0.5% of the opening curve, and one address at most 1% in all. The creator's first buy, made inside the create transaction, is held to the same 0.5%.
  • A single buy or sell may move the price by at most 5% during FairStart and 10% after it. A large holding may have to be sold in several steps; the page's "Max" offers the most one sell can take at that moment.
  • Creating needs a fresh test price. When FairHatch's testnet price keeper does not run, creating is closed until it runs again; buying and selling go on.
  • A launch graduates when its curve sells out, which takes about 0.32 WETH (test) of buys. Then 20% of the supply and the WETH (test) raised are paired into a Uniswap v4 pool, and the position is minted and held by a vault the launch cannot withdraw from. This site does not trade a launch after it graduates.
  • Holder rewards are not active: testnet-1's factory refuses a launch that asks for them.
  • A creator's share of the fees is held by testnet-1's fee router and can be claimed on chain. This site has no claim button yet.

Creating a token. A token's name and symbol go on chain, in the token itself, and nobody can change or remove them afterwards, including you and us. Do not create a token whose name or symbol:

  • pretends to be, or to be connected with, a real company, stock, brand, person or project;
  • is abusive, hateful, harassing or sexual, or promotes violence or anything unlawful;
  • contains someone else's personal information; or
  • points people to a scam.

The testnet site does not keep pictures, descriptions or links: only the name, the symbol and the supply go on chain.

What we may do. We may hide a launch from this site under our take-down policy. A hidden launch leaves the site's lists and its page shows no name, symbol or picture; selling it is never blocked, and nothing on chain changes. Testnet-1's emergency controller can pause new launches, and in a severe incident new buys; selling can never be paused.

What you may not do. Do not attack, overload or disrupt this site, its servers, or the chain's endpoints and faucets; do not send automated requests at a rate that slows the site for others; do not try to reach data or systems that are not yours; do not use the site to deceive or defraud anyone; and do not move the testnet price feed or pool on purpose, which stops creating for everyone. Security research is welcome under our security disclosure policy, which says what is in scope and how to report.

Others' services. Robinhood Chain Testnet, its RPC endpoint, explorer and faucets, WETH (test), your wallet software, and Cloudflare, which delivers this site, are run by others, not by FairHatch. Their own terms apply to them. No faucet needs your seed phrase or private key: never enter either anywhere.

No warranty. The site and testnet-1's contracts are provided as they are, for testing. We make no promise that they work, are available, are free of faults, or do what you expect.

Limitation of liability. To the extent the law allows, we are not liable for any loss or damage that comes from using, or not being able to use, this site, testnet-1's contracts or any test asset.

Changes to these terms. We may change these terms. The date at the top says when they last changed.

Who we are, and how to reach us. FairHatch runs this site. FairHatch is an independent project, and is not made, run or endorsed by Robinhood. Write to security@fairhatch.com about anything on this site: security problems under the security disclosure policy, launches under the take-down policy, and questions about these terms or the privacy notice. Never send a seed phrase or a private key to anyone, us included.
