Beta tester guide

Launch a token, trade it, and try to break it — on a test network, with tokens that have no real value. It takes about ten minutes, and all you need is a browser wallet.

Two chains, and how they differ

You can launch on either. They are not the same test twice — the money is different, and so is what a pool can be paired against. If you only have time for one, do Robinhood first; if you have time for both, the interesting bugs live in the differences.

Network details

The faucets can add these to your wallet for you. Enter them by hand only if you need to.

Getting set up

1. Add a network to your wallet

   Most wallets do this for you — you can probably skip this step.Hit Connect on runitup.gg and MetaMask offers to add the network itself, for whichever chain the thing you are looking at is on. Approve it and the network is in your wallet, with nothing typed in by hand. Any wallet that supports the same prompt behaves this way.

   If your wallet does not offer, add it from the faucet instead: the Robinhood Chain testnet faucet has an Add testnet button, and Circle's faucet offers the same for Arc. Either way your wallet asks you to approve a new network — that is expected, and it is the same detail listed above.

   Any EVM browser wallet works: MetaMask, Rabby and Coinbase Wallet have all been used against this build.

2. Claim testnet funds

   On Robinhood Chain

   On the faucet, paste your wallet address and click Send tokens. One claim gives you:

   Asset	Amount	What it is for
   ETH	0.01	Gas, launch fees and buying
   TSLA	5	Pairing a token against a tokenized stock
   AMZN	5	Pairing a token against a tokenized stock
   PLTR	5	Pairing a token against a tokenized stock
   NFLX	5	Pairing a token against a tokenized stock
   AMD	5	Pairing a token against a tokenized stock

   You can claim once every 24 hours, so treat the 0.01 ETH as your budget for the day.

   Click Import all on the faucet to make the stock tokens visible in your wallet. That is cosmetic — they are already yours either way.

   On Arc

   Open Circle's faucet, choose Arc Testnet from the network list, paste your address and claim. It sends 20 USDC, and you can claim again every 2 hours.

   That one balance is everything on Arc — gas, the launch fee and whatever you buy with. There are no stock tokens to claim here, because Arc has no venue that can pair against them.

3. Connect to Runitup

   Head to runitup.gg and hit Connect. If your wallet is on the wrong network for what you are doing, the site will ask you to switch — a token lives on one chain, and trading it means being on that chain.

4. Launch a token

   Open Launch token and work down the form:

   • Name, ticker, image — anything you like.
   • Chain — Robinhood and Arc are both live. Base, Ethereum, BNB and Tempo are marked coming soon on purpose. Picking a chain changes what the rest of the form offers you, so pick it first.
   • AMM venue — Uniswap V3 or SushiSwap V3 on either chain, plus Uniswap V4 on Robinhood. They all seed the pool the same way. Pick Uniswap V4 to pair against a stock; it is the only venue that can, which is also why Arc cannot.
   • Pair with — what your token trades against for the rest of its life. On Robinhood: ETH, or one of the stocks you claimed. On Arc: USDC, the chain's own money.
   • Dev buy — optional. Buys your own token inside the launch transaction, so nothing can trade ahead of you.

   What it costs	Robinhood	Arc
   Launch fee	0.0005 ETH	0.0005 USDC
   Starting market cap	$2,700	$2,700
   Supply range	1 – 10,000,000,000	1 – 10,000,000,000
   Trading fee, and your share	1% per trade — you keep 75%	1% per trade — you keep 75%

   Your whole supply goes into a real pool with permanently locked liquidity. No bonding curve, no unlock — that is the part worth testing.

5. Trade it

   Open your token's page, or use the swap page to trade anything that has launched. Buy, sell, watch the chart move, then confirm the trade shows up on that chain's explorer — Robinhood's or Arcscan.

   If you paired against a stock you do not hold, the swap routes you there through ETH — you should not need the stock in your wallet to buy.

What we want you to try

Anything helps, but these areas changed most recently:

• Launch the same token twice, once on each chain, and compare the two pages. Anything that reads differently for reasons other than the money is a bug.
• Check that an Arc token's figures are in dollars everywhere — the token page, the explorer, Trending, your portfolio — and never quietly in ETH.
• Launch on each venue the chain offers and see whether anything differs that should not.
• Launch paired against a tokenized stock on Robinhood, then check the price and market cap read sensibly in dollars.
• Use a dev buy and confirm the projected starting market cap matches what you actually get.
• Trade from a wallet holding only ETH and buy a stock-paired token.
• Switch chains mid-flow — start a trade on one, change network in your wallet, and see whether the site keeps up or gets stuck.
• Do all of it on a phone. Mobile is where most recent bugs turned up.

Worth reporting

• Any number that looks wrong — prices, market caps, fees.
• Anything in the wrong unit: a value labelled ETH that is really a stock, a dollar figure on an Arc token that is really USDC counted wrong, or the reverse.
• A link that opens the wrong chain's explorer.
• Buttons or icons that appear to do nothing.
• Transactions that fail without telling you why.

Known limits during beta

• 0.01 ETH a day is not much. A launch costs 0.0005 ETH plus gas, leaving room for several launches and plenty of trades — but if you run dry you wait for the next claim. Arc is the easier one to keep testing on: 20 USDC every two hours goes a long way against a fee of 0.0005.
• Arc has no Uniswap V4, so no tokenized-stock pairs there. Every Arc pool is quoted in USDC. That is a property of the chain, not something switched off.
• Arc mainnet is not out yet. It is announced for 16 September 2026, and only the testnet exists to launch against today.
• Testnet data can reset. Nothing you launch on either chain carries over to mainnet.
• Some chains and venues are visibly disabled. Base, Ethereum, BNB and Tempo read “coming soon” by design, not because they are broken.

Contract addresses

Only needed to add a token to your wallet by hand, or to read the contracts yourself.

Robinhood Chain tokens

Arc tokens

That address is a precompile — the chain's own money seen through an ERC-20 view. You should not need to add it by hand; your wallet already shows the balance as the network currency.

If something goes wrong

• Wallet will not switch networks. Check the chain ID: 46630 for Robinhood, 5042002 for Arc. Remove the network and re-add it from the faucet.
• The site says you are on the wrong network. A token lives on one chain. Trading it means being on that chain — the switch prompt is the site telling you which, not a failure.
• “Insufficient funds” while showing a balance. Note what the site says you need against what you hold, and which asset each is in — that mismatch is exactly the sort of bug worth reporting. On Arc, remember the balance paying for gas is the same USDC balance you are trying to spend.
• A transaction fails with no message. Copy the transaction hash, look it up on Robinhood's explorer or Arcscan, and send the link.
• Stock tokens missing from your wallet. They are still there. Use Import all on the faucet, or add the address by hand from the table above.
