How to launch a coin
Never done this before? Start here. Once your wallet has ETH the whole thing takes about a minute.
- 01
Get a wallet
Any Ethereum wallet works. MetaMask, Rabby and Phantom are the usual ones.
- Install the extension and write the seed phrase down on paper. Nobody from Touchstone will ever ask you for it.
- Add Robinhood Chain as a network. The Settings page lists the chain ID and the RPC this instance is pointed at.
- Your wallet is the account. There is no sign-up here, no email, no password.
- 02
Put ETH in it
You need three things covered, and they are all ETH on Robinhood Chain.
- Initial liquidity
- 0.1 ETH
- Creation fee
- 0.001 ETH
- Gas
- 0.0002 ETH
Stays in the pool as your buy side. Locked, not spent.
What the launchpad charges. This one you do spend.
An L2, so cents. Varies with the network.
0.1012 ETH leaves your wallet, and 0.1 of it is still yours — locked in the vault as your token’s liquidity, not spent. Only the fee and the gas are gone.
- Bridge ETH to Robinhood Chain first. ETH on mainnet Ethereum cannot pay for anything here.
- Almost everything you send is your own liquidity, and it stays yours — locked in the vault, not spent.

Step 1 — Identity
What people see: the name, the ticker, the logo and the links.
- Name and ticker are written into the contract and cannot be changed afterwards. Read them twice.
- The logo is cropped to 256×256 and shows up on the token page, the Report Card and the explorer.
- The description is two sentences at most. It is what a buyer reads before deciding.
- Links are optional, but a token with no X and no Telegram looks like it was abandoned at birth.
- 04
Step 2 — Mechanics
The numbers that get burned into the contract. Start by picking a template.
Fair launch
You keep nothing.
100% to liquiditynothing to you- The whole supply goes to liquidity.
- The most trustworthy thing you can ship.
- You earn from the trading tax, not from a bag.
Creator vesting
You keep a share, on a schedule.
95% to liquidity5% vesting- Up to 20% of supply, vesting linearly on-chain.
- You cannot sell it early and you cannot revoke the schedule.
- The token page shows the split and the unlock date to everyone.
- Buy and sell tax are capped at 5% by the bytecode. You can pick less; you cannot pick more, and there is no setter to raise it later.
- The LP lock is a minimum of one day and you can extend it afterwards, never shorten it. Longer reads better to buyers, and that is the whole point.
- Total supply is minted once. There is no mint function anywhere in the contract.
- 05
Step 3 — Review and sign
One signature. Everything above becomes immutable in that block.
- 01
Token deployed
Supply minted once, in `initialize`
- 02
Ownership → 0x0
No function exists to take it back
- 03
Tokens + ETH to the vault
The only exit is the DEX pair
- 04
Page and kit ready
Report Card, copy kit, public URL
- The review screen shows the exact parameters and the exact cost. Nothing is hidden behind it.
- Anything you overpay comes back in the same transaction.
- When it lands you get the token page, the Report Card and the copy kit, already made.
- 01
- 06
Open the market
Seeding the liquidity is what makes the token buyable.
- Hit “seed liquidity” on the token page. Anyone can call it — it only ever sends the locked tokens and ETH to the DEX pair.
- From that moment the pair is live and people can buy and sell from the page itself.
- The LP tokens go straight back into the vault, locked for the term you chose.
Before you sign, know this
- None of it can be undone
- Ownership is renounced in the creation block. Supply, taxes, name and ticker have no setters. If you get a number wrong, the only fix is launching again.
- The liquidity is yours, but not yet
- The ETH you seed stays in the pool and the LP sits in a timelocked vault. You get it back when the lock expires, and you can extend the lock at any time — never shorten it.
- The price comes from the pool, not from us
- It is a constant-product AMM: price is the ratio between the reserves. Every buy pushes it up, every sell pushes it down. There is no order book and nobody market-making behind it.
- A launchpad cannot make your coin work
- Touchstone guarantees the contract cannot rug you. It guarantees nothing about whether anyone buys. That part is still the hard part.
