Launch your first coin
From an empty wallet to a live pool. Six fields and one signature, but a few of those fields are permanent, so it is worth understanding all of them before you sign.
What you need first
| A wallet | MetaMask, Rabby, or anything else that injects a provider. Mobile works through an in-app browser. |
|---|---|
| ETH on Robinhood Chain | Gas plus your liquidity. Budget at least 0.02 ETH to be comfortable. |
| A recipient address | The wallet that will receive the fee share. It can be yours. |
| An image, optionally | Picked off your computer. It is cropped and shrunk in the browser and written into the token contract. |
Getting ETH onto the chain
Robinhood Chain is an Arbitrum Orbit rollup, so the canonical route is the Arbitrum bridge. Deposits take around ten minutes. Third party bridges such as Relay, Across, LiFi and Stargate are usually faster and cost a little more. Gas is paid in ETH, there is no separate chain token to acquire.
Check the network before anything else
The six fields
- 1Name and tickerUp to 64 and 16 characters. Both are written into the token contract at construction and can never be edited, so check the spelling twice.
- 2SupplyA whole number, minted once. All of it goes into the pool, so this number and your ETH together set the opening price. A billion is the common choice and there is nothing magic about it.
- 3The wallet that receives feesAny address. It never has to connect to this site, it never has to be a wallet you control, and it can be a contract as long as something can eventually claim from it. This is permanent.
- 4Fee on the ETH legBetween 0.01% and 2%. This is what every swap in your pool pays on the ETH side. Higher means more revenue per trade and worse prices for traders, which usually means fewer trades.
- 5Share to that walletHow much of the fee goes to the address above. The remainder funds the platform. Also permanent.
- 6ETH into the poolMinimum 0.005. This becomes the pool's liquidity and you cannot take it back. Thin liquidity means violent price moves on small buys, which cuts both ways.
Signing
The panel on the right of the form totals what you are about to send: your liquidity plus the launch fee if one is set. Everything under it is what gets frozen into the pool. When you press launch, your wallet asks you to confirm one transaction. There is no second step and no approval beforehand, because you are not moving a token you already own.
When it lands you get the coin page, and the pool is already tradable. Trading is live in the same transaction that creates it, which is worth knowing: see security on snipers.
Afterwards
Fees accrue as soon as people trade. They are not sent to you automatically. Go to claim fees, connect the wallet you nominated, and withdraw whenever you like. Gas on this chain is cheap enough that claiming often costs almost nothing.
