Coin press · Robinhood Chain
Bring the blank.
We run the press.
You bring a name, a ticker and an image. The press does the rest — blocks land every tenth of a second on this chain, so the coin is on a curve with real liquidity behind it before you let go of the mouse.
0.015 ETH a strike. Nobody has to approve you first.

Three moves from blank to traded
- 01
Blank
An image, a name, a ticker. Supply is fixed and identical for every coin here, so there is no tokenomics tab to argue over.

Strike
One signature mints the coin and opens the curve. The first buy can land in the very next block, about a tenth of a second later.

Circulate
At $69,420 of market cap the coin graduates on its own. The reserve moves into Uniswap v4, the LP burns, and the hash is on the coin page before the chart catches up.

The whole fee sheet
Five lines, and this is all of them. Gas is ETH, same as mainnet. If a number ever moves, it gets announced a week ahead, and coins already on the curve keep the rate they launched under.

What the contract actually does
Promises are cheap on a launchpad. Every line below is one you can go and read in the source.
The pool burns itself at graduation
The same transaction that moves the reserve into Uniswap sends the LP tokens to the zero address. Nobody holds them afterwards, including us.

The creator queues behind everyone
A creator wallet gets no pre-buy slot and no reserved bag. Its first buy climbs the same curve and pays the same 1% as the hundredth buyer.

One factory, deployed once
No proxy, no admin key. The fee rates sit in an immutable struct, so raising them would mean deploying a new factory at a new address and asking everyone to move.

Creator fees settle per trade
Your 0.4% lands as the trades happen. There is no escrow contract, no claim window and no snapshot to be awake for.

Questions that come up
What stops someone striking a copy of my coin?+–
Nothing, and no launchpad can. Tickers are not unique on any chain. What you get here is a coin page carrying the strike block, the creator wallet and the first ten buys, which settles the argument in about five seconds.
What happens if the curve never fills?+–
It keeps trading on the curve. No deadline, no refund window, and nobody comes along to delist it. Plenty of coins sit at four figures for months and their holders seem fine with that.
Can I change the name or image after striking?+–
The image and the social links, yes, from the creator wallet. The name, the ticker and the supply were written into the token contract at mint, and that is where they stay.
Why is the supply the same for every coin?+–
Because the number is the least interesting thing about a coin, and arguing over it wastes a launch. One supply for everything also keeps the curve maths identical across the press, which is what lets this page quote you a real price before you have struck anything.
Which chain is this?+–
Robinhood Chain, chain id 4663. It is a permissionless Arbitrum Orbit L2 that went to mainnet on 1 July 2026, blocks land about every 100ms, and gas is paid in ETH. Uniswap has been the primary public AMM there since day one, which is where graduated coins end up.
Why not Base or Solana?+–
Because 100ms blocks change how a bonding curve feels. On a two-second chain the race for the first buy goes to whoever pays the most gas. Here the queue moves fast enough that it goes to whoever clicked first.
