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 in a Uniswap v4 pool with real liquidity behind it before you let go of the mouse.
Gas is the whole cost of a strike. Nobody has to approve you first.

The strike ledger
reading Robinhood Chain…
Every coin off the press, numbered in the order it was struck. Market cap is the pool price times the full supply; volume is the ETH that changed hands in the last 24 hours.
| No. | Coin | Struck | Market cap | 24h volume | 1h |

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.
about 30 seconds of typing
- 02
Strike
One signature mints the coin and opens its Uniswap v4 pool in the same transaction. There is no curve to climb and nothing to graduate out of.
gas only
- 03
Circulate
It is tradable in the block it was struck in. 79% of supply is already sitting in the pool as liquidity nobody can withdraw, and the hash is on the coin page before the chart catches up.
immediate, no button to press
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 already struck keep the rates they launched under.
| Strike a cointhe press charges nothing to mint | gas only |
| Buy or sellsplit 5% creator / 5% protocol, always in ETH | 10% |
| Opening valuationwhere the pool starts, fixed for every coin | 1.7 ETH |
| Listing the coinevery struck coin gets a page | nothing |
| Withdrawing creator feespushed to you as the trades happen | nothing |
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 liquidity has no way out
The press owns the pool position and was written without a function that removes it. Not locked, not timelocked — the code to take it back simply does not exist, for the creator or for us.
PlanchetPress.sol — no removal path
The creator is handed nothing
No pre-buy slot, no reserved bag, no vesting schedule. A creator holds zero of their own coin and is paid out of trading instead, 5% of every buy and sell, in ETH.
balanceOf(creator) == 0 at the strike block
One factory, deployed once
No proxy, no admin key. Every rate is a Solidity constant, so raising one would mean deploying a new press at a new address and asking everyone to move.

Creator fees settle per trade
Your 5% is pushed to your wallet 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 nobody buys it?+–
It keeps trading in its pool. 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 opening price identical across the press, which is what lets this page quote you a real valuation 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 every struck coin opens.
Why not Base or Solana?+–
Because 100ms blocks change how the first minute 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.
