Make your own coin on Robinhood. One click, one transaction, done.

Founder lets anyone launch a coin on Robinhood in a single transaction. Every launch creates a standard ERC-20 token, deposits its whole supply as permanent liquidity in a Uniswap v4 pool paired against ETH, and makes trading available immediately.

01

The Launch

Every launch is executed in a single on-chain transaction.

In that one transaction, the factory does everything needed to make your coin tradable:

1
Deploy the coin
A standard ERC-20 with no owner and no mint function. Its whole supply is minted once, inside this transaction.
2
Create the pool
A new Uniswap v4 pool pairing the coin against ETH, with no hook contract attached to it. Its price opens at a fixed fully diluted valuation (FDV).
3
Add liquidity
The entire supply is deposited as a single-sided liquidity position, handed straight to the locker.
Once the transaction is confirmed, trading is live.

There are no additional deployment steps, listings, or manual configuration. Anything you send above the launch fee buys your own coin at the opening price in that same transaction, and whatever the pool does not take is refunded to you.

02

What “locked liquidity” means, and why it matters

Liquidity is the pool of money that lets people buy and sell your coin. If someone drains that pool, the coin becomes worthless instantly and holders can’t sell. In crypto this is called a rug pull, and it’s the most common way people lose money on new coins.

Founder makes it impossible.

The liquidity is held by Founder’s LP Locker contract, and that contract was written without any way to take it back out. There’s no withdraw button, no unlock date, no “transfer to another wallet” option.

That applies to everyone equally:

The creator can’t remove it
Founder can’t remove it
No one can remove it

This isn’t a promise we’re making. It’s a fact you can verify yourself by reading the contract on a block explorer.

There is no bonding curve and no migration step. The locked position covers a price range, and the pool opens on the edge of it where the position holds only the coin and none of the ETH — which is how the entire supply goes in without anyone putting up ETH alongside it. Buying pushes ETH into the position and moves the price through the range; selling moves it back.

The locker adds that liquidity once, at launch, and after that only ever pokes the position to settle earned fees. Since no withdrawal path exists in the contract, liquidity cannot be rugged or reclaimed.

Only the locker’s own position is locked. Anyone is free to add their own liquidity to the same pool, and whoever adds it can take it back out again.

03

How creators earn

Every time someone buys or sells your coin, the pool takes a fee out of the trade.

1% pool feesplit on every buy & sell

Your share accrues to the locked position as it is traded, and you can claim it whenever you want. Fees build up in both currencies — buys leave ETH behind and sells leave coins — so one claim can pay out both.

The more your coin gets traded, the more you earn — there’s no cap and no end date.

The creator fee wallet defaults to the wallet that launched the coin, and can later be updated by its current owner. Claiming is permissionless, but a claim can only pay the wallet on record — so a stranger cranking it just saves you the gas.
A launch also costs one fee, paid once in ETH by whoever launches. The create form quotes it before you confirm, and the factory refuses a launch fee above 0.1 ETH.
The contracts bound both trading fees: a pool fee can never exceed 1% and is written into the pool when the pool is created, and the protocol’s share of what accrues can never exceed half. Both are fixed onto a coin at launch, so changing either one later never re-prices a coin that already exists.
04

Graduation

Graduation is a milestone — not a migration.

✓ GRADUATED

A coin is graduated while the ETH sitting in its locked position is at or above the graduation threshold its launch configuration carries. The badge and the progress bar you see throughout Founder are that same reading.

It is a live reading, not an event. Nothing is emitted and nothing is triggered when the line is crossed, and the status goes back to not graduated if selling pulls the position’s ETH under the threshold again.

Nothing else changes.
Liquidity stays locked.
Trading continues normally.
No contracts change.
05

Buying & selling

You can trade directly on Founder.

Open a coin and use its trade panel. Buying spends ETH; selling returns ETH.

  • Every trade is your own wallet’s transaction, executed by Uniswap’s Universal Router.
  • A buy is one transaction. A sell adds a one-time Permit2 approval of the coin and a signature authorising the router.
  • Slippage tolerance starts at 1% and can be changed on the panel. Every swap carries a minimum output and a 5-minute deadline, so it reverts rather than filling worse than you accepted.
Your funds stay yours
Founder never holds your money — every swap runs from your own wallet straight through the pool.

Trading and launching need a connected wallet, and nothing more — there is no account and no sign-in. Browsing the board, a coin, its chart, trades and holders needs not even that.

You need ETH on Robinhood for the trade and for gas. If your funds are on another chain, bring them across with the bridge, which works on a connected wallet alone.

Since every launch creates an ordinary Uniswap v4 pool with no hook attached, coins can also be traded through any compatible v4 interface or aggregator on Robinhood.

Creator earnings
At least half of every pool fee, for as long as the coin trades
Trading
An ordinary Uniswap v4 pool with no hook — tradable anywhere on Robinhood
Simple to launch.
Simple to verify.
Built to last.
