A memecoin with stock for a keel.
Launch a coin whose whole market is held in one real tokenized stock: NVDA, TSLA, SPY, any of 96. Every buy turns your ETH into the stock in the same transaction and pays it in. Every sell pays you back out of it, in the stock or in ETH. Nothing sits in ETH, and nothing leaves for a platform.
Pick a stock. Pick a start.
Everything on the right is live: the stock’s price in its Uniswap pool right now, and what a first buy would get on a fresh coin.
A coin started at $3,000 has $3,000 of the stock behind its curve before anyone buys. Buying the first 10% of its supply takes about $337 of the stock; the first half, about $3,030.
The coin floats. The stock holds it up.
A Keel coin is its own market, and that market keeps nothing but one stock. That is the whole idea.
Pick the stock
Name the coin, give it a picture, and choose the stock its market is held in. Any of 96 tokenized stocks on Robinhood Chain with a live Uniswap pool.
Set where it starts
Choose a starting value: $1,000 to $30,000 of the stock sits behind the curve before anyone buys. A smaller start moves faster; a bigger one moves slower.
Every buy buys stock
Pay in ETH, USDG or the stock itself. Your ETH is swapped through Uniswap into the stock inside your transaction, and every share goes into the coin’s market.
Every sell pays stock
Sell and the market pays you in shares, or swaps them back to ETH or USDG on the way out. The market can always pay: it holds the stock for every coin it sold.

All of it, in the stock. 1% is the fee: half stays in the market, half goes to the coin’s creator.
of a fresh coin started at $3,000, priced in shares, not in ETH.
Always fully held
The market keeps every share buyers paid in, less what sellers took out. Selling every coin back can never ask for more than it holds: that is how a constant-product curve works, and it was tested trade by trade.
Rides the stock
A coin is priced in shares. If NVDA rises 5%, every NVDA coin’s dollar price and every seller’s payout rise 5% with it, before anyone trades.
Exit in the stock
Sell straight into shares, with no swap and no Uniswap cost at all. Or take ETH or USDG; the swap happens in the same transaction.
Nothing to pull
No owner, no admin key, no upgrade, no pause. The fee is fixed at 1% for every coin. Nothing in a coin can be changed after launch, by anyone.
The creator earns stock
Half of the fee, 0.5% of every trade, builds up for the coin’s creator in the stock. Anyone can press Claim; it always pays the creator.
Its picture lives on chain
Up to 24 KB of picture, description and links are stored as contract code with the coin. There is no server to go dark.
What a coin can be.
| Ordinary launchpad coin | Coin with a stock treasury | Keel coin | |
|---|---|---|---|
| What its market holds | ETH | ETH, plus stock bought with a fee | Only the stock, every share of it |
| How much of a buy buys stock | None | The fee, 1–10% | All of it |
| If the stock rises | Nothing changes | The treasury is worth more | The coin’s price and every payout rise with it |
| How you leave | Sell for ETH | Sell for ETH, or burn for a share | Sell for the stock itself, ETH or USDG |
| Where trading fees go | The platform | The treasury | Half to the market, half to the creator, in stock |
| Who can change it | Often the platform | Nobody | Nobody |
Asked, answered.
What is a Keel coin?
A coin that is its own market, and whose market holds one tokenized stock instead of ETH. Its price is a number of shares. Buying pays shares in; selling takes shares out. The coin is an ordinary ERC-20, so it moves between wallets like any token.
Do I need to own the stock to buy?
No. Pay in ETH and the coin swaps it into the stock through Uniswap inside your transaction (ETH → USDG → the stock). You can also pay in USDG, or in the stock itself if you hold it, which skips the swap.
What do I get when I sell?
Shares of the stock, straight out of the market. Or choose ETH or USDG, and the shares are swapped on the way out in the same transaction. Your price limit covers the whole route, so a swap that would pay less than you accepted is refused and nothing moves.
Why would the price go up?
Two ways. Buyers move it along the curve, as on any launchpad. And because the price is in shares, the stock’s own moves carry through: if the stock goes up, the coin is worth more dollars with nobody trading.
Can the market run out of stock?
No. It is a constant-product curve with a virtual starting reserve. Selling every coin back walks the price down to where it started, and that takes exactly the real shares in the market, minus what the fees left there. The contract also caps any sale at the shares it holds, and the tests drive random buyers and sellers and then sell everything back.
Where does the 1% fee go?
It is taken in the stock on every buy and sell. Half stays in the market, which nudges the price up for everyone holding. Half builds up for the coin’s creator, who can claim it in the stock at any time, or hand it to another address. None of it goes to Keel.
What does it cost to launch?
Only Robinhood Chain gas, a few cents. You can add a first buy in the same transaction so nobody gets in before you. The very first launch also deploys the factory: one more transaction, which anyone can send, to an address fixed by its code.
Is this audited or risk-free?
No. It is unaudited, experimental software, tested against live chain state by the properties described in the docs. Coins can lose almost all their value, stocks can fall, and Robinhood can pause a stock token, which would pause every coin held in it. Only use money you can afford to lose.
Launch one. Give it a keel.
Pick a stock and a starting value. Every buy after that buys the stock.
