Every trade buys stock. Then it flies.
Launch a coin whose fee on every trade buys a real tokenized stock, held by the coin itself. When its curve sells out, the coin fledges: its ETH and coins become a Uniswap pool that nobody can ever pull, and that pool’s fees keep buying the stock.
Born on a curve. Grown on stock.
A Fledge coin has two lives. On its curve, every trade feeds its nest with stock. Once the curve sells out, it moves into Uniswap for good and keeps feeding the nest from there.
Pick what it buys
Name the coin, give it a picture, and choose its stock: NVDA, TSLA, SPY or any of 96 tokenized stocks on Robinhood Chain.
Set the fee, once
Anything from 0.25% to 10% of every curve trade. It is written into the coin at launch. Nobody can change it afterwards, including you and us.
Fill the curve
800 million coins sell on the coin’s own curve. Each trade swaps its fee into the stock on Uniswap in the same transaction. The bar shows how close it is to fledging.
Fledge
The buy that takes the last curve coin moves the 3 ETH raised, plus 200 million coins, into a Uniswap pool at exactly the curve’s last price. That liquidity is locked for good.
Closest to fledging.
Before and after.
The nest is the same contract all the way through. Only where the coin trades changes.
A market inside the coin
- Trades
- On the coin’s own constant-product curve, from the first block. There is nowhere else to trade it, so no trade skips the fee.
- Fee
- The launcher’s choice, 0.25%–10%, taken in ETH on buys and sells.
- Fee goes
- Into the stock, inside the same transaction, at a fair price.
- Ends
- When the last of the 800 million curve coins is bought.
A pool nobody can pull
- Trades
- In the coin’s 1% Uniswap v3 pool: any wallet, any aggregator, any router.
- Liquidity
- A full-range position owned by the coin contract, which has no function that can remove it.
- Fee goes
- The position’s fees paid in ETH buy the stock. The fees paid in the coin are burned.
- Harvest
- Anyone can press it; every redeem does it automatically.
Fees usually leave. Here they stay.
Follow one trade on the curve. The numbers below are live: today’s ETH price, and today’s NVDA price in the pool the nest buys from.

No gap to snipe
The pool opens at exactly the price the curve ended on, to the wei. There is no jump between the curve and Uniswap for a bot to take.
Nobody gets into the pool first
Until the coin fledges, its pool refuses the coin. If someone sets a price there anyway, fledging moves it back, and that can only cost them.
Liquidity nobody can pull
The position belongs to the coin contract, which has no owner and no function that removes liquidity. There is no rug to pull.
Never overpays
The nest checks both pools’ 30-minute average price before it buys. If a pool has been pushed, the purchase waits instead of overpaying.
Exit into the stock
Burn coins for exactly that share of the nest, in the stock itself. It works before and after fledging.
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 memecoin | Treasury coin on a curve | Fledge coin | |
|---|---|---|---|
| What the coin owns | Nothing | A stock position | A stock position that keeps growing after launch |
| Where it trades later | Wherever the creator put liquidity | Only its own curve, forever | Uniswap, like any token |
| Who can pull liquidity | Often the creator | Nobody | Nobody. The coin owns it. |
| Where trading fees go | The platform or creator | The treasury | The nest, on the curve and in the pool |
| Price the fee is spent at | — | Often any price | Within 2% of a 30-minute average |
| What holders can claim | Nothing | Their share of the treasury | Their share of the nest, at any time |
Asked, answered.
What is a Fledge coin?
A coin with its own treasury, called its nest. A fee on every trade is swapped into one tokenized stock, NVDA say, and held by the coin’s contract. It starts life trading on its own curve. When the curve sells out it fledges into a Uniswap pool, and that pool’s fees keep filling the nest.
What exactly happens when a coin fledges?
The buy that takes the last of the 800 million curve coins closes the curve. In that same transaction, the ETH the curve raised (3 ETH) and the 200 million coins held back become a full-range position in the coin’s 1% Uniswap v3 pool, at exactly the price the curve ended on. The curve then refuses trades, and the coin trades on Uniswap. The buyer is refunded any ETH that was not needed.
Can anyone take the liquidity out?
No. The position is owned by the coin contract itself, and the contract has no function that removes liquidity. It has no owner and no upgrade either. The ETH and coins stay in the pool for as long as the chain exists.
What happens to the pool’s fees?
They go to the nest. Fees paid in ETH, which come from buys, are swapped into the stock at a fair price. Fees paid in the coin, which come from sells, are burned, so the supply shrinks and every remaining coin’s share of the nest grows. Anyone can press Harvest, and every redeem harvests first.
What stops someone setting up the pool before the coin fledges?
The coin will not move into its own pool before fledging, so nobody can add coins there first. Someone can still set a price in the empty pool, and fledging moves it back to the curve’s price before adding liquidity. The only liquidity that can be there is ETH-only, so moving the price back sells coins to it above the curve’s price. That favours the nest, and the extra ETH goes into it.
What stops someone pushing a stock’s price just before the nest buys?
The nest reads both pools’ time-weighted average price (30 minutes, or 10 or 2 if a busy pool has overwritten older history). It refuses to accept less than that average says, minus the pools’ fees and 2%. A price pushed inside one block carries no weight in the average, so the purchase waits instead of overpaying.
Can I get the nest out?
Yes, before or after fledging. Burn any number of coins and receive exactly that fraction of the nest: the stock, plus any fee ETH still waiting to be swapped. The fraction is taken over the whole supply, including coins still in the curve or in the pool, so nobody can take more than their share.
What does it cost to launch?
Only Robinhood Chain gas, a few cents, which also creates the coin’s Uniswap pool. 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 go to zero, stocks can fall, and Robinhood can pause a stock token. Only use money you can afford to lose.
Launch one. Watch it fledge.
Pick a stock and set the fee. The trading does the buying, and the curve does the rest.
