How coins launch, where the juice comes from, what you pay, and what can go wrong.

Overview

juiced.fun is a launchpad for memecoins on Robinhood Chain. Instead of pairing each coin with ETH, it pairs each one with a leveraged token — the juice — so a coin's dollar price moves with that position as well as with its own trading.

Every launch works the same way. There are no settings to tune, no team allocation and no migration later. You choose a market, give the coin a name, and the whole supply goes into a trading pool that stays open for good.

Juices

Every coin trades against one market, which you pick at launch. It can't be changed afterwards, because the pool's liquidity is locked to that pair.

BTC 3x longpBTC3x A leveraged long position on bitcoin. Rises when bitcoin rises.
HOOD 3x longpHOOD3x A leveraged long position on Robinhood stock. Rises when HOOD rises.
BTC 3x shortsBTC3x A leveraged short position on bitcoin. Rises when bitcoin falls.

A coin's price is set in its market token, not in dollars. If pBTC3x doubles in value and nobody trades your coin, your coin's dollar price doubles too. The same is true on the way down, and because these are leveraged positions they move further than the asset behind them.

Markets are listed in an on-chain registry, which can add or pause markets. The create page always shows the ones currently open for new launches.

How the price works

There's no separate bonding-curve contract. At launch, the factory opens a Uniswap-style pool with a 1% fee and places the entire supply in two ranges of liquidity sitting just above the opening price. Buying takes coins out of those ranges and pushes the price up through them. Selling puts coins back and moves it down.

Fully diluted value, at launch prices $509K $51K $3.5K First band 793.1M coins Progress counts this band Second band 206.9M coins Opening price. Buys move up through the bands, sells move back down.
Band heights follow their price ranges; widths follow how many coins each holds. Dollar values are fixed in the market token, so they rise and fall with it.
The first band
793.1 million coins, from the opening price up to 14.58 times higher. At launch prices that runs from about $3,500 to about $51,000 fully diluted.
The second band
The remaining 206.9 million coins, stacked directly above and running up another 9.97 times, to about $509,000 fully diluted at launch prices.

There's no graduation step. The pool a coin launches into is its market from the first trade, so it can be charted and traded like any other pair right away.

Launching a coin

  1. Connect a wallet Use a browser wallet such as MetaMask. If it's on another network, you'll be asked to switch to Robinhood Chain.
  2. Pick a market This decides what your coin is priced in, and it's permanent.
  3. Name it Names can be up to 32 characters and tickers up to 10. Each name and ticker pair can only be launched once.
  4. Add details, if you like A logo (PNG, JPG, GIF or WebP, resized to 256px), a description and links. These are saved after the coin is live, using a wallet signature that costs nothing.
  5. Buy on launch, if you like Enter an amount of ETH. It's swapped into the market token and spent inside the launch transaction itself, so nobody can buy ahead of you. This takes three confirmations: swap, approve, launch.
  6. Launch The site checks the market's latest price right before sending. The launch fails if that price has moved more than 5% or hasn't been updated in the past hour. That check runs before you're asked to sign, so it costs no gas. If you were buying on launch, the market tokens you already swapped for stay in your wallet and are used on your next try.
You don't receive any coins for launching. The whole supply starts in the pool, and the only way anyone gets coins, including the creator, is by buying them.

Buying and selling

Buying

You pay in ETH. The site routes it in a single transaction: ETH to USDG, USDG to the market token, then the market token to the coin. The first two steps are separate pools with their own fees, listed on the fees page.

Max slippage sets how far the price can move against you before the buy is cancelled. It defaults to 15%, because a new coin can move a long way between the quote and the transaction landing. You can choose 5%, 15%, 30% or 50%. Choosing Max leaves 0.0005 ETH in your wallet for gas.

Selling

Selling swaps your coins for the market token, not ETH. Sell a coin priced in pBTC3x and you'll receive pBTC3x. It takes two confirmations: approve, then swap. To end up with ETH, swap the market token separately.

Charts

New coins are charted from our own trade index. Once Dexscreener picks up the pair, its chart replaces ours.

Creator fees

Each coin's pool charges 1% on every buy and sell. Those fees build up inside the coin's locker until someone collects them, and are then shared three ways, in both the coin and its market token:

60% to the coin's creator
The wallet that launched it, for as long as the coin trades.
30% buys back the platform token
Spent on the open market, so trading volume across every coin feeds back into one token.
10% to the ecosystem
Runs the platform and funds what gets built on top of it.
How this is settled today: the locker contract itself sends 10% straight to the creator's wallet at collection and the remainder to the platform wallet. The rest of the creator's 60%, and the 30% buyback, are paid out by the platform from that side of the transfer. The split above is what a creator ends up with; the contract's own numbers are visible on the fees page.

Anyone can trigger a collection, and the payout goes to the same places whoever does it. The creator is the wallet that launched the coin and can't be changed. Each coin's on-chain split is fixed in its own locker at launch, so later contract changes don't affect coins that already exist.

Risks

Liquidation
Every market is a leveraged position. If it's liquidated, its value goes to near zero, and so does the value of every coin priced in it. A worthless market token can still be swapped into the pool, so a coin's supply can be drained for nothing.
Locked liquidity
Liquidity can never be withdrawn or moved to another market, including after a liquidation.
Copycats
Launching is permissionless, so anyone can launch any name, including copies of real projects. We hide known impersonators from the board, but they still exist and still trade. Check the contract address before you buy.
What nobody can do
Each coin contract has only the standard token functions. Nobody, including us, can mint more coins, pause trading or change a coin after launch.
What the platform controls
The factory owner can change the launch fee and the platform's share of trading fees for future launches. The registry owner sets the reference prices used at launch and can add or pause markets.

Contracts

All on Robinhood Chain. Each coin also has its own token, pool and locker, linked from its page.

The juice cuts both ways. Your coin is priced in a leveraged perpetual position: if that position is liquidated its value goes to near zero, and so does the value of everything held against it in this pool — a worthless quote token can still be swapped in, so the supply can be drained for nothing. Liquidity is locked permanently and cannot be moved to another market.
