Overview

long.xyz launches tokens on top of Robinhood stock tokens — pair a memecoin with NVDA, TSLA, SPY, or just ETH. There is no bonding-curve phase: the token opens straight into a Uniswap v4 pool whose liquidity is locked forever, with an anti-snipe fee that makes the first ten seconds unprofitable to bot. Launch Party launches through long.xyz's own contracts, so the token is listed on app.long.xyz.

  • Fixed supply of 1,000,000,000; no team allocation, no vesting; 100% of supply in the pool.
  • Starts at ≈ $20,000 market cap in the pair's live price.
  • No launch fee — gas only.
  • You are the on-chain creator; fees arrive in the pair currency.

Launching

The long.xyz form asks for a name, ticker, pair, image and description; optional links and private. The preview checks the ticker is free on long.xyz, prices the pair, and shows the starting market cap in that pair before you confirm.

Rules

  • Tickers are letters only, up to 15, and exclusive on long.xyz for 24 hours after any launch with that ticker.
  • No dev buy — the anti-snipe fee would eat it (see below). Use the buy buttons once it's live.
  • Gas ≈ 0.0001 ETH; your wallet needs ~0.001 ETH of headroom.

Pairs

The pair is what your token trades against and what buyers pay with: ETH, USDG, or any Robinhood stock token long.xyz lists (AAPL, AMZN, COIN, GOOGL, META, MSFT, MSTR, NVDA, PLTR, TSLA, TSM, SPY, QQQ, GLD and more — the field autocompletes and the list follows long.xyz's). The pair's live USD price sets the starting ticks so every launch opens at ≈ $20k market cap. Stocks priced only off-hours can occasionally be unavailable; the bot says so and suggests ETH.

Buying a stock-paired token doesn't require holding the stock: the buy buttons route ETH → stock → token in one transaction.

The pool & the first 10 s

Liquidity is placed once at launch: 99.1% of supply on a single range from $20k to $1.25B market cap, 0.9% above it, then locked. Price moves along that range as people buy and sell.

The pool's swap fee starts at 100% and decays in a straight line to 1.4% over the first 10 seconds. A bot that buys in block one gets almost nothing; the Launch Party buy buttons simply wait the window out.

Fees

Every swap pays two fees to different places:

  • 1.4% hook fee → long.xyz (5% of it to Doppler, the protocol under long.xyz; part is reinvested into the pool). This is the same on app.long.xyz — a token that routes it elsewhere is delisted as fake.
  • 0.1% LP fee → 95% to the creator side, 5% to Doppler. Launch Party's 10% comes out of the creator side.
The creator's share is where our 10% comes from; every other slice is the venue's own fee.

Fees arrive in the pair currency — ETH for an ETH pair, NVDA for an NVDA pair — plus a little of the token itself.

Claiming

LP fees accumulate in the pool until they're collected. When you claim, the bot collects them into your launch's fee wallet and pays out 90% to your wallet, 10% to the platform, then DMs you the amounts. Claim whenever you like.

Hook fees never pass through here — they are long.xyz's, paid to long.xyz on every swap.

Listing on long.xyz

long.xyz only lists tokens created through its own launch contracts with its exact configuration — supply, pool setup, fee schedule, fee recipients. Launch Party matches it field for field, so your token shows on app.long.xyz within about a minute of launch, with the image and description you gave. The announcement links straight to its page.
