Launch on long.xyz

A Doppler multicurve pool that can trade against a tokenized stock.

Why long.xyz

long.xyz creates a locked Doppler pool through its launcher. Your coin can be paired with ETH, USDG, or a tokenized stock (NVDA, AAPL, TSLA, SPY, …), so it trades in the same market as the stock. LP fees stream to beneficiaries: 95% to the platform (50% of which goes to your payout wallet) and 5% to Doppler.
