Token creation is free (gas only). Creating makes you the creator — you earn a 0.30% cut of trading fees. Optionally buy in the same transaction (initialBuy) to snipe at the curve opening price.
Launch fee … (anti-spam; once the curve fills, graduation happens on-chain automatically — no listing fee ever)
Sniping requires a vvXEN approval first; if allowance is insufficient you will be asked for the approval tx, then the launch tx.
