New Solana coins launch on a Meteora bonding curve, so Jupiter and other apps can trade them as well, before and after graduation. The trade is the same curve or pool trade, whichever app you use.
The fee split is the same. One difference: when you trade on memewar.zone, Meteora pays a small referral back to MemeWarzone. In other apps that referral does not come to MemeWarzone.
