While there are no fees to create/launch coins, every trade (buy or sell) includes a total fee of:
1.5% of the trade amount
where, 1.0% goes to Protocol treasury,
and, 0.5% goes to Coin creator
This fee helps to reward creators and support the protocol.
For more details, defer the official fees page on Sikka.fun platform.
Note, referral rewards are minted from the referral pool and do not impact the fees paid by traders. Referral tokens are minted only when qualifying buy transactions occur. If part of the referral pool is never used, those tokens are never created and never enter circulation.
