# Fee Structure

Each buy and sell on the bonding curve incurs swap fees for that specific collection. Each swap from gNFT to collection key in the GumBall Machine also incurs a fee.&#x20;

Fees are set by creators for each collection.&#x20;

Bonding Curve swap fees can be set from 2.5-10%

GumBall Machine fees can be set from 0-10%

Each collection's fees accumulate in their respective Fee Treasury over time as swaps/redemptions occur. A skim function can be called by anyone at any time to transfer the tokens in the treasury to their appropriate addresses.

Fee Treasury Split is

* 40% to the collection creator
* 40% to stakers
* 20% to GumBall Treasury

Royalties from third party marketplaces such as Opensea are distributed to the collection creator as well.&#x20;
