# 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. Fees are set by creators for each collection. 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
