Once you've uploaded your creation, you, as an original creator, gets 10% royalty on subsequent sales. This percentage is fixed and unable to change. 10% royalty is available only when the transactions are done in OurSong.
For example: You upload a work and sell it to collector A for $100, you'll receive "$100 - transaction fees". If collector A successfully resell it for $200, you'll get 10% of that sale price ($200*10%=$20) due to the royalty mechanism, and so on.
**Please note that once you or other owners withdrawn the creation to other marketplace (e.g. OpenSea), 10% royalty mechanism will no longer be applicable.
