Royalties
Royalties are not a suggestion here. They are the entire revenue model for holders.
The number
Every secondary sale routes 10% of the price to the vault, and 90% of that is split across every share in the collection.
Net to a holder: 9% of every sale, weighted by how much share they hold.
How a marketplace knows
Turtle Fees implements EIP-2981, the on chain royalty standard. A marketplace asks the collection contract before it completes a sale and gets back two things: who to pay and how much.
Call royaltyInfo(id, salePrice) on the collection yourself. It answers with the vault address and 10% of whatever price you pass in.
Because it is on chain, the answer travels with the token. Any compliant venue pays the vault automatically, without us asking and without an integration.
Where it goes from there
Straight into the vault, where it is split and credited to every share in the collection.
Why 10% and not 5%
Most collections take 5% and keep it. We take 10% and send 90% of it back to the people holding turtles.
A holder is better off under a 10% royalty they receive than a 5% royalty they do not.
What we do not do
We do not block marketplaces. Blocking venues kills liquidity, and thin liquidity hurts every holder more than an unpaid royalty does. v2 leans on EIP-2981 and on venues honouring it.
OpenSea is the main venue on Robinhood Chain today and it honours creator set on chain royalties.
