Episode notes
OpenSea requires all new NFT projects to enforce on-chain creator fees, or get demonetized
Is this anticompetitive in an illegal or disallowed way?
Why didn’t OpenSea just let people opt-out of royalties?
Feels like the artist is being held for ransom rather than actually being helped

How contracts can specify owners and royalties on-chain
EIP-173 ownerOf is the way to identify artists today
EIP-2981 NFT Royalty Standard
Implementation example
https://github.com/LightArtists/light-smart-contracts/blob/v2-metadata-editable/contracts/Light.sol
onlyAllowedOperatorApproval modifier
Is this still better for artists than what was before OpenSea/NFT marketplaces?
Spent all this time writing documentation and tweeting about it, but didn’t even implement it in their own store yet
An extension for token contracts: make setApprovalForAll cheaper
Use messages, Gas-free setApprovalForAll
Extension of 20/721/1155
Doesn’t change how royalties work, if users want to apply royalties
Breakdown explanation
Have to Approve when listing on OpenSea
Signed message doesn’t need to settle on-chain until you actually transfer the token
Anyone who works at Blur, X2/Y2, Rarible, Looksrare to try this out?
