Episode notes

Edit these notes…

OpenSea will demonitize if you list on other marketplaces

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
- Background
  - https://support.opensea.io/hc/en-us/articles/1500009575482
  - https://x.com/opensea/status/1592358043588915202
  - https://x.com/fulldecent/status/1596263336630702080
  - 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?
- See EIP-1153 royalty router
