  • 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?
