The Marketplace Blocker app provides a creator controlled alternative to Opensea’s Operator Filter. The Marketplace Blocker app lets you manually create your own marketplace blocklist to restrict the sale of tokens on selected marketplaces.
While we don't agree with blocking marketplaces we believe in giving creators the power to choose. If a creator would like to participate and opt-in to OpenSea's policy on royalties, they may now do so on their own terms with the Marketplace Blocker.
If you’re not sure how or why this would affect you, some background:
Recently, OpenSea updated their policy on creator-fees to not enforce royalties unless the contract contained code (the Operator Filter) to block the selling of NFTs on a specific list of zero-royalty marketplaces. The marketplaces on this list are controlled by CORI, a consortium of companies including ZORA, OpenSea, Manifold, Foundation, Super Rare and Nifty Gateway. By opting into the Operator Filter, you delegate control of a marketplace blocklist managed by this consortium.
The Operator Filter can be enabled in your contract settings on Manifold Studio.
Any contract with its first token minted after OpenSea’s January 2nd, 12PM ET deadline that does not contain this code will not be eligible for royalties on OpenSea. Contracts with their first token minted before this deadline are automatically grandfathered in for OpenSea royalty eligibility.
Yes. All contracts are impacted.
Enabling either the Operator Operator filter or manually blocking the CORI-required marketplaces at the contract-level will be required before collection creator-fees (royalties) can be configured on OpenSea.
