Updating Operator Filter (Blocking Blur and OpenSea)

Learn how to update your royalty operator filter subscription to block trading/buying on Blur and OpenSea.

Operator filter is a tool or feature provided by some NFT marketplaces that allows users to control whether or not creator royalties are included when NFTs are traded or sold on their platform.

Subscribing to Lists: Not all NFT marketplaces automatically enforce royalties. To ensure that your royalties are respected and paid out appropriately, you may need to subscribe to specific lists or services.

If you want to keep your royalties, this guide will walk you through blocking specific operators and opt for NFT marketplaces like Magic Eden, which prioritizes creators' earnings.

With NiftyKit, all Ethereum Mainnet and Polygon Diamond Contracts (created March 14, 2023, onwards) are fully compatible with Magic Eden’s standards. Plus, we’re providing updated contract filters to ensure a seamless transition for our users.

Requirements

To complete this walkthrough, you will require:

• Your collection’s contract address

• Access to the wallet address you used to create the contract/collection (Collection owner address)

• Some ETH or Polygon in the owner's wallet for operation

Check if you are currently subscribed to the default registry maintained by OpenSea.

First, check if you are subscribed to the default operator filter registry maintained by OpenSea.

1. Visit the ETH OperatorFilterRegistry contract on Etherscan. If your collection is on Polygon, visit the Polygon OperatorFilterRegistry contract on Polygonscan.

If the above link did not already navigate you to the “Read Contract” tab, manually navigate to “Contract” > “Read Contract”. The UI should appear as follows:

2. Scroll down and find “10. isRegistered,”

3. Paste your collection’s contract address into the “registrant” field

4. select “query.” This query doesn’t need your wallet connected thus, it is safe and free.

The response will be “true” if your collection token contract is an existing registrant of the default Open Sea operator filter registry:

The response will be “false” if your collection’s token contract is not an existing registrant of the default Open Sea operator filter registry.

You are good if you are an existing registrant (query returns true). If not, please see the “How to switch to default registry” section. Once complete, please continue to the next step.

If your subscription address is 0xB197F889dd1550533A0F1112dbD5B12e5dded25d, you are subscribed to MagicEden default subscription. You are all set.
