v1.1.9 OpenSea Collection Slug Optional Parameter
If you’re using an OpenSea Collections shared contract address you will want to include your Collection Slug when adding NFT assets for verification. This will require an OpenSea API Key, which support was added for in version 1.1.8.
By default, Web3 JS will check if the visitor or address owns any NFT asset on the smart contract address. If you are using a shared contract address, the address (website visitor) may own an asset outside of your OpenSea Collection. This would verify the address as true (owning an asset). By requesting an OpenSea API Key and including your collection slug in your MetaProduct assets, the system will check assets that are within your collection only.
