Quix and Stratos are both Layer 2 NFT marketplaces. Functionally, both platforms work exactly the same way and help center articles for any operation will apply both of them. The only difference between the two platforms is that Quix hosts NFT collections deployed on the Optimism Layer 2 network, while Stratos hosts NFTs on the Arbitrum Layer 2 Network.
We do not have plans to combine the two platforms into one centralized marketplace yet, but have created the codebase to allow us to do that if we decide to in the future.
