After the Layer 2 solution is released, if you have already minted domains and are wondering how to determine whether the domain is currently on Layer 1 (Ethereum) or Layer 2 (Polygon), there are a couple of methods you may use to identify.
We will also be adding a feature to our website to allow users to easily differentiate whether the domain currently on Layer 1 or Layer 2. More information we will be provided shortly.
Click the domain in question.
If the domain is on Layer 1, the URL will begin with: https://opensea.io/assets/
If the domain is on Layer 2, the URL will begin with: https://opensea.io/assets/matic/
