What does verification mean here? It is certainly not a guarantee that the project is successful, that it can't be a scam, etc. There is only a higher probability (no guarantee) that the token you are looking at is what it claims to be, or that the NFT policy belongs to the official. This process must be done by the author/creator.
requirements: use official account linked to asset ClayNation7899, you must have for twitter verification min 100 followers; you cannot verify project from your private twitter
