MetisDAO is a layer 2 launch since 2021. Before 2022, there isn’t a lot of dApps. But since several weeks some big dapps launched on MetisDAO ( for example QiDAO or Sushiswap). There are 25 dApps on Metis and 25 millions TVL ( for Defilama). I think it will be great to add MetisDAO data in the Covalent API.
