Is there any website which tracks the number of Bitcoin transactions, fees and amounts associated with layer 2 projects (Lightning Network, Liquid, Rootstock)?
I am curious about this because if a sidechain like Liquid doesn't really contribute to some Bitcoin transactions, fees and has different trust assumptions is that helping Bitcoin in anyway?
Will this become difficult to know after enough people start using Taproot? It should be good for privacy but it helps if you know how much a layer 2 project affects layer 1 in different ways.
https://bitcoinkpis.com/layer2 has some information about LN but nothing about transactions.
https://bitcoin.clarkmoody.com/dashboard/ has information about bitcoin locked or used in Liquid but no transactions.
https://explorer.rsk.co/ also mentions bitcoin locked/used.
