Solana is the only top-10 L1 chain that doesn’t have fee data shown, and also one of the most-requested protocols.
Unfortunately, I haven’t found any data sources for Solana, and there’s no open indexing protocol that can be leveraged either.
I’ve reached out to the team from SolanaBeach to see if they can put together an API. But if anyone else knows a good data source, please share here.
