Ecosystem Dashboards

Our docs are now available at dune.com/docs. We'll keep this around as a reference, but we won't update them and eventually plan to deprecate.
Since Dune has all the data in one place you can also check more general metrics.

Gas Prices

You can easily assemble the data on average gas spent per tx, gas limit, gas spent in total in a block etc. using Dune.
Data on gas spent and similar metrics can also be relevant to certain protocols, so do keep this in mind.

DeFi Adoption

Richard Chen has compiled the user numbers of all important DeFi Protocols and compiled them in one Dashboard.
