Dune provides dashboards to track TVL for DeFi protocols (e.g., Aave, Curve). You can access community-created dashboards or write SQL queries to extract TVL data from smart contracts. For example, query the total assets deposited in a protocol’s contracts and visualize changes over time. Cross-reference TVL with protocol fees (available on Dune) to evaluate profitability. A project with high and stable TVL, as shown in Dune’s visualizations, often indicates strong fundamentals and higher value.
