How We Collect Data

We query blockchains hourly, processing millions of data points from heterogeneous vault implementations—from ERC-4626 standards to rebasing tokens to complex RWAs.

Our transformation pipeline normalizes these diverse data structures into a consistent, comparable format accessible through a unified API layer. Using our methodology, we can create apples-to-apples metrics (e.g. 1/7/30d avg. APYs) for onchain vaults and provide industry-leading v1 Market data for DeFi, including benchmark interest rates for stablecoins and for ETH.
