🏦Overview

Vaults.fyi connects users directly to 500+ DeFi vaults across 50+ protocols and 10+ blockchain networks.

We index and normalize data and interactions across protocols, enabling our users to:

1. Get accurate, standardized market data on onchain lending and staking activity across DeFi's leading protocols.

2. Make DeFi integrations a breeze, using one simple interface to prepare transaction payloads, generate personalized insights, and fetch user balances and positions across nearly all of DeFi.

Vaults.fyi is entirely non-custodial, preserving users' autonomy and security.

Our infrastructure transforms diverse protocol data across multiple blockchains into a standardized layer that can power detailed analytics, transactional support, and portfolio tracking.

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.
