DeFi Yield & Metrics
Signed DeFi yield rates and protocol metrics across 15+ protocols on Base, Ethereum, and Arbitrum. Supply APR, borrow APR, TVL, and utilization — cryptographically attested on every query.
Overview
Two data feeds: yield rates (supply and borrow APR per protocol and asset) and protocol health metrics (TVL, utilization, chain breakdown). Data sourced from on-chain state and DeFiLlama.
These are Layer 1 raw measurements. For risk-adjusted yield rankings that account for current market stress, see Layer 3 DeFi Opportunity.
