# Tezoro > DeFi Yield Leaderboard - honest net yields, TVL and risk across 2,000+ markets on Ethereum. Tezoro is an independent DeFi data platform that tracks real on-chain yields across major lending and vault protocols. Unlike most aggregators that display protocol-advertised rates, Tezoro measures actual historical returns by reading smart contract state directly from Ethereum archive nodes. ## Key Facts - Covers 2,000+ markets across Aave V3, Spark, Compound V3, Euler V2, Morpho Blue, Morpho Vaults, and Fluid - All data sourced directly from Ethereum archive nodes - no third-party APIs - Hourly snapshots of share prices, TVL, utilization, and revenue - Asset prices from Chainlink on-chain oracles - AI-driven risk engine assigns tiers A (low), B (moderate), C (elevated) - Net APY excludes protocol incentives and reward tokens - shows real yield only - Completely independent: no paid listings, no data manipulation - Company: Tezoro, Inc. ## Risk Tiers - **A (Low risk):** Core lending/staking markets with TVL > $100M (Aave, Spark, Compound, Morpho Blue) - **B (Moderate risk):** Markets with reputable maintainers, significant TVL (Morpho, Euler, Fluid) - **C (Elevated risk):** Markets with at least 50% of max security score and TVL > $1M ## Net APY Calculation For vault-based protocols (Euler, Fluid, Morpho Vaults): tracks share price growth (totalAssets/totalSupply). For lending protocols (Aave, Compound, Spark): tracks accrued revenue relative to average TVL. Both methods use hourly on-chain snapshots over configurable periods (Day, Week, Month). ## Links - Website: https://tezoro.io - App: https://app.tezoro.io - Research: https://tezoro.io/research - X/Twitter: https://x.com/tezoroio - LinkedIn: https://www.linkedin.com/company/tezoroio - Contact: hello@tezoro.io
