What is Vaults.fyi?
Vaults.fyi is the infrastructure layer for DeFi yield, offering a single API to embed DeFi capabilities into wallets, apps, and fintechs. It provides APY data, transaction execution, position tracking, and monetization across 80+ protocols on 20+ networks. Every rate is calculated from onchain contract data rather than scraped from protocol pages, with standardized schemas across all supported protocols. Vaults.fyi breaks out base, reward, and total yield per vault and provides reputation scores that factor in protocol track record, pool liquidity, and underlying asset risk. The portfolio API tracks real returns by logging every deposit and withdrawal across protocols, delivering precise P&L by position, vault, and time period without requiring custom infrastructure.
