Problem
Developers building wallets, fintech apps, and other consumer platforms struggle to integrate DeFi yield features due to fragmented protocols, inconsistent data formats, and complex transaction building. Manually integrating and maintaining connections across multiple lending and staking protocols takes months, delaying time-to-market and limiting user access to yield opportunities.
Solution
Vaults provides an API for onchain finance that lets developers ship DeFi yield features in days, not months. The platform offers normalized market data, transaction calldata, and portfolio tracking across 80+ protocols and 20+ EVM chains, with Solana/SVM vault coverage in Beta. Vaults.fyi prepares the calldata, the user's wallet signs it, and the protocol executes it directly—no intermediary contracts, no custodian, and funds remain in the protocol. The API includes accurate APYs, reputation scores, and P&L tracking, enabling teams to build yield discovery, deposit, and position management flows without maintaining protocol integrations themselves.
Target Audience
Primary customers are wallets, exchanges, neobanks, fintech apps, portfolio tools, and aggregators seeking to embed non-custodial earn and borrow experiences into their products, as well as analysts and protocol teams needing yield data and risk context.
