About Vaults.fyi

Vaults.fyi is a dashboard that aggregates and tracks yields from over 500 DeFi vaults across 50+ protocols on Ethereum and Layer 2 networks. It provides standardized data on lending, staking, and other yield opportunities, allowing users to manage their DeFi positions efficiently.

Vaults.fyi is a powerful, non-custodial platform that aggregates and standardizes onchain DeFi yield data from over 500 vaults across 50+ protocols. Designed as the homepage of onchain yield, Vaults.fyi empowers users with seamless access to lending, staking, and liquidity opportunities across Ethereum and Layer 2 ecosystems.

The platform connects users to leading protocols like Aave, Compound, Lido, Morpho, Spark, Yearn, and Euler, offering real-time analytics, smart contract interactions, and standardized performance data. Built for both individual users and developers, Vaults.fyi combines robust analytics with intuitive UI, becoming the go-to gateway for anyone looking to earn optimized, verifiable yields directly from the blockchain.

Vaults.fyi is designed as the central access layer for discovering and interacting with the highest-yielding, most secure opportunities in decentralized finance. It indexes and updates hourly yield data from a wide range of integrated vaults, presenting it through a unified interface that facilitates one-click contract interactions like supplying, withdrawing, or claiming rewards. Unlike aggregators that only show data, Vaults.fyi also allows users to act directly from the platform — with full non-custodial control.

Vaults.fyi stands out by providing accurate APY metrics derived from indexed onchain data, offering 1-day, 7-day, and 30-day averages across assets such as USD stablecoins, ETH, and liquid staking tokens. Its transparency is elevated by detailed breakdowns between base asset yield and reward token incentives, helping users answer the essential question: “Where does the yield come from?”

What truly sets Vaults.fyi apart is its dual offering of consumer-facing yield tools and developer-first APIs. The Insights API delivers contextual, wallet-aware yield analytics and DeFi pool metrics, while the Earn API offers developers a way to generate calldata for lending, staking, or reward interactions in any integrated protocol. Position tracking, protocol benchmarking, and transaction simulation features further empower both casual users and builders alike.

Entirely non-custodial and trustless, Vaults.fyi eliminates the need for intermediaries by routing user interactions directly through smart contracts. Whether you're a retail investor browsing for the best yield on stables, or a protocol building with TVL visibility tools, Vaults.fyi delivers precision and usability without compromising on decentralization. The project’s growing popularity is reflected in its adoption by onchain experts and public praise from DeFi analysts across platforms like Farcaster and Twitter.

While other platforms like DeFiLlama or Yield Yak focus either on aggregated dashboards or native vault strategies, Vaults.fyi merges those functions with deeper smart contract access and unified cross-protocol analytics. It’s not just about yield discovery — it’s about enabling direct, informed, and actionable participation in the DeFi economy.

Vaults.fyi offers unique advantages that make it a leader in the DeFi yield aggregation landscape:

Cross-Protocol Aggregation: Access over 500 vaults across 50+ DeFi protocols like Aave, Spark, Morpho, and Yearn through a single dashboard.
Real-Time APY Data: Hourly updates on 1D/7D/30D yield metrics derived directly from indexed onchain data — no estimations or extrapolations.
Standardized Yield Analytics: Yield data is broken down into base and incentive sources, enabling transparency in understanding yield origin.
Non-Custodial Smart Contract Access: Supply, withdraw, and claim rewards directly from Vaults.fyi with full control over your wallet and funds.
Developer-Friendly APIs: The Earn and Insights APIs allow DeFi builders to integrate vault interactions and real-time analytics into their products.

Vaults.fyi FAQ

Vaults.fyi collects onchain data directly from protocol smart contracts and node providers, then computes standardized 1-day, 7-day, and 30-day APYs using consistent methodology across all integrated vaults. These metrics are updated hourly, ensuring high accuracy and comparability. This eliminates confusion caused by different APY formats or calculation methods across protocols like Aave, Morpho, Compound, and Lido. Learn more at Vaults.fyi.
Vaults.fyi focuses on providing actionable, standardized yield data along with direct, non-custodial smart contract interactions. While platforms like DeFiLlama are strong on TVL tracking, Vaults.fyi enables users to supply, withdraw, and claim rewards in one click — all from the interface. It also offers detailed APY breakdowns and wallet-aware insights through APIs, making it ideal for both end users and builders.
The Insights API provides developers with real-time yield metrics, historical returns, TVL benchmarks, and contextual insights tailored to user wallets. The Earn API enables the generation of calldata for interacting with smart contracts across 50+ DeFi protocols. These APIs allow apps, wallets, and dashboards to integrate lending and staking functionality without needing to build protocol-specific logic. All APIs are non-custodial and safe to deploy in production.
Yes. Vaults.fyi is not just a data aggregator—it’s also a fully integrated interface for direct smart contract interaction. Users can supply assets, withdraw funds, and claim rewards directly from the platform using their own wallets. Transactions are simulated in advance to ensure safety, and no intermediaries ever take custody of your funds. Learn more by visiting Vaults.fyi.
Vaults.fyi maintains a fully non-custodial architecture, meaning it never holds or controls user funds. All interactions are routed through verified smart contracts on-chain, with users executing them directly from their wallets. There’s no sign-up, no intermediaries, and no third-party custody — which preserves user sovereignty and ensures trustless access to DeFi yields. This design aligns with core Web3 values of decentralization and transparency.
