DeFi Yield Data Demands a Higher Standard
General DeFi data helps teams understand markets. Institutional yield evaluation needs evaluation-ready data: APY methodology, curator context, fees, capacity, history, warnings, and operational state.
Institutional teams evaluating onchain yield need more than prices, protocol TVL, token metadata, and wallet balances. They need data that explains what a vault owns, who manages it, how APY is calculated, what fees apply, how capacity changes, and whether one vault can be compared to another across protocols.
That is why DeFi yield data is its own category.
General DeFi data providers help teams understand markets. Portfolio APIs help teams understand wallets. Evaluation-ready yield data gives teams the vault-level context they need to understand yield products. For asset managers, custodians, tokenization platforms, and institutional research teams, that distinction matters because the work is not only discovery. It is screening, monitoring, methodology, and repeatable comparison.
Three ways teams source DeFi data
Every team working with onchain data chooses a starting point.
Raw data comes from an indexer or a node: decoded events, balances, contract calls, block by block. It is flexible because it assumes little about the protocol. The tradeoff is that your team owns the interpretation layer. You decode logs, reconcile protocol upgrades, normalize schemas, and keep the pipeline current as contracts and markets change.
Ready-to-use market data is pre-built and normalized. General data and analytics providers like Kaiko, Amberdata, Nansen, Glassnode, CoinAPI, and DefiLlama do this well for prices, flows, liquidity, protocol TVL, and broad onchain activity. Portfolio APIs like Zerion, DeBank, CoinStats, and Moralis do it for wallet balances and account-level history.
The evaluation-ready layer starts from a narrower question: which yield products exist, how do they compare, and what facts does a data team need before one of them can appear in a research workflow, product review, or allocation screen?
That question has a higher standard because a vault is closer to an investment product than a token quote. Two USDC vaults can sit on the same chain, lend into similar underlying markets, show similar headline APYs, and carry different economics because of curator behavior, capacity, allocation history, reward accounting, withdrawal constraints, and fees.

The first two categories are familiar. The third is the layer most "DeFi data provider" lists miss.
Why yield has a higher data standard
A useful yield dataset needs to answer questions that general protocol and wallet data usually do not answer in one place:
- Which protocol and network does it use?
- Who is the curator or risk manager?
- What is the current 7d avg APY and 30d trailing APY?
- Does the APY include rewards, base yield, or both?
- What fee(s) are charged, and is it a performance fee, management fee, or another structure?
- What is the current TVL, capacity, and remaining deposit room?
- What is the withdrawal path, and are there pending request mechanics?
- How has share price moved over time?
- How has the vault performed against a network-level USD or ETH benchmark?
- Are there active warnings, incidents, or methodology caveats?
Those fields have to be normalized across protocols. Aave, Morpho, Euler, Fluid, Ethena, Pendle, Veda, Spark, and Sky do not expose the same raw shape. Curated vault systems add another layer: the protocol provides the market, the curator chooses allocation and risk policy, and the vault becomes the unit an allocator actually evaluates.
For a data team, the job is not to collect every raw field. The job is to make vaults comparable without erasing the differences that matter.
The quality gap shows up in institutional workflows
The gap becomes visible when a team moves from market research to product or allocation review.
A research analyst can use a general DeFi dataset to see that Morpho TVL is growing or that stablecoin lending rates moved this month. An institutional data team needs to go deeper. It may need to compare Gauntlet, Steakhouse, Re7, MEV Capital, and other curator-managed vaults across chains. It may need to separate base yield from token incentives. It may need to rank vaults by 30d trailing APY while excluding active warnings and enforcing minimum TVL.
A product team has a related problem. It may never route transactions through an external execution API, but it still needs clean data for vault screening, recommendations, disclosures, historical charts, and internal review. The same applies to tokenized fund platforms and custodians that are evaluating how onchain yield should sit next to stablecoins, money market funds, staking, and other digital asset products.
If the yield data is not standardized, every internal workflow becomes a one-off integration project. The team ends up maintaining protocol adapters, curator mappings, APY conventions, reward handling, fee parsing, share-price history, and warning logic before it can answer the first product question.
What standardized yield data should include
The minimum institutional-grade yield dataset has five layers.
First, discovery. Teams need coverage across protocols, networks, assets, tags, curators, TVL thresholds, capacity, and warnings. Discovery is the difference between "show me USDC vaults" and "show me USDC vaults on Ethereum and Base with more than $25M TVL, no active warnings, named curator metadata, and 30d trailing APY above the USD benchmark."
Second, methodology. APY should specify the window and whether rewards are included. A 7d avg total APY that includes token incentives is not the same as a 30d trailing base APY excluding rewards. Both can be useful. They should not be mixed silently.
Third, historical context. A current yield number is a snapshot. Data teams need APY history, TVL history, share-price history, benchmark comparison, and enough continuity to see whether a vault is stable, seasonal, reward-driven, or reacting to a specific market condition.
Fourth, curator and fee context. The curator layer is one of the most important differences between DeFi yield and general protocol analytics. Curators set policy, manage allocations, and often define the actual risk/return profile. Fees matter too because displayed APY is usually net of some fee structure. Comparing net APYs without understanding the fee layer can hide the economics of the product.
Fifth, operational state. Capacity, deposit limits, warning flags, withdrawal paths, and pending request mechanics belong in the dataset. These fields matter even when the buyer only wants analytics. A vault that looks attractive on APY but has constrained capacity or a queue-based exit path is a different product from one with deep available liquidity and simple redemption mechanics.
Where vaults.fyi fits
vaults.fyi is built for this narrower category: standardized, evaluation-ready DeFi yield data.
The API covers 1,000+ yield strategies across 80+ protocols and 20+ networks. It exposes vault discovery, APY and TVL data, historical time series, benchmarks, curator-aware filtering, portfolio positions, and optional transaction infrastructure through one surface.
The data model is built around the vault as the unit of analysis. That matters because institutional teams rarely evaluate DeFi in the abstract. They evaluate specific products: a USDC vault on Base, a curated Morpho vault on Ethereum, a stablecoin strategy managed by a named curator, or an ETH-denominated vault that needs to clear a benchmark after fees and rewards are accounted for.
Gauntlet, Chaos Labs, and KPK use vaults.fyi as data customers and curator partners. Kraken and Jumper use the same underlying infrastructure in user-facing earn products. Those use cases are different, but they depend on the same thing: reliable vault-level data that is normalized across protocols and chains.
Transaction infrastructure is available when a team needs it. It should not be the only reason to use vaults.fyi. For many institutional teams, the first use case is research, screening, monitoring, or internal analytics. That is where standardized yield data creates value before any execution workflow is in scope.
How should you choose a DeFi data provider?
When the goal is yield evaluation, the category label on a vendor list is the wrong filter. General data providers, portfolio APIs, and yield infrastructure all appear under "DeFi data" and solve different problems.
One question sorts them: after you integrate this data, what does your team still have to build before it can compare vaults with confidence?
For raw data, you'll still need to build most of the interpretation layer. For ready-to-use market data, you'll need to build yield-specific models. With evaluation-ready yield data, the data arrives so that your team can act upon it.
If you are deciding where your yield data comes from, start with that question.
