❓FAQ

Why do yields on vaults.fyi look different from other sources?

While other applications calculate interest rates using differing assumptions methodologies, we standardize yield calculations across our platform.

We calculate yields as 1 day / 7 day / 30 day trailing averages by observing changes in vault share price over each time frame. We believe this provides users a more accurate representation of vault performance vs. looking at more volatile interest rates over shorter (i.e. single block) timeframes.

We fetch data for these calculations directly from the blockchain, minimizing assumptions and reliance upon external APIs. For more information, read Methodology.

How often does data on vaults.fyi update?

Hourly. We fetch onchain data every hour.

How are new vaults added to vaults.fyi?

We add new vaults based upon customer request, with bias for protocols with significant traction.

Our team started with yield opportunities for stablecoins, ETH, and liquid staking tokens across several “blue-chip” DeFi protocols such as Aave, Compound, MakerDAO, Yearn, Lido stETH, and Rocket Pool rETH. Over time we have added many more protocols by user demand.

If you represent a protocol and would like your vault to be added to vaults.fyi, please submit this form. We research each protocol before integrating and appreciate communications with protocol teams.

How does vaults.fyi get its data?

To efficiently automate this process, we implement specialized smart contracts that fetch and transform data using a single function. These contracts are deployed in a static call, which is temporary and does not affect blockchain storage, thereby incurring any cost. This method allows us to read data directly from the blockchain. Our approach saves on calls and enables the use of one result to calculate the next within the same call, a technique not possible with standard multi-call processes. We use services like Infura, Alchemy, and Ankr RPCs to execute these calls. Once the data is retrieved, it is stored in our backend database.

What causes significant fluctuations in APY?

One challenge we face is accounting for the irregular intervals at which some vaults update their earnings — leading to sudden and significant fluctuations in APY. Understanding this nuance is essential for accurately interpreting discrepancies on vaults.fyi. See our methodology for more information.
