Vaults.fyi covers over 80 DeFi protocols across more than 20 networks. For each supported protocol, you get standardized market data — APY, TVL, fees, and reputation scores — through the same API endpoints, regardless of how each protocol is implemented under the hood.

​
Analytics vs. transactional support

Not all protocols have the same level of integration. Coverage falls into two tiers:

Analytics support

Market data is available: APY, TVL, fees, historical rates, and reputation scores. You can query and display vault data but cannot prepare transaction payloads.

Transactional support

Full integration: market data plus ready-to-sign deposit, redeem, and claim transaction payloads. Users can interact with the vault directly through your app.
To check whether a specific vault supports transactions, call GET /v2/transactions/context/ for that vault. If transactional actions are unavailable, the response will indicate which steps are supported.

​
Key protocols

The following protocols are among the most widely used on Vaults.fyi:
  • Aave — the largest decentralized lending protocol, available across multiple networks
  • Morpho — modular lending built on top of Aave and Compound
  • Euler — permissionless lending vaults with flexible risk parameters
  • Spark — MakerDAO’s lending and savings layer
  • Lido — liquid staking for ETH with broad DeFi integrations
  • Compound — one of the original on-chain money markets
  • Yearn — automated yield aggregation with multi-strategy vaults
These protocols represent a cross-section of the 80+ covered. For the authoritative list, query GET /v2/protocols directly.

Query GET /v2/networks to get the live list of supported networks with their chain IDs. Use the chain IDs when filtering vault queries by network.

​
How coverage expands

Vaults.fyi continuously adds new protocols and networks. When a new protocol launches or reaches meaningful TVL, it goes through a review and integration process before appearing in the API. To check the current state of any protocol or network programmatically, use the reference endpoints:
  • GET /v2/protocols — returns protocol names, products, and versions
  • GET /v2/networks — returns supported networks with chain IDs
These endpoints always reflect the live state of the API, so they are more reliable than any static list.
