Case Study: Etherscan Cards

PreviousGet estimated returns for user's vault position

Last updated 16 days ago

The vaults.fyi API provides reliable onchain analytics for DeFi yields, as well as transactional support for leading protocols.

This case study explores our collaboration with Etherscan, showcasing how the Insights API enhances user experience and provides contextual insights to Etherscan users through its Cards tab.

How It Works

  1. Balance checks: When a user views an Ethereum address on Etherscan, our Insights API detects idle balances of ETH and stablecoins (currently USDC, USDT, and DAI).

  2. Find matching vaults: Etherscan queries the Insights API to find the top yield opportunities for the detected ETH and stablecoins that meet specific criteria (outlined below).

  3. Present : Concise information is presented to the user through the Yield Opportunity card on Etherscan (see vitalik.eth here for example), showing the user potential yield opportunities to investigate.

  4. User Action: Users can click the card to see more on vaults.fyi, where they can find additional analytics as well as supply, withdraw, and manage their wallet funds.

Criteria

The Etherscan Cards integration surfaces opportunites that meet the following criteria:

  • ETH: Displays the highest 7d APY available among ETH vaults where Total Value Locked (TVL) exceeds $100 million.

  • Stablecoins: Displays the highest 7d APY available among USDC, USDT, and DAI vaults where Total Value Locked (TVL) exceeds $100 million.

Integration

The Etherscan Cards integration is one example of the vaults.fyi API in action.

With our Insights API and Earn API, builders can easily:

  • Provide real-time, accurate yield data

  • Connect users to leading DeFi opportunities

  • Create frictionless in-app (native) onchain experiences
