Lending protocols rates parser

A phone-sized widget with USDC/USDT lending rates on Kamino, Euler and Aave, and how they move over time.

  • Widget listing USDC and USDT pools on Kamino, Euler and Aave with supply and borrow rates and 30-day sparklines
    All pools on one screen
  • Expanded Kamino pool with a 90-day supply rate chart, min and max, and a link to the protocol
    Tap a pool for its 90-day chart

Idea

Community members compared rates on the safest stablecoin pools by hand, protocol by protocol. The widget puts current supply and borrow APYs for 13 pools on one screen, with a 30-day trend per pool and a 90-day chart on tap.

A daily job records rates from DefiLlama's free API. Borrow-rate history is paid, so the collector keeps its own. Every pool links to its page on the protocol, to go and lend. The widget installs on a phone's home screen and needs no backend.

Business impact

One summary replaces checking each protocol separately.

Lending protocol rates were among the most valued activities of the Altseason community, and the community held 84% retention throughout the year.
