Idle Finance

Idle Finance is a decentralized yield automation protocol that has operated since 2019, enabling users and integrators to optimize yield generation across DeFi. The platform offers REST APIs for querying Best Yield and Yield Tranches pools, APY and TVL metrics, historical rates, and governance staking information. Idle aggregates yield sources across protocols such as Compound, Aave, Morpho, and Clearpool, and supports multiple chains including Ethereum, Polygon, Polygon zkEVM, and Optimism.

Idle Finance publishes 3 APIs on the APIs.io network: Pools API, Rates API, and TVL API. Tagged areas include DeFi, Yield Optimization, Finance, Crypto, and Staking.
