API

The Definitive API lets others build on Definitive’s yield and execution infrastructure. The API streamlines and standardizes multiple DeFi protocols within a single unified strategy interface. Today, with just a few lines of code, wallets, custodians, and aggregators can easily launch a DeFi Earn product for their users with Definitive’s powerful infra as foundational bedrock!
