Arc's Earn Kit Lets Builders Offer USDC Yield Without Smart Contracts

Circle's Earn Kit, part of the Arc App Kits SDK suite, lets developers offer onchain USDC earn experiences without writing smart contract code. The kit connects applications to lending markets such as Morpho, allowing users to earn yield on USDC without leaving the host app's interface.

The announcement promotes Earn Kit as a fast path for builders to add earn products on Arc, alongside other App Kit components like Onramp Kit for fiat-to-USDC funding. It extends the developer tooling available on Arc as Circle pushes stablecoin earning into standard app features.
