Arc’s Earn Kit lets apps add USDC yield without smart-contract code

Apps can now add onchain USDC earning without building the smart contracts themselves. Arc’s Earn Kit packages the yield experience as an integration for developers, moving the work from custom contract development to the application layer.

That lowers the implementation burden for teams adding USDC-based earning features. Arc announced Earn Kit on September 28, 2026, and the product requires no smart-contract code from developers.
