Arc said on October 8 that Earn Kit is available to builders. The integration layer connects USDC balances in Arc applications to selected Morpho Vaults and exposes deposit, position tracking and withdrawal operations through developer-facing APIs. Integrators retain control of the user interface while Morpho supplies the noncustodial lending infrastructure underneath.

The kit reduces integration work but does not turn variable lending yield into a guaranteed return. Arc says it does not own, curate or recommend the underlying markets, and warns that deposited assets can be lost. Users remain exposed to smart-contract, collateral, curator, liquidity and oracle risks. Adoption should be measured through actual integrations and deposits rather than the availability of the SDK alone.
