Arc has open-sourced a USDC borrowing sample application built on its Borrow Kit, enabling developers to rapidly integrate crypto-asset collateralized lending into the Arc ecosystem. The release aims to streamline implementation by providing a ready-made framework for decentralized borrowing functionality. The sample app demonstrates a complete lending workflow, including market discovery, loan sizing, cirBTC collateral deposits, USDC borrowing, position health monitoring, and repayment. Developers can now embed crypto-collateralized borrowing features without writing custom smart contracts or maintaining direct integrations with lending protocols.
