> The example shows developers how users can borrow USD Coin against cirBTC, monitor a loan and repay it.

Arc has released an open-source example app for adding USD Coin (USDC) borrowing to crypto applications, demonstrating a loan workflow backed by cirBTC for developers integrating lending features.

The example walks through exploring lending markets, choosing a loan amount and depositing cirBTC as collateral. Users can then borrow USDC, monitor the health of their position, repay the loan and close it.

Built with Borrow Kit, the app is intended to show how developers can add crypto-backed borrowing without writing custom smart-contract code or maintaining a direct integration with a lending protocol.
