Arc Unveils Developer Kits for Stablecoin Purchases, Lending, and Bitcoin-Backed Borrowing

Arc, the blockchain subsidiary of Circle, has launched three developer kits for apps on its mainnet. The Onramp Kit allows developers to embed $USDC and $EURC purchases into their own products, supported by debit cards, Apple Pay, Google Pay, and bank transfers in select jurisdictions.

The Earn Kit lets apps offer $USDC and $EURC deposits into lending vaults on Morpho, which includes vaults lending into markets backed by ETH and BTC collateral. Deposited funds sit in vault contracts, not with the software provider.

The Borrow Kit uses cirBTC collateral to obtain $USDC, combining posting collateral and borrowing in one transaction on Arc. Apps can subscribe to updates when a loan's health changes, but liquidation risk remains present.
