Circle Internet Financial has announced the availability of USDC, a fully reserved, dollar-backed stablecoin, natively on the Polkadot Asset Hub, making it accessible to developers and users within the Polkadot ecosystem. This integration allows for seamless transfers of USDC to various parachains on Polkadot via the XCM protocol, facilitating global payments, remittances, and 24/7 trading, borrowing, and lending on platforms such as Centrifuge, HydraDX, and Moonbeam. Businesses and developers can utilize Circle Account and Circle APIs to convert fiat currency to USDC and engage in new use cases without the need for traditional bank accounts. However, users must be cautious about transferring USDC between Polkadot Asset Hub and other parachains to avoid potential loss of funds.
