Circle Internet Financial provides a comprehensive guide on the differences between bridged USDC and native USDC, focusing on the migration process from bridged USDC to native USDC on the Sui Mainnet. Bridged USDC, which is created via third-party applications like Wormhole by locking USDC on one blockchain, contrasts with native USDC issued directly by Circle and backed by highly liquid assets, ensuring a 1:1 redemption for US dollars. The guide emphasizes best practices for user interfaces, recommending clear naming conventions and correct token addresses to differentiate between the two forms of USDC. It highlights the benefits of native USDC, including full backing and compatibility with Circle Mint and API support, which facilitates institutional on/off-ramps. Developers are encouraged to implement swapping mechanisms or use decentralized exchanges for migrating users to native USDC. Additionally, incentives and opportunities for liquidity migration are discussed, alongside methods for accessing native USDC on Sui Mainnet through DeFi protocols and CCTP-enabled bridges. Circle aims to enhance economic accessibility and efficiency globally by transforming money movement.
