Circle Internet Financial provides a detailed guide on understanding the differences between bridged USDC and native USDC, focusing on migration best practices from bridged USDC to native USDC on Starknet. Bridged USDC is a synthetic form created when USDC is locked in a smart contract on one blockchain and minted on another through a third-party application, while native USDC is officially issued by Circle, backed by highly liquid assets, and offers a seamless 1:1 redemption with U.S. dollars. The guide emphasizes the importance of transitioning to native USDC for enhanced liquidity and compatibility, offering strategies like using DeFi protocols such as StarkGate, leveraging the Cross-Chain Transfer Protocol (CCTP), and engaging with the Starknet Foundation for liquidity migration opportunities. Developers are encouraged to ensure clear differentiation in UI/UX between bridged and native USDC to avoid user confusion, with native USDC being positioned as the preferred option for transactions due to its stability and direct support from Circle.
