[Informative] Swapping USDC Across Blockchains Using XDC Bridge

Introduction

Swapping USDC between different blockchains can be a complex task, but with the right tools and guidance, it can be made seamless and efficient. This guide will walk you through the process of transferring USDC from the Arbitrum Sepolia blockchain to the XDC Apothem blockchain using the XDC Bridge and Circle APIs. By following these steps, you can ensure a smooth and secure transfer of your digital assets.

Circle’s Guideline to Create a Bridge

Circle has developed a comprehensive guideline to facilitate the creation of a bridge for USDC across different blockchains. This guide provides detailed instructions on the bridged USDC standard, which ensures that USDC can be securely and efficiently transferred between Ethereum Virtual Machine (EVM)-compatible blockchains.

The guideline covers essential topics such as the architecture of the bridged USDC, the technical standards involved, and the steps required to implement the bridge. For more detailed information, you can access Circle’s guideline on creating a bridge for USDC here: Circle Bridged USDC Standard.

If the XDC network supports native USDC, CCIP enables native crosschain between all chains with native USDC support, is there a reason why bridges are needed separately?
Is it synthetic USDC?
