This token represents USD Coin (USDC), which has been transferred from the Solana network onto multiple networks via Portal Bridge (formerly Wormhole Bridge). It is listed separately not only due to the distinct roles played by the networks but also to clarify the responsibility for the bridged token. Since Portal Bridge manages the asset across several chains, the original project is not responsible for issues or vulnerabilities that may arise with the bridged token, such as security breaches or governance changes. This ensures precise tracking and management of assets across different liquidity pools, governance structures, and technical infrastructures in multiple chains and networks.
