This token represents Serum (SRM), which has been transferred from the Solana network to multiple networks via the 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 this asset on multiple networks, the original project is not responsible for any 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 within the multiple networks' liquidity pools, governance structures, and technical infrastructure.
