For clear data distinction, this token, initially issued as USDD and bridged onto the Arbitrum network by Arbitrum Bridge, is listed under the alternative ticker AUSDD. This helps accurately identify and differentiate it from the mainnet asset. The separation of tokens is necessary not only due to the distinct roles played by the networks but also to clarify the responsibility for the bridged token. Since Arbitrum Bridge manages this asset on the Arbitrum network, 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 Arbitrum network's liquidity pools, governance structures, and technical infrastructure.
