Tokens bridged cross-chain are appended with the "on xDai" or "on BSC". There are instances where bridging across multiple chains creates token names such as "STAKE on xDai on BSC" for example.
Double bridging also can result in multiple instances of the same token on a single chain. For example, USDC can be bridged to xDai from Ethereum and also bridged to xDai from BSC. This results in 2 separate USDC token instances on xDai. These tokens cannot be merged into a single instance after they are minted.
