xDai Bridge: Bridge from Ethereum to the xDai network designed for the xDai native token. Convert Dai to xDai and bridge xDai to Dai on Ethereum.
Ethereum Omnibridge: Bridge ERC20 tokens between Ethereum and xDai.
Binance Smart Chain OmniBridge: Bridge ERC20s between BSC and xDai. Provides beta access to inexpensive interoperability.
With multi-chain bridging, there is a possibility that multiple instances of an underlying asset can be created on a single chain.
For example, USDT can be bridged to xDai from Ethereum and also bridged to xDai from BSC. This results in 2 separate USDT token instances on xDai. These tokens cannot be merged into a single instance once they are minted.
A suffix is added to the token name in BlockScout, specifying the origin chain of a bridged token (ie. from Ethereum, from BSC etc). Tags indicate a token is bridged, and which chain the token is bridged from. Users can click View Original Token to view the token on the chain of origin.
