xDai TokenBridges provide multi-chain compatibility and interoperability
  • 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.

For In-depth bridge specific documentation, please see the TokenBridge Docs.

With Multi-chain bridging, there is a possibility that multiple instances of the same underlying token 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 can result in 2 separate USDT token instances on xDai. These tokens cannot be merged into a single instance once they are minted.

Tether on xDai: 1 is bridged from ETH, the other from BSC

If you bridge and do not see the expected liquidity, for example in HoneySwap, know that there may be 2 instances of the same token on xDai. You will see a tag letting you know in an instance was bridged from Ethereum or BSC.

We are working on steps to address this issue in a decentralized manner without requiring prior approval to bridge. Look for more details soon.
