Welcome

TokenBridge provides data and token transfer capabilities across EVM chains

The TokenBridge allows users to transfer data (e.g. digital asset ownership information) between two chains in the Ethereum ecosystem. Cross-chain bridges provide fast and secure connections between blockchains, creating scalability and connection - interoperability - between Ethereum networks.

TokenBridge operates in several modes depending on the network requirements. A simple UI allows any user to bridge assets to and from active chains.

POA Bridge

Production asset-transfer bridges

The following bridges are fully-functional in production environments:

  • POA Bridge (POA network to Eth Mainnet):The POA Bridge was the first EVM cross-chain production bridge in existence.

  • xDai Bridge (Eth Mainnet to xDai Network): The xDai chain uses the ERC20-to-Native TokenBridge functionality to provide fast, inexpensive and stable transactions.

  • Eth Classic Bridge (Eth Classic to Eth Mainnet): The Eth Classic Bridge connects ETC to ETH, where ETC is available as WETC.

Additional bridges in development include the Arbitrary Message Bridge (AMB) and the Binance Bridge (ETH - BNC) which are actively running in test environments.
