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.
Production asset-transfer bridges include:
POA Bridge (POA network to Eth Mainnet)
xDai Bridge (Eth Mainnet to xDai Network)
Eth Classic Bridge (Eth Classic to Eth Mainnet)
