## The what bridge?

The Omnibridge is a multi-token extension of the [Arbitrary Message Bridge](https://docs.tokenbridge.net/amb-bridge/about-amb-bridge) allowing to transfer ERC-tokens in both directions between the Ethereum Mainnet and Energy Web Chain. It is a lock-mint/burn-unlock bridge, ensuring a 1:1 peg of tokens on both sides.

There are tokens that have their original home on either EWC or Mainnet. The bridge allows them to be used on other chains without them losing any value.

Kudos to the Poanetwork/xDAI team for making this awesome tech open source.
