Substrate implementation for ChainBridge.

This repo contains two pallets:

The core bridge logic. This handles voting and execution of proposals, administration of the relayer set and signaling transfers.

This pallet demonstrates how the chainbridge pallet can be integrated in to a substrate chain. It implements calls that can be executed through proposal only and to initiate a basic transfer across the bridge.

This pallet mimics an ERC721 token contract. It allows for minting, burning and transferring of tokens that consist of a token ID (U256) and some metadata (Vec<u8>). This is also integrated into example-pallet to demonstrate how non-fungibles can be transferred across the bridge.
