Archiving notice:

This library is no longer in use and maintenance. All further development related to chainbridge will happen in the new repo. More detailed information about chainbridge-core you can find in its readme or Discussions.

If you already running an old ChainBridge version please consider checking chainbridge-migration scripts that allow migrating to a newer version of chainbridge.

chainbridge-substrate

Substrate implementation for ChainBridge.

This repo contains two pallets:

chainbridge

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

example-pallet

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.

example-erc721

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.
