This guide is intended to help with the Chainbridge integration to Polygon Edge. It walks through the setup of a bridge between a running Polygon PoS (Mumbai testnet) and a local Polygon Edge network.
In this guide, you will run Polygon Edge nodes, a ChainBridge relayer (more about it here), and the cb-sol-cli tool, which is a CLI tool to deploy contracts locally, registering resource, and changing settings for the bridge (you can check this too). The following environments are required before starting the setup:
- Go: >= 1.17
- Node.js >= 16.13.0
In addition, you will need to clone the following repositories with the versions to run some applications.
- Polygon Edge: on the
- ChainBridge: v1.1.5
