This project implements a Substrate backend for our go-perun framework. It enables go-perun applications to create state-channels on Polkadot by connecting to the Perun Pallet.

If you want to locally develop with this project:
- Clone the repo:
git clone https://github.com/perun-network/perun-polkadot-backend
cd perun-polkadot-backend- Start a local Substrate node with the Perun Pallet installed. See the polkadot node repository for more details.
docker run --rm -p 9944:9944 ghcr.io/perun-network/polkadot-test-node:0.4.0- Run the tests. This step needs a working Go distribution, see go.mod for the required version.
go test -p 1 ./...The tests take a while but should eventually finish successfully. The long testing time results from the block-time of the node. The -p 1 flag is important, since the tests otherwise are started in parallel and mess up the account nonce.
We prepared a demo CLI node to play around with payment channels on substrate chains.
Highly recommended you to check it out 👍
