Setup Apps

Apps is a fork of Polkadot-js/apps UI.

git clone
git checkout page-supersig-new-apps
yarn start

If you want to use docker you just need to run the command:

docker run --rm -it --name supersig-ui -e WS_URL=ws:// -p 80:80 decentration/apps:latest

you can view most of the changes made in supersig in:


Now in order to test the supersig functionality you need a chain that is running supersig, this is what we will setup next.

Setup Supersig Node Template

git clone
git checkout v0.9.28-new
cargo update
cargo build --release
./target/release/node-template --dev

Now in the apps ui, make sure to “switch” to development/local node. This is typically ``.

Voila! you should be up and running.

What to test?
