To test the ledger integration you can use an asset-hub-polkadot-dev, asset-hub-kusama-dev or asset-hub-westend-dev chain which requires setting up the relay chain and attaching the corresponding Asset Hub as a parachain. For this purpose, zombienet is the preferred choice.

To run in a dev environment:

• Clone and build Polkadot's three binaries: polkadot, polkadot-execute-worker and polkado-prepare-worker, with --features=fast-runtime, in order to decrease the epoch time for development, and copy it into the zombienet folder.

• Download the latest binary for polkadot-parachain into the zombienet folder.

• Setup zombienet by downloading your OS's executable from the latest release into the zombienet directory. Note: For macos users if permission is denied to run the binary you can chmod 755 <file_name> to allow permissions.

• Edit the config.toml file according to your needs.

• If you are on linux:

• • $ yarn
    $ yarn dev-linux
    

• If you are running on macOS:

• • $ yarn
    $ yarn dev-macos
    

• Then on a different terminal:

•   $ yarn start
  

• Select local from the list:

• 

• After setup you must send funds from your relay chain to Polkadot Asset Hub. You can do that in polkadot.js.org/apps .

• Set chain to Local Node under the Development option from the dropdown list.

• On the Developer tab go to RPC calls, choose xcm pallet > teleportAssets.

There are 3 steps to making and executing a multisig call

• First - create a multsig account

  • this only needs to be done if the account is a new account
  • note - this account is not stored on chain

• Second - Create a multisig tx

  • All calls have been abstracted to a Calls class. When you are promted for the call, just write the function name in the class and you should be routed to the proper call (ex. mint)
  • The argument parameters need to be passed in order and in string quotes "" in an array
  • This should generate the call automatically

• Third - Approve a multisig tx

  • This should have similar steps to creating the tx
  • If the threshold is greater than the approvals this will approve the call, if threshold is equal this will approve and fire tx

Troubleshooting

• Signatories out of order - Need to order the passed through signatories

To interact with the ledger first you need to install the Ledger applications for Kusama Asset Hub and Polkadot Asset Hub from Ledger Live.

To use the Ledger just type ledger instead of inputting a mnemonic.
