Interacting with your Tanssi Substrate Appchain Using Talisman


Developers and users of Tanssi Substrate appchains have a variety of options when it comes to wallets. Talisman is a great option, as it provides full native support for both Substrate and Ethereum accounts. This guide focuses on the Substrate API. You can also check out a similar guide for configuring Talisman for use with your Tanssi EVM appchain.

Talisman is a Web3 wallet that natively supports Substrate (Polkadot) and Ethereum accounts. The Talisman wallet browser extension is available on Google Chrome, Brave, and Firefox, and a corresponding asset dashboard is accessible at

This guide takes you through all the necessary steps, from installing Talisman to setting up a wallet, connecting it to your Tanssi Substrate appchain, and sending funds.

Setting Up Talisman

First, download and install the Talisman extension. This guide will first cover creating a new wallet and later address importing an existing one. Review the terms and conditions, then press Get Started.

Connecting Talisman to the Tanssi Dancebox TestNet

Talisman already comes pre-configured with support for the Tanssi Dancebox TestNet. You just need to first ensure that you have enabled support for TestNets on Talisman. Remember that the Tanssi Dancebox TestNet itself is not a appchain; it is the Substrate-based parachain that orchestrates and manages the launch of Tanssi appchains. To configure your Talisman to work with Dancebox, take the following steps:

  1. Open the Talisman extension and click on the Talisman logo
  2. Select Settings
  3. Ensure that Enable testnets is checked

If you have a balance of Dancebox tokens, you'll see your account balance on the homepage of the Talisman wallet. If you don't have a balance of Dancebox tokens, the network will be omitted from your list of assets.

Connecting Talisman to Your Substrate Appchain

To configure Talisman for your Tanssi Substrate appchain, open the Talisman extension and click on the More Options tab. Click on Settings > Networks & Tokens > Manage Networks.

  1. Slide the network slider to Polkadot
  2. Check the Enable testnets box
  3. Press Add Network

On the following page, you'll then be prompted to enter the network details for your Tanssi appchain. For demonstration purposes, the Dancebox TestNet is used here, but you can substitute these details for your own Tanssi appchain. To add your Tanssi appchain to Talisman, take the following steps:

  1. Paste in the RPC URL of your Tanssi appchain. Other parameters will be auto-populated
  2. Optionally, enter the block explorer URL of your Tanssi appchain, if applicable
  3. Check the This is a testnet box if applicable
  4. Press Add Network

Add your Tanssi Appchain Network Details

Connecting to Polkadot.js

To connect your Tanssi Substrate appchain to Polkadot.js Apps, first head to Polkadot.js Apps. In this example, Polkadot.js Apps is connected to the Dancebox TestNet, but you can point Polkadot.js to your Tanssi appchain by clicking on the network dropdown and filling in the WSS endpoint of your Tanssi appchain in the custom endpoint field.

Connect to Polkadot.js Apps

The Talisman extension will prompt you to select the accounts you'd like to use with Polkadot.js Apps. If it doesn't automatically pop up, you can open the Talisman extension and click on the heading at the top. To configure Talisman to correctly interface with your Tanssi appchain on Polkadot.js Apps, you should take the following steps:

  1. Select the Substrate account(s) that you'd like to use with Polkadot.js Apps
  2. Press Connect 1. The value will change depending on the number of accounts you are connecting
