Pre-Requisites

  • MetaMask and Substrate Wallets.

  • KAR in your Substrate Wallet and other tokens in your MetaMask wallet to pay for transaction fees.

Address Binding

Note there are a few restrictions of the bind feature by design:

  • Binds can only be done between one Substrate and one MetaMask account

  • Neither account can be previously bound to another account. Additionally, binding is final - there is no unbind feature

2) Double check that you are binding the correct accounts because this action cannot be undone. Click Sign.

If you are having trouble connecting your MetMask, you can manually add the Karura network by opening your MetaMask wallet and going to Settings-> Networks -> Add Networks and entering the following information: Network Name: Karura

New RPC URL: https://eth-rpc-karura.aca-api.network/

Chain ID: 686

Block Explorer: https://blockscout.karura.network/

Symbol: KAR

4) You should see that your accounts have been successfully bound!

FAQ

Can I unbind and bind to a new account?

No. Once you bind two accounts together, you cannot unbind them. If you you'd like to use a different Polkadot account or a different Ethereum account, you'll need to create two new wallets.

Do I need to keep both seed phrases?

Yes. Please keep both seed phrases. If you ever need to recover all of your funds, you will need both sets of seed phrases.

Where can I see the MetaMask address linked to my account?

If you've already completed the binding process, click on your account in the upper right hand corner and then hover over the chain icon to see the linked MetaMask address.
