6th key

Casa's Diamond membership features an advanced 3-of-5 multisig key manager by default. This is a wallet with five keys, which requires any three of them be used together to send funds. 

You can optionally enable a wallet with a 6th key, which creates a 3-of-6 multisig keyset.

Why would I add a 6th key?

The 6th key offers more redundancy for your Key Shield. It could be stored separately from your other keys, perhaps in a different geographic region (if yours is prone to natural disasters), or simply be an extra key that you can use to sign transactions in the event that your Office or Safe Key is not accessible. 

You may also wish to use a 6th key along with Diamond's Team Signing feature, for additional flexibility in key distribution to other members of your team or family.

Creating your 3-of-6 keyset

To set up your 3-of-6 Key Shield, tap on the middle icon in your Key Shield, then tap the three dots at the top right corner to open advanced options.

Press "Switch to Six Key Setup" and click "Confirm and Continue" to confirm.


Choose the hardware device you want to use to set up the 6th Key and click "Let's Go" and "Send Email." You will receive an email with a link to connect your new key with the 3-of-6 Key Shield.

Go ahead and open your email on your computer, connect the hardware device to your computer, and follow the instructions in the email to link the device with the Key Shield.


We recommend that this key be stored in a separate geographic location from your other keys.

Transferring funds to the new 6-key wallet

Adding a 6th key to your Key Shield will create a brand new wallet. This means that you will need to transfer the funds from the old 3-of-5 Key Shield to the new 3-of-6 Key Shield in an on-blockchain transfer.

You will see a "Funds Transfer Required" button at the bottom of the main screen. Tap that button and choose "Continue Guided Recovery" to start the transaction process. 

Remember that you will need to sign this transaction with three keys from the original 3-of-5 Key Shield.


Going back to 5-key Key Shield

You can always go back to the standard 5-key Key Shield if the 6-key setup isn't right for you.

Follow the same steps you did to add a 6th key and choose the option "Switch to Five Key Setup" and follow the app's instructions.

Once again, this will create a brand new wallet. You will need to transfer the funds from the old 3-of-6 Key Shield to the new 3-of-5 Key Shield in an on-blockchain transfer.


Once you complete this step, your funds will be back in a 5-key Key Shield!
