If you want to move your masternode to a new public key (e.g. to a hardware wallet), you will need to send 1,000 Dash in a single transaction to the new address and launch a new masternode. Moving your 1,000 Dash collateral will take your existing masternode offline.
Here are the steps:
Fund a new public key (receive address)
Send exactly 1,000 DASH to a new public key in the wallet of your choice. This will drop your old node offline. Remember the old node will no longer receive reward payments.
Email NODE40 at email@example.com when you are ready to launch a new node. We will credit your account for a month of service.
Launch New Node
From your NODE40 account, launch a masternode using the new public key.
Select one month of service for the payment step. This will allow you to bypass sending us an additional hosting fee.
Remote-start your new masternode
Follow the steps you would normally take to remote-start your masternode. Once the new masternode is running and enabled, we will manually change the renewal date to match the original masternode.
