                ~2020.1 Galaxy Attestation
              
          
    Here are the instructions for signing an attestation for your planet on behalf of your galaxy:

Go to https://app.mycrypto.com/sign-message
Sign in with the ETH address for either your voting proxy (if you have one set) or your ownership key
If you're not using a Ledger, go to (4). If you are using a Ledger, you’ll need to change the default derivation path that MyCrypto uses. Follow these steps to select the correct one:


Click the drop down arrow next to “address”
Scroll down to the bottom, and select “custom”
Enter the following: m/44'/60'/0'/1
This should sort your public addresses, such that the one you’re using is ranked first.
Unlock the address you’re using to hold your ship
