Creating a Multi-Signature Wallet in Mist
The Mist Ethereum wallet has an option to secure your wallet balance with a multisig wallet. The advantage of
using a multisig wallet is that it requires authorization from more than one account to withdrawal larger amounts
from your balance. Before you can create a multisig wallet, you’ll need to create more than one account.
It’s very easy to create account files in Mist. In the ‘Accounts’ section click ‘Add Account’. Pick a strong yet
easy-to-remember password (remember there is no password recovery option), confirm it, and your account is
created. Create at least 2 accounts. Secondary accounts can be created on separate computers running Mist if you
prefer (and theoretically make your multisig more secure doing it this way). You only need the public keys (your
deposit addresses) of your secondary accounts when creating the multisig wallet (copy/paste them, do not ever
type them by hand). Your primary account will be needed to create the multisig wallet contract, so it must be on
the computer you are creating the multisig wallet on.
Now that you have your accounts setup, be safe and back them up (if your computer crashes, you will lose your
balance if you do not have a backup). Click ‘Backup’ in the top menu. Choose the ‘keystore’ folder, opposite-click
on it / choose ‘copy’ (do NOT choose ‘cut’, that would be very bad). Navigate to your desktop, opposite-click in
a blank area and choose ‘paste’. You may want to rename this new copy of the ‘keystore’ folder to something like
‘Ethereum-keystore-backup-year-month-day’ so you have quick recognition of it later. At this point you can then
add the folder contents to a zip / rar file (and even password-protect the archive with another strong yet easy-toremember
password if backing up online), copy it to a USB Drive, burn it to a CD / DVD, or upload it to online
storage (Dropbox / Google Drive / etc).
You now should add approximately no less than 0.02 ETH to your primary account (the account you will initiate
creation of a multisig wallet with). This is required for the transaction fee when you create the multisig wallet
contract. An additional 1 ETH (or more) is also needed, because Mist currently requires this to assure wallet
contract transactions have enough ‘gas’ to execute properly...so no less than about 1.02 ETH total for starters.
You will be entering the full addresses of all the accounts you are attaching to this multisig wallet, when you create
it. I recommend copying / pasting each address into a plain text editor (notepad / kedit / etc), after going to each
account’s details page in Mist, and choosing ‘copy address’ from the right-side column of buttons. Never type
an address by hand, or you run a very high risk of typos and could lose your balance sending transactions to the
wrong address.
