In this article we'll cover how to set up and use a shared (multisig) Bitcoin wallet in the Bitcoin.com Wallet app. If you don't know what a shared wallet is, you may want to start with this article. We've also compiled a list of shared wallet use cases.
Shared wallets can be created using many desktop and mobile wallet apps. Let’s take a look at how to do it in the Bitcoin.com Wallet, the fully non-custodial crypto wallet trusted by millions. We are going to set up a Bitcoin (BTC) shared wallet:
On the next screen, you’ll set up your wallet.
Enter the asset type (Bitcoin - BTC).
Decide the number of approvals and participants.
Enter the wallet name (eg. My Family Shared Wallet).
Enter your name (this is the name that will be seen by the shared wallet participants).
Tap continue.
After you’ve set up your shared wallet (see above), you’ll be prompted to invite participants. There are two ways to invite participants:
Ask them to scan the shared wallet’s QR code.
Tap the SHARE button and send them a link to the wallet.
There are two ways to join a shared wallet:
Scan the QR code provided by the wallet creator (tap the scan button at the top-right of the app’s home screen).
Tap the shared wallet link sent to you by the wallet creator.
You’ll be prompted to enter your name. This is the name that other wallet participants will see you as. Finally, tap JOIN to complete the process.
A shared wallet must have a minimum of 2 participants, with a maximum of 6. There is a minimum of 1 approval and a maximum of 6. So, a 1-of-2 all the way up to a 6-of-6 wallet is possible.
Bitcoin (BTC) and Bitcoin Cash (BCH).
Don’t worry, your remaining funds are still there. While a transaction request is waiting to be approved or declined, available funds are locked. When funds are locked, we show a 0 balance. When the transaction request is approved or declined, your funds will unlock and your balance will be shown again.
The creator of a transaction request can use the delete request action to cancel the transaction and unlock funds.
Before a transaction is broadcasted to the public network, it requires a certain number of approvals, based on the configuration of your shared wallet. For example, a 2-of-3 wallet requires 2 approvals before being broadcasted.
Yes, kind of. A transaction request represents the initiation of an on-chain transaction. Before the transaction is broadcast to the blockchain, it first must get enough approvals based on the configuration of the shared wallet. Once the proper number of approvals is reached, the transaction will be automatically broadcasted.
Yes, as long as you are the creator of the request and it is still in the pending state, you can delete a request. All funds locked will be freed and made available to your wallet.
In short, the public key, or the “address,” is same for all participants, but each participant gets their own unique “private key” (seed/recovery phase).
Technically, when a shared wallet is created, all participants are at first assigned their own unique public and private key pair. Once all participants have joined the wallet, a single common public key (aka “address”) is generated and displayed to all participants. This is the address that participants can provide when, for example, requesting a payment.
Unlike "standard" Bitcoin wallets, shared wallets must be manually backed up. For most people, the best way to manually back up a wallet is to write down the wallet's recovery phrase (also known as a seed phrase) on a piece of paper and store that paper somewhere safe.
Here's how to find your shared wallet's recovery phrase in the Bitcoin.com Wallet:
Method 1:
From the home screen, tap on the shared wallet.
Tap the menu button in the top right.
Select "Show my recovery phrase."
Method 2:
