Unchained multisig wallets are a game-changer for cryptocurrency users, offering a secure and flexible way to manage funds.
A multisig wallet requires multiple signatures to authorize transactions, typically between 2 and 5 signatures, making it virtually impossible for a single person to drain the wallet.
This setup prevents unauthorized transactions and ensures that all parties involved are on the same page.
In an unchained multisig wallet, there is no central authority controlling the funds, allowing for true decentralization and peer-to-peer transactions.
The lack of a central authority also means that users have complete control over their funds and can manage the wallet without relying on a third party.
With an unchained multisig wallet, users can create a custom set of rules and permissions to govern transactions, ensuring that funds are used in a way that aligns with their goals.
What Is a Multisig Wallet?
A multisig wallet is a type of wallet that uses multiple private keys to access cryptocurrency assets.
This setup provides a version of multi-factor authentication, making it especially useful when assets belong to multiple parties in a company or a decentralized autonomous organization (DAO).
With a multisig wallet, you can enjoy added security and control over your assets.
In a multisig wallet, smart contracts determine the access rules when accessing the wallet, ensuring that multiple parties must agree before any transactions can be made.
This collaborative approach to custody is becoming increasingly popular, with companies like Unchained offering similar services.
Setting Up a Multisig Wallet
To get started with an Unchained multisig wallet, you'll need to upload two keys to your Unchained account.
Once your account is approved for Tier 2, you can create a new vault by navigating to the Vaults page and clicking New vault.
Name your vault and select the two keys you uploaded earlier, then review your vault and click Create vault.
You'll then be presented with an overview screen showing your multisig wallet balance, options to Deposit, Withdraw, or Transfer funds, and a balance history.
Requirements

To set up a multisig wallet, you'll need to meet a few key requirements. First and foremost, you'll need an approved Unchained account.
An approved Unchained account is the foundation of your multisig wallet, so make sure you've got one set up before proceeding.
You'll also need a multisig vault set up with hardware devices, which provides an additional layer of security and control over your transactions.
A multisig vault is essentially a secure container that holds your private keys and other sensitive information, and hardware devices add an extra level of protection against unauthorized access.
Finally, you'll need a linked bank account for transactions, which allows you to easily move funds in and out of your multisig wallet.
Here are the specific requirements outlined:
- An approved Unchained account
- A multisig vault set up with hardware devices
- A linked bank account for transactions
Create an Vault
Creating a multisig wallet is a crucial step in securing your Bitcoin investments. You'll need to have two keys uploaded to your Unchained account to proceed.
To create an Unchained vault, navigate to the Vaults page and click New vault. This will initiate the process of setting up your multisig wallet.

You'll be prompted to name your vault, and then select the two keys you uploaded earlier. Review your vault settings to ensure everything is correct.
Once you've completed these steps, click Create vault to finalize the setup process. Your multisig wallet is now live, and you can start using it to manage your Bitcoin investments.
Security and Backup
To secure your Unchained multisig wallet, take the next steps by setting up proper 2 factor authentication and recording an identity verification video.
Achieving the highest levels of security requires diligence and forethought, especially when it comes to securing the physical elements of your vault. Consider using two hardware wallets and two seed phrases, geographically distributed across four secure locations.
Here are the key steps to secure your private key material:
- Set up 2 factor authentication
- Record an identity verification video
- Use two hardware wallets and two seed phrases
- Geographically distribute them across four secure locations
Upload Keys
To upload keys to your Unchained account, sign in and click Keys to view your list of keys. If you're new to Unchained, you won't have any keys yet.

You can add new keys to your account by clicking Upload New Key. This will allow you to add and manage your keys in one place.
All private keys are required for access in threshold signature wallets, which include all three multisig wallet types. This means that if you have a wallet with five signatories, all five keys are needed to validate any transaction.
Back Up Wallet Config File
It's crucial to back up your wallet configuration file to ensure you can recover your funds in case of an emergency. This file is available in the Vault tools menu, where you can choose View next to Wallet configuration file and click Download.
The downloaded file does not include private keys, so it won't put your funds at risk. However, it does include public keys and critical information that's essential for recovering your funds if Unchained's platform is offline or ceases to exist.
Store this file in a safe place, such as a password manager, to keep it secure and easily accessible.
All Keys Required

All keys required for a transaction is a concept that can be a bit confusing at first, but it's actually quite simple. This type of multisig wallet requires all private keys to validate any transaction.
For example, if you have a multisig wallet that requires five private keys, all five keys must be present and signed before a transaction can be made. This eliminates the risk of a single point of failure, where one person has access to all the keys and can compromise the entire wallet.
In other words, all keys required means that no single person has control over your Bitcoin, and even if one key is lost or stolen, the others can still be used to secure your assets.
Here are some examples of multisig wallets that require all keys to validate a transaction:
This approach provides an additional layer of security and ensures that your Bitcoin is protected from unauthorized access.
Multisig Wallet Configurations

Multisig wallets have different configurations depending on the number of keys required for a transaction.
A multisig wallet requires a minimum of two keys to be present for a transaction to occur, making it a more secure option.
The required number of keys for a transaction distinguishes the various types of multisig wallets.
In cases where parties collectively own crypto assets, multisig wallets make it easier to build trust among wallet users.
Types of Multisignature Wallets
There are different types of multisig wallets, and they're distinguished by the required number of keys for a transaction.
The required number of keys for a transaction is what sets each type apart.
In a three-key multisig wallet, two keys are needed to move funds, as seen in the example of Unchained holding one key as a backup for a client's Bitcoin.
Unchained only holds one key, which means they can't move the client's Bitcoin without the other key holder's permission.

One Signature

In a one signature multisig wallet configuration, a single party has full control over the funds.
This means that all decisions regarding the wallet are made by one person, with no need for input from others.
Two parties that trust each other can use a multisig wallet to share funds, but this is not the case in a one signature setup.
One signature wallets are ideal for individuals who want to have complete control over their funds, but may not be suitable for shared financial responsibilities.
Three of Five Signatures
This multisig wallet configuration is a secure way to store your crypto assets. It involves storing four keys in different offline locations, and the fifth remains with the wallet provider or a security company.
You can access your crypto assets if you can access two of the four offline keys. This adds an extra layer of security to your wallet.
Here's a breakdown of how this configuration works:
This setup makes it more difficult for a single person to access your assets, as two keys from different locations are required.
This configuration is ideal for individuals who want to share access to their assets with trusted parties, but still maintain control over their crypto holdings.
Benefits and Risks

Multisig wallets offer enhanced security for Bitcoin investors by requiring multiple signatures for transactions, reducing the risk of single point failure.
Multisig setups distribute control over Bitcoin among multiple keys, eliminating the risk associated with a single key. This is particularly important for investors who have been fortunate enough to get rich off Bitcoin.
A multisig setup is more secure than a single-signature hardware wallet, where the seed phrase becomes a single point of failure.
A three-key multisig vault is a robust security solution, where the investor retains two keys and a third key is held as a backup. This ensures that even if one key is lost or stolen, the Bitcoin remains secure.
Here are the benefits of a multisig setup:
- Reduced risk of single point failure
- Enhanced security for Bitcoin investors
- Maintains investor control over their assets
This balance between security and sovereignty is particularly important for investors who value their independence and autonomy.
Bitcoin Vulnerability Risk
Keeping your Bitcoin on an exchange or in a software wallet is not a good idea, as it leaves you vulnerable to theft.

A single point of failure is a major risk, as someone who gains access to your seed address can compromise your assets.
A multisignature setup is a way to eliminate this single point of failure, requiring multiple signatures to generate a transaction.
This can be a more secure option, but it's essential to understand the importance of a seed phrase and how it's used in this setup.

Are Multisigs Futuristic?
Multisigs are a collaborative custody option, where investors create a three-key vault with one key held by the investor and the other two held by separate parties, such as Unchained.
In a multisig setup, multiple keys are required to move Bitcoin, making it more secure than traditional single-key storage.
With multisigs, investors can have more control over their Bitcoin, as they can set up the vault to require multiple signatures before a transaction can be made.
Unchained's collaborative custody option, for example, allows investors to create a three-key multisignature vault, with two keys held by the investor and one held by Unchained as a backup.
This setup renders Unchained unable to move clients' Bitcoin without the investor's explicit permission, as they only hold one of the three required keys.
