What Is a Multisig Wallet?

The world of cryptocurrency is still very much like the Wild West, not just in terms of price volatility but also regarding security. Holding digital assets is still very risky, from forgetting your private keys to hacks that steal billions of dollars. This is why the question “What is a multisig wallet?” is one that is very relevant and important, and often searched for online.

Consider that in 2022 alone, hackers managed to steal over $3.8 billion in crypto. Most of this was done by defeating wallet or protocol security measures.

This is where multisig wallets or multisignature wallets come in. These wallets are like shared vaults and offer better security by requiring multiple approvals for every transaction.

In this article, I’ll take a look at what a multisig wallet is, how they work, why you should care, and what you need to know if you are considering using one. Whether you are a solo investor or part of a DAO managing community funds, understanding multisig could prove vital.

What Is a Multisig Wallet?

A multisig wallet or multisignature wallet is a type of crypto wallet that requires two or more private keys to approve and execute a transaction. Normally, wallets require only a single private key to move funds.

A useful analogy: It works like a joint bank account or safety deposit box that needs more than one key to open.

In blockchain terms, this kind of setup is often referred to as M-of-N. For instance, a 2-of-3 wallet means three people have keys, but only two are needed to authenticate a transaction.

Multisig wallets are particularly useful for teams, DAOs, and anyone who does not want a single point of failure in their crypto security.

How Do Multisig Wallets Work?

At the core of a multisignature wallet is a very simple idea: instead of relying on one private key, you need multiple keys to authorize a transaction.

What is a multisig wallet transaction process?

1. A transaction is created and broadcast to the network.
2. The transaction remains pending until the required number of valid signatures are submitted, say, 2 of 3. 3: Once this is done, the transaction is validated and executed.

Use Cases of Multisignature Wallets

What is a multisig wallet in terms of its real-world use cases?

Personal Security
An individual investor using a 2-of-3 setup with keys in different devices could get a phone/laptop hacked but still not lose his funds.

Business and Team Wallets
Multisig wallets have found favor with startups, foundations, etc., i.e., teams that hold collective responsibility over funds. The use of such wallets prevents a single person from performing transactions on their own. For example, a 3-of-5 setup could be used in such cases.

Escrow and Trustless Transactions
Multisignature wallets are also ideal for P2P deals. For instance, in a 2-of-3 setup, the buyer and seller sign off on regular transactions. In case of disputes, the 2nd signature becomes the responsibility of a third party, like an escrow agent, who steps in to resolve any issues.

DAOs and Community Governance
Many DAOs use multisig wallets to handle their treasuries. This helps to ensure that spending decisions are always made collectively, in line with DAO principles.

Shared control is crucial in crypto due to its decentralized nature. In such cases, trust is derived from the code and not from authority or relationships.

Advantages of Multisig Wallets

What is a multisig wallet in terms of its advantages?

Why do users choose to use multisignature wallets despite it being more complex to set up and use? This is because the best multisig wallets offer benefits that far outweigh the complexity. Here are the advantages:

Better Security
This is perhaps the biggest draw of multisig wallets. The very fact that multiple keys are required makes hacking that much more difficult. Think of it as an MFA (multi-factor authentication) system for your wallet.

Shared Control
For those in teams or organizations, multisignature wallets make sure that every decision is made collectively. This helps to decrease the likelihood of fraud, theft, or even plain old mismanagement.

Preventing Human Error
In regular wallets, if the key or device is lost, then the funds are likely to become unrecoverable. In the case of multisignature wallets, even if one key is lost, the others can still recover the assets, a fail-safe that normal wallets lack.

Decentralized Decision-Making
The use of multisig wallets in DAO treasuries or startup funds helps build trust by making it necessary for multiple parties to approve every financial move.

Limitations & Challenges

What is a multisig wallet in terms of its disadvantages and limitations?

Multisignature wallets are excellent when it comes to security, but they can be inconvenient and complicated to use. Here are some common disadvantages:

Complicated Setup
This is the usual gripe of beginners trying to use multisignature wallets. Regular wallets usually only need to be installed and work immediately. On the other hand, multisig wallets often require some manual configuring, other key holders need to be available, and you may need some coding knowledge as well.

In addition, your options for multisig are limited in terms of wallets and exchanges.

Losing Your Keys
If you lose most of your keys and/or recovery phrases, the wallet could be lost permanently. There is no “forgot password” option here, like in centralized platforms. This means users have the additional burden of having to plan the distribution of multiple keys carefully and also have a recovery process in place.

Limited Platform Support
If you want to use a multisignature wallet, it is crucial to know that not all cryptos or wallets support it. For instance, Bitcoin supports it through Electrum and Ethereum through Gnosis Safe, but many other blockchains do not have such features.

Also, even if you find the best multisig wallet, it does not mean that it will work smoothly with DeFi apps or exchanges that are built on the same blockchain.

Smart Contract Risks
Multisig is often achieved through smart contracts, especially on chains like Ethereum. If the code in the contract itself is flawed and buggy, then it naturally puts your wallet at risk. Preventing this requires good code auditing.

To sum up, choosing multisignature wallets means choosing added protection, control, and the need for careful planning over ease of use. For many, that is a good deal.

Popular Multisig Wallet Providers

So after all that, if you think you want to go the multisig way and want to find the best multisig wallet for your needs, here are some of the most popular and trusted multisig wallet providers:

Gnosis Safe (now Safe)
Arguably the best multisig wallet for Ethereum, Gnosis Safe has recently rebranded to Safe. It is, hands down, the most popular multisig wallet for Ethereum and is widely used by DAOs, DeFi platforms, and some of the biggest crypto companies to manage their treasuries.

Safe also lets users set highly customizable permissions, giving them a great degree of control over security beyond just having multiple keys. It also works great with Web3 dApps.

The Future of Multisignature Wallets

What is a multisig wallet in terms of the future?

As things stand, multisignature wallets are well-established as providing excellent protection for crypto assets. In the years to come, with advancements in Web3, the way we secure our cryptocurrencies will also evolve. Let us take a look.
Innovations In Smart Contracts
We can already see that programmable logic is being used to enhance the best multisig wallets. In the future, they may work with smart contracts to support custom permissions, time-locked transactions, and even the use of AI to provide risk analysis.

Social Recovery and Account Abstraction
Ethereum is currently pushing hard for account abstraction. This could soon result in multisignature wallets that feature social recovery options, i.e., trusted friends, family members, etc, could help you recover access if you lose your keys. Multisig wallets look set to become much more user-friendly in the future.

Cross-Chain and Interoperable Solutions
More and more blockchains, each with its use cases and technology, are becoming mainstream, and this trend looks set to continue. This means that in the future, the best multisig wallets will be those that can manage assets on different chains from a single interface.

This is where the multisig space is headed and options like Safe are already looking into multichain deployments.

Better UX and Mainstream Adoption
The complexity associated with using multisignature wallets is perhaps the biggest hurdle in the way of its widespread adoption. The future promises to bring improvements in this regard, with better interfaces, easier onboarding, and integration with popular wallets like MetaMask. This would likely result in multisig becoming par for the course, rather than being viewed as a niche power tool.

To Sum Up

Crypto investors know that a single key that is lost or stolen can cost millions. Multisignature wallets give users the ability to require multiple authorizations for every transaction, giving them a simple yet effective way to safeguard their assets.

You could be an individual who has invested his savings in digital assets, a large business managing shared funds, or a DAO looking after a community treasury. In all cases, multisig wallets give their users peace of mind by reducing the risk of human error, insider theft, and single points of failure issues.

Yes, they can be more complicated to set up and use, but the future looks very promising. The growing use of smart contracts, social recovery, and cross-chain capabilities looks all set to reduce the limitations associated with multisig wallets.

So, what is a multisig wallet? It is the manifestation of the fact that in crypto, the best security is not about trusting someone; it’s about trusting the code.
