Best Bitcoin Multisig Wallets
No single point of failure. That's the whole point. Multisig requires multiple keys to move your Bitcoin, protecting against theft, loss, and $5 wrench attacks. We tested 7 solutions so you don't have to.
What is Multisig?
Here's the short version: multisig (multi-signature) means spending Bitcoin requires approval from multiple keys. Instead of one key that could be lost, stolen, or compromised, you spread control across several keys. Lose one? You're still fine.
How 2-of-3 Multisig Works
Any 2 of your 3 keys can authorize a transaction. Lose one key? You still have two others.
Theft Protection
A thief would need keys from multiple locations. Stealing one? Totally useless.
Loss Resilience
Lose a hardware wallet or forget a password? Remaining keys let you recover.
Inheritance Ready
Give keys to heirs or trustees. Built-in succession, no single point of failure.

Frequently Asked Questions
Quick answers to the questions we get asked most about Bitcoin multisig.
What is multisig and why does it matter?
Multisig (multi-signature) requires multiple private keys to authorize a Bitcoin transaction. A 2-of-3 setup needs any 2 of 3 keys to spend. No single point of failure. If one key is lost, stolen, or compromised, your Bitcoin stays safe.
What multisig setup should I use?
For most people, 2-of-3 is the sweet spot. You keep two keys on separate hardware wallets in different locations, and a third as backup. Sitting on a bigger stack? Look into 3-of-5 with a collaborative custody service like Casa.
Can I set up multisig for free?
Yes. Sparrow Wallet, Specter Desktop, Caravan, and Electrum are all free, open-source multisig coordinators. Paid services like Casa and Unchained add convenience, hand-holding, and recovery help if something goes wrong.
What happens if I lose one of my keys?
In a 2-of-3 setup, losing one key isn't a disaster. You still have two remaining keys to move your funds to a new wallet. That's the whole point of multisig over a single-key setup.
Should I use a managed service or set up my own multisig?
It depends on how hands-on you want to be. Casa and Unchained make it easy and offer recovery help, but they charge fees and hold one of your keys. DIY multisig with Sparrow or Specter costs nothing, but you need the technical chops and a solid backup plan.
How does multisig work with inheritance?
You can combine multisig with time-locked transactions for inheritance. Casa and Unchained both offer inheritance protocols where recovery keys activate after a set period of inactivity, so your heirs can actually access the funds.
Do I need multiple hardware wallets for multisig?
Yes. For real security, each key should live on a separate hardware wallet from a different manufacturer. If one brand has a firmware bug, you're still covered. A typical 2-of-3 setup uses something like a Ledger, a Trezor, and a Coldcard.
Is multisig overkill for small amounts?
Honestly? For amounts under a few thousand dollars, a single hardware wallet with a good backup is plenty. Multisig adds complexity that probably isn't worth it for smaller stacks. Once your Bitcoin becomes life-changing money, that's when multisig starts making sense.
