Multisig Vaults

A multisig vault splits control of your bitcoin across multiple keys. No single key can move your coins on its own, so one lost device, one hacked laptop, or one compromised person is never enough to lose everything.

How multisig works

Multisig means multiple signatures. You create several keys, say three, and set a quorum, say two. That is a 2-of-3 vault: any two of the three keys must sign to move coins. Each key lives on a separate device in a separate place, so there is no single point of failure.

When multisig is worth it

• Your stack is large enough that a single seed phrase feels fragile. When one backup stands between you and catastrophe, spreading control across keys is worth the setup.
• Shared control. Family members or business partners who must approve together, so no one person can move funds alone.
• Inheritance. Heirs can recover funds without holding a live key today, with a clear, documented path to access later.
• Physical security. Keys in different locations resist theft and coercion, because no single place holds everything needed to move your coins.

Multisig is overkill for small amounts and total beginners. Start with a single-signature hardware wallet, build good backup habits, and graduate to multisig when the stakes justify the complexity.

The multisig wallets worth knowing

Six options, from pure self-custody to assisted services.

Get these five things right

1. Back up the wallet configuration, not just the seeds. A multisig vault needs the extended public keys (the wallet descriptor file). Seeds alone cannot rebuild it.
2. Separate your keys geographically. Different devices, different places.
3. Choose your quorum deliberately. 2-of-3 is the sweet spot for most people; 3-of-5 suits larger or shared setups.
4. Test recovery with a small amount before trusting the vault with your stack.
5. Plan inheritance now. Document where keys and the configuration live, and who gets access under what conditions.

Multisig questions, answered (FAQ)

Is multisig overkill for a beginner?

Usually, yes. Learn single-signature self-custody first: one hardware wallet, one verified backup. Move to multisig when your holdings or your threat model outgrow it.

What happens if I lose one key in a 2-of-3 vault?

Nothing bad. The remaining two keys still meet the quorum. Replace the lost key with a fresh one and move funds to a new vault when convenient.

Can I use hardware wallets for the keys?

Yes, and you should. Each key ideally lives on its own hardware wallet from a different place than the others.

Does multisig cost more in fees?

Slightly. Multisig transactions are larger, so they pay a bit more per transaction. On modern fee rates the difference is small.
