The best hardware wallets for a multisig setup are Trezor, Coldcard, Blockstream Jade, Bitbox02, and Bitkey. Users strongly recommend mixing different brands in a single setup to prevent a single vendor from compromising your funds.
A multivendor setup means buying devices from separate manufacturers. If one company has a vulnerability, your bitcoin remains safe because the other keys are still required to authorize a transaction. You will need to carefully manage private keys, public keys, and your wallet descriptor.
Keep in mind that multisig transactions are larger in size and incur higher network fees than standard transactions. Most users advise against adding a passphrase to a 2-of-3 setup because it adds unnecessary complexity for very little extra security benefit.
Top Wallet Options
TrezorKnown for ease of use and a long history in the market.
ColdcardProvides air-gapped security and advanced features like dice roll seed generation.
Blockstream JadeAn affordable and user-friendly device that pairs well with others.
Bitbox02Frequently used in multivendor setups alongside Coldcard or SeedSigner.
BitkeyOffers easy recovery and inheritance options, though inheritance requires a second device.
Recommended Hardware Wallets for Multisig
Trezor: Many Users recommend Trezor for multisig setups, citing its ease of use and long-standing presence in the market. "Trezor along with strong passphrase for me".
Coldcard: Coldcard is often suggested for its air-gapped capabilities and strong security features, though some users note it can be more complex for beginners. "Coldcard is technically still safe if you use(d) dice rolls to generate the seed.".
Blockstream Jade: Users mention Blockstream Jade as an affordable and user-friendly option for multisig, with some suggesting combining it with other wallets like Coldcard. "x2 blockstream jades.".
Bitbox02: This hardware wallet is recommended for multivendor multisig setups, often paired with Coldcard or SeedSigner. "Multivendor multisig 2of3 : Coldcard Bitbox02 Then something like Seedsigner or Jade".
Bitkey: Some Users find Bitkey user-friendly for multisig, highlighting its recovery and inheritance features, though noting a need for a second Bitkey for inheritance and potential counterparty risk. "I use Bitkey. So far so good. Only downside is that you need a second Bitkey for inheritance".
Multisig Setup Best Practices
Diversify Vendors: Use hardware wallets from different manufacturers to avoid a single point of failure if one vendor has a vulnerability. "The idea of multi-vendor setup is to eliminate the chance of one bad vendor causing you a loss of all funds.".
Understand Complexity: Multisig increases security but also adds operational complexity, requiring careful management of private keys, public keys (XPUBs), and wallet descriptors. "Biggest pitfall of multisig, to spend from an m of n wallet, you need m private keys and all n public keys (plus a passphrase, if you set one up).".
Backup Wallet Descriptors: Always back up your multisig wallet descriptor, which contains crucial information like derivation paths and XPUBs, as losing it can complicate recovery even if you have the keys. "You have to backup : All of your private 12-24 words mnemonics AND All of your cosigners' XPUBs Ideally your multisig wallet descriptor (wallets like Specter can export this as a .PDF for you)".
Considerations for Multisig
Passphrases: Most Users advise against using passphrases in addition to a 2-of-3 multisig setup, as it adds unnecessary complexity for little extra benefit. "Personally I wouldn't use a passphrase in addition to a 2-3 multisig. That is added complexity for little benefit.".
Transaction Fees: Multisig transactions are typically larger and thus incur higher fees compared to single-signature transactions. "Multisig transactions have more fees as well. They are simply bigger.".
Are you planning to use a 2-of-3 multisig setup with different hardware wallet brands?
Bottom line
To secure your Bitcoin with multisig, Users frequently recommend using a combination of different hardware wallets from various manufacturers to mitigate risks associated with a single vendor.
FAQ
What is a multivendor multisig setup?
It is a security practice where you use hardware wallets from different manufacturers to secure your bitcoin. This eliminates the chance of one bad vendor causing a total loss of funds.
Is Coldcard a good hardware wallet for multisig?
Yes, Coldcard is often suggested for its air-gapped capabilities and strong security features. Some users use physical dice rolls to generate their seed phrase directly on the device.
Do I need to back up my multisig wallet descriptor?
Yes, you must back up your wallet descriptor along with all your private word phrases and cosigner public keys. Losing this information makes recovery extremely difficult even if you still have your physical keys.
Should I use a passphrase with a 2-of-3 multisig setup?
Most users advise against it. Adding a passphrase to a 2-of-3 multisig setup adds operational complexity for very little practical benefit.
Are multisig transaction fees higher?
Yes, multisig transactions are larger in data size than single-signature transactions. Because they take up more space on the blockchain, they cost more in network fees.
