As technical director on the Concierge crew at Unchained, I’ve fielded numerous consumer questions on bitcoin multisig. When you’re simply starting to know the advantages of multisig and the way it works in a collaborative custody context, I hope these ten suggestions will deal with a few of your questions.
Bitcoin doesn’t reside in your gadget
The phrase {hardware} pockets may make it appear to be your bitcoin reside contained in the pockets itself, however that’s not the case—bitcoin isn’t in your gadget in any respect. Really, your pockets generates and shops your keys solely. Your pockets additionally makes accessing the keys user-friendly by both plugging your gadget right into a general-purpose pc or sharing info along with your pc by way of a microSD card.
So the place does bitcoin reside, then? The bitcoin blockchain is a ledger that retains monitor of each transaction that has ever occurred and the balances of each deal with on the community. As an alternative of storing your bitcoin, your {hardware} pockets protects and shops the keys used to unlock—or spend—bitcoin from these addresses.
You may restore your seed phrase to a different {hardware} pockets
If you arrange a bitcoin {hardware} pockets that respects greatest present practices, try to be prompted to again up your pockets utilizing 12 or 24 phrases, usually on a slip of paper that the producer suggests you defend in case one thing occurs to your pockets. These 12 or 24 phrases are your seed phrase, as established in Bitcoin Enchancment Proposal 39, or BIP39.
Your seed phrase is just like the “key to the fort,” it incorporates the whole lot you want to recuperate and use a key to the entire addresses protected by the seed phrase.
The great factor about BIP39 seed phrases is that they’re interoperable amongst {hardware} wallets that help the usual, which implies you’ll be able to recuperate your bitcoin pockets backup (seed phrase) to a different model of {hardware} pockets. When you initially arrange your bitcoin pockets on a Trezor and wish to transfer to a Coldcard, it’s so simple as importing these 12 or 24 phrases.

You don’t want your {hardware} pockets with you to obtain
With bodily money, it’s important to be bodily current to trustlessly and securely transact with one other celebration. Bitcoin fixes this for the digital world. If you wish to obtain bitcoin however don’t have your {hardware} pockets at hand, you’ll be able to nonetheless have a fee despatched to the suitable deal with.
As talked about above, bitcoin doesn’t reside in your {hardware} pockets; it lives on the bitcoin blockchain. For that cause, so long as you or another person sends bitcoin to an deal with that you simply maintain the non-public keys to manage, you’ll at all times be capable of transfer these funds no matter whether or not you’ve gotten bodily entry to your gadget. If bitcoin is shipped to an deal with you already know you management, it should arrive completely high quality within the background with out your involvement.
What this implies for you: When you create a multisig pockets and retailer your {hardware} wallets or seed phrases in safe places, you don’t have to have bodily entry to them to deposit funds.
A tool used as a key in multisig can nonetheless be used as a singlesig pockets
Multisig includes developing a multisig pockets utilizing the general public keys of a number of units, every of which may additionally function a standalone singlesig pockets with none points. If you create a multisig pockets following the rising customary processes, the preexisting singlesig counterparts do not know the multisig pockets exists.
You may consider it as a bunch e mail deal with that forwards to a number of particular person e mail addresses.
Which means, in case you needed, you may retailer smaller quantities of bitcoin on a singlesig pockets—all whereas protecting your main wealth in a multisig pockets constructed utilizing that gadget as one of many keys.
Affirm your multisig deposit deal with
Bitcoin transactions are utterly irreversible, which implies in case you ship your bitcoin to the incorrect deal with, it may be misplaced completely. Fortunately, you should utilize {hardware} wallets to examine your multisig bitcoin deal with on the gadget earlier than sending funds.
Checking your deal with in your gadget confirms three issues:
that the deal with was constructed accurately (i.e. that it’s 2-of-3 multisig, for instance, and never 2-of-5 the place an attacker has added two keys and truly controls the funds)that the pc you’re engaged on isn’t compromised with malware that finds and replaces bitcoin addresses with an attacker’s deal with, andthat your gadget holds a key to the deal with.
Checking the deal with in your gadget needs to be finished earlier than sending significant quantities of funds to any deal with, whether or not singlesig or multisig. As of this writing, Trezor and Coldcard help checking multisig deposit addresses within the Unchained platform.

You don’t want your units bodily collectively to signal
With multisig, you don’t have to have all of your keys in the identical place on the identical time to spend bitcoin. Meaning you’ll be able to signal a transaction in Austin with one key and signal a day later in Dallas with the opposite. The transaction can solely be broadcast in any case the mandatory signatures have been collected (two in a 2-of-3 multisig scheme, for instance).
It is a vital benefit over different bitcoin custody fashions like Shamir’s Secret Sharing Scheme, which lets you distribute management over your bitcoin non-public key by splitting it into a number of components (secrets and techniques), however requires all components to be current on the identical time to recompile a single key and writer a transaction.
You may make a mistake in multisig and nonetheless recuperate your funds
In all bitcoin multisig setups the place m (the variety of keys required to signal) is lower than n (the full variety of keys within the quorum), you’re protected against single factors of failure and may nonetheless recuperate your funds within the case that a number of essential gadgets are misplaced, stolen or in any other case compromised.
There are situations in 2-of-3 multisig (with a collaborative custody companion like Unchained holding the third key), the place as many as three gadgets may very well be compromised earlier than it turns into inconceivable to recuperate your funds.
Regardless that fault-tolerance in multisig supplies peace of thoughts, all of those situations ought to nonetheless be protected towards in any respect prices by following seed phrase and {hardware} pockets storage greatest practices, and it is best to at all times regain full management as quickly as doable within the occasion that any of your essential gadgets are misplaced or compromised. And that leads us to quantity eight…

When utilizing bitcoin multisig, in case you ever lose a pockets or misplace a seed phrase, it’s vital to exchange this key in your multisig m-of-n scheme. You are able to do this with any of the favored multisig wallets.
Even when a single compromised key doesn’t alone jeopardize your funds in most typical multisig m-of-n schemes, changing a compromised key will be certain that you regain full management over your funds and remove the chance that the important thing may ever be used towards you sooner or later.

As we talked about in quantity 4 on this listing, utilizing your {hardware} wallets/seed phrases for each a singlesig pockets and to assemble a multisig pockets doesn’t trigger any points. Equally, utilizing your {hardware} wallets/seed phrases for multiple multisig pockets doesn’t trigger a battle amongst these wallets so long as you aren’t utilizing the identical prolonged public keys (xpubs). That is usually represented as a a number of accounts function in most bitcoin wallets.
{Hardware} wallets let you use totally different xpubs from totally different derivation paths, which is a technical means of claiming a special set of bitcoin keys in your {hardware} pockets generated by the identical 12- or 24-word seed phrase.

Possibly even a mortgage vault as effectively!
