FAQ

Why is Multi Shield different from any other metal seed phrase storage product?

With Multi Shield you get three stainless steel plates and you divide your seed phrase between them. You require any two of the three to make up your complete seed phrase. This eliminates the single point of vulnerability which you get from any method of storing your complete seed phrase in one location.

Do I get everything I need when I purchase the Multi Shield?

Yes. You will receive three stainless steel plates and one automatic centre punch which you will use to mark out each letter on your plates.

The Multi Shield only allows for 4 letters on each word, but my seed phrase contains words longer than 4 letters. How does this work?

You only need the first four letters of any of your seed phrase words. The way BIP-39 works is that no two words from the list will contain the same first four letters.

My seed phrase has a three letter word. How does this work?

Just enter the three letters only, and leave the fourth square blank. 

Whilst no two words contain the same first four letters, many words contain the same first three letters. For example: 'ACT' and 'ACTION', so for the word 'ACT' you would punch in ACT and then leave the fourth square blank, and for 'ACTION' you would punch in ACTI.

What happens if somebody gains access to my complete seed phrase?

If your seed phrase is compromised and somebody has access to your full seed phrase then they could gain access to all of your funds from the crypto wallet which your seed phrase is a back-up to. You will need to send your funds to a newly created wallet with a new seed phrase.

Can I store all three Multi Shield plates together?

The problem which Multi Shield is trying to solve is that of having a single point of vulnerability or failure. If you store all three shields together and somebody gains access to this one location then they could gain access to your crypto wallet. It is much safer to store your plates separately, then if one location gets compromised you can still access your wallet from the other two shields and the one shield which is compromised provides no access to your wallet.

Where can I hide or store my Multi Shields?

You should store your Multi Shields in a safe and secure place or with people you trust. Even though access cannot be gained with just one shield, you will want to limit the risk of people conspiring to find two of your shields. Should one shield get lost or stolen then you now do not have a back-up.

One example could be that you keep one shield in your possession, keep one with a trusted relative and one in a safety deposit box. Should the relative accidently bin your shield or should the safety deposit box get robbed then your funds are safe and still accessible. 

Should you be abroad and need quick back-up access to a wallet then you could request the rest of your seed phrase from your relative over the phone. As you would only be sending 1/3 of your seed phrase over the phone, this should limit the risk if somebody were to intercept the message. 

Can somebody gain access to my wallet with just one Multi Shield?

No. A hacker would need the full seed phrase to access your wallet. 

How durable is the Multi Shield?

Multi Shields are extremely durable and are made from solid 304 stainless steel, which offers excellent resistance to a wide range of environments and many corrosive media. This is due to its high chromium content (18-20%) and the formation of a passive chromium oxide layer on its surface. This layer protects against oxidation and general corrosion. They shields are water resistant and the melting point is 1400 degrees Celsius. That said, if you will be burying one of your shields outside then we recommend still weatherproofing it (plastic bag etc) for added security.

I have more than one seed phrase and so I need more than one Multi Shield, how will I differentiate between plates?

We suggest using the automatic centre punch to mark either a letter or a number for a particular set. For example, when storing two seed phrases you will need two Multi Shields - which will be two sets of three plates. For your first seed phrase you can mark the letter 'A' on each of the three plates and for the second seed phrase you can mark the letter 'B' on each of the three plates. This way, you may store multiple seed phrases in the same three locations and you will not confuse one from the other.
