You can also use letter and number stamps with a hammer or engraving drill to mark extra information beside your seed pharse on any Coinplate.

Is Coinplate BIP39 Compatible?

Yes, all Coinplates are 100% BIP39 compatible. Every type of Coinplate has the ability to store 24 seed words which can be one 24 words seed phrase or two 12 words seed phrases.
Coinplates are super easy to use and read – you can be sure that you will be able to read your recovery phrase after a decade or longer.
Other solutions that use binary or number conversion might make reading your seed words difficult after few years.

You can use Coinplate to safely store and backup seed words for any BIP39 compatible wallets including hardware wallets like Ledger (Nano and X), Trezor, Keepkey and other as well software wallets like MetaMask, MyEtherWallet and many others including coin proprietary wallets.

It is possible to use Coinplate also with other seed phrase standards.

Are the 4 first letters of seed word enough?

Yes, BIP39 protocol is made of 2048 carefully chosen words. The way BIP39 protocol is designed guarantees that you can identify your seed words with just 4 first letters of each word on the list.
Quoting BIP39 documentation:

“…wordlist has the following characteristics:

    a) smart selection of words
   – the wordlist is created in such a way that it’s enough to type the first four
     letters to unambiguously identify the word

    b) similar words avoided
   – word pairs like “build” and “built”, “woman” and “women”, or “quick” and “quickly”
     not only make remembering the sentence difficult but are also more error prone and more difficult to guess

This guarantees you will not mistake your seed words.

How can I secure my additional passphrase with Coinplate?

You can use additional Coinplate to store your passphrase. We do not advice storing passphrase together with a seed phrase for security reasons.
If your passphrase is just letters you can use any type of Coinplate, if you have numbers or symbols in your passphrase you should use Coinplate Punch and appropriate stamps. 

How sturdy is the Coinplate?

We went overboard with Coinplate design and made it excessively durable. Coinplate weights over 2.5 lbs or 1 kg and is made with heavy-duty Stainless Steel. Both plates are 5mm or 3/16″ thick (gauge 6) and are joined together with stainless steel bolts to form a steel slab 10mm or 3/8” thick. This is much thicker than our competitors and we make it that way so you can sleep safe. Coinplates should survive getting run over by a truck as well as being shot with handguns. There is no reason to do that but that means it will survive massive drops or being crushed by a house rubble in case of disaster.

Coinplate is 100% Stainless Steel. Plates and bolts are made of AISI 304/1.4301/A2 stainless steel type. This type of stainless steel is exceptionally corrosion resistant and can last many decades. Coinplate is fireproof with melting temperature around 1.450°C/2.650°F while house fires reach up to 850°C/1.500°F.  We use either German or other European Stainless Steel.

How can I hide Coinplate?

Coinplate features additional holes which you can use to easily attach it with screws to the furniture, ceiling, drywall, stairs, wooden beams or any other hard to reach places in your house and office. This is unique Coinplate feature not seen in competitive solutions. Included you will find a set of wood screws but you can use any suitable screws. Coinplate is rust-resistant so you can also store it outside or just bury it in a ground.  

Coinplate features no visible branding or markings that could easily tell a potential robber what he has found so it can be overlooked by a thief. On the outside it looks just like a steel slab. The logo on the front plate is just a sticker that you can easily remove.

Included you will find also tamper evident security labels. This way you can be sure no one has seen your seed while you weren’t watching.
