Why do you need a metal crypto wallet?

Hardware and software wallets both require you to write down a backup password (a seed phrase), which you will use to restore the wallet and your accounts if it’s broken or damaged. Every user of hardware or software wallet is strongly encouraged to make a backup of their seed words and keep it safe. This is good advice as you will need this wallet backup if you put your pin wrong a few times and the wallet erases itself, or it simply breaks down one day.

Most users just write down their hardware wallet backup – a seed phrase – on a piece of paper and are done. But you have to understand, that this backup is essential to owning your coins.

If the paper backup is destroyed or lost, you can lose access to your funds forever, and paper can be damaged or misplaced easily. This is why it is so important to have this backup made on something more durable.

There are ready-made metal cryptocurrency wallets available that are made from ultra-thick stainless steel plates and are super easy to use. 

With best metal crypto wallets like Coinplate Alpha, you can make an ultra-durable backup in just a few minutes on your kitchen table.

Steel crypto wallets are essential to keeping your hardware or software wallet backup safe. We have to say it again, you have to keep your wallet backup phrase safe, or you can lose all your funds. Crypto steel backups and especially stainless steel crypto wallets are the best way to protect your wallet recovery phrase against any possible accidents and disasters.

Metal crypto wallet – how it protects your backup

From our own experience, we can say that you have to protect your wallet recovery phrase against the most common accidents and disasters. You never know what the future will bring, but you can avoid almost all risks by simply using a proper recovery phrase backup for your hardware wallet and sleeping well for years. You can focus on watching your portfolio grow and not worrying about where you put this weird paper slip in a few years.

Seed phrase misplacing risk – can cost you millions but it’s easily preventable

For most people, the biggest risk is simply misplacing the backup – there are countless stories of people throwing away a piece of paper with their wallet’s backup as it was stored with other documents. 

Cleaning your office desk, clearing your attic or garage – it will be much easier to notice a heavy metal object like a metal crypto wallet, than a piece of paper stuck in other documents.Especially as most people will hide their precious backup in the big pile of other papers just so it will not be found to be a burglar. In reality, they usually forget where it was hidden after some time, not to mention their parents or spouses. Quite often this backup will be simply thrown away by your family member as it doesn’t look like something important at all.

The best metal cryptocurrency wallets like Coinplate, can be secured to a wall, attic beam or your house foundation thanks to special mounting holes. In the box you will even find some wood screws for that, so you can do it right away. Not to mention that the best recovery phrase backup will be a heavy piece of solid metal, which will not be so easy to overlook when going through a box of documents meant for thrash, even if you keep it there.

Fire and heat damage – ink and paper stand no chance, better use fireproof metal wallet

Your standard paper seed phrase backup will stand no chance against house fires. Your backup could be destroyed, even if not burned directly because heat makes ink fade. To keep things even worse, when the fire brigade arrives, they will spray gigantic amounts of water all over your house, apartment or block of flats.

Even if the fire was in your neighbour’s flat, they will probably totally soak your place just to contain the fire. The water will definitely destroy your paper backup along with all paper photos and other documents.

Furthermore, ink on paper could fade while being exposed to heat much earlier than you expect. Standard pen or printer ink should resist fading for at least 5 years, but if you keep your paper backup next to a radiator, computer or sunny windows, it could make your paper backup worthless much sooner.

This is much different with a proper crypto steel wallets. Stainless steel crypto metal wallets can withstand temperatures of up to 1.400°C/2.500°F, while house fires reach up to 850°C/1.500°F, but usually are less than that. Thanks to their strong build, the best metal wallets will survive also rapid cool down from generous soaking by firemen, without risk of cracks. Water will also not be a problem at all. Because you will literally mark your phrase in stainless steel, it will be not vulnerable to any heat sources, unless you throw it inside a smelting furnace.

Water and moisture damage – your recovery phrase backup has to survive that

When it comes to paper, nothing will destroy your paper wallet backups faster than water and moisture. This is a reason, why libraries and archives spend millions on keeping their storage facilities dry.

Direct contact with water will probably be enough to make your paper copy of the recovery phrase unreadable and in the best scenario, it will just make it difficult to read. If you are able to spread the paper and dry it out, you might save the paper itself but the ink will be probably gone or smudged. 

Water damage can be caused by different things like soaking with sprinkles activated by the fire alarm in your office or even your upstairs neighbour’s faulty pipes. Even in your own house, the dishwasher or washing machine can flood your place and you might not be able to notice before it soaks the room below.

Furthermore, paper documents happen to be destroyed quite often by moisture and mold. Keeping your paper backup in an attic, garage, tools shed or self-storage room can make it vulnerable to moisture and mold damage.

With metal, it is no issue, especially if you use stainless steel crypto wallet that could be literally kept in water for years, without a problem. Good grades of stainless steel are corrosion resistant and can even withstand long-term exposure to salt water, so you will have literally nothing to worry about. Furthermore, a well-made metal crypto backup will also survive freezing and thawing without a problem, which could be devastating for your paper backup.

Burglary or theft risk

Most people keep their paper backups inside their books, in the safe, with other important documents, just because these are the places where your paper backup will be not exposed to fire or water Some people even keep their seed phrase backup together with the hardware wallet, which should be avoided. More creative and better hiding spots are usually more susceptible to moisture or weather in general. This means that burglars can find it while searching around your apartment and turn everything upside down.

With a durable metal crypto wallet, however, you can hide it anywhere, knowing that no weather, water or anything else could destroy it. Want to hide it in your dog’s house? How about putting it inside drywall? Maybe you will like to bury it in the ground, grandpa style?

With a good quality stainless steel crypto wallet like Coinplate, you can do that and sleep well at night. You can get creative and come up with some really good hiding spots that will not be found by burglars or nosy family members. Furthermore, the best metal crypto backups have removable branding and don’t look interesting to anyone, even if found. For example, Coinplate metal wallets have a very simple look and resemble a slab of steel or a piece of scrap metal.

We already mentioned it earlier but solid seed phrase storage solutions should have a way to securely mount it with screws if needed, so you can fix it to the attic beam, inside of your dog’s house or even somewhere in your kids’ tree house. This gives you a lot of flexibility when it comes to finding a perfect hiding spot.

House collapse and other disasters

This is something that anyone doesn’t want to experience in their lifetime. But your house or apartment building could be damaged or destroyed by natural or man-made disasters. Houses all around the world are destroyed by fire, mining or fracking operations, and disasters like earthquakes, hurricanes or tornadoes. If that happens to you, your paper backup with all your portfolio will be gone. Remember that even if it’s worth now $20k, it could be worth 10x in a few years and you will much regret not taking care of your backup.

Getting a good metal crypto wallet will let you fix it with screws to your house foundations or basement, you could also bury it in the ground, where it should survive even major disasters like tornadoes and house fires. The ultra-durable metal backups like Coinplate should also survive the house collapsing as they are made from ultra-thick stainless steel plates and are exceptionally strong. 

Time deterioration and ink fading

When it comes to ink from your printer, even if it’s a laser one, time will make your documents fade away. The same with ink from your pen. Depending on the quality of the ink, the writing could start to fade even after just five years and make the document unreadable. This will happen even faster when exposed to heat, humidity or sun. This is why paper backups of your software or hardware wallets are not a great idea, especially when most cryptocurrency owners tend to hold their coins for a long time.

Furthermore, there are critters around that just happen to like eating paper. Various rodents and insects love eating your books and other documents. The worst part is that they usually eat the inner parts of your paper stack or book, so you might not be able to notice it for a long time.

Some people try to increase the durability of their paper backup by wrapping it in a ziplock or laminating it. 

However, this doesn’t change the fact that ink can fade and paper in plastic can get moldy with no air circulation.Metal crypto wallets made from Stainless steel plates, where you physically mark your seed phrase with indentation will last for decades and no rodent or insect can eat that, even if they want to. Time will also not be an issue when the material itself is rust-resistant. You could probably pass your Coinplate backup to your grandchildren and it will still be like new.

What is the best metal crypto wallet?

We discussed some risks that your paper backup is susceptible to. Good crypto metal wallets should be able to withstand all of that without being vulnerable to other possible risks.

To sum up, the best metal crypto wallet should be:

  • Fireproof to withstand house fires
  • Waterproof to survive rain, soaking by firemen and high air-humidity
  • Rust-resistant & corrosion resistant to survive decades even in a humid environment
  • Easy to overlook (simple looks and no logos) to not draw attention
  • Easy to hide (mounting holes, compact built) so you can find a great hiding spot
  • Ultra durable (solid build) to survive disasters like house collapsing
  • Offline and hackerproof to completely avoid being exposed to hackers
  • Easy to use and read, so you will not make a mistake while making your precious backup or reading it in a few years.

Extra tips from our team on keeping your wallet recovery phrase safe:

  • The order of words in your seed phrase is important. Don’t ever change the order of the words in the seed phrase, it will make your seed phrase unusable.
  • Don’t take photos of your backup and avoid even reading it aloud to avoid intercepting it by malware or hackers.
  • Don’t input your seed phrase (or even parts of it) into a computer or other electronic devices apart from hardware wallets.
  • You should only use seed phrases generated randomly, preferably by the wallet.
  • Always double or triple-check if you marked your seed correctly. You may use a recovery check feature of your wallet to do that.
  • Use tamper-evident stickers to protect your seed backup or hardware wallet and be sure no one used them when you weren’t watching.
  • You should avoid encrypting or making your seed phrase hard to read if you are not sure you will be able to decipher it back in 5-10 years. It will be better to just use a passphrase (25th word) and make a solid backup of it separately from the seed.
  • Use extra passphrase or seed phrase splitting if you are worried that someone might access your seed phrase or force you to show it. Please be aware that these are some advanced techniques that require prior research.
