MATERIAL BITCOIN

What is a bitcoin wallet?

A Bitcoin wallet is software for storing, sending, and receiving bitcoins. Like a physical wallet holds cash, it holds cryptocurrency. Each wallet has a unique address, which functions like an account number on the Bitcoin network. You can share this address to receive bitcoins or use it to send them to others.

Is Material Bitcoin safe?

Yes. Material Bitcoin is a cold wallet designed to securely store your bitcoin offline. Since it is not connected to the Internet, your private key remains protected from hacking. Made from AISI 304L stainless steel, it offers both durability and security for long-term cryptocurrency storage.

How do I know that the private key generation process is secure?

The private key engraved on each Material Bitcoin wallet is like a bank card’s PIN, making it highly sensitive data known only to the wallet owner. To ensure security, the manufacturing process uses an open-source key generator and engraves the wallet without human intervention.

Can I make transactions with my wallet?

Yes, you can! Your wallet is used to store your funds. If you want to make a transaction, you just need to use your address or QR code that appears on the front to send or receive bitcoin.

How can I convert my dollars or other currencies to bitcoin and add them on my Material Bitcoin wallet?

First, create an account on a Bitcoin exchange platform, then transfer your funds to the address on your Material Bitcoin wallet. You can do this by scanning the QR code or manually entering the wallet address.

How do I move some or all of the bitcoins from my wallet to another address?

The Material Bitcoin wallet is designed so that you don’t need to send your bitcoin to another address, as the engraved address is nearly hacker-proof—unless you reveal your private key.

However, if you still want to move your bitcoin, you’ll need to import your private key into a trusted wallet manager like Exodus on your mobile device. Here’s how:

1. Download the Exodus app from the Play Store or App Store.
2. Exodus will automatically create a new wallet for sending and receiving funds.
3. In the Bitcoin section, click the settings wheel and select “Add bitcoin from a private key” to import bitcoins from another address.
4. After importing, you can send bitcoins to any address by using the “send funds” feature for each cryptocurrency.

You can watch the full video tutorial to follow the steps in detail.

What would happen to your wallet if we no longer exist as a company?

If Material Bitcoin no longer exists as a company, your wallet would remain fully functional. Since it’s a cold wallet with your private key engraved on it, you would retain complete control over your bitcoin. As long as you keep your wallet safe and your private key secure, you can continue managing your funds using any compatible Bitcoin wallet manager without needing the company for support or updates.

You can also enter the address of your Material Bitcoin card (never the private key!) in a search engine (like blockchair.com) to check your balance.

If it’s more comfortable for you, use a mobile app like Wealth Check Bitcoin (Android) or Satpile (iOS). With it, you can directly scan your Material Bitcoin card’s QR and see your balance in bitcoin and its current equivalent in euros.

We accept payments with debit/credit cards, PayPal and cryptocurrencies such as Bitcoin, Ether, USDT…

What happens if I sell all my bitcoin?

If you sell all your Bitcoin, you will no longer have any Bitcoin in your Material Bitcoin wallet. However, the wallet itself and its private key remain secure and usable for future transactions or storage of other cryptocurrencies. The balance on the Bitcoin blockchain associated with your wallet address will reflect the sale, but the wallet will still exist as a tool for managing cryptocurrency.

How do I convert the bitcoins in my Material Bitcoin wallet into dollars or other currencies?

To use Bitcoin from your Material Bitcoin wallet, import the private key into a Bitcoin wallet manager like Exodus. Be cautious, as entering your private key into any device exposes your funds to the security of that device. Once your bitcoins are in Exodus, you can transfer them to other accounts or exchanges, and convert them to dollars or other currencies. Watch the video tutorial for detailed instructions.

How long does it take for the wallet to arrive?

We send your Material Bitcoin wallet securely via registered mail to the address you provide. It usually takes between 2 and 10 days to arrive, depending on your location.

FAQs

MATERIAL SHADOW

What is Material Shadow?

Material Shadow is a more secure version of the Material Bitcoin cold wallet. Key features include:

* The full wallet address is only accessible via a QR code in the center.

* There is no visible reference to Bitcoin, keeping it discreet if found by someone unfamiliar with Material Bitcoin.

* The wallet is split into two parts, ensuring that both halves are needed to access the wallet, scan the QR code, or identify the address. This split design enhances security against theft.

What is the difference with the Material Bitcoin wallet?

The Material Bitcoin wallet is a single plate with the address in the center and a QR code on one side. In contrast, the Material Shadow is split into two pieces, where the QR code is only complete when both halves are combined. To check the balance or make payments, you don’t need both halves because the package also includes the Material Bitcoin Portable edition—a thinner plate engraved with the public address and QR code. You can carry it with you safely, as losing it won’t risk your funds.

What does separate shipping mean?

Additionally, you have the option to choose how the two halves of the Material Shadow wallet are delivered. We can send them together in the same package, or, for enhanced security, we can ship the two halves separately. In the latter case, the halves will arrive in different envelopes, through two different packages, and even via two different delivery companies to minimize any risk of theft.

This demonstrates our strong commitment to the security of your wallet.

What happens if I lose the Material Bitcoin Portable?

Absolutely nothing happens. Since only the public address is engraved, the only thing you can do with the Material Bitcoin Portable is to receive payments and check your balance.

The private key is only engraved on the back of your Material Shadow wallet and, as it is split in two, you need both halves to see the full private key.

What is the purpose of Material Shadow?

Material Shadow is designed for those seeking maximum security for their funds. The wallet is split into two parts, allowing you to store each half in separate locations for added protection. Meanwhile, you can still carry your Material Bitcoin Portable to easily check your balance and receive payments quickly, without compromising security.

What is the Material Bitcoin Portable edition?

The Material Bitcoin Portable is a small card that you can carry in your wallet, without compromising your funds as it only has the address and the QR of the address engraved on the front of the card.

We say you do not compromise your funds as the private key is only engraved on the back of your Material Shadow badge.

How do I check the balance of my Material Shadow?

Using the QR of the address on your badge (or the QR in the Material Bitcoin Portable) in the following ways:

You can scan the QR of the address on your Material Shadow wallet (never the private key!) in a search engine (like blockchair.com) by hitting the camera button, to check your balance.

If you find it more convenient, use a mobile app like Wealth Check Bitcoin (Android) or Satpile (iOS). With it you can scan the QR of your Material Shadow badge and not only see your balance in bitcoin, but also its current equivalent in euros.

Important: Never enter the private key of your Material Shadow badge on a website. If you do so, you will irreversibly lose control of your funds.

Can my bitcoin be taken from me if half of my Material Shadow gets stolen?

To access your funds, both halves of the Material Shadow wallet are required. Since the private key is split between the two parts, it remains incomplete unless the halves are combined. With only one half, neither you nor a potential thief can access the funds, as it’s impossible to reconstruct the private key from just one part. This provides an extra layer of security for your assets.

This means that for every USDT issued, Tether Limited claims there is an equivalent US dollar reserve to back it. USDT is commonly used as a way to maintain price stability in the cryptocurrency market, as its value is pegged to the US dollar.

Moreover, it is made of AISI 304L stainless steel which makes it a highly durable and secure device.

How does the Material USDT wallet works?

The Mnemonic Seed

Your Material USDT wallet includes a unique mnemonic seed, which is crucial to protecting your funds. The seed, safeguarded by a sticker, is the key to controlling the Ethereum stored on the wallet. Never share or expose it—knowing this seed gives someone full access to your tether.

This seed is the only thing you need to transfer your tether to another address, and you are the only person in the world who knows it.

That’s why it’s essential to:

Never let anyone memorize, copy, or photograph your mnemonic seed.
Protect your wallet from loss or theft.
Never input your mnemonic seed on any website.

If you do any of these, you could permanently lose control of your funds.

The Address

The address is public and used to send tether to your wallet. It can also be used to check your balance or transaction history. Unlike the mnemonic seed, the address is safe to share or enter on any website.

Where Are Your Tether?

Your wallet itself isn’t electronic or connected to the internet, so your tether isn’t physically stored on it. Instead, your tether is securely recorded on the Ethereum blockchain. It is yours because thousands of computers worldwide are in sync, confirming that the tether belongs to the address on your wallet.

This decentralized record ensures your tether is absolutely yours—much more securely than any money held in a bank. The tether’s ownership is immutable, recorded across the blockchain, and verified globally, so you can rest assured that your funds are safe.

How do I send some or all of the tethers from my wallet to another address?

You must import your seed phrase into a tether wallet manager (such as My Ether Wallet or Metamask, for example), and from there you can send it to your trusted exchange to sell it without further complications.
