How does my MATERIAL USDT work?

Mnemonic seed

Your wallet has a mnemonic seed, unique and protected by a metallic sticker. It is literally the key to access your funds. Keep it safe and do not share it!

The mnemonic seed is all you need to transfer your USDT from the Ethereum network to another address. You are literally the only person in the world who knows the mnemonic seed that is engraved on your Material USDT wallet.

Mind the following recommendations:

  • Do not ever allow anyone to memorise, copy or photograph your mnemonic seed.
  • Do not lose your wallet.
  • Do not let anybody take the wallet from you.
  • Do never use your seed on a website.

Any of the previous case will make you lose control of your funds

The address

The public address gives (who possesses) the only information required to send money. Besides, it gives permission to check funds or the transaction history. This address could be shared to anyone or added on websites since it does not compromise your funds.

Where is your USDT stored?

Your wallet has no electricity and it works exclusively offline which means that your USDTs are not physically in your wallet. The USDT is written in thousands of computers and your secret key is the only way to give access to them. That’s how the Ethereum blockchain works.

Your USDTs are absolutely yours and there is no other better way to own them. The concept is exactly the same as the money saved in bank accounts. It is there but not physically.

Thousands of synchronised computers guarantee that your USDTs are in your wallet. This is the highest level of security known and that makes our wallet extremely safe.

Does my MATERIAL USDT wallet come with funds?

It is sent ready to use and it does not have funds yet. Mind that the Material USDT plate is a cold wallet for USDT on the Ethereum network.

Purchasing USDTs could be done from any exchange and be sent to your wallet via the Ethereum Mainnet.

You can do this from your exchange account in the send funds section, by entering the address as the sending address or by scanning the QR.



Follow the steps to fund an account:


  1. You must go to your personal dashboard on the exchange where you hold your USDT and select the “Withdraw” button.
  2. Click on USDT as the cryptocurrency chosen to withdraw. Select the amount. After that select Ethereum network and then send it to your Material USDT wallet.
  3. Finally, proceed to scan the QR or type down the public address shown on the front of the wallet. This second option has room for error and consequently could make you lose your USDT in that specific transaction.
  4. Go on to check your balance to confirm the success of all your transactions.
