Yes, you can create your custom hardware wallet easily, just contact us via the form below.

No, you don’t need to download any apps to use KEYRING HARD WALLET.

The wallet is based on the Web NFC technology, allowing users to get immediate access by tapping the card on the back of a mobile device.

Unfortunately, due to Apple’s policy, the app would not work on iPhone.

We highly recommend users to use KEYRING HARD WALLET on Android devices.

Your Private Key is encrypted on your physical NFC cards.

Only you will have access to your Private Key as the key is not recorded anywhere and would not appear on the wallet interface. 

This removes the issue of key management, and allows your Private Key to literally stay within your pocket at all times.

(*) Your card is your key.

Yes, you can extract your Private Key encrypted on your NFC cards by using KEYRING PRO app.

We will provide a detailed instruction on this page in the next release of KEYRING PRO mobile app.

When you first purchase a KEYRING HARD WALLET package, the cards will be blank, not to say they’re empty and ready to be activated.

Once you activate them, a random wallet will be generated with its Private Key encrypted and stored locally on your two cards only.

You will then add in your custom passcode to protect your two cards. 

The process is only complete when you see a wallet interface with 0 in balance.

For security purposes, we do not support users to import old wallets to KEYRING HARD WALLET.

As a reason, your old wallet might have approved untrusted Dapps, or imported to untrusted wallets in the past, which may cause a severe security breach in the future.

Each NFC Card will have a unique ID recorded in our database. We can base on this information to reset your passscode on our interface. 

In fact, that’s all we can do. Your Private Key is generated randomly and stored locally on your cards in an encrypted format, meaning no one can reach it, including our team.

A hardware wallet is a physical device that stores your cryptocurrency private keys in a secure offline environment. This makes it much more difficult for hackers to access your funds, as they would need to physically steal your device in order to do so.

There are many benefits to using a hardware wallet, including:

  • Increased security: Hardware wallets offer much higher security than other types of cryptocurrency wallets, such as software wallets or online wallets.
  • Offline storage: Your private keys are stored offline on the hardware wallet, which means they are not accessible to any internet-connected devices. This makes it much more difficult for hackers to steal your funds.
  • Support for multiple cryptocurrencies: KEYRING HARD WALLET supports 04 different chains, so you can store all of your coins in one place.
  • Easy to use: Just tap the card on the back of your mobile device to use.

KEYRING HARD WALLET supports all ERC-20 tokens and NFTs on 06 different chains with the same address, including Ethereum, Polygon, Binance Smart Chain, Avalanche, Arbitrum and Optimism.

1. On mobile browser, go to keyring.app/keyring-hard-wallet/

2. Click ‘Activate’

3. Scan a card, tap ‘Next’

4. Scan it one more time, set a passcode

5. Confirm the passcode

6. Add your email, tap ‘Submit’

7. Scan the card again

8. Scan the second card

There are a few things you can do to keep your backup card safe:

  • Store your card in a safe place where it cannot be easily stolen;
  • Keep your PIN code memorizable;
  • Don’t extract the encrypted Private Key or insert it on random wallets;
  • Keep your card in a dry and cool place to avoid damage.

If you only lose your main card, you can use your backup card to replace it. However, we highly recommend you to extract your Private Key and keep it in a secure location in this case, since you have no backup left.

If you lose both of the cards, it’s most likely you will lose access to your funds permanently. As a reason, your Private Key is only stored locally on your two cards, where no one can reach it, including our team.

It’s best to keep your cards separately in dry, cool, and secure places, especially with your backup card.

Yes, you can reset your card, just go to hardwallet.keyring.app/clear-tag
