What happens if I can't authenticate to my hardware wallet?

Authentication using Fingerprint or PIN is required to unlock your hardware wallet. If a user fails to authenticate over multiple attempts on the Biometric Wallet, the device will automatically wipe itself and delete all information stored inside. You can recover your wallet using the 24 words mnemonic.

In the case of the Card wallet, failing 10 consecutive authentication attempts will permanently block the card.

Will I lose my crypto assets if I lose my D'CENT Wallet?

We provide a recovery function in case the wallet fails or the wallet is lost. You can restore the entire wallet using the 24 recovery words given when creating the wallet. For more details on wallet recovery, please click .

Are crypto assets stored in the hardware wallet?

The crypto asset itself is not stored in the hardware wallet. Private keys are stored in the hardware wallet, and only other information related to the account is managed. Crypto assets exist on the blockchain network, and the software application reads the information and displays the calculated balance.

How does the asset get recovered when I recover my wallet?

It uses 24 recovery words to recreate the private key that the hardware device has stored in the past. The original crypto asset does not exist in the hardware wallet, but exists on the blockchain. The recovered key is used to retrieve the information of the existing cryptocurrency asset and display it in the mobile app. Click to learn how to recover your wallet for fingerprint authentication type cold wallet.

Does the manufacturer of D'CENT(IoTrust) know my private key?

The wallet's private key is generated by the security chip inside the hardware when the customer receives the hardware device and creates the wallet. The private key generated inside security chip is never exposed to the outside. For this reason, the customer's private key is also unknown to the manufacturer.

Does the manufacturer(IoTrust) operate a server? Does IoTrust have my personal information and my private key?

IoTrust does not operate a server that manages customer's private key and personal information. However, IoTrust does operate general management servers, such as firmware management servers and homepage servers, which are specifically for managing hardware firmware.

Which cryptocurrency assets are supported on D'CENT Biometric Wallet?

How do I connect D'CENT Biometric Wallet to the mobile app?

D'CENT Biometric Wallet and mobile app connects primarily using Bluetooth. If you are using Android, please refer . If you are using iPhone, please refer . On Android phones, you can also connect via a USB cable. Click for how to connect USB cable with an Android phone.

I have multiple phones. Can I download the D'CENT Mobile App on my other phone to use my Biometric wallet?

You can use the Biometric wallet with more than one phone. However, you can only use the Biometric wallet with a phone that is currently connected via Bluetooth. If you intend to use the Biometric wallet with multiple phones, make sure you disable or disconnect the Bluetooth connection on the first phone then establish Bluetooth connection on the secondary phone that you will use.

I lost my phone / I am changing my phone. Can I use the Biometric Wallet on the new phone if I download the D'CENT Mobile App?

You can certainly use it on a new phone. The D'CENT Mobile App (Biometric wallet mode) only holds publicly available information such as the cryptocurrency accounts(public addresses) that you have added for management. D'CENT Mobile App only provides user interface so that you can get a view of accounts information. Notice that every time that you run D'CENT Mobile App, it synchronizes with the Biometric Wallet. During the synchronization, the Biometric wallet provides the correct account information (public address) to the D'CENT Mobile App, making sure that what you see on the Mobile App is the correct account address.

In the case of Bitcoin, it is recommended to change the address once it is used to protect a certain level of privacy because anyone can see the transaction details and balance when the address is exposed. This is proposed in the BIP-32 and BIP-44 specifications related to Bitcoin, and many hardware wallet companies support this function.

In the case of D'CENT, we provide a function that shows the list of used addresses from the mobile app to mitigate the discomfort of not knowing the previously used Bitcoin addresses. To find out how to check all your BTC public addresses, please click .

Since the D'CENT mobile app maintains a transaction record for all addresses, there is no problem to continue using the bitcoin address before the change. For more information about the Bitcoin address, please click .

Why does it take long to transfer a large amount of Bitcoin?

When transferring Bitcoin, fragments(small amounts) of bitcoins from many blocks are collected and transmitted. If your Bitcoin balance is fragmented in too many blocks, it will take a lot of time to collect and to send them all. This isn't always the case, but the larger the number of Bitcoins you send, the more likely it will be to collected from multiple blocks, which will usually take more time. If a transaction takes too much time, it can have multiple side effects. Customers may think that the Wallet function has stopped working and it actually increases the chances of an error. For this reason, D'CENT provides a method for dividing and transmitting multiple transactions if the bitcoin account balance is highly fragmentation. For example, a large sum of single bitcoin transfer request may be divided into 2 transactions, thus the customer will confirm twice.

Can I cancel a pending transaction?

Due to the nature of blockchain cryptocurrency protocol, a transaction cannot be canceled or changed once the transaction is broadcasted to the blockchain network. The only option you have is to wait for the pending transaction to complete. If a pending transaction is not validated by the blockchain network for an extended period of time, the pending transaction will get dropped. However, for an Ethereum transaction, a pending transaction can be canceled by sending a new transaction with a small amount of Ethereum and a higher transaction fee to your own Ethereum address. If the newly sent transaction gets validated first before the previous pending transaction, the pending transaction will be canceled.

Ripple (XRP) remittance is not working. What are the precautions when sending to an Exchange?

• After the transfer, the remaining balance in your account must be at least 10 XRP.

• Balance before remittance-(remittance amount + commission)> = 10 XRP.

• Many exchanges require a Destination Tag when depositing XRP as an exchange. When sending money to an exchange, please make sure that the Destination Tag is required before sending money. If you do not fill in the Tag, your money may get lost forever or it may take a very long time for the Exchange to recover your fund.

Why is the remaining 10 XRP in my wallet not transferrable?

requires a transfer of Ripple of 10 XRP or higher to convert a newly created XRP wallet address to an activated state. The cost of address activation is 10 XRP and it will be locked up to the XRP account, this means that the reserve amount of 10 XRP cannot be withdrawn.

Coin was sent to my wallet, but the balance is not showing. What should I do?

In most cases, it is the case that you entered the address incorrectly or it takes a long time due to low transaction fee paid.

• If you received a coin, please check it on the mobile app.

• Try refreshing the account balances while remaining on the "Account" tab. Pull down the screen and release to refresh.

• Try searching the address from Block Explorer and check if the SEND / RECEIVE was successful.

I created many accounts but, now only few of them are actually used. Can't I only see the accounts that I want to see?

• D'CENT Biometric Wallet shows all supported coins.

• The mobile app uses a method of adding an account, so please only add the account you actually use. If you added a lot of accounts for testing, you can delete all the account information by following the instruction as below.

  • To delete all accounts information on Biometric Wallet, go to [Setting] -> [Security] -> [Delete Account].

Isn't it vulnerable to security when connected via Bluetooth?

With exception to the publicly disclosed transaction data from the blockchain, ALL important data is processed inside the security chip in the Biometric Wallet. Therefore, even if the data transmission in the Bluetooth communication is tracked, the assets inside the cold wallet cannot be hacked.

Can I use my mobile phone and D'CENT Biometric Wallet using the wired connection?

For Android phones, you can use it by connecting with an OTG cable. Please click for more information.

Can I send coins using only the Biometric Wallet without the mobile app or a PC software?

Since the D'CENT Biometric Wallet does not have internet network function, it is necessary to communicate with external software to transfer coins. We recommend using the D'CENT mobile app.

ERC20 token is a token used on Ethereum. On Ethereum, tokens can be issued in the form of smart contracts. Tokens that conform to the ERC20 standard among smart contracts are called ERC20 tokens. Currently, almost all tokens running on Ethereum follow the ERC20 standard. For a list of ERC20 tokens supported by D'CENT Wallet, refer to the following link. https://www.dcentwallet.com/en/supportedcoin

The ERC721 token is also called NFT (Non-fungible Token) and NFT is a non-replaceable token. While each ERC20 token has the same value, the ERC721 token has a unique value for each token. In other words, it is impossible for the NFT to replace one token with another. ERC20 is issued for functions similar to currency or points. On the other hand, ERC721 is used in cases where each token has a unique value, such as a game item.

Ripple (XRP) account activation

If you have added your Ripple (XRP) wallet address for the first time, it is disabled. Ripple's policy requires a purchase or transfer of Ripple of 1 XRP or higher to convert the Ripple wallet address to an activated state. Therefore, the corresponding 1 XRP will permanently lock-up at the corresponding wallet address. If a permanent lockup is made at the address of the Ripple wallet, it is assumed that only 99 XRP can be transferred, excluding the 1 XRP, which is the permanent lockup amount.

XRP Destination Tag

Users' ripple wallets assigned by the Exchanges use the same address. In other words, User # 1, User # 2, User # 3, all use the same ripple address. To distinguish a user's account from another user, the Exchange will assign a Destination Tag to the user's account, which is an uniquely identifiable number. Therefore, when sending XRP to a recipient wallet address created from the Exchange, you MUST enter the Destination Tag so that the Exchange will complete the deposit to the recipient's wallet account.

SegWit stands for Segregated Witness and, is a method of separately storing the signature part of the transaction record in order to reduce the data size stored in the block.

At the time SegWit was proposed, there were too many bitcoin transaction, it caused higher transaction fee. It was very important to solve bitcoin's block size limitation. This proposal has been adopted,

Before adopting SegWit, the saturation of the bitcoin block size caused the transaction fee to continue to rise. A resolution to reduce the block size received greater attention than the security enhancement effect to prevent transaction volatility.

In Bitcoin blocks, signatures take up surprisingly large amount of data space. If you save the signature separately in the block, more transactions data can be included in the data space that was once previously occupied by the signature data. In SegWit block, digital signature is collected separately to save 1MB of data space in a block, this will allow adding more transactions into that data space.

With the introduction of SegWit, major networks have shortened the processing time of tasks and lowered the transaction fees.

Both the Ledger wallet and the D'CENT wallet follow the same BIP standards for wallet recovery. However, each wallet service may have used a different wallet derivation path to generate a private key for each type of digital asset that each wallet service currently supports.

Below is a screenshot that compares the account addresses (ie: BSC & ETH) between the Ledger wallet and D'CENT wallet. In this example, D'CENT wallet was recovered using the mnemonic code from the Ledger wallet. Notice how the addresses for the BSC and ETH accounts are the same because the wallet derivation paths are the same between these 2 wallet services.
