Step-3 : Write down the recovery seeds

Before you begin - What are recovery seeds(Mnemonic code)?

Recovery seeds are the codes that you use to recover your wallet.

If your D'CENT Cold Wallet is ever lost, stolen, damage, or wiped and you no longer have any access to your wallet, using recovery seeds is the only method of recovering your existing wallet.

You MUST write down all the recovery seeds on the Recovery Card and keep it secured in a safe place.

Step-4 : Completing the Initial Setup

Congratulation, you have passed the quiz and your new wallet is created. From your cold wallet, you can check the lists of coin accounts available. You are now ready to use your new wallet together with the mobile application.

Check for the latest Firmware

Once you have completed the Initial Setup, make sure to visit D'CENT Wallet homepage and check for the latest firmware available. Newer version of firmware may include additional support for cryptocurrency assets and new wallet features.

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?

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?

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?

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.

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?

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.

  • You can search for "bitcoin explorer", "ethereum explorer", or "XRP explorer" in the search engine.

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].

  • Re-add only the accounts you want to see from the mobile app.

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?

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.

How secure is D'CENT Wallet? What features are included to enhance security?

D'CENT Wallet is a product made by top experts who have long worked in cryptographic chip and Secure OS development. Credit card, banking card, USIM card, TEE, etc. have been developed for nearly 20 years and D'CENT Wallet is developed using security techniques learnt in the field. The following is a brief introduction to security considerations.

• Using smart card security chip (credit card and bank sector certified for security) for secure key storage and secure processing of transaction signing

• Fingerprint algorithm is mounted on the smart card to process fingerprint information only within the security chip

• Proprietary Secure OS

Can I perform firmware update from my mobile phone?

In general, the firmware update is performed by connecting the device to a personal computer. For those in possession of the OTG cable, the firmware update can be performed directly from the mobile phone (Android only). OTG cable connection is not supported by Apple devices.

Firmware update stopped in the middle. What should I do?

Will I be able to continue managing my assets if D'CENT (IoTrust) goes out of business?

Although highly unlike for D'CENT (IoTrust) to stop the wallet service, but if that situation ever happens, you will be able to continue managing your assets in the following ways.

• Customers manage assets by transferring funds to another wallets other than D'CENT.

• D'CENT will release the mobile app or software to the public for anyone to use or modify if the service is stopped.

• We are continually promoting integration with other popular software wallets. Customers will be offered a variety of options to choose from among several alternatives.

Is there a way for my family to access my wallet if I die or no longer able to manage my wallet for any other reasons?

The main information that allows managing your wallet are password, fingerprint, and recovery card. In case of emergency, you can manage it in the following way.

• Share recovery words

  • If you have shared the recovery word with your family, your family can use them to recover the assets.

• Enroll second fingerprint

  • You can enroll up to 2 fingerprints on the Biometric Wallet. If the second fingerprint is registered in the hardware, it can be used to unlock and access the funds inside.

Is there another wallet other than the D'CENT mobile app that I can use together with the Biometric Wallet?

Currently, there are no other wallets available other than the D'CENT mobile app. Since we are working with several software wallets, using D'CENT hardware with other wallets are not far away.

We will announce it separately when the work is completed.

There are several wallet modes, such as Biometric Wallet, Card type Wallet, and Software Wallet. Are they all using the same private key?

Since each wallet is a separate wallet, they all use different keys. Assuming that you are using the mobile app in all 3 different modes, then you are using 3 different wallets with different private keys.

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.

List of recovery-compatible assets (mainnets)

The wallet derivation paths for the following cryptocurrencies are the same between the Ledger wallet and the D'CENT wallet. This means that using the Ledger's mnemonic code, the same accounts(private keys) can be generated on the D'CENT wallet.

• Binance Smart Chain (BSC - BNB)

• Bitcoin Cash (BCH)

• Cosmos (ATOM)

• DASH (DASH)

• Dogecoin (DOGE)

• Ethereum (ETH)

• Ethereum Classic (ETC) - select 'Ethereum Classic - Legacy' when adding to D'CENT wallet.

• Horizen (ZEN)

• Polygon (MATIC)

• Solana (SOL)

• Stellar (XLM)

• XRP (XRP)

• Zcash (ZEC)

• TRON (TRX)

How to recover token assets (ie: ERC20, BEP20, TRC10, ...Etc.)

It is likely that you also held token assets in the Ledger wallet. Token assets are digital assets issued by blockchain projects (service providers) via smart contracts that exist on EVM-compatible networks such as Ethereum, Binance Smart Chain, Tron, Polygon, and more.

Each EVM-compatible network has a name for its token standard which is represented or marked as 'ERC20' for tokens on the Ethereum network, 'BEP20' for tokens on the Binance Smart Chain network, 'TRC10' and 'TRC20' for tokens on the Tron network, 'Polygon-ERC20' for tokens on the Polygon network, and so on. The token standards help identify easily which network(s) the token assets were issued on.

For example, let's say you held ETH coins and USDT tokens (ERC20) in the Ledger wallet. To recover these assets, you must add two accounts to the D'CENT wallet. First, add the Ethereum account to recover ETH coins. Next, add the USDT (ERC20) account linking it to your Ethereum account and your USDT tokens will be found.

You can easily search for which digital assets are supported (listed) in the D'CENT wallet by visiting the link below.

If the token asset that you are looking for is not displayed in the list, you can also manually add the account as a custom token account. For detailed instructions, please refer to the guide below.

Enter the receiver address and the Destination Tag

1) From mobile app, press the “Send” button of the Ripple (XRP) account to be used for the transaction.

2) Enter the wallet address of the other party (receiver) and enter the Destination Tag if you are sending XRP to an address that is created by an Exchange.

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.

Example of XRP account created from an Exchange

Picture above is an example of XRP wallet account created from an Exchange such as Binance. When you press "Deposit" for XRP, it will show the XRP deposit Tag (9-digit unique number). On the bottom, the XRP address is shown.

XRP wallet created on D'CENT Wallet

In the case of a XRP wallet created on a personal wallet such as D'CENT Wallet, there is no destination tag and only the address is created.
