DCENT X

In the DCENT phone app, enter the recipient address and amount, choose a network-fee level and tap Send to request a signature. X displays the network, transaction type, recipient address, amount and fee. Review those details on the device, scroll to the end and choose Confirm or Reject. Confirm leads to fingerprint or device-PIN authentication; after approval, the signature returns to the app for broadcast.

Confirm and Reject sit at the bottom of the scrolling transaction details, so they may be out of view when the screen first opens. The touchscreen handles navigation and data entry; the fingerprint sensor is on the right side of the device. X can hold two registered fingerprints, and its signing instructions also allow PIN approval. Initial setup registers the first fingerprint; the Later option skips adding a second.

Use DCENT Wallet version 10.0.0 or later and select “Biometric Wallet” on the app’s wallet-selection screen. Scan the connection QR code on the device to begin Bluetooth pairing, match the pairing codes and allow the connection on X. The QR code is a pairing step, rather than a way to carry a transaction between disconnected devices.

The current iPhone app requires iOS 15.5 or later; the current Android app requires Android 9 or later.

Android can connect through a USB data cable and synchronize accounts. The X sending guide, however, specifies Bluetooth for sending, so USB signing is not a confirmed buying option. The USB connection guide excludes iPhone. NFC is used with the R3covery backup card, separately from everyday transaction signing.

The standalone X offer contains the device and a USB-C-to-USB-C cable, without an R3covery card. DCENT’s current new-wallet setup starts with preparing that card separately, backing up to it, then viewing and verifying 24 recovery words on the touchscreen. Plan for the card before following that setup.

Write the 24 words in order and keep them offline, separately from the device. X has a 4–8-digit device PIN; the R3covery card uses a separate six-digit PIN. Restoring from the card requires that card PIN, and ten consecutive wrong attempts erase the card’s backup. The written words remain a separate recovery route.

For an existing compatible backup, X’s manual restoration accepts 12, 18 or 24 words, entered on its touchscreen’s grouped-letter keypad (T9). BIP39 is the recovery-word format used here. Another wallet can derive different addresses from the same words, so check its account and network rules and compare the restored addresses with the original ones.

After restoring from words or the card, re-add the coin accounts you used before and synchronize them with the app. If you used an additional passphrase, enter exactly the same passphrase afterward. The card backs up the default wallet’s recovery information; it does not store that extra passphrase.
