Why Does the “An Error Has Occurred” Message Appear When Sending Coins? / Why Can’t I Sign a Transaction in My Wallet?

DCENT Wallet is a non-custodial wallet that securely stores your private keys, allowing you to manage your blockchain assets directly.

When sending a coin, an error message such as “An error has occurred” may appear if the transaction fails to be properly processed during its broadcast to the blockchain network. This can happen due to issues with the network or other unexpected conditions during the transaction process.

In addition, if you are using DCENT X or a Biometric Wallet, an error may occur if the wallet connection has been disconnected or if there is a firmware version issue; if you are using a DCENT S / All-in-One Card Wallet, an error may occur if the card was not tagged (NFC) properly.

[Common Causes]​

  • Blockchain network congestion or temporary node failures
  • Insufficient gas fees or incorrect fee settings
  • Poor mobile data or Wi-Fi connection
  • Issues on a specific blockchain network
  • Wallet connection disconnected or firmware version issue when using DCENT X or a Biometric Wallet
  • Card not tagged (NFC) properly when using a DCENT S / All-in-One Card Wallet

[How to Troubleshoot]​

  1. Completely close and reopen the DCENT app
  2. Check whether the DCENT app is updated to the latest version
  3. Check your network connection (Wi-Fi or mobile data)
  4. Check if sufficient gas fees are available
  5. If you are using DCENT X or a Biometric Wallet, check the wallet connection status and update to the latest firmware version (for a DCENT S / All-in-One Card Wallet, tag the card again)

After checking all of the above, please try the transaction again under the same conditions.
