If you are not running the Qtum node, please install the Qtum wallet by following the following tutorial:

  • Command line user Reference: How to Deploy Qtum Quantum Chain Nodes
  • Graphical wallet can be downloaded here: eco.qtum.org/wallet. Please refer to Qtum PC Wallet Using Tutorial for its usage.

After encrypting your wallet or changing your password, be sure to back up your wallet again!

After installing and running the wallet, proceed with the following steps:

Lock the purse

Command line user

The command to lock the wallet is:

./qtum-cli encryptwallet "yourpassword"
Copy the code

Yourpassword is the user – defined password. Please remember your password!

For example, if you want to set the password to test1234, run the following command:

./qtum-cli encryptwallet "test1234"
Copy the code

After the lock, all funds security related operations (such as sending QTUM and dumping private keys) need to be unlocked before they can be executed.

The PC version of the wallet

On the menu bar, select setting-encrypt Wallet

Enter your password and confirm. The wallet will restart after successful setup.

After the wallet is restarted, the lock symbol will be displayed in the lower right corner, indicating that the wallet is locked:

Unlock the purse

Command line user

To unlock the wallet, run the following command:

./qtum-cli walletpassphrase "yourpassword" 99999
Copy the code

The first parameter yourPassword is the password you set earlier; The second variable is the time to unlock, in seconds.

For example, if you want to unlock the test1234 password for 1000 seconds (the password will be automatically locked again after 1000 seconds), run the following command:

./qtum-cli walletpassphrase "test1234" 1000
Copy the code

After unlocking, you can normally send QTUM or carry out other funds security related operations.

To unlock mining otherwise, use the command:

./qtum-cli walletpassphrase "yourpassword" 99999 true
Copy the code

The meanings of the first two parameters remain unchanged, and the last parameter true indicates that only the mining function is unlocked. After the command is used to unlock the wallet, mining can be normal, but other operations related to fund security are still prohibited, and can be used only after the wallet is fully unlocked.

The PC version of the wallet

Select settings-unlock Wallet:

Enter your password to unlock your wallet. A box For staking only, if checked, unlocks mining, and mining is normal, but a password is required to send QTUM otherwise. If this parameter is not selected, the account is fully unlocked.

After the wallet is unlocked, the lock symbol at the lower right corner of the wallet interface becomes open.

Change the password

Command line user

To change the password, run the following command:

./qtum-cli walletpassphrasechange "oldpassphrase" "newpassphrase"
Copy the code

The first parameter oldpassphrase indicates the old password, and the second parameter newpassphrase indicates the new password.

For example, if the previous password is test1234 and you want to reset it to 12345678, run the following command:

./qtum-cli walletpassphrasechange "test1234" "12345678"
Copy the code

The PC version of the wallet

Select setting-change Passphrase to Change the password:

Enter the old password and the new password to complete the change:
