If you don't know how to deploy a Qtum node or don't know how to launch a Qtum wallet ,please refer to the following instructions:
- For command line users：《Guidance of Qtum Deployment》
- For GUI wallet users(common users)：https://eco.qtum.org/wallet
Important: After you encrypt wallet or change your pin code, please remember to backup your wallet again!!!
Please do all following things after you successfully installed and run a Qtum wallet:
qtum-cli command to encrypt wallet：
./qtum-cli encryptwallet "yourpassword"
yourpasswordis the user defined password, please remember it or you might lost your QTUM.
After encryption, all fund security related actions (like send QTUM, staking, or dump private keys) will all requiring a password.
Setting-Encrypt Wallet in the menu, as following:
create a new passphrase and repeat it. The wallet will restart after encryption.
After restart, there will be a lock flag shown on the bottom of the wallet, which means it is already encrypted (locked) ：
qtum-cli command to unlock wallet：
./qtum-cli walletpassphrase "yourpassword" 99999
the first argument
yourpassword is the passphrase you set when encryption, while the second is required unlock time, the unit is second (like 99999 seconds here).
After unlocking, you can send QTUM or do other fund security related actions.
If you only want to unlock the wallet for staking, please use ：
./qtum-cli walletpassphrase "yourpassword" 99999 true
The first two arguments are the same, and the 3rd argument
true means you only want to unlock for staking. After doing this, you can start staking, but other fund security related actions like sending QTUM or dumping private key still need your passphrase to fully unlock your wallet first.
Go to “Settings-unlock wallet” to unlock your wallet：
enter passphrase to unlock wallet. If you choose
For staking only, it means you only unlock the wallet for staking，but other fund security related actions like sending QTUM or dumping private key are still forbidened. So please unselect
For staking only if you want to fully unlock your wallet.
After unlocking, the lock flag on the bottom will switch to unlocked.
command for change passphrase:
./qtum-cli walletpassphrasechange "oldpassphrase" "newpassphrase"
oldpassphrase is the old passphrase you set last time，and
newpassphrase is the new passphrase you want set。
Go to “Setting-Change Passphrase” to change passphrase：
enter old passphrase and new one to complete modification：
