1. Generate wallet address

1. Download the wallet

CKB currently only has a command line wallet. To generate the wallet address through the command line, first download the wallet from the link below.

Official GitHub: https://github.com/nervosnetwork/ckb/releases.

Choose the wallet version according to your own system. The following takes Windows system as an example, and download “ckb_v0.19.2_x86_64-pc-windows-msvc.zip” for Windows 64-bit system.

2. Enter the decompressed wallet folder through cmd and run the wallet

After the wallet has been downloaded, unzip it, and enter the unzipped wallet folder through cmd. Note: Chinese cannot be used for folder naming.

For example, store the decompressed folder ckb_v0.18.0_x86_64-pc-windows-msvc (not renamed) on the desktop, and the path is C:UsersrayDesktopckb_v0.18.0_x86_64-pc-windows-msvc ( If it is saved in another folder, the folder path can be obtained from the following location, and there cannot be Chinese in the path).

Hold down the “Windows+R” key, enter cmd, click “OK” to run cmd. Take the above path as an example, follow the steps as follows, and press “Enter” to confirm each time you enter a command:

1) Input c: (Enter the designated drive letter, if the folder exists in drive D, input d:).

2) Enter dir (view files and folders in the current directory).

3) cd+space+folder name (view the specified folder directory).

To consult the specified folder directory, you can enter cd+space+folder name to open in sequence, and click enter after each input.

Also take the above path as an example to proceed as follows: cd desktop and press Enter to enter the desktop

Then enter cd ckb_v0.18.0_x86_64-pc-windows-msvc and press Enter to enter the target folder.

As shown below.

4. Export the wallet private key enter

ckb-cli account export –lock-arg 411d4db46eb6909f662309d43e312d7d6f814257 –extended-privkey-path privkey.

You need to replace the string of numbers after lock-arg with the lock_arg you just generated.

Enter the password you just set such as 123456, and then a privkey file will be generated locally, which contains your private key (first line) and the chain code for generating the hardware wallet (second line).

At this point, the wallet has been created.
