Building zwalletcli for WIndows

Windows 64bit (tested with Windows 11)

1. Installing msys2 from here.
2. Open MSYS2 MINGW64 shell from the windows start menu. The MINGW64 shell window will be similar to screenshot below.

1. Install the following libraries:

pacman -S base-devel git gcc make

1. Install clang, go for mingw64 and unzip

pacman -S  mingw-w64-x86_64-clang mingw-w64-x86_64-go unzip

Note: Restart mingw64 shell for Go to make changes.

1. Set environment variables

   export GOROOT=/mingw64/lib/go
   export GOPATH=/mingw64
   export PATH=$PATH:$GOROOT/bin
   
   # use clang as a default compiler for CGO
   go env -w "CC=/mingw64/bin/clang.exe"

2. Clone zwalletcli

git clone https://github.com/0chain/zwalletcli.git

1. Navigate to zwalletcli and run the following command :

cd zwalletcli
make install

1. Download necessary dll files as zip from here.
2. Unzip and copy dll's to zwalletcli directory. The zwalletcli directory will be available at the following path C:\msys64\home\<windows_username>\zboxcli if cloned under mingw64 shell.

3. Now run the ./zwallet command under zwalletcli directory .

./zwallet

On a successful build you will see a help section

Configure ZWallet network

Configuration for the Züs network by default is stored in network/config.yaml file of the zwallet github repo which we will copy to a new config.yaml file in our local system .

1. Open terminal and make a new .zcn folder in the home directory of your system using the command below:

mkdir $HOME/.zcn

Note: For windows create a folder named .zcn at `C:\Users\<windows_username>`path

1. Copy config.yaml from network directory in zwalletcli repo to .zcn directory.

cp network/config.yaml $HOME/.zcn/config.yaml

1. Open the config.yaml file located at $HOME/.zcn path of your system.The contents should be similar to the file below.

---
block_worker: https://demo.zus.network/dns
signature_scheme: bls0chain
min_submit: 50
min_confirmation: 50
confirmation_chain_length: 3
max_txn_query: 5
query_sleep_time: 5
# # OPTIONAL - Uncomment to use/ Add more if you want
# preferred_blobbers:
#   - http://one.devnet-0chain.net:31051
#   - http://one.devnet-0chain.net:31052
#   - http://one.devnet-0chain.net:31053

Zwallet connects to the Züs network using the block_worker field. These network details are automatically fetched from the blockWorker's network API. Preferred Blobbers are also present which you can uncomment for using specified storage providers for handling your files. Note: In case you are configuring zwallet network for setting up blockchain locally the block_workershould be set to http://198.18.0.98:9091/

Creating a Wallet

ZWallet CLI provides a long list of commands to use. Lets begin with creation of wallet on Züs decentralized network.

For creating a wallet using ZWallet. Simply run create-wallet command and this creates a wallet at default location~/.zcn/wallet.json

Sample Command

./zwallet create-wallet

Sample Output

wallet saved in /home/ubuntu/.zcn/wallet.json
{"client_id":"xxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"client_key":"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"keys":[{"public_key":"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"private_key":"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"}],
"mnemonics":"xxxx xxxx xxxx xxxxx",
"version":"1.0","date_created":"2023-05-03T12:44:46+05:30","nonce":0}

Here is a sample with faucet command which will create a wallet with test tokens at default location~/.zcn/wallet.json

To add tokens to the wallet run zwallet faucet command.

./zwallet faucet --methodName pour --input "new wallet"

Checking the wallet balance

To check whether the wallet is successfully created, verify the token balance in zwallet using

./zwallet getbalance

Note that by default zwallet checks balance for the wallet specified in wallet.json file located in the zcn folder in linux home directory.

Successful Response for ./zwallet getbalance command:

Balance: 1 (1.17 USD)
​

Getting tokens into the wallet

If getting Get balance failed.error when running ./zwallet getbalance command. Run the ./zwallet faucet --methodName pour --input "{Pay day}" command and then check the balance again.

The faucet command will get test tokens into the wallet for transactional purposes and make the wallet usable. Successful Response of the faucetcommand:

Execute faucet smart contract success

Now you have a wallet with available ZCN tokens, which can be used with 0chain blockchain and decentralized storage services.
