Getting Started

Building

1. Build on Ubuntu 2. Build on OS X 3. Build on CentOS7

Running

After building, the witness node can be launched with:

./programs/witnessnode/witnessnode --rpc-endpoint="127.0.0.1:8090" --max-ops-per-account=0 --partial-operations=true --data-transaction-lifetime=1

The node will automatically create a data directory including a config file. It may take several minutes to fully synchronize the blockchain.

After starting the witness node, in a separate terminal you can run cli_wallet:

./programs/cliwallet/cliwallet -s ws://127.0.0.1:8090

Set your inital password:

new >>> set_password <PASSWORD> locked >>> unlock <PASSWORD>

To import your wif_key(active key):

unlocked >>> importkey <ACCOUNT NAME> [<WIFKEY>] true

Import balances:

unlocked >>> importbalance <ACCOUNT NAME> [<WIFKEY>] true

Transferring Currency:

unlocked >>> transfer <FROM ACCOUNT> <TO ACCOUNT> 100 GXC "" true

If you send private keys over this connection, rpc-endpoint should be bound to localhost for security.

Use help to see all available wallet commands.
