You can transfer balance from one key to another
comx balance transfer <key-name> <amount> <receiver-ss58address>
Or, if the receivers key is located on your disk
comx balance transfer <key-name> <amount> <key-name>
When staking a balance, you first have to pick a subnet id (netuid) and destination validator.
The staking command is defined as follows
comx balance stake <key-name> <amount> <validator-ss58address>
Similar to transferring if the validator key is already located on your disk you can use.
comx balance stake <key-name> <amount> <validator-name>
When unstaking a balance, you need to specify the subnet id (netuid) and the amount you wish to unstake.
The unstaking command is defined as follows:
comx balance unstake <key-name> <amount> <validator-ss58address>
You can also specify the name of the key, if it's located on your disk. Same as in transferring or staking.
