It was a great help (ERC20 Contract is initialized now how do I set initial supply of tokens) and I manage to setup the token supply.
The next issue appeared when I try to send tokens to other address.
As shown, the error says “Fail with error ‘whenNotPaused’”.
I am not sure what is this error and how to fix that.
The other error I notice in truffle console is “'Error: nonce too low”.
I am looking into the document and I hope to find the solution.
