  2. I try to change "/path/to/walletfile" by a private key of metamask account. Without success.

How can I make it works? Thx.

Solution

  • An easy way to do this is using your private key. In metamask click "account details" and "export private key".

    Then use Credentials.create("YourPrivateKey")
