I’ve tried many times to test deploying CrowdSale in Kovan test net.
There is no error until I see the Invest page, but keep showing "Transaction has failed when I click CONTRIBUTE to buy token.
I’ve tried create several contracts to avoid this error but still see the screen.
And I’ve found Total Supply amount is 0 in Etherscan… I set the supply value more than 1 but why it shows 0 always?
- Thank Victor for your help. (Sorry but I can’t reply to your reply again I don’t know why…)
And I’ve found the reason why I keep seeing the failure message.
It was because I checked Whitelist checkbox and never added whitelist addresses… so any other addresses are not possible to buy token. I think if the screen can check the White list option only when user added those addresses… it will be better for user’s understanding the failure reason.
