So for ICO, website need.
Basically it does ICO automatic coin distribution.
It should provide automatic system with account making, coin adding in exchange of user's deposit of Bitcoin, Ethereum, etc.
And dashboard, web wallet of that ICO coin.
For side feature, FAQ, contact support, calander function with coin buying cap and bonus rate schedule, etc.
Are there solution for this? Or all ICOs doing this job on their own with web developer?
The developer on its site already created it. They are working on themselves.
But are you looking for the platform to make automation to the ico?
That seems not to exist anymore.
But it becomes the responsibility to the developer to create its own infrastructure rather than pegged on 3rd party.
They are taking any responsibility to guarantee investor's money.
