In this tutorial you will learn how to prepare your ICO website on WordPress and how to sell erc20 tokens for Initial Coin Offering (ICO) on the Ethereum blockchain.
First of all, you need to familiarize yourself with a concept of Crowdsale. In a short, you need to develop and deploy a ERC20 ICO token and a Crowdsale contract to sell these tokens to your investors.
You can use the Crowdsale Contract and ERC20 Token Development Service to let us do this job for you.
The Crowdsale contract is a cornerstone part of any ICO campaign. The Crowdsale contract determines the logic of how to sell your erc20 tokens.
It is highly recommended to create a multisig wallet to store Ether collected and tokens minted. You can use this guide to create multisig wallet for example.
