# Crowdsale (ICO Contract)

## What is Crowdsale? 

Crowdsale or ICO (Initial Coin Offering) is an analog of an IPO from the world of cryptocurrencies. This is the initial sale of the project tokens to a large circle of investors. 

After the purchase or after the end of the lock-up period, the issued cryptocurrency is distributed among investors in proportion to their deposits. ICO is a form of crowdfunding in the blockchain, in which participants finance the development of the company in return for the provision of project tokens.

Crowdsale passes through a special smart contract that accepts payments from investors for the purchase of tokens at a price set by the owner.

In CryptoDo, you can create your own Crowdsale contract and a web interface for the sale of tokens (ICO) without having to write code and understand the technology.

## Basic usage scenarios: 

1\. Attracting business investments. In this case, the tokens being sold will be an analogue of your company's shares.

2\. Crowdfunding. You can start collecting money from your audience in a convenient format to finance any initiatives.
