# 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.cryptodo.app/smart-contracts/crowdsale-ico-contract.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
