Advanced Solidity – Crowdsale of PupperCoin Token

A new start-up has decided to crowdsale their PupperCoin token in order to help fund the network development. This network will be used to track the dog breeding activity across the globe in a decentralized way, and allow humans to track the genetic trail of their pets. You have already worked with the necessary legal bodies and have the green light on creating a crowdsale open to the public. However, the start-up is required to enable refunds if the crowdsale is successful and the goal is met, and it is only allowed to raise a maximum of 300 Ether. The crowdsale will run for 24 weeks.

ERC20 token should be created and will be minted through a Crowdsale contract that can leverage the OpenZeppelin Solidity library.

This crowdsale contract will manage the entire process, allowing users to send ETH and get back PUP (PupperCoin). This contract will mint the tokens automatically and distribute them to buyers in one transaction.

It will need to inherit Crowdsale, CappedCrowdsale, TimedCrowdsale, RefundableCrowdsale, and MintedCrowdsale.

The crowdsale will be conducted on the Ropsten testnet in order to get a real-world pre-production testing.

应创建ERC20代币,并通过可利用OpenZeppelin Solidity库的众包合同进行铸造。



众包销售将在Ropsten testnet上进行,以获得真实世界的预生产测试。
