SmartContract ICO Crowdsale simple

Please read this post first: Issue your ERC20 token with Solidity on Ethereum Blockchain []

Similar with ERC20 token, now let create a ICO Crowdsale with simple abstract:

  • Start date : Tuesday, March 27, 2018 5:31:11 PM GMT+07:00
  • Bonus end date : Wednesday, March 27, 2019 5:31:11 PM GMT+07:00
  • End date : Thursday, March 26, 2020 5:31:11 PM GMT+07:00
  • Normal price : 100 NKEM Tokens per 1 ETH
  • Bonus price : 150 NKEM Tokens per 1 ETH

Some point difference with token here:

  • Init total supply is zero
  • Has time limit by start date and end date
  • Has price
  • Accept ETH transfer to contract. The price effect with bonus time, token total supply increase, send contract coin to sender, send eth coin to owner
