6 Steps to ERC20 Tokens and ICO Smart Contracts Tutorial Code

The following Code if for the tutorial:

6 Steps to ERC20 Tokens and ICO Smart Contracts: In depth step by step

The is a simple ERC20 token with ICO functionality built into the contract. Once deployed, to begin the ICO the owner of the contract has to call the startICO() function. The contract will not automatically end the ICO, This must also be done by the owner of the contract by calling the finalizeIco() function. If all the Tokens that are part of the sale have been sold or if someone sends more Ether then remaining tokens, the contract will send any remaining tokens to the sender, calculate the difference in Ether and return the remaining balance. The rest will be sent to the contract owners address just like a regular token purchase.

This code does not allow for discounts or bonuses, but any half competent developer should be able to quickly and easily add them in or any other functionality if desired. The contract will continue to function as a Simple ERC20 Token even during the ICO.

NOTE: There is nothing built into this contract to prevent someone from buying tokens and listing them directly onto an exchange. If you would like to prevent this feel free to combine the token with the pauseable token code which can be found here:

Prerequisites

Understanding of Solidity or proficient with a language like JavaScript, Swift, Java etc. Or just follow along with my tutoral at:

6 Steps to ERC20 Tokens and ICO Smart Contracts Tutorial Code

Deployment

• Make sure that you have an ERC20 compatible Ethereum wallet.

• To execute the token code:

  • For MyEtherWallet;
    1. Copy the token code and its dependencies.
    2. Paste the token code into the remix online compiler.
    3. Copy the EVM code and past into the MyEtherWallet execute smart contract.
    4. Pay the gas price, enjoy your tokens.
