ERC20 Token Sales with Whitelisting Feature
I think the Initial Coin Offering (ICO) is the first use case every Solidity developer need to get familiar with even the ICO mania is behind us.
The token known as
Fluwix with symbol
FWX, as I assumed whatever I learned here will be integrated into another project of the same name in the future. The exchange rate of
FWX is 1 to 1. For example, for 0.001 ETH you will get 0.001 FWX in return.
The project is created by referred to an excellent tutorial published by Thomas Wiesner. The key feature of the project is whitelisting. Only the address of user accounts being whitelisted by the owner (the deployer of the contract) can buy the token.
The project is using the following third party libraries to simplify codes:
@email@example.com implementation of ERC20
- Reuse the code of Crowdsale.sol from
@firstname.lastname@example.org writing unit tests.
The dApps is interacting with smart contracts running on Rinkeby testnet, hence you need some ETH in your wallet. If you don’t have any, you can request some ETH from Rinkeby Faucet.
If you are interested to look into the code and run it in your local machine, please check out the git repository hosted at https://github.com/limcheekin/eth-erc20-token-sale. Feel free to fork the repository and send me pull request.
I hope to hear from you soon! :)
