Airdrop can be tested using the ERC20 contract. For testing run the test in ERC20.

Smart Contacts

Contains the implementations of the smart contracts for the tokenlab project, The implementation includes popular tokens like:

1. ERC20
2. ERC223
3. ERC644
4. ERC777

The implementation is based on the procedures defined by Openzeppelin, ConsenSys

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

Ganache-cli

ganache-cli is written in Javascript and distributed as a Node package via npm. Make sure you have Node.js (>= v6.11.5) installed.

npm install -g ganache-cli

For more information visit ganache-cli

Truffle Suite

Truffle is a development environment, testing framework and asset pipeline for Ethereum, aiming to make life as an Ethereum developer easier.

 npm install -g truffle

From there, you can run truffle compile, truffle migrate and truffle test to compile your contracts, deploy those contracts to the network, and run their associated unit tests.

Text Editor / IDE

You can use any Text Editor or IDE for the development of the smart contracts. Some of the poplars are:

• Sublime
• Atom
• Visual Studio Code
• Remix IDE

Development

Download the smart contracts into your local machine by using

git clone http://172.25.33.144/hamza/SmartContracts

Change directory to the contract you want to modify.

cd ERC<contract number>

Compiling

For Compiling contracts

truffle compile

Migration

For Migrating contracts

truffle migrate

Interacting

For interacting with the deployed contract use

truffle console

visit console for more information.

or

Use web3 for interacting the deployed contracts.

Working

There is a certain procedure in which contracts are deployed and one have to insure this procedure for proper working of the deployed token.

Balances should be deployed first and using the address of the balances contract Admin and HumanStandardToken should be deployed.

graph LR
balances --deploy--> deployed((Deployed))
deployed --address--> Admin
deployed --name, decimal, symbol, supply, address--> HumanStandardToken

Loading

To increase supply mint tokens only Admin can do that and Admin contract should be added to the Balances contract using setModule(address, true)

graph LR
Balances --1. setModule--> Balances
Admin --2. adminCreateTokens-->Balances

Loading

Testing

For testing smart contracts use

truffle test

For testing single contract or test file use

truffle test /< directory name >/ < filename >
