Solidity for ICOs and Token Sales

Module 1: Blockchain 101

In this module, you will be introduced to blockchains, starting with a short history of blockchain technology. You will learn about the key concepts and components, including cryptography, keys, digital signatures, consensus algorithms (mining), transactions and blocks. At the end of this module, you will use JavaScript to implement a basic blockchain.

Module 2: Introduction to Ethereum

This module covers Ethereum and the Ethereum Virtual Machine (EVM). Master Ethereum fundamentals, including the different Ethereum networks, Wei and Ether, Gas Prices and Gas Limits, Smart Contracts and DApps.

Module 3: Transactions on Ethereum

In this module, you will create an Ethereum wallet using tools like MetaMask and MyEtherWallet. Receive your first Ether from a faucet, and make transactions, sending and receiving Ether between accounts. Learn how to monitor and read transactions using the block explorer Etherscan.

Module 4: Introduction to Smart Contracts

You start learning about Smart Contracts and how they work on the Ethereum network. Learn how contract immutability, storage and memory, gas prices and gas limits will affect contract design. You will use the smart contract development tool, Remix to write a Hello World contract in Solidity, then deploy the contract and interact with it.

Module 5: Solidity Fundamentals

Gain a deeper understanding of Solidity as you learn about contract structures, data types, functions, visibility, modifiers and events. Use your new skills to write a voting contract.

Module 6: Truffle Framework

In this module, you will learn about the various development tools for Solidity and setup your development environment for Truffle. You will learn how to write and perform tests, compile contracts and migrate them onto a network.

Module 7: Token Contracts

This module starts with an overview of Token contracts. Understand the mechanics behind token issuance and create your first basic token.

Module 8: ERC20 Token Standard

Learn about the ERC20 Token Standard, why there is a need for it and how it is being used in the real world. Understand the specifications, functions and events, then upgrade your basic token to make it ERC20-compliant.

Module 9: Crowdsale Contracts

Learn about Crowdsale contracts and how they are critical to Initial Coin Offerings(ICOs). Explore key components of different crowdsale contracts including Mintable vs Pre-minted tokens, Finalizeable contracts, Refundable Crowdsale, Token Vesting contracts, Multisig Wallets, Fallbacks, etc.

Module 10: OpenZeppelin Contracts Framework

In this module, learn about the OpenZeppelin Contracts Framework and why it is popular among ICO contracts. You will learn how to use the framework to implement your crowdsale.

Module 11: Smart Contract Security

Explore some of the known exploits and loopholes of Ethereum smart contracts then learn how to secure your own contracts.

Module 12: Development of ICO Smart Contracts

Putting together everything that you have learned, you will develop a set of Token and Crowdsale contracts for an ICO. Deploy your contract onto the Ropsten/Rinkeby network.

Module 13: Web3.JS Integration

Learn how to use the Web3.JS library and the Infura API to create a web-based dashboard for the purchasers of your tokens. The dashboard allows users to buy tokens, track their balances and view other information related to your ICO.
