Each Section is in order of the layout of an ERC20 token. By following this, you should achieve the knowledge to create an ERC20 token.
- Basic understanding of blockchain concepts and Ethereum.
- Familiarity with programming concepts (e.g., variables, functions, loops).
- What is Solidity?
- Solidity's role in Ethereum smart contracts.
- Setting up the development environment (Remix, Truffle, or Hardhat).
- Understanding the "pragma" statement and its purpose.
- Importing other Solidity files and using libraries.
- Introduction to interfaces and their significance.
- Creating an interface for ERC20 tokens.
- Defining a Solidity contract and its structure.
- Contract constructor and fallback functions.
- Exploring state variables and their usage.
- Commonly used state variables in ERC20 tokens (e.g., "mapping", "balances").
- Creating a constructor for contract initialization.
- Initializing state variables during deployment.
- Implementing ERC20 standard functions:
- balanceOf
- transfer
- transferFrom
- approve
- allowance
- Understanding function modifiers like view and pure.
- Adding Taxes
- Using events to emit information from the contract.
- Subscribing to events from the front-end.
- Differentiating between internal and external functions.
- Implementing internal helper functions for ERC20 operations.
- Understanding the role of modifiers in Solidity.
- Creating custom modifiers for access control.
- Implementing other optional ERC20 functions like:
- totalSupply
- decimals
- Adding custom functionality to the ERC20 contract.
- Common vulnerabilities and how to avoid them (e.g., reentrancy, integer overflow).
- Utilizing OpenZeppelin's Solidity library for secure contracts.
- Deploying the ERC20 contract on a test network (e.g., Rinkeby).
- Interacting with the contract using Remix or a custom front-end.
- Applying the knowledge gained to build a decentralized application (DApp) that uses ERC20 tokens.
- Inheritance and contract structuring.
- Upgrading contracts using proxy patterns.
- ERC20 token extensions (e.g., ERC721, ERC1155).
- Recap of the course.
- Guidance on further learning and exploration in Solidity.
