🚀Prerequisites
Understanding the prerequisites: Before diving into the complexities of ERC20 transfer() and safeTransfer(), it is good to establish a foundational understanding of a few key areas. This knowledge will serve as the bedrock for solidifying the content of this tutorial in its entirety. If you're still in the process of mastering these areas, don't be deterred. Take this opportunity to identify gaps in your knowledge and fill them over time - the learning journey is ongoing and cumulative.
To make the most out of this tutorial, it would be helpful to have a fundamental understanding of the following areas:
Blockchain Basics: A understanding of blockchain technology, including concepts like distributed ledger technology, decentralization, and consensus mechanisms, is crucial. Familiarity with how transactions are added to a block and how these blocks form a blockchain will also be beneficial.
Ethereum: As Ethereum is one of the primary platforms where smart contracts are used, knowledge of its structure, functioning, and specifically the Ethereum Virtual Machine (EVM) is essential. You should also be comfortable with the process of how transactions are conducted on the Ethereum network, including gas, gas prices, and transaction fees.
Smart Contracts: Familiarity with what smart contracts are, their use cases, and how they operate is vital. An understanding of how smart contracts interact with the Ethereum network and other smart contracts will be beneficial.
Solidity: Since we'll be dealing with code examples, a working knowledge of Solidity, the primary programming language used to write smart contracts on Ethereum, is required. This includes understanding the syntax, data types, and functions in Solidity.
ERC20 Tokens: Since fee-on-transfer tokens are a type of ERC20 token, understanding the ERC20 token standard is paramount. This should include knowledge of the standard functions defined in the ERC20 interface, such as
transfer()
