This is my first post on Binance Square, and I hope everyone will support me!
Most tutorials on ERC20 start by listing six functions for you to memorize, which can be quite confusing. In fact, if we set aside the complex terminology, the logic behind these six functions is quite easy to understand—they are derived from the actual scenarios in which we use tokens.
These six functions are not designed out of thin air: from the basic scenario of 'fixed total supply → check balance → direct transfer' to the third-party scenario of 'authorization → proxy transfer → check remaining quota,' they cover all the core needs for token circulation. Missing one creates a vulnerability, adding one makes it redundant; the design follows the logic of 'what is needed for actual token use determines what functions are designed.'
The essence of technical standards is to turn daily operations into executable rules, and when you think about it this way, ERC20 is really not complicated at all.
By the way, I am currently open to work, and I welcome all the big daddies and mommies to take me away!
