Key Features of the ERC20 Standard

Uniformity

Uniformity

ERC20 defines a common set of rules that all tokens must follow, making them interoperable with wallets, exchanges, and decentralized applications (dApps).

Simplicity-for-Developers

Simplicity for Developers

Developers can build tokens more easily without having to create new protocols for basic token functionality.

Wide-Adoption

Wide Adoption

The ERC20 standard is the most commonly used token standard on Ethereum, making it a default choice for creating fungible tokens.

Advanced Heading
An ERC20 token must implement the following key functions in its smart contract

Core Functions and Rules of ERC20

Total Supply

Specifies the total number of tokens in circulation.

Balance Of

Provides the balance of tokens held by a particular wallet address.

Transfer

Allows a user to send tokens directly to another user.

Approve

Permits another address (like a smart contract) to spend a specific number of tokens on behalf of the token owner.

Transfer From

Enables the transfer of tokens from one address to another through an intermediary (e.g., for automated transactions).

Allowance

Checks the remaining number of tokens an address is allowed to spend on behalf of another address.

Why-is-ERC20-Important

Why is ERC20 Important?

1

Interoperability

The standard ensures tokens can interact seamlessly across the Ethereum ecosystem.

2

Ecosystem Growth

The widespread use of ERC20 has created a massive ecosystem of wallets, dApps, and tools.

3

Efficiency

By following a common set of rules, developers don’t need to reinvent the wheel, reducing development time and errors.

The ERC20 standard is the foundation of thousands of cryptocurrencies and has played a critical role in the growth of decentralized finance (DeFi) and the blockchain ecosystem.
