ERC-20 is a technical standard used for creating and issuing tokens on the Ethereum blockchain. It defines a set of rules that tokens must follow to ensure compatibility with wallets, exchanges, and other applications. This standard has made it easy for developers to create new tokens that can interact seamlessly within the Ethereum ecosystem.

ERC-20 ensures that tokens on Ethereum follow a common set of rules.
The ERC-20 standard specifies functions such as transferring tokens, checking balances, and approving transactions, allowing different tokens to behave in a predictable way across platforms. Because of this standardization, ERC-20 tokens can be easily integrated into wallets, decentralized applications, and exchanges without requiring custom code for each token. Many well-known cryptocurrencies and projects are built using ERC-20, making it one of the most widely adopted token standards. However, users must still be aware of risks such as smart contract vulnerabilities and token scams when interacting with ERC-20 tokens.
Short example:
Suppose a company creates a new token on the Ethereum blockchain using the ERC-20 standard.
This token can be stored in common Ethereum wallets and traded on exchanges that support ERC-20 tokens.
Because it follows the ERC-20 rules, it works seamlessly with existing platforms without requiring special integration.
