What is ERC20 Crypto Currency ERC20 is a type of cryptocurrency token built on the Ethereum blockchain. It is an Ethereum Request for Comment (ERC) that provides a standardized set of rules and functions that all Ethereum tokens must adhere to and include. ERC20 tokens are used to facilitate transactions within the Ethereum ecosystem, and they can be used to represent tangible goods, non-fungible tokens, or other digital assets and currencies. ERC20 tokens are commonly used to create and manage Initial Coin Offerings (ICOs) and for various other purposes within the Ethereum network.

What Makes It Unique ERC20 is unique in several ways. First, it is the most widely used and accepted set of rules for creating and managing tokens within the Ethereum network. By adhering to a standard set of rules, Ethereum developers can ensure that their tokens will be compatible with existing smart contracts and wallets. Additionally, ERC20 provides a standardized system for managing token transactions, which helps to protect investors and ensure a fair and secure trading environment.
