ERC-20

ERC-20 is a standard protocol for creating and managing tokens on the Ethereum blockchain. It defines a common set of rules—such as how tokens are transferred, how to check balances, and how to approve others to spend tokens—ensuring compatibility across various applications and wallets. This standardization makes it easier to develop, trade, and integrate tokens, enabling a vast ecosystem of digital assets like currencies, utility tokens, and project funds within the Ethereum network. Essentially, ERC-20 acts as a blueprint that ensures all tokens following it work seamlessly together.
