What are ERC20 tokens?
Since its launch in 2015, Ethereum has become one of the driving forces behind the growth of cryptocurrency. Initial coin offerings (ICOs) have raised billions of dollars in funding for crypto projects from all around the world, and most of these ICOs are based on the Ethereum platform. Buyers contribute Ether (ETH) or bitcoin (BTC) to participate in a crowdfunding sale, and in return receive some of the ICO project’s native tokens.
ERC20 is a technical standard for tokens issued on the Ethereum blockchain, providing a list of rules that all Ethereum-based tokens must follow. These include how the tokens can be transferred, how transactions are approved, how users can access data about a token and the total supply of tokens. The protocol is necessary to ensure compatibility between the many different tokens issued on Ethereum.
Just like bitcoin, Litecoin and any other cryptocurrency, ERC20 tokens are blockchain-based assets that have value and can be sent and received. The difference is that instead of running on their own blockchain, these tokens are issued on the Ethereum network. This means they’re hosted by Ethereum addresses and are sent using Ethereum transactions.

Want to know why they’re called ERC20 tokens? The “ERC” stands for “Ethereum Request for Comments”, which is an official protocol used to propose improvements to the Ethereum network. The “20” is the unique ID number used to identify the proposal.
