What is ERC20 (ERC20)

ERC20 is a protocol standard that defines specific rules and standards for issuing tokens on the Ethereum’s network. The majority of tokens issued on the Ethereum blockchain are ERC-20 compliant. It allows one token to be traded with another.

ERC20 (ERC20) features

ERC-20 (Ethereum Request for Comments) is a formal Ethereum Improvement Proposal that was adopted as a smart contract token standard on the public blockchain. Initially proposed by developer Fabian Vogelsteller, ERC-20 has ballooned to encompass a series of narratives, from powering the ICO fundraising method and craze of 2017 to underscoring the potential of standardized protocols in public networks.

At a high level, Ethereum is a public blockchain network for building decentralized applications (dapps) using smart contracts, which are written in the programming language Solidity. Ethereum has a native cryptocurrency called Ether (ETH), which is used for transferring value on the network and paying gasfees, which are required to cover the costs of computation across the network and prevent spamming.

However, the existence of smart contracts on the network, which are ostensibly autonomous accounts and computer programs, enables a suite of new functionality in Ethereum not available in Bitcoin. Ethereum is a Turing-complete platform, meaning that virtually any logic can be programmed into applications on the network. Smart contracts are accounts that execute functions automatically on the network, and a group of smart contracts coalesced into a broader purpose form dapps (Decentralized applications).

To facilitate communication and the development of functional, interoperable dapps and smart contracts, a framework for standardized smart contracts for tokens was created. The most prominent of which is ERC-20.

ERC-20 is a standardized format for the creation, issuance, and management of fungible tokens on Ethereum. These tokens have different use cases and applications, such as utility tokens, and are created by developers using ERC-20 as a reference. The standard provides basic formats for transferring and interacting with ERC-20 tokens, which are subsequently used by various wallets to enable the storage, transfer, and management of the tokens.

Standardization leads to rapid innovation and underscores the Internet’s design.

With ERC-20, projects can trivially create and issue tokens for use within various dapps as incentive structures or fundraising vehicles. Notably, ERC-20 is at the basis of the Initial Coin Offering (ICO), a vehicle for raising funds directly in cryptocurrency to fund a project, such as a dapp on Ethereum. ICOs raised $6.3 billion in 2018, and the unique crowdfunding method connects users and investors directly to projects.

ERC-20 tokens are designed to be fungible, which means that each token unit is equivalent to the next. For example, using the Maker DAO ERC20, 1 MKR is always equivalent in value to 1 MKR.

The combination of ERC-20’s standardized technical format and ballooning network effects have caused the standard to become widely adopted on Ethereum. Most tokens on the network are ERC-20 compatible and can be seamlessly exchanged and transferred for one another on the network. Most of the Ethereum-related tokens you will find on coin aggregation sites are ERC-20 tokens, like Maker, Dai and Augur REP.

Importantly, ERC-20 tokens have broached broader conversations in the cryptocurrency sector about the role of standardized protocols and contracts in improving innovation and interoperability. As blockchains progress towards being able to port value and data between each other, the standardization of protocols lays at the heart of the discussions.

Besides ERC-20 on Ethereum, several other standards emerged (i.e., ERC-721) that focus on different types of tokens, such as non-fungible. These non-fungible tokens are designed to represent unique digital assets, like a virtual cat, with the rise of CryptoKitties becoming the flagship example of what non-fungible tokens can accomplish.

The overall impact of ERC-20 has been the growth of an ecosystem of assets, dapps, and innovations (i.e., DeFi) on Ethereum. The popularity of ERC-20 as a token standard has shed a light on the potential for further extending standardization into public blockchains, and the industry is only at the beginning of cracking its full potential.

It is important to remember that ERC-20 tokens, although built on Ethereum, are tokens that exist within ecosystems on the network, like dapps.
