What are ERC standards?

A document called an “Ethereum Request for Comments” (ERC) is created by smart contract programmers who use the  Ethereum blockchain platform. They lay out the principles that Ethereum-based tokens must follow in these documents. The Ethereum community reviews these papers using a method known as the “Ethereum Improvement Proposal (EIP).” After going through the EIP (Ethereum Improvement Proposal)


process, the Ethereum community approves some of these reports, finalizes them, and developers adopt them. Moreover, Learn about all like What are Ethereum standards: ERC-20, ERC-721, ERC-1155.

An Ethereum Improvement Proposal (EIP) is a design document that informs the Ethereum community or describes a new function for Ethereum, its systems, or its ecosystem.

What are ERC-20 standards?

ERC-20 tokens are a collection of similar tokens with the same set of properties. They adhere to the ERC-20 standard, which establishes a set of guidelines for the development and management of fungible tokens. The use of ERC-20 tokens allows for the development of micro-economies with liquid markets for a variety of applications.

Fabian Vogelsteller proposed the ERC-20 (Ethereum Request for Comments 20) Token Standard in November 2015. It is a Token Standard that implements an API for tokens within Smart Contracts.
It includes features such as the ability to move tokens from one account to another, as well as the ability to see an account’s current token balance and the overall availability of the token available on the network. It also has several other features, such as approving the use of a certain amount of token from one account by a third-party account.

Trading ERC-20 Tokens

ERC-20 tokens may be exchanged on a variety of websites, including:
● Regular exchanges
● Decentralized exchanges
● The automated liquidity pool can facilitate smooth token swapping by utilizing Automated Market Making algorithms to decide the price of purchasing ERC-20 tokens.

ERC-721 Standard

Each ERC-721 token is associated with its own collection of properties and values. Being one of a kind increases the value of ownership, particularly in the case of highly sought-after tokens. The ERC-721 protocol is a standard that must be implemented for any smart contract that produces ERC-721 tokens.

NFTs can be interacted with using a variety of features, including:
● Identifying the ERC-721 token’s owner address
● Approval of an ERC-721 token transfer. Each address to which we want to transfer must be accepted before the transfer can begin.
● Checking an ERC-721 token’s accepted addresses.

● ERC-721 Token Transfer

Trading ERC-721 Tokens

ERC-721 tokens can be exchanged for other tokens or Ether in the same way that ERC-20 tokens can.
Automated Market-Making algorithms are not possible to apply since all ERC-721 tokens have unique properties.
At the moment, the agreed method of trading them is to auction or exchange them on NFT-specific peer-to-peer marketplaces, the main of which is OpenSea.

This generates new economies for digital collectibles, as well as remarkable figures for a new form of asset:
● The top three types of NFTs have a trading rate of over 1,000 Ether in a single day.
● Another VR simulation, Decentraland, has a total volume of 44,000 Ether divided among 3,662 owners. This equates to a 12 Ether average possession of the LAND estate.
● An F1 gaming object worth 415.9 Ether was the most expensive NFT offered in 2019

ERC-1155 Tokens

The ERC-1155 token is a type of regular token that can store tokens that can behave as ERC-20 or ERC-721 tokens or both at the same time, under its authority.
Witek Radomski, Andrew Cooke, Philippe Castonguay, James Therien, Eric Binet, and Ronan Sandford created this standard.

New functions and possibilities of the ERC-1155 token are:
● Mass transfers as standard
● Multiple tokens in the same contract
● Integrated token type detect

  • Secure token transfer
