Cryptos have fundamentally altered our perspective on digital assets and transactions. One of the most common ways to create and manage tokens on the Ethereum network is via ERC20 tokens. Theirs is only one of many fresh perspectives on blockchain technology. What is ERC20 token?
We’ll explain what is ECR-20? where they came from, how they function, how significant they are, the benefits and drawbacks of using them, and then provide you with a list of the top ERC20 currencies. Join me as I delve into the fascinating realm of ERC20 currency.
What is ERC-20?
A well-known way to make tokens on the Ethereum system is to follow the ERC-20 standard, “Ethereum Request for Comments 20.” This document lays out a simple set of rules that developers can use to create ERC-20 coins that can be used on Ethereum.
In its basic form, ERC-20 is a set of rules that all smart contracts on the Ethereum blockchain must follow in order to use coins. The token standard sets out a common set of rules that every Ethereum token must follow. This lets writers program how new tokens will work in the Ethereum environment.
ERC-20 makes sure that Ethereum tokens behave consistently across the platform. This makes it easy for developers to guess how tokens will interact with each other.
The history of ERC-20
The idea for the standard came from Fabian Vogelsteller, a blockchain developer and thought leader, in late 2015. He sent the suggestion for the standard through the project’s GitHub page. It was given the number ERC-20 because it was the twentieth response.
As of September 2017, the standard was accepted as an Ethereum Improvement Proposal (EIP). It then gave developers a global code standard, which made it easier to work with different projects and apps and let them connect more.
How does ERC-20 work?
The ERC-20 standard includes a list of features every ERC-20 token smart contract must have. Some of these basic functions include moving tokens from one address to another, checking an address’s token amount, and permitting addresses to spend tokens on behalf of the token user.
When these tasks are followed, any wallet or smart contract that works with ERC-20 tokens can easily recognize and deal with them.
ERC-20 also lists two things that must happen for trades to be valid. Some of these are Transfer, which is called whenever a token is moved, even if it has no value, and Approval, which is called whenever an approval code is called.
As long as all ERC-20 tokens follow the same rules, they will always work the same way with decentralized apps (dApps), exchanges, wallets, and other tokens. So, developers don’t have to make a separate case for each ERC-20 token when making apps because they know exactly how any ERC-20 token will work in those apps.
ERC-20 tokens can also be managed by smart contracts, which makes it possible to do complicated things like giving tokens out from a decentralized autonomous organization (DAO), keeping track of tokens in a decentralized application (DAA), or setting up a decentralized market where tokens can be bought and sold.
How to Create an ERC-20 Token
To make an ERC-20 token, you need to write a smart contract that handles the usual events and tasks. Developers have to decide how many coins will be made, as well as their name, symbol, and other features. The tokens can be given to users and sold on different platforms once the smart contract is made and put into the Ethereum network. Here is a quick list of the steps.
Step 1: Describe Your Token’s Description
Step 2: Collect your tools for development
Step 3: Draft the Smart Contract
Step 4: Create the Smart Contract
Step 5: Deploy the Smart Contract
To make making ERC-20 coins easier for people who don’t know how to code, there are also tools and sites available. These services have easy-to-use interfaces that let people make and use tokens without having to write any code.
ERC-20 Tokens
Tokens that are made with the ERC-20 standard are called ERC-20 tokens. The Ethereum blockchain is used to build and run these coins. This lets them take advantage of Ethereum’s large and successful decentralized finance (DeFi) environment.
These tokens can stand for many things, from cryptocurrencies to utility tokens to digital copies of real-world assets like gold or real estate.
It’s important to note that all ERC-20 coins share the same features and controls. This makes it easy for them to work with other wallets and contracts compliant with ERC-20.
Also, these tokens are fungible, meaning they can be used in place of each other and have the same value. On the other hand, non-fungible tokens (NFTs) follow the ERC-721 and ERC-1155 standards and are unique, with prices that change over time.
How do I get an ERC-20 wallet?
A digital wallet that works with Ethereum and its coins, especially those that follow the ERC-20 standard, is called an ERC-20 wallet. People can store Ether, the Ethereum blockchain’s original coin, and also handle and trade ERC-20 tokens with this type of wallet.
Some popular wallets that work with ERC-20 are Trust Wallet, MetaMask, MyEtherWallet (MEW), Ledger Nano S and X (hardware wallets), and Trezor (in addition to the ones listed above). These wallets’ interfaces, protection features, and other features differ.
Use Cases of ERC-20 Tokens
ERC-20 coins have allowed many different blockchain apps and use cases to happen.
Here are a few well-known ways that ERC-20 coins are used.
1. Decentralized Finance (DeFi) Platform: ERC-20 tokens are used in DeFi platforms for transfers, control, stake, and loan collateral.
2. Stablecoins: These are an ERC-20 token whose value stays stable by being tied to a safe object like gold, the US dollar, or other foreign currencies.
3. Utility Tokens: ERC-20 tokens can be used as utility tokens to access a blockchain-based product or service. People can use them to buy services, get benefits, or talk to DApps built on the Ethereum network.
4. Governance Tokens: In autonomous groups and protocols, governance tokens give their owners the power to make big decisions that affect the project’s growth. These decisions include system updates, resource sharing, and changes to the rules for governance.
5. Security Tokens: Because of rules about regulation, security tokens are not as popular as utility tokens. However, some ERC-20 tokens reflect ownership in real-world assets like stocks, bonds, or real estate.
6. Non-Fungible Tokens (NFTs): Because NFTs can’t be changed into other currencies, they are mostly linked to the ERC-721 and ERC-1155 standards. However, ERC-20 tokens have been used to split control of NFTs.
7. Reward and Loyalty Programs: Businesses and projects can create ERC-20 tokens as part of reward and loyalty programs. Users earn tokens by participating in the ecosystem, like buying things, sharing content, or doing things with the community.
8. Fundraising and ICOs: ERC-20 coins have often been used for ICOs, a way for new projects to get money from investors by selling tokens.
Pros and Cons of ERC-20
The ERC-20 standard has unique pros and cons for makers and people who use it.
Pros:
- Standardization makes it easier to make tokens and makes sure they work with other tokens.
- Interoperability with Ethereum’s ecosystem improves functionality.
- Easier integration with wallets and exchanges.
- Wide adoption within the Ethereum community.
- Important for the growth of decentralized finance (DeFi).
Cons:
- Smart contracts can be broken, which can lead to security issues.
- Ethereum’s scalability problems can slow down and cost more for transactions.
- Most tokens don’t have any underlying assets, which makes them very volatile.
- Uncertainty about regulations can make it hard to follow them.
- Too many tokens can make it hard for people to understand them, which raises the risk of scams.
Alternative Standards
The ERC-20 standard’s success in making it easier to create and trade fungible tokens on the Ethereum blockchain has led to several complementary token standards. Each one is meant to fill in the gaps left by ERC-20 or add new features. Here are some well-known alternatives:
1. ERC-721 (Non-Fungible Tokens)
One-to-one exchanges between non-fungible tokens (NFTs) were made possible by ERC-721. Each NFT is unique and cannot be swapped for another token. When you compare this to ERC-20’s fungible tokens, each token is the same as the others.
This token standard is used for digital art, event tickets, real estate, digital collectibles, and more that must be unique and show where they came from.
2. ERC-1155 (Multi-Token Standard)
Enjin created ERC-1155, which lets you make fungible and non-fungible tokens within the same contract. This makes transfers and storage better for more complicated token use cases.
It’s especially helpful in collectibles and games where one contract might control different items, like money, guns, and armour, each with its properties.
3. ERC-777 (Advanced Token Standard)
A better version of ERC-20 has more advanced features, such as hooks that let tokens respond to being sent or received. ERC-777 tries to fix some of the problems with ERC-20 by making transactions safer and letting you do more complicated things with tokens.
It’s made for advanced financial apps and services in the DeFi environment that need tokens and other smart contracts to connect more.
Future of ERC-20 Tokens
The future of ERC-20 coins is closely tied to how the Ethereum blockchain changes over time, as well as to technological progress, changes in regulations, and changes in the cryptocurrency and blockchain worlds as a whole.
ERC-20 is one of the most popular standards for making tokens on the Ethereum platform. It has been key to building a healthy community of digital assets, decentralized apps (DApps), and financial tools.
ERC-20 tokens look like they will have a bright future, with the possibility for huge growth. It could be said that this coin standard has already solidified its place as an important part of DeFi on the Ethereum network.
