What is Ethereum Blockchain?
These self-executing agreements have their terms directly written into code and can interact with the Ethereum network. They play a vital role in the development of decentralised applications (DApps). Ether (ETH) is Ethereum’s native cryptocurrency, used as fuel for executing these Smart Contracts. Tokens on the Ethereum network represent assets, governed by different token standards that define their creation and functionality.
It is important to understand the distinctions and applications of each token standard within the Ethereum ecosystem. Each standard serves a specific purpose.
Prominent Ethereum Token Protocols
Let’s explore the four major Ethereum token standards and how they are used by the blockchain development company
ERC-20 Tokens These tokens are interchangeable and widely utilised in different financial applications and crowdfunding initiatives.
ERC-721 Tokens These tokens are a type of Non-Fungible Token that represent ownership of unique and indivisible assets. These tokens are commonly used in digital collectibles, gaming, and art.
ERC-1155 Tokens This standard combines elements from both ERC-20 and ERC-721. It empowers developers to effortlessly create tokens that can be either fungible or non-fungible, all within a single smart contract.
ERC721A Tokens They are a modified version of the ERC-721 standard, incorporating various enhancements to improve efficiency and versatility.
ERC-20 Tokens
What is the ERC-20 Standard?
Ethereum Request for Comment 20, i.e. ERC-20 is the most commonly used token standard on the Ethereum network. This set of rules and protocols is used by Blockchain developers to develop and execute tokens on the Ethereum Blockchain. These tokens, known as ERC-20 tokens, are interchangeable, meaning each token is indistinguishable from another of the same kind. This also allows users to hold fractional amounts by being divisible.
Use Cases of ERC-20 Tokens
ERC-20 tokens are used in various applications by blockchain development companies, including:
Cryptocurrencies Many popular cryptocurrencies like Chainlink (LINK), Binance Coin (BNB), and Tether (USDT) are ERC-20 tokens.
Fundraising Initial Coin Offerings (ICOs) often use ERC-20 tokens as a means to raise capital.
DeFi Decentralised Finance (DeFi) platforms use ERC-20 tokens for lending, borrowing, and trading.
Pros and Cons of ERC-20 Tokens
Pros of ERC-20 Tokens
Interoperability ERC-20 tokens can be easily integrated with a wide range of wallets, exchanges, and platforms. Accessibility The simplicity of ERC-20 makes it accessible for both developers and users. Liquidity High liquidity due to widespread use in the crypto ecosystem.
Cons of ERC-20 Tokens
Fungibility While beneficial in many cases for blockchain development services like interoperability, smart contract compatibility, crowdfunding & token sales, and more, fungibility can be a limitation when representing unique assets.
Lack of Standards ERC-20 tokens have varying levels of functionality, leading to inconsistencies in user experiences.
Vulnerabilities Poorly coded ERC-20 contracts can be vulnerable to hacks.
ERC-721
What is the ERC-721 Standard?
The ERC-721 standard, also known as the “Non-Fungible Token (NFT)” standard, was a major advancement in the Ethereum blockchain ecosystem. It was introduced to overcome the limitations of fungible tokens like ERC-20 and revolutionised digital asset creation by allowing for unique and indivisible assets.
At its core, the ERC-721 standard transformed the way we define ownership and value in the digital world. Unlike ERC-20 tokens, which are largely interchangeable, each ERC-721 token is unique, much like a digital snowflake. This uniqueness is what makes NFTs so influential and enables their widespread usage and innovative advancements.
Use Cases of ERC-721 Tokens
ERC-721 tokens have found application in:
Digital Collectibles CryptoKitties and NBA Top Shot are notable examples of digital collectibles represented as ERC-721 tokens.
Gaming NFTs are used in gaming to represent in-game assets like skins, characters, and weapons.
Art and Music Artists and musicians use NFTs to sell unique digital creations.
Pros and Cons of ERC-721 Tokens
Pros of ERC-721 Tokens
Ownership and Provenance - NFTs provide clear ownership records and provenance of unique assets.
Scarcity - NFTs are ideal for representing rare and limited-edition items.
Diverse Use Cases - The versatility of NFTs allows for applications in various creative industries.
Cons of ERC-721 Tokens
Limited Fungibility - The lack of fungibility can make ERC-721 tokens less suitable for certain financial transactions.
Scalability - High gas fees and network congestion can limit the efficiency of ERC-721 transactions.
Counterfeiting Concerns - Ensuring the authenticity of NFTs is a challenge.
ERC-1155 Tokens
What is the ERC-1155 Standard?
The ERC-1155 standard is a standout token standard in the Ethereum ecosystem. It offers blockchain development companies a versatile and adaptable toolkit for creating and managing tokens. What makes ERC-1155 special is its ability to combine the best features of both ERC-20 (fungibility) and ERC-721 (uniqueness).
In simple terms, ERC-1155 allows developers to create and manage multiple tokens using one smart contract. This not only improves efficiency but also streamlines the development process to provide a unified solution for different purposes.
Use Cases of ERC-1155 Tokens

Marketplaces - ER-1155 simplifies the creation of platforms that support various asset types.
Digital Collectibles - ERC-1155 Offers flexibility in representing both common and rare collectibles.
Pros and Cons of ERC-1155 Tokens
Pros of ERC-1155 Tokens
Versatility - One contract can manage a combination of fungible and non-fungible assets.
Efficiency - ERC-1155 can optimise gas costs by batching multiple token transfers in a single transaction.
Simplified Development - Developers have the flexibility to choose the appropriate token type within the same contract.
Cons of ERC-1155 Tokens
Complexity - The versatility of ERC-1155 can make the development process more intricate.
Compatibility - Not all wallets and platforms support ERC-1155 tokens.
ERC721A Tokens
What is the ERC721A Standard?
The ERC721A standard is a notable advancement in the world of non-fungible tokens (NFTs) and smart contract standards. It builds upon the foundation set by its predecessor, ERC-721, and introduces valuable improvements to enhance the functionality, usability, and overall efficiency of non-fungible tokens.
The introduction of batch transfer capabilities, royalty support, and enhanced metadata management tackles important challenges in the NFT space. These advancements aim to improve efficiency, prioritize creators’ needs, and cater to user preferences.

Future Trends and Developments of ERC Token
Three significant trends and developments in the world of Ethereum token standards include:
Cross-Chain Compatibility As the blockchain ecosystem continues to expand, there has been a growing need for cross-chain compatibility. This trend focuses on fostering interoperability between Ethereum and other blockchains, allowing assets like tokens to move seamlessly across different networks. With various chains offering unique features and capabilities, this compatibility becomes crucial in enabling efficient transfers of assets between different blockchain networks.
To achieve this, bridges and interoperability solutions are utilised. These bridges serve as connectors, linking Ethereum with other blockchains such as Binance, Smart Chain, Polkadot, or Solana. This enables assets to be securely transferred from one chain to another by locking them on one chain and issuing equivalent tokens on the target blockchain. For instance, tokens based on ERC-20 or ERC-721 standards in Ethereum can now be employed within these alternate blockchains, revealing a wide range of new use cases and facilitating broader adoption.
Fractional Ownership Traditionally, NFTs are indivisible and represent unique, often high-value assets like digital art or rare collectibles. However, fractional ownership platforms are now enabling investors to purchase fractions or shares of NFTs.
Regulation and Compliance Regulators and policymakers are taking notice of the rise in prominence of NFTs and blockchain assets. Regulation in the NFT space covers various aspects, including protecting consumers, preventing money laundering, and ensuring tax compliance. It is crucial to ensure that NFTs comply with legal and tax obligations in order to uphold credibility and legitimacy within the industry.
