Remember the frenzy that swept through the crypto world when Ethereum first launched? The ambiance crackled with eager anticipation, as the promise of a decentralized future glimmered on the horizon. We were on the cusp of a new era, where tokens were set to revolutionize finance, governance, and everything in between. Amidst this fervour, a pivotal moment arrived, the first-ever Ethereum token standard – ERC-20. 

From that point forward, the entire crypto ecosystem evolved dramatically, heralding the arrival of major milestones and new chapters in their development. In this blog, we’ll learn about some key Ethereum token standards, tracing their remarkable journey from humble beginnings to becoming the backbone of DeFi and digital ownership.

What are token standards? 

Token standards are the blueprints containing a set of agreed-upon rules that smart contracts must abide by. They define how tokens work and help guide their design, development, and operation on a given blockchain protocol. 

In the Ethereum world, these standards are known as Ethereum Request for Comment (ERC). Understand them as the foundational rules and specifications that all Ethereum-based tokens must follow.  ERC standards ensure interoperability and compatibility between different applications and wallets, encouraging a more interconnected ecosystem.

Ethereum Improvement Proposals, or EIPs, allow people to suggest potential upgrades, engage in proposal reviews, and participate in discussions. They encourage developers and community members to propose new solutions, protocol specifications, modifications, and features to the network. Think of ERC as a subcategory of EIP. 

Why did we even need Token Standards?

When Ethereum was in its nascent stage, it faced a situation. There was a lack of standardization. Each project developed its own token specifications, often resulting in fragmented ecosystems where tokens could not seamlessly interact with various platforms and dApps. This led to compatibility issues and inefficiencies. Developers recognized the necessity for a common framework (set of rules) to create, deploy, issue, transfer, destroy, and manage tokens on their underlying blockchain.

Initial Need for Token Standards

The early days of blockchain were marked by a lack of standardization, leading to compatibility issues and inefficiencies. As blockchain applications expanded, the need for a common set of rules became evident to ensure that tokens could be easily integrated into different systems. Token standards emerged as solutions to these challenges, providing guidelines for creating interoperable and secure digital assets.

Timeline of Key Ethereum Token Standards 

ERC-20 (2015)

  • Purpose: Established a pioneering standard for fungible tokens.
  • Benefits: Enables seamless interactions between tokens, wallets, and exchanges. 
  • Limitations: Limited to fungible tokens, lacking features for non-fungible assets.
  • Use Cases: Widely used for ICOs, utility tokens, and stablecoins like Tether (USDT).

ERC-721 (2017)

  • Purpose: Introduced a standard for non-fungible tokens (NFTs).
  • Benefits: Enables the creation of unique digital assets, ensuring ownership and provenance.
  • Limitations: More complex than ERC-20, not suitable for fungible assets.
  • Use Cases: Digital art, collectibles, gaming assets like CryptoKitties.

ERC-1155 (2018)

  • Purpose: A multi-token standard combining functionalities of ERC-20 and ERC-721 to support both fungible and non-fungible tokens within a single contract.
  • Benefits: Reduces transaction costs and improves efficiency.
  • Limitations: Complexity in managing mixed asset types.
  • Use Cases: Gaming, digital assets, and NFT marketplaces.

ERC-1400 (2018)

  • Purpose: A comprehensive framework for compliant security token issuance and management.
  • Benefits: Enhanced security, transparency, and integration with real-world assets.
  • Limitations: ERC-1400 can be complex to implement and  pose challenges for developers and issuers who are not familiar with securities regulations.
  • Use Cases: Ideal for enterprises tokenizing equities, bonds, and real estate.

ERC-777 (2020)

  • Purpose: Enhances ERC-20 with advanced features such as hooks for more complex interactions between tokens and smart contracts.
  • Benefits: Improves security and efficiency, reducing transaction costs.
  • Limitations: More complex implementation than ERC-20.
  • Use Cases: Financial applications requiring advanced transfer functionalities.

ERC-4626 (2022)

  • Purpose: Known as the Tokenized Vault Standard, it’s designed for standardized yield-bearing vaults.
  • Benefits: Optimizes yield farming.
  • Limitations: Still gaining traction in the ecosystem haven’t gone mainstream yet
  • Use Cases: DeFi applications and yield farming.

ERC-404 (Experimental)

  • Purpose: Combines fungibility and non-fungibility into a single standard.
  • Benefits: Unlocks new possibilities in fractional NFT ownership.
  • Limitations: Experimental and not yet standardized.
  • Use Cases: Fractionalized NFTs and innovative NFT projects

Benefits of Token Standards

  • Interoperability: Token standards ensure tokens can interact without friction across DApps and protocols on the same blockchain.
  • Reduced complexity for Developers: Adhering to established standards streamlines development, saving time and resources. It allows developers to focus on innovation.
  • Enhanced Liquidity: Standardized tokens are more easily listed on exchanges and integrated into wallets, increasing liquidity and accessibility for users.
  • Improved security: Token standards undergo thorough audits, reducing vulnerability risks and ensuring a safer and more secure environment.
  • Lower barriers to entry: Standardized tokens make it more manageable for new projects to penetrate the market and reach a broader audience.
  • Community and ecosystem support: Embracing popular standards connects projects with a broader ecosystem of tools, services, and community support, enriching their capabilities.

Successful Projects Utilizing Token Standards

  • Uniswap: A pioneering decentralized exchange that revolutionized token trading using ERC-20 standards.
  • CryptoKitties: A groundbreaking NFT project that captivated the world with its unique digital collectibles on the ERC-721 standard.
  • Decentraland: A virtual world pioneer that transformed digital real estate with ERC-721 land parcels.
  • Enjin: A gaming platform that leveraged ERC-1155 tokens to create immersive and interactive digital experiences.
  • SuperRare: A digital art haven that showcased the potential of ERC-721 and ERC-1155 standards for collectible NFTs.
