The Ethereum network changed the paradigm of the blockchain sphere not only with its capacity of smart contracts but also due to introducing a flexible standard for tokens called ERC 20. This threshold became an essential factor for the emergence of dApps, ICOs, and the Blooming DeFi space. Since its application, ERC-20 has been a primary contributor to the development of the blockchain economy. In this article, we will describe the history of ERC 20 tokens, their evolution, current usage, and potential development.
The Birth of ERC-20 Tokens
The term ERC-20 is an acronym that refers to the ‘Ethereum Request for Comments’ #20 which was first introduced by Fabian Vogelsteller in the year 2015. This proposal established a common set of rules for tokens that are issued over the Ethereum network enabling easy development of new tokens on the Ethereum blockchain.
Earlier Erc20 tokens had different codes and interfaces which was cumbersome because of means of linking other assets. This problem was addressed by Erc20 which set forth the requirements that compliant tokens must adhere to, such as:
Total Supply: provides the number of total tokens in circulation.
Balance Of: provides the balance of a given address.
Transfer: moves a specific amount of tokens from one account to another.
These standards and solutions in place saw the rapid growth of the ICO season in the year 2017 where companies were able to raise billions of dollars through the sales of tokens. Over the past several years, ERC-20 has turned into the widespread standard for creating new digital currencies and as a result Nexus is the most popular platform for issuing tokens in the market today.
In parallel with the expansion of the market for ERC-20 tokens, the appearance of developed Top ERC-20 Token Development Companies has also taken place. These companies focus on the development and implementation of custom ERC-20 tokens for startups, businesses, and other blockchain initiatives. These companies have played a vital role in the development of the token economy by helping startups and large enterprises in the creation of their own digital currencies.
The Present: ERC-20 in the Modern Crypto Space
The ERC-20 token standards are a vital part of the DeFi ecosystem, facilitating lending, borrowing, staking, and liquidity pools – or, as one might say, the Four Pillars of DeFi. Here are the changes brought by the ERC 20 Token in the implementation of blockchain technology: Defi Boom: Most DeFi projects involved the use of ERC-20 tokens. Uniswap, Aave, Compound are some of the platforms that allow the use of ERC-20 for liquidity, governance and utility purposes where members can participate in the exchange, lending and earning activities respectively in a decentralized manner.
Stable coins: A lot of stable coins including USDC and DAI are built based on the ERC20 standard. Such tokens are very popular in the crypto world as they help to reduce volatility by providing a pegged value.
Interoperability: Today, with the help of bridges and cross-chain solutions ERC20 tokens can be found on multiple blockchains. Wrapped tokens are ERC 20 versions of crypto assets, for instance, Bitcoin that can be used for various applications within the Ethereum ecosystem.
Guide for ERC20 Token Development: The increase in trend towards custom tokens by businesses has also resulted in the development of step by step Guide for ERC20 token development . Currently developers have access to lots of information including ready made instructions on the processes of creating ERC20 tokens. These include aspects like development of smart contracts, their testing in Ethereum test network and launching them in the main Ethereum network. Open Zeppelin, for instance, offers pre-built libraries for smart contracts to ease the creation of the tokens while adhering to the best practices of safety of the tokens.
Security and Audits: Over the years, the need for smart contract audits has become a major concern due to the increase in hacks and exploits in DeFi. ERC 20 contracts are audited by some companies that laser focus on security.
Gas Fees: Among the current issues the world is facing is the high cost of gas on the Ethereum network, especially when there is network congestion, foregoing the cheaper but quality ERC-20 transactions. Owing to this situation, Layer 2 scaling solutions such as Optimism and Arbitrum have come up that address the cost issue while keeping the standards of the ERC-20 tokens.
The Future of ERC-20 Tokens
Prospective Trends and Developments in Technology that Influence ERC-20 Tokens in Years to Come:
Ethereum 2.0 and Scalability: As Ethereum continues its upgrade to Ethereum 2.0, it will replace the current consensus mechanism of Proof of Work (PoW) with Proof of Stake (PoS). This is bound to enhance Ethereum’s scalability and lower gas charges, hence making the use of ERC-20 tokens more practical and realistic in everyday transactions.
Integration with Layer 2 Solutions: It is expected that as Layer 2 solutions such as Polygon, Optimism and zk-rollups continue to be adopted, scalability of ERC-20 tokens will be improved. These solutions offload part of the transaction verification motion away from the mainnet by dealing with some computations and only uploading the final state of events within the main blockchain.
DeFi and Beyond: As the adoption of decentralized finance grows, the use of ERC-20 tokens shall be central to this growth. However, there will most likely be increased token governance. More dominoes will fall as the DAOs that ERC20g governance will begin voting on enhancements and strategic planning of the project.
Tokenized Assets: In the wake of technologies such as ERC20 token, the real estate industry for instance, the digitization of real world objects such as real estate, artwork and other commodities will also be explored. This could add more liquidity and making markets that have come for fractional ownership betting investment possible.
Regulatory Frameworks: As the world becomes more and more focused on the regulations of cryptocurrencies exchange, the ERC-20 tokens might have to follow suit or adhere to new level standards to be accepted as a financial instrument. For example, this may mean that only certain types of token issuance may include KYC and AML measures.
Conclusion
ERC-20 tokens have transformed the concept of digital assets ever since they came into existence, and have stimulated the development of new economic models and decentralized systems. As this technology develops, so will the ERC-20 token standard. Innovations such as Ethereum 2.0 and Layer 2 scaling solutions guarantee that the ERC-20 tokens will stay at the epicenter of blockchain technology advancement providing unlimited opportunities for developers, investors and users.
The prospect of ERC-20 is optimistic as its deployment is key in ensuring the technology goes mainstream. It is hard to imagine a world of DeFi and asset tokenization devoid of an ERC-20, and for many years to come this standard will be at the center of Ethereum's flourishing ecosystem.
