Ethereum Token Standards & How to Build Ethereum Tokens Ethereum is a decentralized blockchain platform that enables developers to build decentralized applications (dApps) and smart contracts. Ethereum tokens are digital assets that are created on the Ethereum blockchain. These tokens can represent anything from a physical asset to a virtual currency.
Ethereum tokens are created using smart contracts, which are self-executing contracts with the terms of the agreement between buyer and seller being directly written into lines of code. Ethereum tokens are based on a set of standards that define how they can be created, transferred, and managed. These standards ensure that Ethereum tokens are interoperable, meaning they can be used across different dApps and exchanges. In this article, we will explore the different Ethereum token standards and how to build Ethereum tokens.
ERC-20 Token Standard The ERC-20 token standard is the most widely used Ethereum token standard. It defines a set of rules that Ethereum tokens must follow to be considered ERC-20 compliant. These rules include functions such as transfer, balanceOf, and approve. The transfer function allows tokens to be transferred from one address to another, while the balanceOf function returns the balance of tokens held by a specific address. The approve function allows a third party to spend tokens on behalf of the token holder.
ERC-20 tokens are used for a variety of purposes, including fundraising through initial coin offerings (ICOs), creating stablecoins, and enabling access to dApps. Some popular ERC-20 tokens include Tether (USDT), Binance Coin (BNB), and Chainlink (LINK). ERC-721 Token Standard The ERC-721 token standard is used for non-fungible tokens (NFTs). Unlike ERC
-20 tokens, which are fungible (meaning they are interchangeable), NFTs are unique and cannot be exchanged for one another. ERC-721 tokens are used for a variety of purposes, including digital art, collectibles, and gaming items. ERC-721 tokens have a set of functions that define how they can be created, transferred, and managed. These functions include ownerOf, approve, and transferFrom. The ownerOf function returns the address that owns a specific NFT, while the approve function allows a third party to spend an NFT on behalf of the owner. The transferFrom function allows an NFT to be transferred from one address to another.
ERC-1155 Token Standard The ERC-1155 token standard is used for multi-token contracts. These contracts can hold multiple types of tokens, including both fungible and non-fungible tokens. ERC-1155 tokens are used for a variety of purposes, including gaming items and digital collectibles. ERC-1155 tokens have a set of functions that define how they can be created, transferred, and managed. These functions include balanceOfBatch, safeBatchTransferFrom, and setApprovalForAll. The balanceOfBatch function returns the balance of multiple types of tokens held by a specific address, while the safeBatchTransferFrom function allows multiple types of tokens to be transferred from one address to another. The setApprovalForAll function allows a third party to spend all tokens on behalf of the token holder. How to Build Ethereum Tokens To build an Ethereum token, you will need to create a smart contract that follows one of the Ethereum token standards.
You can use a programming language such as Solidity to write the smart contract. Once the smart contract is written, you will need to deploy it to the Ethereum blockchain using a tool such as Remix or Truffle. To deploy the smart contract, you will need to pay a fee in Ether (ETH), the native cryptocurrency of the Ethereum blockchain. This fee is known as gas and is used to pay for the computational resources required to execute the smart contract. Once the smart contract is deployed, you can interact with it using a tool such as MyEtherWallet or MetaMask. These tools allow you to send and receive Ethereum tokens, as well as view your token balance. Conclusion Ethereum tokens are digital assets that are created on the Ethereum blockchain.

Here’s an expanded list of Ethereum token standards, including a brief summary of each:
The ERC-223 standard aims to improve upon the ERC-20 standard by introducing a more efficient method of handling token transfers. It also seeks to eliminate the loss of tokens sent to contracts that are not designed to manage tokens.
The ERC-777 standard is an extension of the ERC-20 standard, adding new features and functionalities, such as allowing tokens to be operated by third parties on behalf of the token holder. This standard also introduces a “hook” mechanism that allows contracts to execute custom logic when receiving or sending tokens.
The ERC-884 standard is specifically designed for creating equity tokens that represent shares in a Delaware corporation. It includes features that adhere to the legal requirements for issuing equity, such as requiring the token holder’s identity and allowing for the transfer of tokens only with the issuer’s consent.
This standard is an extension of the ERC-721 token standard, enabling NFTs (non-fungible tokens) to own other NFTs or ERC-20 tokens. It allows for more complex hierarchical structures, such as a game character owning in-game assets.
The ERC-1400 standard is designed for security tokens, which represent ownership in real-world assets or investment vehicles. It includes several additional features, such as attaching metadata to transfers, providing more control for issuers and operators, and enforcing compliance with relevant securities regulations.
The ERC-1484 standard introduces the concept of digital identity, enabling on-chain identity management across multiple applications. It is designed to provide a consistent framework for identity management, allowing for the issuance, verification, and revocation of identity claims.
These are just a few of the many Ethereum token standards available. Some of these standards are still in development, while others are actively being used in various projects. The Ethereum community continues to develop new standards to address specific use cases and improve the overall functionality of tokens on the platform.
Improving the Ethereum Experience with Predictable Fees
EIP-1559, short for Ethereum Improvement Proposal 1559, is a significant upgrade to the Ethereum blockchain that was implemented in August 2021. This improvement proposal addresses various issues related to transaction fees and enhances the overall user experience on the Ethereum network.
One of the primary objectives of EIP-1559 is to enhance the predictability and efficiency of transaction fees. Prior to this upgrade, users had to manually set the gas price for their transactions, often resulting in congestion and high fees during periods of network activity. With EIP-1559, a new fee mechanism has been introduced that includes a base fee automatically determined by the network and a tip that users can add to incentivize miners. This new mechanism aims to make transaction fees more stable and reduces the need for manual fee estimation.
To further improve the Ethereum ecosystem, EIP-1559 introduces a burn mechanism for the base fee. Instead of providing the base fee to miners as a transaction fee, it is burned, permanently removing it from circulation. This deflationary mechanism helps reduce the overall supply of Ether (ETH) over time, potentially increasing its scarcity and value. This change also aligns with the long-term goal of Ethereum to transition from a proof-of-work (PoW) to a proof-of-stake (PoS) consensus mechanism, which is being implemented through Ethereum 2.0 or Eth2.
In addition to enhancing fee predictability and introducing a burn mechanism, EIP-1559 aims to make transactions more intuitive for Ethereum users. Instead of paying separate gas fees for each transaction, users can now specify the maximum fee they are willing to pay, and the network will automatically adjust the gas price based on congestion levels. This simplifies the transaction process and makes it easier for users to estimate and manage their costs.
EIP-1559 is just one part of the broader Ethereum 2.0 upgrade, which aims to make the Ethereum network more scalable, secure, and sustainable. Ethereum 2.0, or Eth2, involves a series of phased implementations, and EIP-1559 is one of the critical improvements introduced along the way. Eth2’s transition to a proof-of-stake consensus mechanism will bring benefits such as increased energy efficiency, reduced centralization risks, and improved transaction throughput.
Overall, EIP-1559 is a significant upgrade to the Ethereum network, enhancing fee predictability, user experience, and the long-term sustainability of the ecosystem. It is a step forward in making Ethereum more efficient and accessible for users and developers alike.
