Cryptocurrencies have revolutionized the way we think about digital assets and transactions. Among the many innovations in the blockchain space, ERC20 tokens have emerged as a prominent standard for creating and managing tokens on the Ethereum blockchain. 

In this comprehensive guide, we will explore what ERC20 tokens are, their history, how they work, their importance and impact, advantages and disadvantages, and provide a list of top ERC20 tokens. So, let's dive in and unravel the fascinating world of ERC20 tokens.

What is ERC20?

ERC20 stands for Ethereum Request for Comment 20 and is the technical standard for creating fungible tokens on the Ethereum blockchain. 

Unlike non-fungible tokens (NFTs), which are unique and not interchangeable, ERC20 tokens are fungible, meaning they can be exchanged on a one-to-one basis with other tokens of the same type. 

These tokens represent assets, rights, ownership, access, or even cryptocurrencies that are not unique in themselves but can be transferred.

The ERC20 standard enables developers to create smart-contract-enabled tokens that can be used with various products and services. 

Since its implementation, most tokens in the Ethereum ecosystem have been created using the ERC20 standard, making it a crucial part of the Ethereum blockchain's functionality.

History of ERC20

To understand the significance of ERC20 tokens, let's look at their history. In 2015, as smart contracts gained popularity, developers realized the need for a standardized token methodology within the Ethereum ecosystem. 

Each application would require its own token without a standard, leading to interoperability issues and difficulties in exchanging tokens between different applications.

To address this problem, developer Fabian Vogelsteller proposed the ERC20 standard 2015 through the Ethereum Request for Comment (ERC) process on the project's Github page. 

The proposal, initially known as ERC-20 due to its designation as the twentieth comment, was later approved and implemented as Ethereum Improvement Proposal 20 (EIP-20) in 2017.

The approval and implementation of the ERC20 standard ensured that all smart contract tokens implemented on the Ethereum blockchain would adhere to the same set of rules, making them compatible and easily exchangeable.

How Does ERC20 Work?

To understand how ERC20 tokens work, let's delve into their underlying structure and functionality. ERC20 tokens consist of a list of functions and events that must be implemented in a token's smart contract to be considered ERC20 compliant.

ERC20 Functions

The ERC20 standard defines six mandatory functions that a token must have:

  • TotalSupply: This function returns the total number of tokens ever issued.
  • BalanceOf: The BalanceOf function allows users to check the balance of a specific token owner's account.
  • Transfer: The Transfer function automatically transfers a specified number of tokens to a designated address.
  • TransferFrom: This function allows the automatic transfer of a specified number of tokens from one address to another.
  • Approve: The Approve function grants permission to a designated address to withdraw a specific number of tokens from the token owner's account.
  • Allowance: The Allowance function returns the number of tokens approved for withdrawal by a spender from the token owner's account.

These functions provide a standard interface for ERC20 tokens, allowing them to be easily accessed, recognized, and used within the Ethereum ecosystem.

ERC20 Events

In addition to functions, ERC20 tokens also include two mandatory events:

  • Transfer: The Transfer event is triggered when a transfer of tokens is successfully executed.
  • Approval: The Approval event logs the approval of a specific address to spend a certain number of tokens.

These events help keep track of token transfers and approvals within the blockchain.

Optional ERC20 Features

Although the six functions and two events mentioned above are mandatory for ERC20 compliance, token developers can include additional features to enhance the token's usability. These optional features include:

  • Token Name: Tokens can have a name that represents their identity.
  • Token Symbol: Tokens can have a symbol as a shorthand representation of their name.
  • Decimal Points: Tokens can have decimal points to allow for fractional values.

Including these optional features provides more information and clarity about the token, making it easier for users to understand and interact.

The Importance and Impact of ERC20

The ERC20 standard has profoundly impacted the blockchain and cryptocurrency industry. Its importance lies in the fact that it introduced a standardized framework for creating tokens on the Ethereum blockchain, fostering interoperability and compatibility among different tokens and applications. Let's explore some key reasons why ERC20 is significant.

  1. Obtain Your API Endpoint and Key: Sign up for your preferred API (such as Token Metrics) and copy your endpoint URL and API key credentials.
  2. Install or Set Up Importer: For public APIs returning CSV data, use =IMPORTDATA(“URL”) directly in a cell. For JSON APIs (the vast majority), you’ll likely need to add a custom Apps Script function like IMPORTJSON or use third-party add-ons such as API Connector.
  3. Write the Script or Formula: In Apps Script, create a function that fetches and parses the JSON data, handling your API key in the request headers if needed.
  4. Display and Format: Run your script or enter your formula (e.g., =IMPORTJSON("https://api.tokenmetrics.com/v1/prices?symbol=BTC", "/price", "noHeaders")). Crypto data will update automatically based on your refresh schedule or script triggers.
  5. Automation & Limits: Be aware of Google’s rate limits and your API plan’s quota; set triggers thoughtfully to avoid errors or blocking.

Sample Apps Script for a GET request might look like:

function GETCRYPTO(url) {
  var response = UrlFetchApp.fetch(url);
  var json = response.getContentText();
  var data = JSON.parse(json);
  return data.price;
}

Change the URL as needed for your API endpoint and required parameters.

How to Connect a Crypto API to Excel

Microsoft Excel supports API integrations using built-in tools like Power Query (Get & Transform) and VBA scripting. Here is how you can set up a connection:

  1. Fetch the API Endpoint and Key: Obtain the endpoint and authorize via headers or parameters as your API documentation describes.
  2. Use Power Query: In Excel, go to Data > Get Data > From Other Sources > From Web. Enter the API URL, set HTTP method (typically GET), and configure authentication, if needed.
  3. Parse JSON/CSV: Power Query will ingest the JSON or CSV. Use its UI to navigate, transform, and load only the fields or tables you need (like price, symbol, or market cap).
  4. Refresh Data: When finished, click Load to bring dynamic crypto data into your spreadsheet. Setup refresh schedules as needed for real-time or periodic updates.
  5. Advanced Automation: For customized workflows (like triggered refreshes or response handling), leverage Excel’s scripting tools or Office Scripts in cloud-based Excel.

Note that Excel’s query limits and performance may vary depending on frequency, the amount of retrieved data, and your version (cloud vs desktop).

Best Practices and Use Cases for Crypto API Data in Spreadsheets

Why use a crypto API in your spreadsheet at all? Here are common scenarios and tips you should consider:

  • Portfolio Tracking: Dynamically update positions, track P/L, and rebalance based on real-time prices.

  • Historical Analysis: Pull historical OHLCV for custom charting and volatility tracking.
  • Custom Alerts or Dashboarding: Build automated alerts using conditional formatting or macros if price triggers or portfolio thresholds are breached.
  • Audit and Compliance: Keep timestamped logs or export data snapshots for reporting/transparency needs.

Security Tip: Always keep API keys secure and avoid sharing spreadsheet templates publicly if they contain credentials. Use environment variables or Google Apps Script’s Properties Service for added safety.

Troubleshooting, Rate Limits, and Common Pitfalls

Although spreadsheet integration is powerful, some challenges are common:

  • Rate Limits: Both Google Sheets/Excel and your crypto API will have tiered usage limits—avoid setting updates more frequently than permitted to prevent service interruptions.
  • Parsing Errors: Double-check API documentation for exact JSON/CSV field names required by your formulas or scripts.
  • Data Freshness: Sheet refreshes may lag a few minutes, so always verify the update interval matches your analysis needs.
  • Authentication Issues: If data fails to load, ensure API keys and headers are handled correctly and privileges have not recently changed.
  • Spreadsheet Bloat: Very large data pulls can slow down your spreadsheet—filter or limit queries to only what you truly need.

When in doubt, consult your API provider’s resource or developer documentation for troubleshooting tips and best practices.
