Token Scan: A Modular ERC20 Token Scanner for Ethereum

The decentralized finance (DeFi) ecosystem continues to expand at a rapid pace, with thousands of ERC20 tokens now available across various decentralized exchanges (DEXs). While this growth offers exciting opportunities for developers and investors, it also introduces significant complexity in evaluating token legitimacy, identifying scams, and gathering actionable intelligence. Enter Token Scan — a lightweight, modular prototype tool designed to streamline ERC20 token analysis on the Ethereum blockchain.

Built with simplicity and extensibility in mind, Token Scan enables users to efficiently scan tokens using multiple data sources, detect potential honeypots, and retrieve quick intelligence reports — all through a clean command-line interface or direct integration as a GoLang package.

Understanding the Need for Token Intelligence

As DeFi adoption rises, so does the risk of encountering malicious tokens. Fake projects, rug pulls, and honeypots are common threats that can lead to irreversible financial losses. Traditional manual research is time-consuming and often incomplete. Automated tools like Token Scan help mitigate these risks by aggregating critical data from trusted providers into a single, accessible interface.

This prototype doesn't replace professional auditing tools but serves as an early warning system — giving developers and traders a faster way to triage tokens before deeper analysis or investment.

Core Features of Token Scan

Multi-Source Data Aggregation

Token Scan pulls insights from several reputable external APIs, including GoPlusSecurity, Honeypot.is, and QuickIntel. By combining outputs from these platforms, the tool delivers a more comprehensive view of a token’s behavior and potential risks.

For example:

GoPlusSecurity provides contract-level security checks.
Honeypot.is detects whether a token prevents selling (a hallmark of honeypot scams).
QuickIntel delivers concise overviews such as liquidity locks and ownership status.

This multi-source approach enhances reliability and reduces dependency on any single provider.

Modular Architecture for Easy Expansion

One of Token Scan’s standout features is its modular design. Each scanning method resides in its own subdirectory under /scanners, making it simple to add new modules or update existing ones without disrupting the core functionality.

This structure supports:

Rapid integration of new data sources
Independent testing of individual scanners
Custom workflows tailored to specific use cases

Developers can extend the tool by writing additional scanner packages following the established pattern.

Command-Line Interface (CLI) for Quick Access

Designed for ease of use, Token Scan includes a basic CLI that allows users to run scans directly from the terminal. This makes it ideal for scripting, automation, or quick checks during development.

Supported modes include:

multiscan: Run all available scanners
goplus: Query GoPlusSecurity API
ishoneypot: Check for honeypot traits
quickIntel: Fetch summary intelligence

Example usage:

./token-scan -mode multiscan -token 0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0

GoLang Package Integration for Developers

Beyond CLI use, Token Scan can be imported directly into Go-based applications. This allows developers to embed token scanning capabilities into dApps, trading bots, or internal security tools.

Each scanner exports a simple Scan(string) function that returns structured results or an error.

Example: Using the Multiscan Module

import "github.com/s-Amine/token-scan/scanners/multiscan"

result, err := multiscan.Scan("0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0")
if err != nil {
    fmt.Println("Error:", err)
    return
}
fmt.Println(result)

This flexibility makes Token Scan a valuable building block for secure DeFi tooling.

Installation and Setup Guide

CLI Installation (Linux)

Clone the repository:

git clone https://github.com/s-Amine/token-scan.git

Navigate into the project directory:
```
cd token-scan
```

Build and run:

go build -o token-scan main.go
./token-scan -mode multiscan -token YOUR_TOKEN_ADDRESS

Replace YOUR_TOKEN_ADDRESS with the actual ERC20 contract address.

Integrating as a GoLang Package

Install via Go modules:
```
go get github.com/s-Amine/token-scan
```

Import the desired scanner in your code:

import "github.com/s-Amine/token-scan/scanners/goplus"

Call the Scan function with a token address.

No configuration files or API keys are required — the tool uses public endpoints by default.

Frequently Asked Questions (FAQ)

Q: Is Token Scan suitable for production use?
A: Currently, Token Scan is a prototype intended for educational and experimental purposes. While functional, it should not be relied upon as the sole method for security assessment in high-stakes environments.

Q: Does Token Scan support blockchains other than Ethereum?
A: As of now, it only supports Ethereum-based ERC20 tokens. However, due to its modular design, adding support for BSC, Polygon, or other EVM chains is feasible with minor modifications.

Q: Are there rate limits when using external APIs?
A: Yes. Since Token Scan relies on third-party services like GoPlus and Honeypot.is, their respective rate limits apply. For heavy usage, consider caching results or using official API keys if supported.

Q: Can I contribute new scanning features?
A: Absolutely. The project welcomes contributions via GitHub issues and pull requests. Adding a new scanner involves creating a new package under /scanners that conforms to the existing interface pattern.

Q: How accurate are the scan results?
A: Accuracy depends on the underlying data sources. While these APIs are generally reliable, they may occasionally return outdated or incomplete information. Always verify critical findings independently.
