Background

Cryptocurrencies such as Bitcoin, Ethereum, and USDT have become integral to modern digital economies. However, they are also frequently misused for illegal activities including money laundering, ransomware payments, terror financing, online frauds, and dark web transactions. Law enforcement agencies face significant challenges in tracing the flow of funds due to the pseudo-anonymous nature of blockchain transactions and the use of privacy coins and mixers.

Problem Statement

Investigators require a smart, easy-to-use forensic tool to trace cryptocurrency transactions, detect suspicious wallet activities, identify links between wallets and real-world identities, and present the data in a form suitable for judicial proceedings.

Key Objectives

Build a Cryptocurrency Investigation Tool that can:

1. Ingest wallet addresses, transaction hashes, or blockchain data (via APIs or manual

input).

2. Trace the flow of cryptocurrency across multiple addresses (forward and backward

tracing).

3. Identify patterns such as:

- High-frequency micro-transactions

- Mixer/tumbler service usage

- Wallet clustering and address re-use

- Interaction with known high-risk or blacklisted wallets

4. Visualize transaction graphs and fund flow in an interactive dashboard.

5. Enable tagging of wallets with user-generated metadata (e.g., suspect, exchange,

mixer).

6. Generate case summary reports and visual charts exportable in PDF/Word.

Functional Requirements

- A functional prototype demonstrating transaction tracing and wallet analytics.

- A dashboard with visualizations of fund flow and network maps.

- A report generator summarizing investigative findings.

- Documentation explaining logic used for clustering, tagging, and pattern detection.

- Optional: Integration of threat intel feeds or blockchain intelligence APIs.

Evaluation Criteria

- Accuracy of transaction tracing

- Usability for investigators and law enforcement personnel

- Clarity and depth of visual analytics

- Innovation in tracing and tagging techniques

- Potential for real-world deployment

Deliverables

The tool can revolutionize cryptocurrency-related investigations by empowering cybercrime units, financial intelligence wings, and forensic auditors with actionable insights. It will improve the traceability of illicit transactions and contribute to the fight against financial cybercrime.
