Cryptocurrency Tracing: How It Works

If you’re interested in cryptocurrency tracing and how it works, read on.

Many public blockchains create a persistent transaction record that can be examined after cryptocurrency moves from one address to another. Skilled investigators can use this information, together with professional blockchain analytics and other investigative data, to follow transaction flows and develop useful leads.

Blockchain crypto tracing tools have become increasingly sophisticated, allowing investigators to analyze transaction histories that would be difficult to interpret manually.

The unauthorized transfers from FTX in 2022 remain a useful example of why blockchain tracing matters. Activity connected with the incident could be followed on public blockchains, and FTX’s bankruptcy advisors later documented preliminary on-chain tracing of unauthorized transfers. The case does not mean that tracing guarantees recovery, but it illustrates how blockchain evidence can remain visible and useful after a major theft.

What Is Cryptocurrency Tracing?

Blockchain forensics and cryptocurrency tracing are investigative methods used to analyze transactions recorded on public or pseudonymous blockchains such as Bitcoin.

Blockchain explorers and professional analytics platforms can transform large volumes of ledger data into transaction maps, attribution information, risk indicators, and other intelligence that investigators can evaluate.

Tracing may identify connections with known cryptocurrency exchanges, custodians, decentralized services, sanctioned entities, fraud-related addresses, or other relevant services where attribution information is available.

A cryptocurrency address does not, however, automatically reveal the identity of the person controlling it. Any connection between blockchain activity and a real-world person or organization should be supported by additional evidence.

Cryptocurrency tracing can assist investigations involving:

• Online fraud
• Hacking and unauthorized transfers
• Theft
• Phishing schemes
• Extortion
• Investment fraud
• Money laundering
• Litigation and financial disputes
• Insolvency and bankruptcy matters
• Compliance and regulatory investigations

The purpose of cryptocurrency tracing is not always asset recovery. Blockchain analysis may be used to understand what happened, document transaction flows, identify relevant service providers, develop investigative leads, support litigation, assist law enforcement, or evaluate financial-crime risk.

Cryptocurrency Tracing Tools

Blockchain analysis platforms help investigators examine large volumes of blockchain data and make sense of complex transaction histories.

Different platforms have different blockchain coverage, attribution datasets, visualization capabilities, and analytical features. Investigators therefore evaluate both the underlying blockchain data and the quality of the available attribution information.

Common functions include:

• Transaction monitoring and analysis. Investigators can review the history of funds, transaction flows, source and destination addresses, and interactions with known services.
• Address attribution and classification. Analytics platforms may associate addresses with known cryptocurrency exchanges, custodians, mixers, sanctions-related entities, fraud reports, darknet services, or other categories. Attribution should be evaluated as investigative information rather than automatically treated as proof of ownership.
• Visualization. Blockchain analysis platforms convert transaction activity into graphs and flowcharts that allow investigators to examine relationships between addresses and identify relevant transaction paths.

Detailed Methods and Processes in Cryptocurrency Forensics

Cryptocurrency tracing can involve several analytical methods. Each provides a different view of blockchain activity and may contribute to a broader investigation.

Attribution Data

Attribution data attempts to associate cryptocurrency addresses with known services, organizations, fraud schemes, sanctions designations, exchanges, custodians, or other entities.

For example, identifying an address associated with a centralized exchange can be important because the exchange may possess customer or transaction information that is not publicly visible on the blockchain.

Attribution does not necessarily establish which individual controlled a particular exchange account. It identifies a potentially relevant service or entity and provides an investigative lead.

Transaction Mapping

Transaction mapping converts blockchain data into visual maps and flowcharts that illustrate the movement of cryptocurrency.

These visualizations can help investigators recognize patterns associated with layering, peel chains, rapid wallet movement, exchange deposits, cross-chain activity, and other transaction behavior.

Mapping makes it possible to examine complex transaction flows that would be extremely difficult to interpret by reviewing raw blockchain records alone.

Cluster Analysis

Cluster analysis uses transaction patterns and analytical heuristics to assess whether multiple cryptocurrency addresses may be related.

For example, certain Bitcoin transaction structures can produce indicators suggesting that multiple addresses may be associated with the same wallet or entity.

Clustering can expand the scope of an investigation, but it is important to understand its limitations. A cluster should not automatically be treated as proof that every address is controlled by the same person.

CoinJoin transactions, custodial services, shared wallets, exchange infrastructure, and other circumstances can complicate clustering analysis.

Subpoena and Legal Process Targets

One important investigative objective may be identifying cryptocurrency exchanges, custodians, banks, payment providers, or other organizations that could possess relevant non-public records.

Many regulated cryptocurrency exchanges collect Know Your Customer (KYC) and Anti-Money Laundering (AML) information relating to their customers.

A private investigator cannot independently issue a subpoena, warrant, or court order. Investigators may identify potentially relevant service providers and document the transactions connected with them so attorneys, law enforcement, courts, regulators, or other authorized parties can evaluate appropriate legal processes.

Current and Historical Value

Understanding the current and historical value of cryptocurrency involved in an investigation can help establish the financial scope of a matter.

Investigators may calculate the value of transactions at the time they occurred and compare it with later values where relevant.

Value analysis can also help attorneys, law enforcement, financial institutions, insolvency professionals, or other authorized parties assess materiality and prioritize investigative activity.

Total Transactions

Transaction volume can provide insight into the potential scale of a wallet, fraud scheme, business, or other activity.

A large number of incoming transactions, for example, may indicate that an address interacted with numerous parties or potentially received funds from multiple victims.

Transaction count alone does not establish criminal activity, but it can help investigators understand the scope and characteristics of the activity being examined.

Risk Profiling

Many blockchain analytics platforms assign risk indicators based on an address’s transaction history and associations.

These systems may identify exposure to categories such as:

• Known exchanges
• Mixers
• Peer-to-peer services
• Sanctioned entities
• Ransomware
• Fraud-associated addresses
• Darknet markets
• Other high-risk services

Risk scores and labels are investigative indicators. They should be evaluated alongside the underlying transaction data and other available evidence rather than treated as definitive conclusions by themselves.

Network-Level Metadata and IP Attribution

Blockchain transactions generally do not display the originating user’s IP address or physical location.

In certain circumstances, network-level observations, service-provider logs, account-access records, device evidence, or other technical information may contribute to an investigation.

Specialized network research has also examined whether transaction propagation data can reveal information about where transactions entered a peer-to-peer network.

However, network relays, VPNs, Tor, hosted infrastructure, shared connections, and other factors make IP-based attribution difficult. An IP address should not automatically be treated as the identity or physical location of the person controlling a cryptocurrency wallet.

How Blockchain Analysis Tools for Cryptocurrency Tracing Work

As blockchain analysis tools have become more capable, people attempting to conceal cryptocurrency flows have also adopted increasingly complex techniques.

Investigators may encounter:

• Rapid movement between wallets
• Cross-chain bridges
• Token swaps
• Decentralized exchanges
• Mixers and other obfuscation techniques
• Multiple centralized exchanges
• Nested or intermediary services

This creates an ongoing challenge in which investigative techniques evolve alongside the methods used to obscure transaction trails.

Blockchain analysis platforms help investigators identify and organize relevant information recorded on public blockchains.

Investigation Process in Cryptocurrency Forensics

A cryptocurrency tracing investigation often combines blockchain analysis with traditional investigative research.

Reviewing the Narrative of Events and Timeline of the Scheme

An investigation generally begins by reviewing what happened and establishing a timeline.

This may involve collecting transaction records, communications, wallet addresses, websites, usernames, exchange records, bank information, and other available evidence.

Understanding the context surrounding the transactions helps investigators determine which blockchain activity is relevant.

Tracing Cryptocurrency Transactions

Investigators analyze cryptocurrency transactions to determine how relevant assets moved.

This may involve following transactions through multiple wallet addresses, exchanges, tokens, blockchain networks, bridges, or other services.

The objective is to document the transaction trail and identify meaningful investigative points along that path.

Forensic Analysis and Blockchain Intelligence Tools

Blockchain intelligence platforms can provide attribution information and analytical indicators relating to wallet addresses and transactions.

They can help identify interactions with known exchanges, custodians, services, fraud-associated addresses, sanctions-related entities, and other known infrastructure.

These findings can then be evaluated alongside the raw blockchain data and other investigative evidence.

Digital Forensics

Where separately authorized and within the scope of an investigation, digital forensics may provide additional evidence from electronic devices, files, emails, or other digital sources.

Digital forensic work is distinct from blockchain tracing, but information from both disciplines can sometimes be used together in a broader investigation.

Legal Discovery Through Subpoenas, Warrants, or Other Authorized Processes

Blockchain analysis may identify organizations that potentially possess relevant private records.

For example, a centralized cryptocurrency exchange may hold KYC information, transaction records, or account-access information.

Private investigators do not issue subpoenas or warrants themselves. Attorneys, courts, law-enforcement agencies, regulators, and other authorized parties may use appropriate processes to seek records depending on the jurisdiction and circumstances.

The investigator’s role may include documenting why a particular exchange or other service is relevant and identifying the transactions involved.

The Application of Cryptocurrency Forensics

Cryptocurrency forensics and asset tracing have applications beyond scam investigations.

• Civil Litigation: Analyzing cryptocurrency transactions and developing evidence relevant to financial disputes.
• Criminal Investigations: Providing technical blockchain evidence that may assist law enforcement and prosecutors.
• Bankruptcy and Insolvency Proceedings: Identifying and tracing digital assets relevant to an estate or financial proceeding.
• Regulatory Enforcement: Supporting analysis of potentially illicit or non-compliant cryptocurrency activity.
• Judgment Enforcement and Asset Tracing: Identifying cryptocurrency activity that may be relevant to authorized enforcement proceedings.
• AML and Compliance Investigations: Examining transaction exposure and relationships with higher-risk services or addresses.

Attribution Data

Collecting and evaluating attribution data can help investigators associate cryptocurrency transactions with known entities or services.

Attribution is not always likely to produce a direct connection between an individual and a blockchain transaction.

It may, however, link transactions with:

• Cryptocurrency exchanges
• Custodians
• Fraud schemes
• Known services
• Sanctions-related entities
• Darknet services
• Other identified infrastructure

Attribution may also identify fiat off-ramps or exchanges through which cryptocurrency was transferred.

Investigators can additionally compare addresses with fraud reports, sanctions data, lawfully available databases, and other intelligence sources.

Web Scraping and Open-Source Research

Automated collection and analysis of publicly available online information can assist some investigations when conducted lawfully and appropriately.

Relevant information may be found on:

• Websites
• Social-media platforms
• Forums
• Public databases
• Online advertisements
• Corporate records
• Other publicly accessible sources

Cryptocurrency investigators may use OSINT tools and other research methods to find information that provides context for blockchain activity.

Transaction Mapping

Transaction mapping is one of the most visually useful elements of blockchain investigations.

Flowcharts and graphs illustrate relationships between addresses, transactions, and attributed services.

Visual examination may reveal:

• Layering
• Peel chains
• Exchange deposits
• Cross-chain movement
• Consolidation of funds
• Distribution across multiple addresses
• Other transaction patterns

Blockchain analytics dramatically reduce the amount of manual work required to analyze complex transaction histories.

Scam Database Monitoring and Research

Fraud reports and scam databases can provide additional context for cryptocurrency addresses, websites, usernames, or other indicators.

Investigators may compare suspicious blockchain activity with information reported through reputable public or proprietary sources.

A database match should still be verified and evaluated in context. A report or label is an investigative lead rather than automatic proof that a particular person committed a crime.

Identifying Address Clusters

Cryptocurrency users can generate large numbers of addresses, and sophisticated actors may use many addresses in an attempt to make transaction flows more difficult to follow.

Blockchain patterns can sometimes provide clustering indicators suggesting that addresses may be related.

Investigators can use these indicators to expand the scope of an analysis and identify additional transactions worth reviewing.

Clustering should be interpreted carefully. It is an analytical technique, not automatic proof that every address in a cluster belongs to one individual.

Common Spend and Address Reuse

Bitcoin investigators may use transaction heuristics when examining relationships between addresses.

One example is the common-input heuristic, where multiple addresses are used as inputs to the same transaction.

In some circumstances, this may suggest common control. However, CoinJoin transactions, custodial wallets, payment services, and other transaction structures can create exceptions.

For that reason, investigators should not automatically conclude that every address appearing together in a transaction belongs to the same entity.

Address reuse can also reduce privacy because repeated use creates additional publicly visible transaction history associated with the same address.

Establishing Targets for Legal Process

The cryptocurrency ecosystem includes exchanges, custodians, payment providers, financial institutions, and other services that may possess information relevant to an investigation.

Many regulated providers collect customer-identification information and maintain transaction records.

If cryptocurrency reaches one of these services, investigators may document:

• The relevant wallet address
• The transaction hash
• The date and amount
• The blockchain network
• The attributed service provider
• The surrounding transaction path

This information can help attorneys, law enforcement, courts, regulators, or other authorized parties evaluate whether records should be requested through an appropriate process.

Private cryptocurrency investigators do not independently compel exchanges to disclose customer records or freeze accounts.

Network-Level Metadata

A Bitcoin address does not ordinarily reveal an IP address.

Network-level research has examined transaction propagation and other peer-to-peer network metadata, but drawing reliable conclusions about the origin of a transaction can be difficult.

Investigators may also encounter IP information through authorized service-provider records, server logs, device evidence, or other sources outside the blockchain itself.

VPNs, Tor, proxies, shared networks, hosted systems, and relays can significantly limit the value of IP geolocation as evidence of a person’s identity or physical location.

Reading Into Total Transactions

Transaction volume can help investigators evaluate the scale and characteristics of blockchain activity.

An address receiving payments from many unrelated sources, for example, may warrant further analysis to determine whether the activity is consistent with a broader scheme.

Large or multi-victim matters may also attract greater attention from law enforcement or regulatory authorities, although the decision to investigate rests with those authorities.

Automated Risk Profiling

Manually reviewing millions of cryptocurrency addresses is not practical.

Professional blockchain analytics platforms can use attribution datasets and transaction analysis to assign risk indicators to addresses or transactions.

Investigators can then review the underlying evidence associated with those indicators.

Automated risk scoring assists analysis, but professional judgment remains important. A risk score alone should not be treated as proof of criminal activity.

Identifying High-Value Addresses

Understanding the value associated with particular wallet addresses can help investigators determine the financial significance of different parts of a transaction trail.

This may assist with:

• Prioritizing investigative resources
• Documenting the scale of a matter
• Calculating historical transaction values
• Identifying potentially material wallets or services
• Providing useful information to authorized legal or law-enforcement parties

Whether assets can be restricted, frozen, seized, or otherwise subject to legal process is a separate question that depends on the circumstances, jurisdiction, custodian, and available authority.

Choosing Capable Crypto Tracing Specialists

Many companies now advertise cryptocurrency tracing or investigation services. Understanding what separates a legitimate investigative provider from unrealistic recovery claims is important.

• Professional tracing specialists use appropriate analytical tools. Platforms such as Chainalysis Reactor, Qlue, and other blockchain intelligence systems provide different datasets and analytical capabilities. Multiple tools may sometimes help corroborate findings or provide additional blockchain coverage.
• Serious investigators provide clear deliverables. A professional engagement should explain what will be investigated and what report, analysis, or other work product the client will receive.
• Investigators should understand cross-border cases. Cryptocurrency activity can involve wallets, exchanges, websites, banks, and individuals in multiple jurisdictions.
• Experienced investigators understand the distinction between tracing and legal authority. They should not claim that they can independently subpoena an exchange, freeze cryptocurrency, seize assets, or guarantee recovery.
• Professional investigators protect client information. Confidential financial and investigative information should be handled through appropriate security and privacy procedures.

Support for Legal Counsel

CNC Intelligence provides cryptocurrency tracing and investigative support to attorneys involved in litigation, fraud matters, asset tracing, insolvency proceedings, and other cases involving digital assets.

Identifying Potential Sources of Records

Blockchain analysis can identify exchanges, custodians, payment providers, or other organizations that may possess information relevant to a matter.

CNC Intelligence can document the transactions and attribution supporting those investigative leads so counsel can evaluate whether discovery, subpoenas, preservation requests, or other legal procedures may be appropriate.

Organizing Evidence in Multi-Victim Matters

In cases involving multiple victims or transactions, investigators may help organize blockchain evidence, identify common wallet addresses or services, and document recurring transaction patterns.

Where appropriate and within the authorized scope of an investigation, additional investigative research or witness outreach may also support counsel’s work.

Due Diligence on Identified Principals

Due diligence and background investigations may provide additional information relating to individuals or entities identified during an investigation.

Depending on the circumstances and applicable law, research may examine:

• Corporate affiliations
• Professional history
• Litigation records
• Public regulatory information
• Sanctions or watchlist information
• Other lawfully available records

These findings can help legal teams evaluate investigative leads developed through cryptocurrency tracing.

Coordination With Law Enforcement

Cryptocurrency tracing can also support reports or referrals to law-enforcement agencies.

CNC Intelligence may assist clients and counsel by organizing relevant transaction information, preparing investigative reports, explaining blockchain findings, and responding to technical questions concerning the investigation.

Law-enforcement agencies independently determine whether to open or pursue an investigation and possess legal authorities that private investigators do not.

CNC Intelligence does not issue subpoenas, obtain warrants, seize cryptocurrency, or compel exchanges to take action.

Cryptocurrency Tracing: Bottom Line

Cryptocurrency tracing has developed into a sophisticated investigative discipline. Public blockchain data can allow investigators to follow transaction paths, analyze wallet relationships, identify known exchanges and services, evaluate attribution information, and develop investigative leads.

Cases such as the 2022 FTX unauthorized transfers illustrate the enduring value of on-chain evidence: cryptocurrency may move rapidly, but transactions recorded on public blockchains can remain available for later analysis.

At the same time, blockchain tracing has important limitations. A wallet address does not automatically reveal a person’s identity, clustering is not proof of common ownership, and a private investigator cannot independently subpoena an exchange, freeze an account, seize cryptocurrency, or reverse a blockchain transaction.

CNC Intelligence provides cryptocurrency tracing, blockchain analysis, asset tracing, cyber intelligence, and investigative reporting for individuals, law firms, law enforcement, corporations, financial institutions, and other authorized clients.

CNC Intelligence does not independently freeze, seize, hold, release, or return cryptocurrency or other assets and cannot guarantee recovery.
