Core Methodologies
Chainalysis specializes in tracking and interpreting cryptocurrency transactions through advanced blockchain analysis techniques. A fundamental practice is transaction tracing, which involves following the flow of funds from one address to another across the blockchain ledger to map out the path of transactions. In tandem, Chainalysis employs address clustering algorithms – grouping addresses that likely belong to the same entity using various heuristics. One widely used heuristic is co-spend clustering (common-input analysis), where if multiple addresses are used as inputs in a single transaction, they are assumed to be controlled by the same owner. This method even extends across blockchain forks; for example, an address present on Bitcoin before the Bitcoin Cash split can be recognized on both chains as one entity. Chainalysis also uses behavioral heuristics that detect patterns in how transactions are structured or timed (such as how wallets handle fees or generate change outputs) to identify particular wallet software or services. These patterns help attribute clusters of addresses to known entities like exchanges or mixers. Importantly, Chainalysis supplements algorithmic clustering with intelligence-based techniques – a dedicated intelligence team integrates off-chain information (e.g., data leaks, darknet forums, court documents) to tie addresses to real-world entities and improve attribution accuracy. The platform is designed to be conservative and deterministic in its analysis; each heuristic’s results are reproducible using on-chain data, and Chainalysis claims that repeated runs yield identical outcomes that can be verified independently on the blockchain. Notably, the system is built to recognize and handle obfuscation tactics: for instance, if a CoinJoin mixing transaction is detected, Chainalysis will intentionally avoid merging those addresses in a cluster to prevent erroneous attributions. By combining these methodologies – transaction path tracing, multi-layered clustering (network-wide and service-specific heuristics), and external data intelligence – Chainalysis can trace crypto funds and map a “graph” of interactions that reveal the entities behind pseudonymous addresses. This multi-pronged approach allows investigators to uncover hidden connections in blockchain data while aiming to minimize false linkages.
Key Technologies and Tools
Chainalysis offers several software tools and services that operationalize its blockchain analysis for different needs:
Chainalysis Reactor – Reactor is a powerful investigation platform designed for tracing cryptocurrency transactions and visualizing relationships on the blockchain. It provides an intuitive interface where investigators, such as law enforcement or compliance analysts, can input an address or transaction and visualize its connections to other addresses or entities on a graph. The platform automatically identifies patterns associated with illicit activities, such as clusters linked to darknet markets or ransomware wallets, and allows users to track the movement of funds through multiple hops.
Reactor helps build cases by linking suspicious crypto addresses to real-world organizations through Chainalysis’s attribution data. It also supports generating reports and evidence for investigations. Key advanced features include automated pathfinding algorithms to trace transaction paths, the ability to set “watch” alerts on addresses for future activity, and collaboration tools to share investigation graphs.
In essence, Reactor serves as a primary tool for forensic crypto analysis, widely regarded as “the tool of choice” for blockchain investigators and regulators.
Chainalysis KYT (Know Your Transaction) – KYT (Know Your Transaction) is a real-time transaction monitoring solution designed for compliance teams in cryptocurrency businesses and financial institutions. It continuously scans incoming and outgoing crypto transactions against Chainalysis's risk models to flag high-risk activity in accordance with Anti-Money Laundering (AML) regulations.
KYT automatically generates a risk score or alert when funds are linked to illicit entities, such as if a deposit originates from a hacked fund or a sanctioned address. Compliance officers can configure KYT with custom risk thresholds and receive live alerts to investigate or freeze transactions that violate those thresholds.
This tool assists exchanges and banks in meeting regulatory requirements by identifying suspicious behaviors like structuring, usage of mixing services, or involvement with darknet markets. It also generates reports for regulators, functioning as a crypto AML surveillance system that screens millions of transactions to detect money laundering patterns and ensure that businesses avoid transacting with blacklisted wallets.
Chainalysis Market Intel – Market Intel is a market intelligence and analytics platform that utilizes Chainalysis's extensive blockchain dataset to provide insights into cryptocurrency adoption and usage trends. It offers real-time data and metrics on how cryptocurrencies are being used and held across the market, assisting investors, financial analysts, and regulators in making data-driven decisions.
Built on a proprietary dataset that links addresses to known entities (accumulated since 2014), Market Intel presents macro-level indicators such as total flows into exchanges, volume transacted by illicit actors, regional adoption indexes, and other economic trends within the crypto ecosystem. Each data point is backed by Chainalysis’s on-chain attribution, with auditable proof for each labeled entity, ensuring the accuracy of the metrics.
Market Intel is commonly used for research reports and investment analysis, such as tracking the growth of decentralized finance (DeFi) activity, identifying fund movements by long-term holders, or assessing the impact of regulatory news on crypto transaction volumes. By distilling blockchain data into accessible charts and reports, Market Intel helps stakeholders understand the broader crypto-economic landscape beyond just compliance or investigations.
(Chainalysis also provides other specialized products, such as Chainalysis Kryptos for due diligence on cryptocurrency businesses and Chainalysis Storyline for investigating DeFi and NFT transactions, which complement the core tools above. However, Reactor, KYT, and Market Intel remain the flagship offerings addressing investigation, compliance, and market analysis needs, respectively.)
Data Collection and Analysis
To power its analytics, Chainalysis maintains a robust data collection pipeline that ingests and enriches blockchain data from a wide array of sources. The company runs nodes or interfaces with nearly all major blockchain networks, examining every block from a blockchain’s inception (genesis block) through the present, building a comprehensive historical record of transactions.
This approach has enabled Chainalysis to compile the world’s largest database, mapping cryptocurrency addresses and transactions to real-world entities—a dataset that has been expanding since 2014. By 2022, this database covered trillions of dollars in transaction value and tens of thousands of identified services. One report highlighted over $13.6 trillion in tracked value, with more than 30,000 “named” entities, such as exchanges, darknet markets, and scams, profiled in the system.
Blockchain data ingestion involves parsing every transaction on supported chains (such as Bitcoin, Ethereum, and hundreds of others), normalizing the data, and applying Chainalysis’s clustering algorithms to organize addresses into entities. The analysis uses deterministic heuristics to group addresses, augmented by machine learning models that can detect anomalous patterns or predict which cluster an unknown address most likely belongs to.
In addition to on-chain data, Chainalysis continuously enriches its dataset with attribution information from off-chain sources. For example, some cryptocurrency businesses (exchanges and wallet providers) that are Chainalysis clients voluntarily share their address labels and transaction data. This provides ground-truth insights—if an exchange provides a list of deposit addresses, Chainalysis can confirm and expand the cluster of addresses associated with that exchange. The company’s intelligence team also gathers information from open-source sources, including monitoring darknet sites, forums, social media, and even leaked databases to identify mentions of cryptocurrency addresses.
If a darknet market lists a payout address or a hacker posts their Bitcoin address on a forum, Chainalysis adds that link to its repository. Court documents and law enforcement reports are also valuable for attribution, such as when an indictment reveals certain addresses belong to a crime ring. Through data partnerships and manual investigative work, Chainalysis continuously expands its knowledge base of which addresses belong to which entity.
Once collected, the data undergoes rigorous validation and quality control. Chainalysis emphasizes accuracy, highlighting that inaccurate data is worse than missing data. The firm has a multi-layered validation process that includes ground-truth manual reviews to minimize false positives. In practice, this means any algorithmic cluster or label might be cross-checked by analysts or corroborated with information from customers. Many cryptocurrency services whose addresses are clustered in the Chainalysis database are also clients using Chainalysis’s monitoring tools. These clients regularly provide feedback or lists of their own addresses, creating a feedback loop. Thousands of addresses are shared by customers daily, and Chainalysis uses these to verify that its clustering is correct.
According to the company, no discrepancy has ever been found between a customer-provided address list and Chainalysis’s attribution, suggesting a high degree of accuracy in their clustering. All entity labels in the database are auditable, meaning there is evidence (on-chain or via sources) supporting why a particular address is attributed to a certain entity. Chainalysis’s architecture is built to scale with growing data, allowing it to scan billions of transactions rapidly in search of patterns. This enables the firm to incorporate new blockchain networks and their entire histories in a relatively short time. It also supports every token on smart contract platforms (like all ERC-20 tokens on Ethereum) through generalized frameworks that ingest token transfer events. This breadth of coverage ensures that analytics aren’t limited to base cryptocurrencies but also extend to DeFi tokens and NFTs.
Finally, Chainalysis transforms raw data into actionable analytical outputs. These include risk scores (for KYT’s real-time screening of transactions), clustering tags (used in Reactor to label addresses with owner entity or category), and aggregated metrics (for Market Intel charts). Proprietary models assess factors like an address’s indirect exposure to known illicit entities (e.g., if it received funds that passed through a mixer) to assign a risk level. Continuous monitoring systems are in place to detect new illicit patterns. For example, if a new scam address is identified, the system can retroactively mark funds that interacted with it as higher risk.
By combining big-data infrastructure with human intelligence, Chainalysis is able to process the ever-expanding blockchain universe into a refined dataset that is usable for investigations, compliance, and research. As of late 2023, the platform had indexed over 1 billion unique cryptocurrency addresses and attributed them to about 80,000+ real-world entities or services, reflecting the massive scope of its data analysis operation.
Forensic and Compliance Techniques
Forensic Investigations (Law Enforcement Support): Chainalysis’s services have become crucial in criminal investigations involving cryptocurrency. Using tools like Reactor and the Chainalysis Investigations software suite, law enforcement agencies can "follow the money" through complex webs of transactions to uncover illicit activity. Chainalysis provides both software and expert support to these agencies, helping trace funds linked to crimes such as drug trafficking, ransomware attacks, darknet market commerce, terrorism financing, and fraud.
The investigative technique often involves identifying a suspicious cryptocurrency address (e.g., a ransom payment wallet or a darknet vendor’s payout address) and using Chainalysis to map all the hops that funds take from or to that address. Since Chainalysis has clustered many addresses by owner, investigators can frequently discover that those funds eventually flow into a known exchange or service. At that point, law enforcement can issue subpoenas or legal requests to those exchanges to obtain the KYC (Know-Your-Customer) information of the account holder, thus unmasking the perpetrator. This workflow has led to numerous high-profile case breakthroughs.
Chainalysis is credited with assisting in the investigation and/or asset recovery in cases like the Silk Road dark web marketplace takedown, where in 2020, the U.S. government seized over $1 billion in Bitcoin from a Silk Road hacker. Other notable cases include the 2019 Welcome to Video child exploitation site shutdown, attribution of major exchange hacks to North Korea’s Lazarus Group (such as the $250M Upbit hack), and the recovery of the Bitcoin ransom from the Colonial Pipeline ransomware attack in 2021. In these scenarios, Chainalysis’s tracing illuminated how funds moved across wallets, ultimately enabling authorities to seize or freeze assets and arrest suspects.
Chainalysis often works closely with investigators, providing training and on-site expertise. In 2022, the company launched a dedicated Government Solutions subsidiary with a team of about 90 experts to serve U.S. defense, intelligence, and law enforcement agencies with tailored investigative support. This includes “all-source case support,” meaning Chainalysis can integrate blockchain analysis with other intelligence (financial records, open source intel, etc.) to build a comprehensive picture for a case.
By augmenting traditional investigative techniques with blockchain forensics, Chainalysis helps law enforcement follow digital money trails that would otherwise be opaque, enabling them to disrupt criminal operations relying on cryptocurrencies. Federal agencies in the U.S. have made Chainalysis a go-to tool—over ten different agencies (including the FBI, IRS, DEA, Homeland Security, and others) collectively spent more than $10 million on Chainalysis’s software and training from 2015 to 2020 alone. This investment has paid off in numerous multi-agency efforts to tackle crimes ranging from darknet narcotics sales to sanctions evasion. Aside from tracing and attribution, Chainalysis also assists in cryptocurrency seizure and recovery; when authorities confiscate crypto wallets, Chainalysis helps secure the funds and provides auditing to ensure all assets are accounted for before liquidation.
Regulatory Compliance and Monitoring: Financial institutions, crypto exchanges, and fintech companies leverage Chainalysis to ensure compliance with Anti-Money Laundering (AML) and Countering Financing of Terrorism (CFT) regulations and safeguard their platforms from illicit money flows. A key technique for this is continuous transaction monitoring through Chainalysis KYT (Know Your Transaction). Every transaction a business processes—whether a deposit, withdrawal, or transfer—can be automatically screened against risk indicators. For example, if a user at an exchange receives cryptocurrency that can be traced back to a known darknet market or a flagged scam, KYT will immediately flag that transaction as high risk. The compliance team can then investigate further, pausing the transaction, requesting additional information from the customer, or filing a Suspicious Activity Report if required.
Chainalysis’s data provides context for why a transaction is risky, showing the path of funds. For instance, KYT might indicate, “This deposit originated from Wallet X, associated with ransomware strain Y,” or “Funds came via a mixer from an address linked to illicit activity.” This allows institutions to freeze illicit funds—alerting law enforcement or victims when stolen funds are attempted to be cashed out. KYT has the capability to proactively flag hacker wallets; if hackers send funds to an exchange using KYT, the system can detect connections to known hack addresses and alert the exchange to block or lock the funds.
Compliance officers using KYT can configure rules aligned with regulations, such as OFAC sanctions lists (which will flag any interaction with sanctioned crypto addresses), thresholds for large transactions, or patterns indicative of structuring. The tool supports real-time notifications, enabling banks or financial institutions to take immediate action, for example, if a customer receives crypto from a sanctioned entity.
Beyond transaction monitoring, Chainalysis provides address screening services for compliance. Companies can check whether a specific crypto address is associated with crime or sanctions before doing business with it. Many exchanges use this to vet withdrawal addresses or screen new user deposit addresses. Chainalysis’s data also aids firms in conducting enhanced due diligence on customers and counterparties. For instance, through Chainalysis Kryptos or reports, a firm can assess how much exposure to illicit activity a customer’s wallet has had over time or whether a business partner’s crypto transactions show any red flags (like ties to fraud). In the brokerage and banking sectors, such tools are increasingly used to decide whether to allow crypto-related transactions or accounts.
Regulators and audit firms partner with Chainalysis to perform market surveillance and compliance analytics. By analyzing industry-wide data through Market Intel and custom studies, they can identify trends such as spikes in darknet market revenue or regional surges in suspicious activity, which inform policy and enforcement priorities. Chainalysis also publishes compliance and crime reports (such as the annual Crypto Crime Report), which have become reference materials for regulators. These reports quantify metrics like the total criminal share of crypto transactions, money laundering routes, and emerging risks, guiding compliance programs.
In summary, Chainalysis’s compliance techniques involve using its extensive data to identify illicit activity in real-time, helping crypto businesses meet legal obligations while protecting their reputation and preventing losses. This ensures a safer crypto ecosystem where legitimate users can transact with less risk of fraud, and illicit actors face greater difficulty in moving funds without detection.
Use Cases and Clients
Chainalysis’s technology is used across a variety of industries and sectors. Below are the key groups of clients and how they utilize Chainalysis services:
Government Agencies & Law Enforcement: National and international agencies rely on Chainalysis to investigate cryptocurrency-related crimes and enforce financial laws. In the United States, around a dozen federal agencies, including the IRS, FBI, DEA, HSI, and others, have contracted Chainalysis for blockchain tracing tools and training, spending over $10 million from 2015 to 2020 on these services. Agencies use Chainalysis to track illicit flows, such as tracing ransomware payments or following funds in fraud cases, and to identify suspects by linking crypto addresses to exchanges or services that can be subpoenaed.
Intelligence and defense organizations also utilize blockchain analytics to monitor threats like sanctions evasion and terrorist financing. Beyond U.S. agencies, Chainalysis supports international law enforcement (Europol, INTERPOL, and various national police forces) and regulators. For example, European authorities have worked with Chainalysis to crack down on darknet markets, and regulators in Asia-Pacific regions use Chainalysis data to inform policy on crypto asset risks.
The establishment of the Chainalysis Government Solutions subsidiary in 2022 highlights the growing demand from the public sector. This subsidiary provides a dedicated team to serve government clients with investigative services and custom analytics. Overall, government use cases for Chainalysis focus on crime detection, asset seizure, intelligence analysis, and compliance enforcement in the cryptocurrency space.
Cryptocurrency Exchanges & Trading Platforms: Crypto businesses are a significant client base for Chainalysis, using the platform primarily for compliance and security. Leading exchanges like Coinbase and Binance rely on Chainalysis software to monitor crypto transactions and comply with Anti-Money Laundering (AML) regulations. These platforms integrate Chainalysis KYT to continuously screen deposits and withdrawals, helping them spot illicit funds—such as proceeds from hacks or scams—and block suspicious activity before it escalates. By doing so, exchanges not only protect their users but also strengthen their relationships with regulators.
Exchanges also use Chainalysis tools to investigate internal incidents. For example, if an exchange wallet is hacked, Chainalysis Reactor can trace where the stolen funds are sent. Beyond large global exchanges, a wide range of crypto businesses use Chainalysis. DeFi platforms and protocols use the data to flag hacked funds moving through their smart contracts, while brokerage apps, payment processors, and ATM networks use Chainalysis to vet transactions. Emerging crypto startups also rely on Chainalysis’s Business Data and Kryptos products to conduct due diligence on partners and high-value customers, ensuring they haven't been involved in illicit blockchain activities.
In essence, any business dealing with cryptocurrency transactions can be a client of Chainalysis. The platform advertises clients from over 70 countries, including dozens of exchanges and fintech firms. The goal for these clients is to prevent money laundering, comply with international guidelines (such as the FATF Travel Rule), and maintain a clean ecosystem for users.
Financial Institutions (Banks & Insurance): Traditional financial institutions have increasingly turned to Chainalysis as they engage with the crypto market. Major banks and investment firms—such as BNY Mellon and Barclays—have been reported as Chainalysis customers or investors, using its data for risk management in their digital asset divisions. Banks that facilitate cryptocurrency services, such as allowing customers to buy Bitcoin or banking crypto exchanges, use Chainalysis to conduct risk assessments of crypto transactions and clients. For example, if a bank’s client is a crypto exchange, the bank may use Chainalysis to periodically audit the exchange’s on-chain activity to ensure no blacklisted funds are flowing through accounts.
Insurance companies also use Chainalysis, particularly those offering crypto-related insurance, like crime insurance for exchanges or custodians. They analyze blockchain data to assess the risk of hacks or fraud before underwriting a policy, and in the event of a claim (such as an exchange hack), they rely on Chainalysis to trace stolen assets and validate losses.
Cybersecurity firms and forensic consultants partner with Chainalysis as well. For instance, a cybersecurity firm investigating a breach involving crypto theft would use Chainalysis to track the stolen funds. Additionally, consulting firms like Deloitte and KPMG have partnered with Chainalysis to incorporate its blockchain analytics into their fraud and financial crime consulting for banks.
This growing trend indicates that mainstream finance views Chainalysis as the go-to provider for crypto transaction transparency, helping with everything from anti-fraud efforts to regulatory compliance checks. As cryptocurrencies become more integrated with traditional finance, banks and institutions rely on Chainalysis to bridge the knowledge gap and ensure that crypto transactions meet the same compliance standards as fiat transactions.
Other Sectors and Use Cases: Chainalysis’s client base also includes government regulators, auditors, and intelligence agencies that use the data for oversight and research rather than criminal investigations. Financial regulators, for example, may use Chainalysis Market Intel and reports to track the overall level of illicit activity in crypto markets year over year or to assess whether new regulations are needed for areas like DeFi. Tax authorities, including agencies like the U.S. IRS and their counterparts abroad, use Chainalysis to uncover tax evasion via crypto, identifying individuals who haven't reported cryptocurrency gains by analyzing blockchain records.
In the private sector, legal and accounting firms may subscribe to Chainalysis tools to assist in bankruptcy cases involving crypto assets, tracing and recovering assets for creditors, or to perform forensic analysis in litigation. Even consumer-facing companies, such as e-commerce or tech firms accepting crypto payments, may use Chainalysis to screen payments for compliance.
Notably, cybercrime threat intelligence teams use Chainalysis to investigate hacker networks. For instance, tracing how ransomware groups cash out their crypto can help identify their infrastructure. Chainalysis’s data is also used in academia and research to study crime patterns and the economic impact of cryptocurrencies. Though not always direct commercial clients, Chainalysis often collaborates with researchers and provides datasets for study.
Overall, Chainalysis’s client profile is broad, spanning government agencies, crypto-native companies, and Fortune 500 enterprises. All leverage blockchain analytics to gain transparency into the otherwise pseudonymous cryptocurrency financial system.
Limitations and Challenges
Despite its leading position, Chainalysis faces several technical and methodological limitations, as well as criticisms regarding its accuracy and approach. One inherent challenge is dealing with the increasing use of privacy measures in cryptocurrency. While Bitcoin and many blockchains are transparent, privacy-centric coins like Monero or Zcash, as well as techniques like mixers and coin tumbling services, significantly complicate analysis. Chainalysis has acknowledged difficulty in tracing coins with strong privacy features, and even advanced AI models struggle with these coins, which remain a challenge for blockchain analytics firms.
For example, Monero transactions obscure the sender, receiver, and amount, making Chainalysis’s usual clustering and tracing techniques largely ineffective. In such cases, Chainalysis often resorts to heuristic or statistical guesses or relies on external clues, and in some instances, it cannot provide attribution at all. Similarly, mixing protocols like CoinJoin or newer smart contract mixers can break the assumptions behind co-spend heuristics by pooling funds from many users and redistributing them. Although Chainalysis detects and flags mixing activity, those funds essentially disappear from deterministic tracing until they surface at a known entity.
This cat-and-mouse dynamic means savvy criminals can employ countermeasures to evade Chainalysis’s tracking, and the company must constantly update its techniques to stay ahead.
Another set of challenges comes from accuracy and the potential for false positives or errors in Chainalysis’s clustering algorithms. While Chainalysis prides itself on data accuracy, critics have pointed out that its attribution heuristics are not peer-reviewed and can sometimes lead to incorrect conclusions. A notable controversy emerged in the case of U.S. v. Sterlingov (2021), where Chainalysis’s evidence linking the defendant to a Bitcoin mixing service was scrutinized by outside experts. In court, a Chainalysis representative conceded a lack of scientific, published evidence for the accuracy of their Reactor software’s results, leading the defense to liken Chainalysis to “the Theranos of blockchain forensics.”
An expert report by a competing blockchain analytics firm (CipherTrace) in that case highlighted serious accuracy issues in Chainalysis’s behavioral clustering heuristic—a technique used to group addresses based on transaction patterns and alleged wallet fingerprinting. CipherTrace found this heuristic to be “overly inclusive,” with roughly a 64% error rate in the context examined. In other words, it may have lumped together addresses that were not truly related, casting doubt on the conclusions. Such errors can be compounded: if an initial cluster is wrong, subsequent tracing of that cluster’s activity spreads the error further. The report noted that successive runs of co-spend and behavioral clustering on the same data could amplify false linkages, potentially ensnaring completely unrelated addresses into one cluster.
Chainalysis’s practice of single entity clustering—attributing a group of addresses to one purported owner without full confirmation—was also criticized as non-verifiable and prone to mistakes. Law enforcement agents have privately expressed frustration when using Chainalysis in some cases, finding that they encountered errors or false leads that wasted investigative effort. These concerns show that Chainalysis’s output is only as good as the heuristics and data feeding it. If those are flawed, the conclusions may be wrong.
A broader criticism is the “black box” nature of Chainalysis’s technology. The company does not publicly disclose detailed methodologies for all its heuristics, understandably due to proprietary and security reasons. However, this opacity means its results can be hard to independently verify or challenge. In the Sterlingov case, experts argued that Chainalysis’s methods hadn’t been audited or validated by third parties. The defense expert recommended that Chainalysis attribution data should not be used as sole evidence in court because the models are unverified and the data collection trail isn’t transparent. The call was for audited, well-documented processes rather than secret algorithms using potentially unverified user data.
This black-box critique draws a parallel with concerns in other forensic sciences: if the prosecution presents a Chainalysis tracing result, how can the defense or an outside observer trust it without insight into how it was produced? Chainalysis has begun to address this by emphasizing the deterministic nature of their algorithms and the fact that many clusters are corroborated by customer-provided data. Nevertheless, the lack of peer-reviewed studies and the proprietary secrecy remain points of contention.
Some privacy advocates and members of the crypto community also object to Chainalysis on ethical grounds. They argue that widespread blockchain surveillance undermines the financial privacy of crypto users, effectively creating a landscape where every transaction is monitored and judged. There is fear that innocent users might be caught in the dragnets—for instance, having their funds flagged simply because they unknowingly received coins that at some point passed through a mixer or were two hops away from a theft. Such false positives could lead to account freezes or investigations of users who did nothing wrong. Chainalysis and similar firms walk a fine line, needing to provide useful data to stop criminals while not overstepping and harming legitimate users’ privacy.
This debate often surfaces in discussions around proposed regulations, where Chainalysis data showing illicit activity rates is used to justify stricter rules, and privacy proponents counter that those rates are relatively low (for example, Chainalysis’s own research showed only 0.15% of crypto transaction volume was illicit in 2021). Some argue that heavy surveillance might be overkill.
Finally, there are operational challenges for Chainalysis as the crypto landscape evolves. The rapid emergence of new blockchains (like the rise of many Layer-1 and Layer-2 networks, or the explosion of tokens/NFTs) means Chainalysis must constantly add support for new assets and update its algorithms for new transaction types. This is resource-intensive and there can be a lag before a very new coin or technology is fully supported. Additionally, criminals are adaptive; they have started using more sophisticated methods like cross-chain swapping (moving illicit funds through decentralized exchanges or cross-chain bridges to obscure their trail by changing currencies). This requires Chainalysis to develop cross-chain tracing capabilities (an active area of development in the industry). The company also faces competition from other analytics firms, which means it has pressure to claim a high ground in accuracy and coverage – any notable miss or mistake can be seized upon by competitors. And as seen with the Sterlingov case, legal challenges to the admissibility and reliability of blockchain forensic evidence may increase, pushing Chainalysis to be more transparent and rigorous. In summary, Chainalysis must continually innovate to trace an ever-moving target (as illicit actors find new ways to hide) while also convincing stakeholders that its findings are solid. The criticisms and limitations highlight that blockchain analysis, though powerful, is not infallible – it should be one tool among many, used carefully and corroborated with other evidence to avoid pitfalls.
Recent Developments
Chainalysis has been actively expanding and adapting its offerings in response to the fast-changing crypto environment, forging partnerships and launching new initiatives in recent years:
Product Innovations: In May 2022, Chainalysis introduced a new tool called Storyline, designed to simplify investigations involving Decentralized Finance (DeFi) and non-fungible tokens (NFTs). Storyline provides a timeline-based visualization of complex smart contract transactions, helping investigators “follow the money” through token swaps, NFT trades, and other advanced on-chain activity that traditional graph tools struggled with. This was timely, as DeFi protocols had become hotbeds for hacks and illicit activity, with over $1.5 billion stolen from DeFi in the first part of 2022 alone.
By launching Storyline, Chainalysis addressed a critical gap, enabling law enforcement and compliance analysts to unravel the often convoluted flow of funds in hacks, such as cross-chain bridge thefts or NFT scams. The tool works in tandem with Reactor, indicating Chainalysis’s focus on staying ahead of criminals’ shift towards new technologies.
More recently, Chainalysis has been integrating artificial intelligence (AI) capabilities into its analytics. In 2023, the company announced it would leverage AI to enhance pattern recognition and entity identification on-chain. It also launched an AI-based sanctions screening tool that can predict and flag addresses likely controlled by sanctioned actors before they are officially listed. This kind of proactive risk mitigation shows how AI might improve detection speed. While maintaining its core deterministic heuristics, Chainalysis is clearly investing in new technologies, like AI and expanded DeFi tracing, to meet emerging threats.
Strategic Partnerships: Recognizing that crypto compliance and investigation often intersect with broader financial systems, Chainalysis has formed alliances with traditional advisory firms. In late 2023, Deloitte and Chainalysis announced a strategic alliance to jointly help clients with crypto compliance challenges. Through this partnership, Deloitte integrates Chainalysis’s blockchain data and analytics software into its risk and forensic services, allowing their mutual clients, including government agencies and financial institutions, to benefit from both Chainalysis’s technical tools and Deloitte’s consulting expertise. The goal is to provide a comprehensive solution for tracing crypto transactions, managing regulatory compliance, and prosecuting crypto-related crimes.
Around the same time, KPMG Canada struck a similar agreement with Chainalysis to bolster forensic investigations of digital assets, particularly to help recover stolen funds and investigate fraud in the crypto space. Another notable collaboration is with AlixPartners, which joined the Chainalysis Partner Program in October 2024. AlixPartners uses Chainalysis tools in its financial investigations and turnaround consulting for clients facing crypto-related fraud or insolvency issues.
These partnerships signal that Chainalysis’s services are increasingly mainstream, as large consulting and accounting firms find value in having in-house blockchain investigative capability via Chainalysis. It also reflects regulators’ expectations that traditional firms incorporate crypto analytics in audits and compliance. By partnering with these firms, Chainalysis extends its reach into clients that might not engage directly with a crypto analytics company but trust firms like Deloitte or KPMG to bring in that expertise. Additionally, Chainalysis has ongoing partnerships with law enforcement worldwide, including training programs and task force support, as well as with cryptocurrency exchanges, some of which proudly announce using Chainalysis to build trust with users and regulators.
Mergers and Acquisitions (Expansion of Capabilities): Chainalysis has made targeted acquisitions to enhance its technology stack. In October 2021, it acquired Excygent, a specialized cybercrime investigative firm that had worked on high-profile cases like the Silk Road darknet market Bitcoin seizures and disruption of terrorist financing campaigns. Excygent’s team brought deep expertise in crypto investigations and data processing, which Chainalysis integrated to offer more hands-on investigative services to government clients. This move bolstered Chainalysis’s ability to provide end-to-end assistance in cases, including both software and expert manpower.
Fast forward to late 2023 and 2024, Chainalysis made further acquisitions in the security and fraud prevention domain. In December 2024, the company acquired Hexagate, a Web3 security firm focusing on smart contract and blockchain protocol security to help identify vulnerabilities and malicious activity on-chain. The following month, in January 2025, Chainalysis announced the acquisition of Alterya, an Israel-based AI-powered fraud detection startup, for a reported $150 million. Alterya specializes in detecting “authorized” frauds and scams—cases where victims are tricked into sending money—by analyzing patterns across both crypto and fiat payment networks. Before the acquisition, Alterya had been working with top exchanges like Binance and Coinbase to monitor over $8 billion in transactions per month, using AI agents to identify scammers in real-time.
By bringing Alterya into the fold, Chainalysis focused more on preventative fraud detection, aiming to stop scams before funds are irretrievably moved on-chain. This marked a slight strategic shift from purely reactive investigation to proactive risk prevention. With Alterya’s technology, Chainalysis can now offer services that flag likely scam-related payments (even in fiat) and help institutions intervene, adding a new layer to its platform beyond traditional blockchain analysis.
These acquisitions illustrate Chainalysis’s drive to remain a one-stop shop for crypto risk management, branching into adjacent areas like real-time fraud prevention and smart contract security, which complement its core analytics.
Regulatory and Market Changes: The regulatory landscape around cryptocurrency has tightened, which has benefited Chainalysis by increasing demand for its tools. For instance, the implementation of the FATF “Travel Rule” in various jurisdictions, which requires exchanges to share sender/receiver information for large transfers, has led exchanges and banks to seek solutions for identifying counterparties. Chainalysis’s data on address ownership has become very useful for this compliance step.
Chainalysis has updated its products to help clients comply with sanctions and reporting rules. For example, when the U.S. Treasury sanctioned crypto addresses associated with North Korean hackers or mixers like Tornado Cash, Chainalysis promptly added those to its watchlists and offered free screening tools for the industry to check for sanctioned exposure. The company also launched features to track emerging typologies like NFT wash trading and rug pulls, as regulators focus on fraud in the NFT space.
On the market side, the steep increase in crypto-related crimes during 2021–2022 and the subsequent high-profile collapses (such as the FTX exchange scandal in 2022) put urgency on compliance and forensic solutions. Chainalysis reportedly worked with bankruptcy administrators in the FTX case to trace billions in missing assets, showcasing its utility in insolvency proceedings.
As of early 2024, Chainalysis’s growth has been reflected in its financials. The company has raised over $530 million in venture funding to date and reached a valuation of approximately $8.6 billion, making it one of the most valuable firms in the cryptocurrency industry.
