In the world of blockchain analysis, understanding the true risk profile of a cryptocurrency address goes far beyond its immediate transaction history. While examining direct counterparties is essential, it only tells part of the story. To gain a comprehensive view, analysts must also evaluate indirect exposure—the hidden connections that reveal how funds have traveled through complex chains of wallets before reaching or leaving a target address.
Chainalysis Reactor, a leading blockchain investigation tool, helps compliance and investigative teams visualize this full picture using exposure wheels. These intuitive charts break down an address’s interactions into categories such as exchanges, merchant services, darknet markets, and known hack-related wallets. But what sets Reactor apart is its ability to distinguish between two critical layers: direct exposure and indirect exposure.
Direct exposure refers to the services or entities that transact directly with the target address—clear, first-degree relationships visible on the blockchain. Indirect exposure, however, uncovers second- or third-degree connections by tracing funds through unattributed, non-service addresses until they reach a known entity. This deeper layer of insight is vital in detecting obfuscated criminal activity and assessing real-world risk.

What Is Indirect Exposure?
Indirect exposure measures the origins or destinations of funds involved in a target address’s transactions—even when those paths include one or more intermediary addresses not linked to any identifiable service or entity. For example, if Address A sends funds to Address B (a private wallet), which then forwards them to a darknet market, Address A gains indirect exposure to that illicit service.
Because blockchain transactions are public and immutable, tools like Chainalysis Reactor can follow the money trail across multiple hops. Once funds pass through a known service—such as an exchange—the trail typically ends, as internal movements within centralized platforms aren’t publicly traceable. Therefore, services act as logical "stopping points" for indirect exposure calculations.
This capability is unique to cryptocurrency analysis. In traditional finance, intermediaries often obscure fund origins due to privacy policies and fragmented data access. With crypto, transparency enables compliance teams to see further upstream and downstream, giving them a powerful advantage in identifying suspicious patterns—even when bad actors attempt to hide.
Why Indirect Exposure Matters in Risk Assessment
Cybercriminals frequently use self-hosted wallets and layered transactions to distance themselves from illicit sources. By routing funds through several personal addresses, they create the illusion of separation from illegal activity. However, indirect exposure cuts through this deception.
Consider a scenario where a user receives funds from a ransomware payout. They send the money through five different private wallets, each creating new addresses automatically (often due to change outputs), before finally depositing into an exchange. To a basic analysis, the exchange deposit appears clean—no direct link to crime. But indirect exposure reveals the full path: the originating source was criminal, and the chain of hops was merely a smokescreen.
This is where peel chains come into play—a common obfuscation technique where small amounts are peeled off at each hop while the remainder continues forward. These patterns mimic legitimate change handling but are often used to launder money incrementally. Without indirect exposure tracking, peel chains can easily go unnoticed.

Peel Chains: When Change Addresses Hide Criminal Activity
Peel chains illustrate why indirect exposure isn’t just helpful—it’s necessary. In blockchain systems like Bitcoin, when a transaction doesn’t spend an entire input amount, the leftover funds go to a new “change address” generated automatically by the wallet software. Over time, users accumulate many such addresses.
Bad actors exploit this behavior by designing long chains of transactions where tiny amounts are sent outward (simulating normal usage) while most funds continue toward illicit destinations. To the untrained eye, these look like routine operations involving multiple independent wallets. But Chainalysis Reactor’s indirect exposure model detects these patterns and flags them for deeper review.
For instance, imagine investigating an address labeled "17YRUST..." that appears several hops away from Hydra, a now-defunct darknet market. At first glance, seven intermediary addresses suggest significant separation—enough to assume safety. But upon closer inspection, all intermediaries belong to the same wallet cluster. This is a classic peel chain.
Once these addresses are merged under a single entity, the connection becomes undeniable: the target address is effectively one step removed from Hydra. Without indirect exposure highlighting this link, investigators might miss a crucial red flag.
Update: Chainalysis Reactor now includes automated peel chain detection, making it easier than ever to identify and dismantle layered obfuscation tactics.
The Bigger Picture: Comprehensive Risk Intelligence
Direct transaction analysis remains foundational—but it's insufficient on its own. Relying solely on direct counterparties leaves blind spots that criminals are all too happy to exploit. Indirect exposure closes those gaps by revealing the broader ecosystem surrounding an address.
For compliance teams, this means better-informed decisions about whether to allow deposits, flag accounts, or file suspicious activity reports. For law enforcement, it enables faster attribution and stronger evidence building during investigations.
Moreover, understanding both types of exposure supports regulatory adherence under frameworks like FATF’s Travel Rule, which requires virtual asset service providers (VASPs) to collect and share sender and recipient information. Indirect exposure provides context beyond raw data, helping institutions assess not just who they’re dealing with—but where those funds have truly been.

Frequently Asked Questions (FAQ)
Q: What’s the difference between direct and indirect exposure?
A: Direct exposure involves entities that transact directly with the target address. Indirect exposure traces funds through intermediate wallets until they reach known services or illicit entities—even if multiple hops separate them from the original address.
Q: Can indirect exposure generate false positives?
A: While rare, indirect exposure may highlight connections that aren’t malicious—such as receiving funds from someone who once interacted with a high-risk service. Contextual analysis is key to determining actual risk.
Q: How does Chainalysis determine when to stop tracing funds?
A: Tracing stops when funds enter a known service (like an exchange), as internal movements within centralized platforms aren’t publicly visible on-chain.
Q: Are self-hosted wallets always risky?
A: No. Most crypto users rely on self-hosted wallets for privacy and control. Risk arises only when those wallets show consistent links to illicit ecosystems via direct or indirect exposure.
Q: Does indirect exposure work across all blockchains?
A: Yes—tools like Chainalysis Reactor support multi-chain analysis, allowing indirect exposure tracking across major networks including Bitcoin, Ethereum, and select layer-2 solutions.
Q: How can I reduce indirect exposure risks for my business?
A: Implement robust blockchain monitoring tools that assess both direct and indirect risk indicators. Regular audits, transaction screening, and employee training also strengthen defenses.
