TL;DR

• We shift the focus from following funds on-chain (which often stalls at mixers) to infrastructure pivoting: finding where a wallet address is published on the web.
• You will learn manual techniques using block explorer comments and exact-match search queries.
• We show how the UserSearch Cryptocurrency and Domain Intelligence Search types help you connect an address to domains, hosting and support chat services.
• Two worked scenarios: mapping a fake trading platform network and attributing a video giveaway campaign to shared hosting.

The Industrial Scale of Crypto Fraud

Crypto fraud today looks less like a lone operator and more like a business. The groups behind it have support scripts, marketing teams and a lot of technical infrastructure: websites, chat widgets, messaging bots and hosting accounts.

For analysts, that shift is useful. A wallet address is no longer just a destination for payments. It is one point in a wider network that includes lookalike domains, servers, support email addresses and social media accounts. Attribution rarely comes from following funds on the blockchain alone. It comes from pivoting from that permanent ledger back to the web infrastructure that serves the operation.

In this guide, we go beyond basic block explorer lookups. We show how to take a questionable wallet address and map it to the "Web2" infrastructure behind it (domains, IP addresses and email addresses) using manual OSINT techniques and the UserSearch platform.

What Is Wallet-to-Infrastructure Pivoting?

Many newcomers treat cryptocurrency research as a purely on-chain activity. They open Etherscan, follow ETH from Wallet A to Wallet B, and reach a dead end when the funds enter a mixer such as Tornado Cash or a high-volume exchange.

Wallet-to-Infrastructure Pivoting turns this approach around. Instead of asking "Where did the money go?", we ask "Where did this address appear?"

Nobody sends money to a random hex string without context. The operators need a way to deliver the address: almost always a website, a Telegram bot, a Discord server or a spoofed support email. By finding where the wallet address is published, hosted or hardcoded, we can map the web infrastructure behind the operation.

For a related look at working from technical signals back to the organisations behind them, see our guide on Wireless OSINT, which applies similar principles to Wi-Fi and Bluetooth data.

Why It Matters: Attribution in the "Pig Butchering" Age

The stakes are high. The FBI's Internet Crime Complaint Center (IC3) reported that investment fraud (mostly crypto-related) caused $3.31 billion in losses in 2022 alone. A significant portion comes from "Pig Butchering" schemes (Sha Zhu Pan), where people are persuaded over months to invest through fake crypto exchanges.

In these cases, the wallet address is often the only solid indicator the paying party has. The friendly contact on WhatsApp does not exist. The "trading platform" app was sideloaded. But the wallet address that received $50,000 is real, and it is permanently recorded on the blockchain. Linking that wallet to a specific domain (for example fake-exchange-support[.]example) allows analysts to:

• Identify the registrar and hosting provider, so that legal teams or authorities can send formal requests.
• Find other paying wallets interacting with the same domain.
• Connect the domain with other operations run by the same group.

The Manual Method: Block Explorers and Dorks

Before using a platform, it is worth understanding how to extract intelligence from a wallet address by hand, using block explorers and search engines.

1. "Follow the Money" via Block Explorers

Your first stop is the block explorer native to the chain (for example Etherscan for Ethereum, BscScan for BNB Smart Chain, TronScan for TRON).

Step A: Check the Comments Section
Etherscan has a "Comments" tab for every address. People who have lost money often post warnings there soon after paying.

Step B: Analyse the Transaction Graph
Look at the "In" and "Out" transaction volumes. A collection wallet often shows a high frequency of incoming small-to-medium payments and occasional large outgoing transactions (sweeping funds to a master wallet or an exchange).

2. Google Dorking the Address

The operators have to share the address somewhere. Often this happens in private chats, but it also appears on public forums, in "giveaway" video descriptions, or on fake "support" sites. We can find these mentions with exact-match searching.

The Basic Dork:

"0x1234567890abcdef1234567890abcdef12345678" -site:etherscan.io -site:bscscan.com

Note: We exclude the block explorers themselves to reduce noise.

The Context Dork:
If you expect a specific kind of scheme (for example a fake giveaway), add keywords:

"0x12345678..." AND ("giveaway" OR "double your eth" OR "support")

3. Searching Community Report Databases

Several community-driven databases record reported addresses. Manual checks here can confirm whether an address is already known.

• BitcoinAbuse.com: Primarily for BTC, recording wallets that users have reported for abuse.
• Chainabuse: A multi-chain reporting platform covering everything from rug pulls to fake investment sites.

This works, but it is slow. You have to check multiple chains and multiple databases, and write dozens of search queries to get a complete picture. This is where a platform that brings sources together earns its place.

The Pivot: Wallet Intelligence with UserSearch

UserSearch brings these checks into one structured workflow, with access to 100+ third-party data sources through one account. Instead of only seeing funds, you see the websites associated with the wallet.

Step 1: The "Address Lookup" Module

This Module acts as your initial triage. It checks reporting sources to see whether the address has been flagged before.

1. Open the Cryptocurrency Search type.
2. Select the Address Lookup Module.
3. Paste the wallet address under review (BTC, ETH and major EVM chains).
4. Review Results: If the address has been reported, you will often see a category (for example "phishing") and sometimes a description of the method used.

Step 2: The "Websites by Address" Pivot

This is the most useful pivot in the crypto-OSINT workflow. The Module returns websites that its data source has observed displaying a specific wallet address, so you can work backwards from a wallet to the domains using it.

1. Switch to the Websites by Address Module.
2. Enter the wallet address.
3. Analyse the Hits: The results list domains where the address has been seen.

Why does this matter?
If you search for a wallet and find it listed on token-giveaway[.]example, you have moved your research from the blockchain (pseudonymous) to the web (registrable). You now have a domain to research. Treat the hit as a lead to corroborate: coverage and freshness depend on the third-party source.

Step 3: Domain Research

Once you have a domain from the previous step, you can pivot to the Domain Intelligence Search type in UserSearch to take the research further. (See our guide on Domain OSINT for a full breakdown of this process.)

• Domain Ownership: Check historical WHOIS data. Even if the current record is privacy-protected, a record from six months ago might show an organisation name or email address.
• Website Change History: See what the site looked like while the operation was active. These sites often go offline quickly, so historical snapshots are valuable evidence.
• Shared Third-Party IDs: Check whether the site uses the same Google Analytics or AdSense ID, or the same favicon, as other reported sites. This lets you map the wider network run by the same group.

When a page matters as evidence, capture it with Forensic Capture, our free browser extension that records full-page captures with SHA-256 fingerprints and independent timestamps.

Worked Scenarios from Crypto Infrastructure Research

To show how these techniques work in practice, here are two common patterns. The organisations, domains and addresses are fictional.

Scenario A: The "Fake Exchange" Trading Platform Network

The Context: A payments compliance team at a fictional fintech, Harrowgate Pay, receives a customer report of $100,000 USDT sent to an Ethereum address: 0xAbCd....

The Actions:

1. Manual Check: Etherscan shows millions of USDT flowing in from many addresses and out to a known exchange hot wallet. This confirms high-volume activity but does not identify the operator.
2. UserSearch "Websites by Address": Querying the address shows it is hardcoded on defi-trading-pro[.]example.
3. Domain Pivot: Running defi-trading-pro[.]example through the Domain Ownership Module shows it was registered three months ago via Namecheap.
4. Infrastructure Map: A third-party ID check shows the site uses a specific Tawk.to chat widget ID. Searching this ID shows 15 other domains (for example crypto-elite-trade[.]example and gold-futures-invest[.]example) using the same support widget.

The Outcome: The team identifies a cluster of 16 fake trading sites run by the same group, all tied back to the single wallet address in the customer report, and passes a documented report to the authorities and the hosting providers.

Scenario B: The Video Giveaway Campaign

The Context: A brand protection analyst at a fictional exchange, Kestrel Digital, finds a wallet receiving small amounts (0.1 ETH) from hundreds of senders after a fake giveaway uses the exchange's name.

The Actions:

1. UserSearch Address Lookup: Returns reports tagging the address as a "celebrity giveaway".
2. Search Query: The analyst runs "0xAbCd..." site:youtube.com. The results show 50+ videos, uploaded by different accounts, all featuring the same synthetic footage of a well-known figure promoting the giveaway.
3. Pattern Recognition: All the videos link to bonus-event[.]example.
4. UserSearch Domain Intelligence: Researching the domain shows it shares a hosting IP with 200 other "giveaway" domains, confirming a large automated campaign.

The Outcome: The analyst files takedown requests with the platform and the host, supported by timestamped captures and a list of linked domains.

Legal and Ethical Guardrails

When researching crypto fraud, you are often looking at infrastructure run by organised groups. Good operational security (OPSEC) matters.

• Keep Your Distance: Open reported domains only inside a virtual machine (VM) with a VPN, not in your everyday browser. These sites can host malicious code.
• Passive Research: UserSearch queries third-party data sources rather than the live site, so your own IP address does not appear in the operators' logs.
• Stay Within the Law: Limit your work to information gathering, documentation and reporting to the competent authorities (for example FBI IC3 or your national cybercrime reporting centre). Action against the operators' systems or funds is a matter for law enforcement, not for private analysts.

From Wallet to Network: Research with UserSearch

Cryptocurrency research is no longer only about following the money; it is about following the infrastructure. The wallet address is the thread that, when pulled, can reveal a whole network of domains, servers and operators. By combining manual blockchain analysis with the web-to-wallet pivots in UserSearch, analysts can move faster and document their findings properly. Do not stop at the ledger: find the network behind it.

Stop guessing. Start researching with UserSearch.
