Cryptocurrencies like Bitcoin and Ethereum dominate global digital payments, accounting for nearly 80% of transactions in 2021. Unlike traditional banking, cryptocurrency transactions are pseudonymous—wallet owner details are hidden, but transaction histories are public. This guide explores OSINT (Open-Source Intelligence) techniques to identify and track cryptocurrency wallets.
Key Differences Between Cryptocurrencies and Traditional Banking
- Decentralization: No central issuer or government control.
- Pseudonymity: Wallet owner identities are hidden, but transactions are recorded on public ledgers.
- Unlimited Addresses: Users can generate countless wallet addresses.
- Blockchain Technology: Transactions are grouped into blocks, forming an immutable chain (hence "blockchain").
Step 1: Using Blockchain Explorers
Blockchain explorers provide essential wallet data. Universal explorers support multiple cryptocurrencies:
Popular Universal Blockchain Explorers
- Blockchair
- Blockchain.com
- BlockCypher (with Chrome extension)
These tools reveal:
- Wallet address
- Current balance
- Transaction history (dates, amounts, counterparties)
Step 2: Monitoring Inactive Wallets
For wallets with no transaction history, use monitoring services to track activity:
Wallet Monitoring Tools
- Crypto Tx Alert
- Cryptocurrency Alerting
Supported cryptocurrencies: Bitcoin (BTC), Ethereum (ETH), Bitcoin Cash (BCH), Litecoin (LTC).
Step 3: Identifying Wallet Owners
Method 1: Google Dorks
Use advanced search operators to find wallet-linked data:
[wallet_address -block]
[wallet_address_1 | wallet_address_2 -block] Method 2: Review and Scoring Sites
Check these platforms for wallet reputations:
- Bitcoin Abuse (BTC)
- Chainabuse (multi-currency)
- BadBitcoin.org (BTC)
Scoring services assess wallet risk:
- BitRankVerified (BTC, ETH)
- Vivigle (BTC, ETH, BCH, LTC)
Method 3: Attribution to Organizations
Link wallets to exchanges or criminal groups via:
- WalletExplorer (BTC)
- Crystal Blockchain Explorer (BTC)
- Etherscan (ETH)
