Blockchain tracing
A transaction hash acts as a reference to a specific on-chain event. Depending on the network, investigators can examine the sending address, receiving address, amount, timestamp and later movements. Repeated analysis can create a chronological map of where assets travelled.
The visible ledger is only one part of an investigation. It may show movement without revealing the real-world identity behind an address.
Cross-network movement
Funds can move through bridges, swaps, contracts and different blockchain networks. Following these transitions requires connecting events across the relevant networks rather than treating each transaction as an isolated record.
Complexity increases when assets are routed through services designed to reduce transparency or when activity moves into networks with limited public visibility.
Exchanges and custodial services
When assets reach a centralized exchange or other identifiable service, the on-chain record may provide a lead. Additional account-level information is normally controlled by the service and may only be available through its internal processes or lawful requests.
A blockchain address should therefore be treated as an investigative lead, not as automatic proof of a person's identity.
Preserving evidence
Keep the original transaction hashes, wallet addresses, dates, amounts, screenshots, emails, chat records, invoices, account statements and details of how the transfer was requested. Preserve original files where possible rather than relying only on screenshots.
Never share private keys, seed phrases or authentication codes with an investigator, recovery service or person claiming to help.
