Case Type: Civil litigation / financial fraud
involving cryptocurrencies

Client: Commercial litigation law firm

Parties Involved: Client vs. former business partner

Mandate Assigned to H2E Firm:

Track and document the movement of funds transferred in cryptocurrencies (Ethereum and Bitcoin)

Duration of Mandate: 
20 business days

Context

An entrepreneur alleged that his former associate had, without authorization, transferred the equivalent of CAD $58,000 in cryptocurrencies from a jointly held wallet to anonymous addresses.


The client’s goal: demonstrate the origin and destination of the funds before the court in support of a motion for injunction and seizure.

H2E Firm was hired to conduct a full analysis of the blockchain transactions, link addresses to known platforms, and produce a court-admissible report.

H2E Firm’s Intervention

Step 1

Evidence Collection

  • Retrieval of the source wallet (public address) and the list of disputed transactions
  • Cross-verification with provided screenshots and email excerpts
  • Preservation of evidence via timestamping and IPFS capture
Step 2

Blockchain Analysis

  • Tracing of over 30 transactions on the Bitcoin and Ethereum blockchains
  • Use of specialized tools (Blockchair, Chainalysis Reactor, Etherscan Pro)
  • Identification of entry into centralized exchanges (Binance, Kraken)
  • Detection of mixers and attempts to fragment amounts (money laundering pattern)
Step 3

Report and Deliverables

  • Full forensic report including:
  • Timestamped list of transfers with CAD value at time of sending
  • Visual mapping of the flows (source address → steps → destination)
  • Probability analysis of control (indirect ownership by the associate)
  • Annex of preserved evidence in JSON, CSV, and signed screenshot formats
Outcome

Thanks to H2E’s report, the judge authorized
a precautionary seizure at two exchange platforms, enabling the partial freezing of
the funds.


The case is still ongoing, but the technical intervention was deemed admissible, relevant, and “essential to understanding the financial movements,” according to court comments.
