01 / THE BUSINESS CHALLENGE

Where the friction was.

Reconstruct a value flow and make the reasoning inspectable without confusing wallet behaviour with proven identity.

02 / THE CONNECTED SOLUTION

How the pieces connect.

Group transactions by time, amount and counterpart; map the paths of value; distinguish observed transfers from hypotheses about services. Package the findings into a structured summary that other analysts can retrace against the public ledger.
