CHAIN OF CUSTODY

An unbroken line,
every handoff.

From collection to courtroom, every transfer is a signed entry that hash-links to the one before. One altered byte breaks the chain — and the chain tells you exactly where.

HOW IT WORKS

A ledger nobody can rewrite.

01
Record

Every handoff is captured as a signed, timestamped ledger entry.

02
Chain

Each entry hash-links to the one before it — an unbreakable order.

03
Verify

The whole chain re-validates on demand and flags any break.

04
Defend

Present an unbroken, court-admissible record on request.

WHAT IT GUARANTEES

Admissibility, by construction.

Signed handoffs

Who, what, when, and why — cryptographically attributed to a person.

Hash-linked ledger

Entries reference the prior hash, so order and content are locked.

Tamper detection

Any alteration breaks the chain and pinpoints the exact entry.

Court-ready export

A complete custody report with verification, formatted for filing.
