The Problem
The most expensive moment in logistics is the one nobody records.
A package from Lagos to Abuja changes hands five or six times before it reaches the customer. Each transfer is a handover — and in most African logistics operations today, none of them produce a receipt that would survive a dispute.
Not because operators are careless. Because the infrastructure for shared custody records between independent companies has never been built. Every logistics platform is designed to solve one company's problem. None of them cover the gap between companies — and that gap is precisely where packages disappear.
The result: disputes that take days to reconstruct from WhatsApp threads, riders who carry blame for things that happened after they left, and cross-operator partnerships that quietly erode because nobody can trust a shared record that doesn't exist.
Between companies
Your system stops having visibility the moment custody crosses to a partner operator.
At scale
Informal processes — WhatsApp, counter signatures — collapse under volume.
At the last mile
"Delivered" is an assertion from the person whose job depends on it, with no independent verification.
How It Works
Three steps. One immutable record. Zero dispute.
01
Dispatcher generates the handover
The dispatcher taps hand over in their dashboard. A QR code appears — a one-time token tied to the specific waybills in the run, expiring in 15 minutes.
02
Rider authenticates and scans
The rider opens Trackam, verifies with their phone number, and scans the QR. Their identity — verified once at onboarding against a government ID — flows automatically from their session. No form. No typed name.
03
Proof hash is recorded
A SHA-256 hash of the waybill ID, both actors, GPS coordinates, and timestamp is written to the shipment's custody chain. Both dashboards update in real time. The record belongs to neither party. It belongs to the shipment.
Features
Every detail built for how logistics actually works.
Cryptographic proof
Every handover produces a SHA-256 hash of the waybill ID, both actors, GPS coordinates, and timestamp. Immutable. Auditable. Belongs to the shipment.
Verified identity
Riders verify their government ID once at onboarding. From that point identity flows automatically from their authenticated session — never collected at handover.
Cross-operator chain
When custody crosses company lines, both operators record the same event through OLI Switch. The chain follows the package, not the platform.
GPS-stamped events
Location is captured silently at the moment of transfer. Every proof hash carries coordinates — no button tap required from the rider.
Public tracking, private PII
The custody chain is public. Sender and receiver details are revealed only after OTP verification — protecting privacy without hiding accountability.
Batch handovers
Dispatch runs hand off multiple shipments in one event. Every waybill in the batch gets its own proof hash, simultaneously, in a single scan.
Who It's For
Every actor in the chain feels the handover problem differently.
Dispatcher
Before
You send 20 runs. You have no confirmation any of them actually transferred.
With Trackam
Know the moment a rider accepts custody. Open any dispute in seconds with a timestamped, GPS-stamped proof chain.
Hub Operator
Before
Packages arrive from partners whose systems don't speak to yours. Accountability stops at your door.
With Trackam
Every incoming transfer from any operator on the OLI network records against your instance. The chain doesn't break at company boundaries.
Logistics CEO
Before
A customer calls at 6pm. A package is missing. Nobody can agree on who had it last.
With Trackam
Open the waybill. See every hand it passed through — names, timestamps, locations. Disputes resolve in 30 seconds instead of 3 days.
The Network
The chain follows the package — not the platform.
Each operator runs their own private Trackam instance. Their data stays on their server. Nobody else sees their business.
But when custody crosses from one operator to another, both instances connect through the Open Logistics Interconnect — OLI Switch. Both record the same handover event simultaneously. The proof hash is identical on both sides.
A package moving through four companies has one auditable custody chain that no single company controls and no single company can edit.
The chain is shared. Nobody controls it.
The Technology
Open source. Self-hosted. Nothing hidden.
Trackam is MIT-licensed and fully open source. You can read the handover logic, the hash generation, the OTP flow, the custody chain. Every line.
Operators own their infrastructure. Your riders, your waybills, your database — on your server. One-command Railway deployment for managed hosting, or a full self-hosted path for complete control.
