Fraudsters reuse the same numbers across shops. KODA's shared fraud network turns confirmed abuse at one merchant into a privacy-preserving warning for all.

A fraudster rarely targets just one shop. They work a market. The same line, the same edited screenshot, the same recycled number moves from stall to stall down the same street, and each merchant meets it fresh with no idea that the trader next door was hit yesterday. Isolated, every shop relearns the same lesson at its own expense. Networked, the first flag protects everyone who comes after. That is the simple idea behind KODA's shared fraud network.
The mechanics are built for privacy from the ground up. When abuse is confirmed at a participating merchant through a quarantine, a lost dispute, or a reference code caught being reused, KODA extracts a masked, aggregated risk signal about that counterparty. No raw customer data, no message contents, no personal details are shared between merchants. What travels is only an elevated risk score tied to the offending party, consistent with the privacy posture that underpins How KODA verifies mobile money payments. The next time that counterparty tries to pay one of your orders, their history arrives with them.
Think of it as extending the fraud engine beyond the walls of a single shop. The velocity and pattern work in How KODA Catches Coordinated Payment Fraud already spots an attacker probing one merchant. The network takes the conclusion of that work and shares the warning, so an attacker who has been burned at three shops in a corridor arrives at the fourth already carrying an elevated score. They do not get to start from zero at every new counter, which is exactly the fresh start that made market-hopping fraud profitable.
This matters because mobile-money fraud in Africa is fundamentally a corridor problem, not a shop problem. Across operators like M-Pesa, Orange Money, Airtel Money, Africell and MTN MoMo, the same tactics circulate through the same neighbourhoods and trading networks. A defence that ends at your own front door will always be one step behind people who move freely between doors. Pooling confirmed signals is the only way for honest merchants to match the mobility that fraudsters already enjoy.
A fair question is whether joining exposes your business or your customers. It does not. The network is opt-in and shares no identifiable customer information; it moves only masked, aggregated risk indicators derived from confirmed abuse, never ordinary transaction data or the details of your genuine buyers. Your legitimate customers are unaffected, because normal trade produces no such signals. Only counterparties who have been confirmed as abusive, through real evidence, ever raise a flag that others can see.
The confirmed cases that feed the network are not guesses. They come from the assembled evidence behind Win Mobile Money Disputes with an Automatic Evidence File and from the arithmetic anti-forgery defence in How KODA Catches Fake Payment SMS, so a flag reflects a payment that failed a real test, not a merchant's bad mood. This keeps the shared signal trustworthy: the network is only as valuable as the quality of what goes into it, and grounding it in hard verification evidence keeps false alarms low.
The effect is a shield that gets stronger as it grows. Every merchant who joins adds their confirmed cases to the pool and draws on everyone else's in return, and wider KODA global coverage — operators & countries across more markets and operators means fewer places for a repeat offender to hide. A network of a hundred shops sees a hundred times the attack surface that any one of them could see alone, and turns that visibility into protection for all of them. This is the same dynamic that makes any real network valuable: the cost of joining is small and fixed, while the benefit grows with every other participant. A lone shop is always reacting to attacks it has never seen before, but a connected shop inherits the accumulated caution of everyone who came before it, so newcomers are protected from day one rather than paying tuition in lost stock.
You do not have to face the market's fraudsters one shop at a time. Join the pool, contribute your confirmed cases, and let the corridor's collective memory work for you. Get started with KODA free with KODA and opt into the shared fraud network for free, so the next attacker who has already been caught elsewhere arrives at your counter already flagged.
When a counterparty is repeatedly flagged across merchants, KODA raises risk on their future payments to you too — before they cost you anything.
No raw data is shared. The network uses masked, aggregated risk signals only, consistent with the privacy posture behind How KODA verifies mobile money payments.
