For telcos, fintechs & banks
See the fraud your competitors already confirmed.
Fraudsters reuse the same numbers, wallets and IDs across networks — and today each institution discovers them alone, one loss at a time. Masenu members share confirmed fraud signals on hashed identifiers, so the first confirmed report anywhere becomes protection everywhere.
Why join
After the first member confirms a fraudster, every other member is warned on first contact. Cross-network reuse — the fraudster's biggest advantage — stops working.
You share one-way keyed hashes, never raw customer data. Attribution is sector + country only — contributing never names your institution or advertises an incident.
Masenu is a private consortium platform, not a regulator: no enforcement power, no competing product, and give-to-get rules that apply equally to every member.
What membership includes
Score any identifier before onboarding or payout — allow / step-up / review / block with human-readable reasons. Engineered for p95 under 150 ms.
Contribute validated fraud reports with evidence. Corroboration-weighted scoring means no single reporter can condemn an identifier alone.
Entity resolution and ring detection across the whole network — including agent collusion patterns no single institution can see in its own data.
Signed SFIX webhooks, SSE and polling. When an identifier you've transacted with is later confirmed fraudulent, you know within seconds.
A built-in dispute workflow protects the innocent; reporter trust scores and anomaly monitors protect the pool from poisoning.
Append-only hash-chained audit, access-review exports, retention certificates — evidence your own auditors and regulators can sample.
Integration in three steps
Scoped API keys plus the hashing SDK: canonical normalization and HMAC-SHA256 with the consortium pepper, run inside your infrastructure. No engineers available? The offline Edge Hasher runs entirely in a browser — nothing leaves your machine.
Download the offline Edge Hasher →POST /v1/lookups before money moves; POST /v1/reports when your team confirms fraud. RFC 7807 errors, idempotency keys, sandbox keys for staging.
Register a webhook endpoint and receive signed exposure alerts, ring updates and dispute events — replay-protected, at-least-once.
