The problem

Every day, real people lose real money.

Across Nigeria, trade happens on WhatsApp, Instagram and Telegram — with no infrastructure protecting either side. These are not edge cases. They are the everyday reality of digital commerce, and the result is billions lost annually.

The seller

Chioma

sells fashion on Instagram

A buyer asks for a ₦35,000 dress and sends a screenshot showing payment. Under pressure — messaged every two minutes — Chioma ships before checking her account. The money never arrived. The screenshot was fake. No record, no recourse.

Loses ₦35,000 · twice a month
The buyer

Emeka

buys a phone on WhatsApp

He transfers ₦28,000 directly to the seller's account for a phone. The seller goes quiet, then blocks him. No evidence, no contract, no platform to escalate to. His bank says the transfer was authorised. He lost everything.

The solution

Three layers. One promise. Zero fraud.

LAYER 01

TrustPay

Protects the money
  • Buyer locks funds in a secure OPay-backed vault before goods move
  • Seller sees money is real — no fake screenshots possible
  • Buyer shows QR on delivery, seller scans, funds release instantly
  • Transfers above ₦50,000 require facial recognition
LAYER 02

Chëkd AI

Protects the transaction Powered by Google Gemini
  • Gemini reads WhatsApp / Instagram / Telegram chats and extracts the order
  • Analyzes payment screenshots for tampering in real time
  • Detects identity fraud and suspicious behaviour patterns
  • Auto-generates invoice, updates inventory, records the customer
LAYER 03

Fraud Intelligence

Protects the platform
  • Captures facial data + device fingerprint on a fraud attempt
  • Records precise location at the point of fraud
  • Builds a permanent profile and blacklists the fraudster network-wide
  • Packages evidence ready for law-enforcement reporting

How it works

From chat to cash in six steps.

STEP 01

Paste chat

Seller pastes the WhatsApp conversation straight into Chëkd.

STEP 02

AI extracts

Gemini reads the chat and pulls out the full order — item, price, buyer.

STEP 03

Lock funds

Buyer gets an OPay link and locks the funds safely in the vault.

STEP 04

QR delivery

Seller delivers, buyer shows a QR code, seller scans to confirm hand-off.

STEP 05

Release

Money releases to the seller's OPay account instantly — no waiting.

STEP 06

Auto-record

Invoice generated, inventory updated, customer saved. Zero manual work.

Trust score

A score that reflects real behaviour.

Every user starts at 100. Each completed trade builds your behaviour record. Reports and disputes move it down — fast. Before any trade starts, your counterparty sees your score. A low score means sellers can refuse you, and buyers can walk away. Hit zero and your account, device, and face are permanently flagged.

All four domains — naturally.

Most teams pick one domain. Chëkd addresses all four organically — not by design, but because the problem demands it.

The mission

We're not building another app. We're building the trust layer African commerce has always been missing.

Try the six-step flow yourself — paste a chat and watch a transaction go from fraud-prone to fully protected, in under a minute.
