Truvend

Trade with Trust.

An AI-powered marketplace that protects buyers and empowers sellers through intelligent trust scoring and secure escrow payments.

Built for the Nomba × DevCareer Hackathon 2026.

---

Overview

Every day, millions of Nigerians buy and sell through Instagram, WhatsApp, Facebook Marketplace, and classified platforms.

The biggest problem isn’t discovery,

It’s trust.

Truvend solves this by combining:

• AI-powered fraud detection

• Trust scoring for every listing

• Escrow-powered payments

• Real-time transaction monitoring

Instead of asking buyers to “trust the seller,” Truvend helps them verify before they pay.

---

The Problem

Current social commerce platforms suffer from:

• Fake vendors

• Manual bank transfers

• No buyer protection

• No dispute resolution

• High checkout abandonment

• Low trust

As a result:

• Buyers lose money.

• Sellers lose genuine customers.

• Platforms lose credibility.

---

Our Solution

Truvend introduces two major innovations:

AI Trust Engine

Every listing is analysed before payment.

The AI evaluates:

• Product pricing

• Listing quality

• Seller history

• Image authenticity

Each listing receives a Trust Score from 0–100 together with an easy-to-understand explanation.

Smart Escrow

Payments are protected through a 48-hour escrow powered by Nomba.

Funds are released only after successful delivery.

If a dispute is raised, payment remains protected until resolution.
