MERCHANT TRUST INFRASTRUCTURE

Continuous Trust Infrastructure for Africa's Food Economy

Food delivery platforms onboard thousands of merchants — but trust verification stops at day one. Evodira provides the continuous, evidence-based trust layer that keeps platforms, merchants, and consumers aligned.

The Trust Gap
Platforms verify merchants once — then assume compliance forever

Assumed compliant

How Evodira Works
Four steps from integration to continuous trust
1
Platform Integrates
Connect your marketplace via our RESTful API. Submit merchant profiles, evidence, and complaints with a few API calls.
2
Evidence is Captured
Merchants and field inspectors submit geotagged photos, documents, and liveness videos through trusted capture.
3
AI + Human Review
Six AI model families assess evidence quality, scene correctness, and fraud signals. Human reviewers make all high-impact decisions.
4
Continuous Trust Scores
A 9-component risk score updates continuously. Embeddable badges, webhook alerts, and public trust status keep everyone informed.
Everything You Need for Merchant Trust
A complete infrastructure layer — from onboarding to continuous monitoring
Merchant Onboarding
KYC, business verification, address resolution, and initial evidence collection — all via API.
Evidence Pipeline
Structured photo capture with 6 AI models: quality gate, scene classification, object detection, condition scoring, fraud detection, and duplicate matching.
Complaint Intelligence
Auto-classification by category and severity. Cluster detection surfaces repeat offenders. Safety-critical complaints escalate instantly.
Risk Scoring
9-component composite score: identity, location, evidence integrity, operational risk, complaints, fulfilment, reputation, external signals, and behavioural anomalies.
Human Review Console
QC reviewers and leads adjudicate flagged merchants with full evidence context. Second review for high-impact decisions.
Trigger Investigations
Automated rules fire on complaint spikes, location drift, evidence staleness, fraud signals, and more. Each creates a review case.
Public Trust Badges
Embeddable SVG/HTML badges display conservative trust status: Verified, Under Review, Limited Confidence, or Suspended.
Webhook & Platform API
Subscribe to 8 event types. Receive real-time alerts on status changes, trigger fires, evidence reviews, and corrective actions.
Audit Trail
Every action is logged with actor, timestamp, previous state, and new state. NDPA-compliant, tamper-evident, queryable.
Built for Every Stakeholder
Whether you're a platform, merchant, regulator, or consumer

Governance & Compliance
Responsible trust infrastructure aligned with African regulatory frameworks
NDPA Compliance
Lawful basis for processing, data minimisation, retention limits, DPIA for high-risk profiling, and data subject rights including appeal and deletion.
NAFDAC Alignment
Observable controls framework aligned with NAFDAC Food Hygienic Practices guidelines. We score what's visible — never claim lab-grade food safety.
NiCFoST Standards
Inspection methodology based on NiCFoST professional-operational baselines: physical presence, premises registration, and expert audit methods.
Human-in-the-Loop
AI supports risk prioritisation and evidence assessment. All high-impact decisions — suspensions, approvals, corrective actions — require human review.
Data Retention Policy
Raw media: 180 days. Hashed manifests and adjudication records: 24 months. Audit logs: up to 7 years. Face blurring by default on exports.
Appeal Rights
Every merchant can appeal any adverse decision. Appeals are reviewed by a different reviewer. No materially adverse status is published without human review.
