Tab 1 — Conference Pitch
What to Say — Exact Scripts
Three situations. Three scripts. Learn them or read them from your phone. The goal is not to sell — it's to make ATAF want to follow up.
Key positioning: You are not selling software. You are proposing that ATAF funds the development of an open-source infrastructure that all 44 member countries can use — at a fraction of what Chainalysis charges South Africa alone ($50,000/year for one country).
Situation 1 — After your presentation (2 minutes)
Script — Closing Statement
"What you've seen today is a working prototype built to demonstrate the concept. The core innovation — reconstructing the fiat-crypto cycle from entry and exit points, without full blockchain monitoring — is technically proven and available right now at ndriresearchlab.ddns.net/crypto_conference.
I am not here to sell software. I am here to propose that ATAF funds the development of an open-source tax intelligence infrastructure that all 44 member countries can use — at a fraction of what Chainalysis charges South Africa alone. I propose a 3-phase pilot starting with one volunteer country. The investment for Phase 1 is approximately $80,000 to $150,000 — one technical assistance grant. I have a concept note I can share this week."
— Anthelme N'DRI · ATAF Conference 2026
Situation 2 — Hallway / informal conversation
Script — The 30-Second Elevator
"Three things. First: a dashboard that connects mobile money data, exchange KYC, and blockchain analytics to reconstruct taxable cycles automatically. Second: a risk scoring engine that tells tax administrators who to audit first — no wasted resources. Third: a VASP data request module that automates the legal process of requesting transaction data from exchanges like Binance. The data pipeline uses free public APIs, and VASP data comes through agreements that BCEAO already partially put in place with Instruction 2023. It works from day one."
Situation 3 — Q&A / Skeptical question
"But you don't have real data — this is just a demo?"
"Correct. The prototype uses simulated data to demonstrate the logic. A real deployment connects to Etherscan API, Blockchair API, and direct exchange data feeds — all of which have free tiers sufficient for a pilot with one country. The mobile money data requires bilateral agreement with telecoms — but BCEAO already has this relationship through its 2023 VASP instruction. Phase 1 is precisely about building those data pipelines with one partner country."
"How is this different from what Chainalysis offers?"
"Chainalysis Reactor costs $50,000+ per year and is designed for advanced enforcement agencies like the IRS or Europol. In Africa today, only South Africa uses it. My system has three key differences: it is designed from the start for African administrative capacity constraints; it focuses on the fiat-crypto bridge — mobile money to exchange to bank — which is the African-specific challenge; and it is open-source, meaning all 44 ATAF member countries share the infrastructure cost rather than each paying $50K individually."
"What legal framework does this require?"
"The system operates in three layers. Layer one — public blockchain data — requires no legal authorization. It is publicly readable, like reading a property registry. Layer two — exchange KYC data — requires the VASP licensing framework that BCEAO put in place in May 2023. Once an exchange is licensed, the tax authority can request data through standard administrative procedures, the same way they request bank records today. Layer three — mobile money data — requires a bilateral agreement between the DGI and the telecom operator, which several countries have already done for other tax purposes. We are not inventing a new legal framework. We are using what already exists."
"Which country would pilot this first?"
"My recommendation is Côte d'Ivoire for three reasons. First, BCEAO — which governs the entire UEMOA zone — held its international crypto conference on May 8, 2026 and expressed the political will for a coordinated approach. Second, Côte d'Ivoire is the largest UEMOA economy — a pilot there multiplies to 8 countries and 130 million people. Third, BCEAO Instruction 2023 already creates the legal basis for VASP data sharing. The infrastructure for the pilot already partially exists."
"Who funds this? How do we get the money?"
"ATAF already receives funding from bilateral donors: NORAD (Norway), GIZ (Germany), SIDA (Sweden), and the IMF Capacity Development Office. A Phase 1 concept note submitted to the ATAF Research Advisory Committee can access these funds through existing project pipelines. The World Bank ICTD (International Centre for Tax and Development) also specifically funds African digital tax infrastructure projects. The total Phase 1 budget is $70,000–$150,000 — a standard technical assistance grant, not a major procurement."
"What is your role — are you an employee, a contractor, a researcher?"
"I am a Fiscal Economist and BI Developer currently conducting this research under the supervision of Professor Gitte Heij at the University of Melbourne. My proposal to ATAF is a consulting engagement — I deliver Phase 1 as a contracted technical expert, with full knowledge transfer to ATAF staff and open-source publication of all code. ATAF retains full ownership of the infrastructure. I provide the technical expertise and the prototype already demonstrates the concept works."

CONCEPT NOTE
Digital Crypto Tax Intelligence System for Africa
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Submitted to: ATAF Technical Committee
Author: Anthelme N'DRI
Fiscal Economist · BI Developer · IT Expert · Researcher

Supervisor: Prof. Gitte Heij · University of Melbourne, Australia
Date: [Date of submission]
Prototype: https://ndriresearchlab.ddns.net/crypto_conference/
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
1. THE PROBLEM
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
$117 billion in crypto transactions across Sub-Saharan Africa
annually (Chainalysis, 2022). Only 5 of 54 African countries
have a functional crypto tax framework. Effective collection
rate: approximately 0%.
The OECD CARF framework — the global standard — requires
licensed exchanges, universal TINs, XML processing
infrastructure, and bilateral agreements that most African
DGIs do not yet have. CARF implementation timeline: 3–5 years.
The problem is not political will. The BCEAO International
Conference (Dakar, May 8, 2026) confirmed that 6 central bank
governors are aligned on the need for a coordinated approach.
The problem is the absence of a technically adapted framework
for African administrative capacity.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
2. PROPOSED SOLUTION
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
A modular, open-source Fiat-Crypto Tax Intelligence System
comprising five modules:
Module 1 — Fiat-Crypto Link Engine
Reconstructs the complete fiat → crypto → fiat cycle by
connecting mobile money entry points (Wave, Orange Money,
MTN MoMo), exchange KYC data, blockchain transaction records,
and bank cash-out points. Identifies taxable events at
conversion points — not through full blockchain monitoring.
Module 2 — Blockchain Analytics Layer
Wallet clustering, VASP identification, hop tracing across
1–3 transaction hops. Uses free public APIs (Etherscan,
Blockchair, Covalent). No Chainalysis subscription required.
Module 3 — Tax Event Classifier
Automatically classifies transactions: Capital Gain, Income,
WHT applicable, P2P gap. Based on ATAF Technical Note
principles and Indonesia WHT model (April 2022).
Module 4 — Risk Scoring Engine
Scores each identified taxpayer 0–100 based on volume,
transaction pattern, P2P ratio, KYC status, and compliance
history. Prioritizes audit allocation.
Module 5 — Fiscal Dashboard
Administration interface for tax officers. Audit queue,
revenue tracking, VASP data request automation, export.
Core principle:
"Tax administration in the crypto era is about controlling
value transitions, not monitoring every transaction."
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
3. WORKING PROTOTYPE
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
A fully functional demo is available at:
https://ndriresearchlab.ddns.net/crypto_conference/
The prototype includes:
— Blockchain Tracer (Chainalysis-style transaction tracing)
— Fiat-Crypto Link Engine (all 5 modules operational)
— 10 interactive tools for tax administrators
— Binance Africa case study (real transaction reconstruction)

Mobile money data (Wave, Orange Money): Requires a bilateral agreement between the DGI and the telecom operator. This is legally possible — BCEAO Instruction 2023 creates the framework. In practice, the DGI needs to formally request data sharing with Wave/Orange via the Ministry of Finance. This is a political/institutional step, not a technical one. Start Phase 1 without it (blockchain data only) and add mobile money in Phase 2.
