Nigerian Crypto Platform Compliance — VASP, Blockchain Analytics and Custody Architecture

#nigeria #cryptocurrency #blockchain

Building a Nigerian crypto exchange is a software problem. Operating one legally requires compliance architecture that most Nigerian crypto codebases don't have. Here is the technical implementation.

1. Blockchain Analytics — Screen Every Deposit

// Every incoming crypto deposit must be screened BEFORE crediting
// Integrate with Chainalysis, Elliptic or TRM Labs

async function screenIncomingDeposit(txHash, network, userId) {
  const screening = await chainalysis.screenTransaction({ txHash, network });

  const criticalRisks = [
    'sanctions', 'darknet_market', 'mixer',
    'ransomware', 'stolen_funds', 'terrorist_financing'
  ];

  const hasCriticalRisk = screening.categories.some(
    c => criticalRisks.includes(c.name) && c.percentage > 10
  );

  if (hasCriticalRisk || screening.riskScore >= 70) {
    await rejectDeposit(txHash, userId);
    await fileBlockchainSAR(txHash, userId, screening);
    return { approved: false, action: 'REJECTED' };
  }

  if (screening.riskScore >= 40) {
    await holdForManualReview(txHash, userId, screening);
    return { approved: false, action: 'MANUAL_REVIEW' };
  }

  await approveDeposit(txHash, userId);
  return { approved: true, action: 'APPROVED', riskScore: screening.riskScore };
}

2. Travel Rule — Required Above Threshold

// Transfers above $1,000 equivalent require Travel Rule compliance
// Originating VASP must transmit sender/recipient info to receiving VASP

async function sendTravelRuleInfo(transfer) {
  const amountUSD = await convertToUSD(transfer.amount, transfer.asset);
  if (amountUSD < 1000) return { required: false };

  await travelRuleProtocol.send({
    to: await identifyReceivingVASP(transfer.destinationAddress),
    originator: {
      name: transfer.sender.fullName,
      nationalId: transfer.sender.idType + ':' + transfer.sender.idHash,
      vasp: { name: 'ZikarelHub Exchange', jurisdiction: 'NG' }
    },
    beneficiary: {
      accountId: transfer.destinationAddress
    },
    transfer: {
      amount: transfer.amount,
      asset: transfer.asset,
      txHash: transfer.txHash
    }
  });

  return { required: true, sent: true };
}

3. Custody Compliance

// Maintain 95%+ cold storage — check daily
async function assessCustodyCompliance() {
  const total = await getTotalClientAssets();
  const hot = await getHotWalletBalance();
  const hotRatio = hot / total;

  if (hotRatio > 0.05) {
    await alertCustodyTeam({
      severity: 'HIGH',
      message: `Hot wallet at ${(hotRatio * 100).toFixed(1)}% — move to cold storage`,
      target: '< 5%'
    });
  }

  return { compliant: hotRatio <= 0.05, hotRatio };
}

// Proof of reserves — cryptographic demonstration of full backing
async function generateProofOfReserves() {
  const userBalancesTotal = await sumAllUserBalances();
  const platformHoldings = await verifyOnchainHoldings();

  return {
    fullyBacked: platformHoldings >= userBalancesTotal,
    reserveRatio: platformHoldings / userBalancesTotal,
    merkleRoot: buildMerkleTree(await getAllUserBalances()).root,
    timestamp: new Date().toISOString()
  };
}

4. VASP Registration Checklist

Before operating any Nigerian crypto service:

- [ ] CAC registration as Nigerian company
- [ ] VASP registration filed with SEC Nigeria
- [ ] OR enrolled in VASP Incubation Programme
- [ ] Minimum capital requirements met
- [ ] AML/CFT policy documented and signed
- [ ] Custody policy documented
- [ ] Consumer protection framework documented
- [ ] Technology security assessment completed
- [ ] Incident response plan documented

The Compliance Gap

// Most Nigerian crypto platforms:
const typicalGaps = [
  'No VASP registration with SEC Nigeria',
  'No blockchain analytics — deposits not screened',
  'No Travel Rule — info not transmitted on large transfers',
  'Hot wallet > 5% of client assets',
  'Client and operational assets commingled',
  'No proof of reserves capability',
  'Inadequate risk disclosure to users'
];

// All addressable. None optional.
