🏛ī¸ Regulatory Security Notice & Custody Framework

Fimpaypoint (operated by Fim Digital Ventures Limited) is a financial technology software provider, not a bank. We deliver application-layer cryptography, real-time fraud defense, and payment orchestration software. Banking rails, dedicated virtual account numbers, and cash settlements are provided in technical partnership with Central Bank of Nigeria (CBN) licensed commercial banks, microfinance banks, and licensed payment switching institutions. All merchant and customer funds reside in segregated custodial trust accounts with NDIC-insured financial institutions.

1. Transport & Network Perimeter Defense

Every connection to Fimpaypoint is protected with enterprise-grade transport encryption and strict security policies. Cleartext traffic is rejected at the edge.

Our edge infrastructure utilizes enterprise Web Application Firewalls (WAF), volumetric DDoS mitigation, bot inspection shields, and rate-limiting heuristics designed to block automated brute-force attacks and credential stuffing.

2. Cryptographic Standards & Data Protection

Sensitive records, settlement bank account details, verification hashes, and authentication secrets are protected using industry-standard authenticated encryption:

  • One-Way Credential Hashing: User and merchant passwords and authentication secrets are never stored in plaintext. All credentials are protected using irreversible cryptographic one-way hashing.
  • Cryptographic Key Management: API keys and webhook secrets are cryptographically generated and can be rotated instantly from the merchant dashboard.

3. Automated Financial Reconciliation Engine

To ensure zero-loss accounting and eliminate mathematical discrepancies, the Fimpaypoint core system operates on strict transaction reconciliation principles.

Every inbound collection, payout, fee deduction, and tax levy generates verified immutable transaction records. Account balances are calculated dynamically from verified events, rendering balance tampering impossible.

4. API Security & Signed Webhooks

Developer integrations interact with our REST API over authenticated, scoped bearer tokens with enforced role-based permissions:

  • HMAC SHA-256 Signatures: Every outbound webhook notification contains an X-FimPay-Signature header generated from the merchant's secret key, enabling instantaneous authenticity verification.
  • IP Whitelisting: High-volume merchants can enforce IP restriction policies on their API credentials, rejecting requests originating from unrecognized IP addresses.
  • Idempotency Guarantees: Inbound payment link and transfer creation endpoints enforce unique reference keys, preventing duplicate charges from network retries.

5. Authentication, 2FA & Biometric Passkeys

Account access and high-risk actions (such as manual payouts, API key reveals, and settlement bank changes) are protected by mandatory multi-factor authentication:

🔐 Time-based OTP (2FA)

Standard RFC 6238 TOTP authenticator app support (Google Authenticator, Authy, 1Password) for sign-in verification.

👆 FIDO2 / WebAuthn Biometrics

Hardware-backed biometric passkeys (TouchID, FaceID, Windows Hello, YubiKey) providing phishing-resistant login.

6. Vulnerability Disclosure & Security.txt

Fimpaypoint adheres to RFC 9116 (A File Format to Aid in Security Vulnerability Disclosure). Ethical security researchers can inspect our security parameters at /.well-known/security.txt .

We operate a responsible disclosure safe-harbor program. Researchers who discover vulnerabilities in good faith are encouraged to report them immediately to our Infosec team without fear of legal action.
