ENGINEERING FINANCIAL INCLUSION

Six interconnected layers powering decentralized remittance-to-credit infrastructure. From webhook ingestion to on-chain settlement, every component is built for scale, transparency, and resilience.

SYSTEM ARCHITECTURE

Each layer operates independently with well-defined interfaces, enabling modular upgrades, isolated testing, and composable integration with the broader Creditcoin ecosystem.

Integration Layer

Remittance Verification Engine

Webhook-based pipeline that captures, validates, and normalizes incoming remittance data from 78+ Money Transfer Operators in real-time. Supports REST, GraphQL, and event-streaming protocols with automatic retry and dead-letter queuing.

Sub-200ms webhook processing

99.99% uptime SLA

Multi-MTO normalization

Automatic fraud detection

Intelligence Layer

AI-Driven LTV Scoring

Ensemble ML models combining XGBoost gradient boosting, LSTM temporal analysis, and transformer-based corridor risk assessment. Trained on 500K+ anonymized remittance patterns with continuous online learning from live transaction data.

94% repayment prediction accuracy

Real-time model inference (<50ms)

Explainable AI audit trails

Multi-corridor risk calibration

Smart Contract Layer

Vault Abstraction Protocol

Audited Solidity contracts deployed on Creditcoin implementing multi-signature vault management, programmable withdrawal controls, and automated credit issuance logic. All state transitions are verifiable on-chain.

Formal verification completed

Multi-sig governance

Programmable withdrawal rules

Gas-optimized execution

Oracle Layer

Chainlink Price Feed Integration

Decentralized price oracles providing real-time forex rates for 78+ remittance corridors, asset volatility indices, and corridor-specific risk premiums. Heartbeat updates every 60 seconds with deviation thresholds.

78+ currency pairs supported

60-second heartbeat updates

Deviation-triggered refreshes

Multi-source aggregation

Monitoring Layer

Real-Time Analytics Pipeline

Event-driven data streaming architecture providing live dashboards for credit positions, vault health, corridor performance, and system-wide risk metrics. Powers both user-facing interfaces and internal risk management.

Sub-second data propagation

Historical analytics & export

Anomaly detection alerts

Custom metric dashboards

Security Layer

Zero-Knowledge Compliance

Privacy-preserving identity verification and KYC/AML compliance using zero-knowledge proofs. Recipients prove creditworthiness without exposing sensitive personal data to on-chain validators.

ZK-proof identity verification

GDPR-compliant data handling

On-chain audit trails

Multi-jurisdiction compliance
