FEHUVIA.

EXECUTIVE SUMMARY

Open-finance Web3 B2B treasury workstation for Southeast Asian SMEs, marrying relational database state tracking with smart-contract execution rails on Morph L2 to cut settlement from a 3-day banking standard to under 2 seconds (T+0), at a fraction of a cent per transaction.

SYSTEM HIGHLIGHTS

• Atomic sub-2-second payment clearance on Morph L2 via custom Solidity contracts
• EVM listener daemon: real-time log syncing into PostgreSQL for dual-state financial auditing
• AI financial co-pilot: GPT-4o RAG pipeline for structured cashflow analytics and runway forecasting
• AI OCR scan auto-parses uploaded invoice sheets and fills workstation drawers
• Self-healing background gas faucet dispenses L2 gas asynchronously to MetaMask operators
• Zero-custody: client-side signing via MetaMask (EIP-1193): no private keys near the server

CORE ARCHITECTURE

• B2BSettlement.sol: mUSDC ERC-20 clearance mapped to invoice UUIDs, strict checks-effects-interactions, PaymentSettled event telemetry
• Express backend orchestrates AI pipelines and PostgreSQL persistence (pg-pool)
• Listener daemon reconciles on-chain events into the relational ledger (dual-state)
• Faucet: < 0.005 ETH balance trigger → 0.002 ETH async dispense from a vault key
• GPT-4o context-aware RAG prompting with runway JSON structuring
