Tether QVAC Integration

Qguard

Air-gapped wallet intelligence — LLM, RAG, OCR, and voice queries with zero network calls.

● NETWORK: OFFLINE

Colosseum Frontier Hackathon 2026

The Problem

Your wallet data leaves your device the moment you check it.

  • 🌐 Cloud dependency — Every portfolio tracker sends your holdings to remote servers
  • 🎯 Targeted attacks — Leaked balances make you a phishing/SIM-swap target
  • 📋 No local analysis — No way to query transactions, verify contracts, or OCR receipts offline

The Solution

Four QVAC features. All running locally. Zero outbound API calls.

🧠

Local LLM

On-device AI analyzes wallet risk in <2s.

📚

Security RAG

Query scam/exploit DB: "Is 0x... safe?"

📸

Receipt OCR

Photo → amount → matched to on-chain tx.

🎤

Voice Query

"Show txs over $1K last week" → filtered.
