+
+### Bitcoin Wallet Privacy Analyzer
+
+A privacy audit tool that surfaces vulnerabilities at the UTXO level.
+
+---
+
+# The Problem
+
+<div class="grid grid-cols-2 gap-8">
+
+<div>
+
+**Bitcoin privacy is fragile**
+
+- Chain analysis firms track wallets
+- Common heuristics link addresses
+- Users rarely know their exposure
+- One bad UTXO can taint the rest
+
+</div>
+
+<div>
+
+**Today's tools**
+
+- Complex, require expertise
+- No UTXO-level visibility
+- Hard to understand risk before spending
+
+</div>
+
+</div>
+
+---
+
+# What Stealth Does
+
+<div class="grid grid-cols-2 gap-6">
+
+<div>
+
+**Input**
+- Paste wallet descriptor
+- Supports `wpkh`, `pkh`, `sh(wpkh)`, `tr`, multisig
+
+**Output**
+- Every UTXO listed
+- Privacy flaws per UTXO
+- Severity badges (high / medium / low)
+
+</div>
+
+<div>
+
+```bash
+# One click
+wpkh([xpub...]/0/*) → Analyze
+```
+
+→ Full report with actionable insights
+
+</div>
+
+</div>
+
+---
+
+# Vulnerabilities Detected
+
+| Vulnerability | What it means |
+|---------------|---------------|
+| **Address Reuse** | Same address received >1 payment — links tx history, exposes balance |
+| **Dust Spend** | UTXO from dust attack — when spent, links previously unconnected addresses |
+| **UTXO Consolidation** | Multiple inputs merged — strong signal all belong to same wallet |
+| **CIOH** | Common Input Ownership Heuristic — chain analysis firms use this to cluster addresses |
+
+---
+
+# How It Works
+
+<div class="grid grid-cols-3 gap-4">
+
+<div class="card p-4">
+
+**1. Parse**
+- Extract addresses from descriptor
+- Support all common formats
+
+</div>
+
+<div class="card p-4">
+
+**2. Fetch**
+- On-chain history per address
+- Uses Bitcoin node / API
+
+</div>
+
+<div class="card p-4">
+
+**3. Analyze**
+- Apply privacy heuristics
+- Flag each UTXO with findings
+
+</div>
+
+</div>
+
+---
+
+# Architecture
+
+```
+stealth/
+├── frontend/   # React + Vite — input, loading, report
+└── backend/    # Java/Quarkus — descriptor parsing, chain data, analysis
+```
+
+- **Read-only** — no keys, no storage, no transmission of descriptors
+- **Self-hostable** — point at your own node for max privacy
+
+---
+
+# Demo Flow
+
+1. **Input screen** — paste descriptor, click Analyze
+2. **Loading** — fetches and analyzes
+3. **Report** — summary bar (total / vulnerable / clean) + UTXO cards
+4. Each card: address, amount, badges, expandable details
+
+---
+
+# Why It Matters
+
+- **Users** — understand exposure before consolidating or spending
+- **Wallets** — integrate as pre-spend check
+- **Researchers** — study privacy heuristics at scale
+- **Privacy-first** — no cloud, no logs, no tracking
+
+---
+
+# Thank You

+
+# Appendix — Supported Descriptors
+
+- `wpkh(...)` — native SegWit
+- `pkh(...)` — legacy
+- `sh(wpkh(...))` — nested SegWit
+- `tr(...)` — Taproot
+- Multisig variants
+
+All analysis uses publicly available on-chain data.
