EchoForge 🔐

Zero-leakage, biometric-secured portfolio tracker: Live data, local encryption, and cross-device FIDO2 authentication for finance and crypto.

Your wealth data never leaves your device. No cloud storage. No data brokers. No surveillance capitalism. Just pure, cryptographic-grade privacy with real-time portfolio insights.

---

🎯 Why EchoForge?

Stop feeding your financial data to surveillance platforms. Mint, Personal Capital, and others monetize your transaction history. EchoForge takes a different approach: zero-knowledge architecture where even we can't see your data.

The Problem

• 🚨 Traditional portfolio trackers sell your data to advertisers
• 🔓 Cloud storage = attack surface for hackers
• 📊 Manual tracking = outdated, error-prone portfolios
• 🔑 Password authentication = phishing vulnerability

The Solution

✅ Local-First Architecture: All data encrypted client-side using AES-256-GCM
✅ FIDO2 Biometric Auth: Fingerprint/Face ID replaces vulnerable passwords
✅ Real-Time Intelligence: Live price feeds with zero API key exposure
✅ Multi-Asset Support: Stocks, crypto, commodities, real estate, NFTs
✅ Set-and-Forget Automation: Runs offline with automated security scanning

🛡️ Security Architecture

EchoForge implements defense-in-depth with three independent security layers:

┌─────────────────────────────────────────────────────────────┐
│  LAYER 1: FIDO2 Biometric Authentication                    │
│  • WebAuthn standard (W3C)                                   │
│  • Device-bound cryptographic keys                           │
│  • Phishing-resistant by design                              │
└─────────────────────────────────────────────────────────────┘
                            ↓
┌─────────────────────────────────────────────────────────────┐
│  LAYER 2: Client-Side Encryption                            │
│  • AES-256-GCM (NIST approved)                               │
│  • PBKDF2 key derivation (600k iterations)                   │

└─────────────────────────────────────────────────────────────┘
                            ↓
┌─────────────────────────────────────────────────────────────┐
│  LAYER 3: Offline Storage                                    │
│  • IndexedDB (sandboxed browser storage)                     │
│  • No network transmission of sensitive data                 │
│  • Optional encrypted backups (user-controlled)              │
└─────────────────────────────────────────────────────────────┘

Threat Mitigation

✅ Server Breach: Impossible - we don't store your data
✅ Man-in-the-Middle: Client-side encryption renders intercepts useless
✅ Phishing: FIDO2 is origin-bound and phishing-resistant
✅ Brute Force: 600k PBKDF2 iterations + rate limiting
✅ Supply Chain Attack: Open source + automated security scanning
✅ Insider Threat: Zero-knowledge architecture = zero access

📈 RM²E Crypto Momentum Tracking

EchoForge includes a production-grade RM²E (Risk-Momentum-Magic-Effort) scoring algorithm for cryptocurrency momentum tracking. This system helps identify explosive opportunities while managing risk through volatility-adjusted scoring.

RM²E Threshold Reference

Use these calibrated thresholds to interpret RM²E scores:

• < 50: Stagnant (avoid)
• 50-100: Normal momentum (HOLD)
• 100-150: Heating up (BUY)
• 150+: Explosive (STRONG BUY)
• > 300: Parabolic (take profits)

Expected Score Ranges

The enhanced algorithm produces differentiated scores based on market conditions:

• Bitcoin (low volatility, high cap): typically 80-120
• Ethereum (medium volatility): typically 100-150
• Solana (high volatility, lower cap): typically 150-300

Formula Breakdown

RM²E = (momentum × magic) / (risk × effort) × 100

Where:
- Risk: Volatility-adjusted (24h + 7d weighted standard deviation)
- Momentum: Recent change weighted (70% 24h, 30% 7d)
- Magic: Progressive multiplier (1x to 20x based on uptrend strength)
- Effort: Liquidity penalty (inverse log of market cap)

Component Details:

1. Risk Calculation: Math.sqrt(Math.pow(change24h, 2) + Math.pow(change7d / 7, 2)) / 10

   • Volatility-based formula with 0.1 floor to prevent division by zero

2. Momentum Scoring: change24h * 0.7 + change7d * 0.3

   • Weights recent changes higher
   • Only positive momentum counts (negatives filtered to 0)

3. Magic Multiplier:

   • change24h > 10%: magic = 20
   • change24h > 5%: magic = 15
   • change24h > 0%: magic = 10
   • Otherwise: magic = 1

4. Effort Calculation: Math.max(1, 100 / Math.log10(usd_market_cap + 10))

   • Larger market cap = easier entry = lower effort penalty

API Rate Limits

The system implements exponential backoff to respect CoinGecko API limits:

• CoinGecko free tier: 50 calls/min
• Current polling: 24 calls/min (2.5s intervals)
• Safe margin: Automatic backoff on 429 errors
• Max retry delay: 60 seconds

Rate limit protection doubles the delay on each 429 error (up to 60s max), then resets to 2.5s on successful fetch.

Usage Example

import CryptoSparks from '../components/CryptoSparks';

export default function Dashboard() {
  return (
    <div>
      <h1>Portfolio Dashboard</h1>
      <CryptoSparks 
        symbols={['bitcoin', 'ethereum', 'solana']}
        pollingInterval={2500}
      />
    </div>
  );
}
