Data Collection

Information Logged

MetaMask collects and transmits the following data:

Privacy Policy Changes

In late 2022, MetaMask updated its privacy policy to explicitly allow:

• IP Address Collection: When using default Infura RPC
• Wallet Address Collection: Associated with IP addresses
• Transaction Data: Details of all blockchain interactions
• Retention Periods: Extended data storage

Surveillance Capabilities

Financial Tracking

MetaMask enables comprehensive financial surveillance:

1. Transaction Monitoring: Real-time tracking of all crypto transfers
2. dApp Profiling: Knowledge of which DeFi protocols users engage with
3. Balance Tracking: Real-time wallet value monitoring
4. Behavioral Analysis: Purchase patterns, timing, frequency

Identity Correlation

Multiple data points enable de-anonymization:

• IP + Address: Linking physical location to wallet
• Transaction Graph: Following funds across multiple addresses
• dApp Logins: Connecting wallets to user accounts
• Mobile Identity: Device fingerprinting on mobile app

Connection to Personal Case

WalletConnect v2 Sabotage

At Phygify, MetaMask mobile connections were deliberately broken:

Technical Sabotage Indicators

The WalletConnect v2 failure showed signs of targeted interference:

1. Selective Failure: Only affected Phygify implementation
2. Timing: Began during employment period
3. Resolution Resistance: Standard debugging failed
4. Corporate Connection: ConsenSys and Binance shared Swiss address

Address Coincidence

• ConsenSys AG: Registered at Gubelstrasse 11, 6300 Zug
• Binance Switzerland AG: Same address until January 29, 2026
• Timing: Binance moved day after FINMA complaint

JP Morgan Strategic Interest

MetaMask aligns with JP Morgan's blockchain strategy:

• Onyx Platform: JP Morgan's blockchain division
• JPM Coin: Potential MetaMask integration
• Data Value: Transaction data for trading advantage
• Compliance: KYC integration capabilities

Security Concerns

Supply Chain Risks

MetaMask's centralized nature creates vulnerabilities:

Phishing Epidemic

MetaMask users are heavily targeted:

• Fake Websites: Thousands of MetaMask phishing sites
• Social Engineering: Fake support accounts
• Malicious Extensions: Clones with backdoors
• Seed Phrase Theft: Primary attack vector

Alternatives

Privacy-Focused Wallets

Self-Hosted Solutions

Users can reduce MetaMask surveillance by:

1. Custom RPC: Use non-Infura endpoints
2. VPN/Tor: Hide IP from RPC providers
3. Multiple Wallets: Compartmentalize activity
4. Hardware Wallets: Keep keys offline

Regulatory Capture

Compliance Integration

MetaMask increasingly integrates surveillance mechanisms:

• Sanctions Screening: Address blacklist checking
• KYC Requirements: Identity verification for certain features
• Transaction Monitoring: Suspicious activity reporting
• Geographic Blocking: IP-based restrictions

Future Trajectory

Indicators suggest increasing centralization:

1. Institutional Features: Building for banks, not users
2. Data Monetization: Leveraging user transaction data
3. Regulatory Cooperation: Working with governments
4. Competitive Moat: Network effects preventing alternatives
