SIP Privacy Mobile Wallet

Privacy is not a feature. It's a right.

The first privacy-native Solana wallet — stealth addresses + viewing keys for iOS, Android & Seeker

One toggle to shield • Native key management • Compliant privacy • Jupiter DEX integration

🛡️ What is SIP Privacy?

SIP Privacy is a standalone privacy wallet for Solana — not a layer on top of other wallets. Create or import your wallet directly, then send shielded payments with stealth addresses and Pedersen commitments.

Traditional Wallet  → Public transactions (everyone sees everything)
SIP Privacy Wallet  → Shielded transactions (you control who sees what)

Stop exposing your financial activity. Start transacting privately.

The Privacy Upgrade

❌ Traditional Wallet ✅ SIP Privacy Wallet

Send 10 SOL to alice.sol

Public record:
• Your address: 7xK9...
• Amount: 10 SOL
• Recipient: alice.sol
• Forever on-chain

Everyone sees:

🔴 Your wallet address
🔴 Exact amounts
🔴 Recipient identity
🔴 Full transaction history

Send 10 SOL to alice.sol
(Privacy: Shielded)

On-chain record:
• Stealth address: 9aB3...
• Commitment: 0xdef...
• No link to alice.sol

Protected:

✅ Sender hidden
✅ Amount hidden (commitment)
✅ Recipient hidden (stealth)
✅ Unlinkable transactions

🎯 The Problem

Mobile wallets expose everything about your transactions. This isn't just inconvenient — it's a surveillance system.

What's Exposed on Solana

Data Point	Visibility	Risk
Your Address	Public	Targeted phishing, social engineering
Token Balances	Public	Wealth profiling, price discrimination
Transaction History	Permanent	Financial surveillance, address clustering
Recipient Addresses	Public	Social graph analysis, relationship mapping

Real Consequences

Targeted attacks — High-value wallets get phished
MEV extraction — Bots front-run your swaps
Price discrimination — Services charge based on your balance
Surveillance — Governments/exchanges track all activity

💡 The Solution

SIP Privacy wraps Solana transactions in a cryptographic privacy layer using battle-tested technology.

Core Privacy Mechanisms

Mechanism	Purpose	How It Works
Stealth Addresses	Hide recipients	Fresh one-time address per transaction
Pedersen Commitments	Hide amounts	`value * G + blinding * H`
Viewing Keys	Selective disclosure	Share read-only access with auditors
Privacy Levels	User control	Transparent, Shielded, or Compliant

✨ Key Features

🔐 Native Wallet

Create or import your wallet directly — no dependency on external wallets. Your keys, your crypto.

🛡️ Three Privacy Levels

Level	Description	Use Case
`Transparent`	Standard public transaction	When privacy isn't needed
`Shielded`	Full privacy (stealth + commitment)	Personal transactions
`Compliant`	Privacy + viewing key	Institutional/tax compliance

👻 Stealth Addresses

Every payment uses a fresh one-time address. No address reuse, no transaction linkability.

🔑 Viewing Keys

Share read-only access with auditors or tax authorities without exposing your spending keys.

💱 Jupiter DEX Integration

Swap any Solana token with privacy toggle. Best routes + privacy protection.

📱 Multi-Platform

iOS — App Store ready
Android — Google Play + direct APK
Seeker — Solana dApp Store (native Seed Vault integration)

🔒 Secure Storage

Keys protected with SecureStore + biometric authentication (Face ID / fingerprint).

📦 Installation

Download APK (Android/Seeker)

Download APK v0.1.6 →

Build from Source

# Clone the repository
git clone https://github.com/sip-protocol/sip-mobile.git
cd sip-mobile

# Install dependencies
pnpm install

# Start development server
npx expo start

🚀 Quick Start

1. Create or Import Wallet

Create new wallet    →  BIP39 mnemonic (12/24 words)
Import seed phrase   →  Standard Solana derivation (m/44'/501'/0'/0')
Import private key   →  Base58 encoded

2. Fund Your Wallet

Send SOL to your wallet address. Works on both devnet and mainnet.

3. Send Private Payment

Go to Send tab
Enter recipient address or scan QR
Enter amount
Select Privacy Level: Transparent, Shielded, or Compliant
Confirm and send

4. Receive Private Payment

Go to Receive tab
Share your Stealth Meta-Address (not your public key)
Sender uses SIP to generate one-time stealth address
Scan to detect incoming payments

5. Export Viewing Key (Optional)

For auditors/compliance:

Go to Settings → Viewing Keys
Export viewing key for specific time range
Share with auditor (they can see but not spend)

🔐 Security

Threat Model

Threat	Mitigation
Key extraction	SecureStore encryption + biometrics
Transaction replay	Unique stealth addresses per tx
Amount correlation	Pedersen commitments hide values
Network analysis	Stealth addresses break linkability

Security Best Practices

✅ Keys never leave the device (except explicit export)
✅ Biometric authentication for sensitive operations
✅ No analytics or tracking in production
✅ Open source for audit
❌ Never share your seed phrase
❌ Never screenshot your keys
