Private Transactions
Learn how Darkwhale enables completely anonymous transactions on Solana.
What Are Private Transactions?
Private transactions on Deepblue hide:
🔒 Sender wallet address
🔒 Receiver wallet address
🔒 Transaction amount
🔒 Transaction metadata
While still being:
✅ Verified on blockchain
✅ Cryptographically secure
✅ Fast (< 5 seconds)
✅ Low cost (0.0001 SOL fee)
How It Works
Treasury Privacy Model
Deepblue uses a dual-transaction privacy layer:
You → Treasury Wallet → Recipient
(TX 1) (TX 2)Transaction 1: User → Treasury
You send: Amount + 0.0001 SOL fee
Destination: Deepblue Treasury
On blockchain: Your address → Treasury address
Signature saved: Your TX ID
Transaction 2: Treasury → Recipient
Treasury sends: Exact amount (no fee deduction)
Destination: Recipient's wallet
On blockchain: Treasury address → Recipient address
Signature saved: Privacy TX ID
Privacy Result:
No direct link between you and recipient
Multiple users share same treasury
Mixing effect obscures connections
Complete transaction history recorded
Zero-Knowledge Proofs
Optional ZK proof generation:
What It Proves: ✅ You have sufficient balance ✅ Transaction is valid ✅ Signatures are correct ✅ No double-spending
What It Hides: ❌ Your actual balance ❌ Transaction details ❌ Wallet history ❌ Other transactions
Generation:
Takes 2-3 seconds
Done locally on your device
Creates ~200 byte proof
Optional but recommended

Privacy Analysis
What Blockchain Shows
Transaction 1 (Public):
Transaction 2 (Public):
Observer Sees:
Two separate transactions
Different timestamps
Treasury as intermediary
Multiple users using treasury
Observer CANNOT See: ❌ Connection between TX 1 and TX 2 ❌ Your link to recipient ❌ Your total transaction volume ❌ Your transaction patterns
Anonymity Set
Set Size:
All users using Deepblue treasury
Typically 100-1000+ concurrent users
Larger set = better privacy
Constantly growing
Effect:
Your transaction mixes with others
No way to distinguish
Statistical anonymity
Plausible deniability

Best Practices
For Maximum Privacy
1. Use Different Wallets
2. Vary Transaction Patterns
Don't send same amounts
Randomize timing
Mix with regular TXs
Use delays
3. Enable ZK Proofs
For sensitive transactions
For large amounts
For long-term privacy
For pattern protection
4. Operational Security
Use VPN
Private browsing
Clear cache
Don't discuss transactions
Common Mistakes to Avoid
❌ DON'T:
Link wallets publicly (social media)
Reuse addresses
Send round amounts (0.1, 1.0, etc.)
Make regular scheduled transfers
Screenshot transactions
✅ DO:
Use fresh addresses
Vary amounts (0.0734, 1.2456, etc.)
Random timing
Keep transactions private
Use encrypted notes only
