+# PrivacyLayer FAQ
+
+Frequently Asked Questions about PrivacyLayer, privacy, and zero-knowledge proofs.
+
+---
+
+## General Questions
+
+### What is PrivacyLayer?
+
+PrivacyLayer is a privacy protocol built on the Stellar blockchain that enables users to make private transactions using zero-knowledge proofs. It allows you to deposit funds into a privacy pool and withdraw them to a fresh address, breaking the link between your deposit and withdrawal.
+
+### How is PrivacyLayer different from other privacy solutions?
+
+| Feature | PrivacyLayer | Tornado Cash | Monero |
+|---------|--------------|--------------|--------|
+| Blockchain | Stellar | Ethereum | Native |
+| Privacy Method | ZK Proofs | ZK Proofs | Ring Signatures |
+| Smart Contracts | Soroban | Solidity | None |
+| KYC Compatible | Yes | Limited | No |
+| Transaction Speed | ~5 seconds | ~15 seconds | ~2 minutes |
+
+### Is PrivacyLayer legal?
+
+PrivacyLayer is designed with regulatory compliance in mind. The protocol itself is neutral technology. Users are responsible for complying with their local regulations. PrivacyLayer includes features for compliance where appropriate.
+
+### What cryptocurrencies are supported?
+
+PrivacyLayer currently supports:
+- XLM (Stellar Lumens)
+- USDC on Stellar
+- Additional assets as the ecosystem grows
+
+---
+
+## Technical Questions
+
+### How do zero-knowledge proofs protect my privacy?
+
+Zero-knowledge proofs allow you to prove you have the right to withdraw funds without revealing which deposit you're withdrawing from. This is achieved through:
+
+1. **Commitments:** Your deposit creates a cryptographic commitment that goes into a Merkle tree
+2. **Nullifiers:** Each withdrawal uses a unique nullifier that prevents double-spending without revealing the source
+3. **ZK Proofs:** The proof verifies you know the preimage of a commitment in the tree without revealing which one
+
+### What is the minimum deposit amount?
+
+The minimum deposit amount varies by asset and is designed to prevent dust attacks. Check the dApp for current minimums.
+
+### How long should I wait before withdrawing?
+
+For optimal privacy, wait until there have been several deposits after yours. A general rule:
+- **Minimum:** Wait for 5+ deposits after yours
+- **Recommended:** Wait for 20+ deposits
+- **High Privacy:** Wait for 100+ deposits
+
+### What are the fees?
+
+Fees include:
+- **Network fees:** Standard Stellar transaction fees (~0.00001 XLM)
+- **Protocol fee:** A small percentage to maintain the protocol
+- **Relayer fee:** If using a relayer for gasless transactions
+
+Exact fees are displayed before each transaction.
+
+### Can I track my deposit?
+
+Yes, you can track your deposit using the note/private key generated when you deposited. **Keep this safe** - it's the only way to withdraw your funds.
+
+---
+
+## Security Questions
+
+### What happens if I lose my deposit note?
+
+**Your funds will be permanently lost.** The deposit note contains the private key needed to generate the withdrawal proof. There is no way to recover lost notes.
+
+**Best practices:**
+- Write down your note on paper
+- Store multiple copies in secure locations
+- Never share your note with anyone
+- Consider using a hardware wallet for additional security
+
+### Is PrivacyLayer audited?
+
+Yes, PrivacyLayer undergoes regular security audits by reputable firms. Audit reports are available in the repository. Key audits include:
+
+- Smart contract audits
+- ZK circuit audits
+- Infrastructure security reviews
+
+### What are the risks?
+
+1. **Smart Contract Risk:** Bugs in contracts could lead to loss of funds
+2. **Circuit Risk:** Flaws in ZK circuits could compromise privacy
+3. **User Error:** Losing notes or poor operational security
+4. **Regulatory Risk:** Changes in regulations could affect usage
+
+### How do I report a vulnerability?
+
+Please report vulnerabilities through our Bug Bounty Program. See `docs/BUG_BOUNTY_PROGRAM.md` for details. Responsible disclosure is rewarded.
+
+---
+
+## Privacy Questions
+
+### How private are my transactions?
+
+PrivacyLayer provides strong privacy guarantees when used correctly:
+
+**Protected:**
+- Transaction amounts
+- Source addresses
+- Destination addresses
+- Transaction timing (when used properly)
+
+**Potentially Linkable:**
+- If you deposit and withdraw identical amounts
+- If you withdraw immediately after depositing
+- If you use the same address for multiple transactions
+- If your IP is visible (use VPN/Tor)
+
+### Can someone prove I made a transaction?
+
+No. Zero-knowledge proofs are designed so that:
+- Withdrawals cannot be linked to specific deposits
+- Multiple withdrawals cannot be linked together
+- There's no way to prove who initiated a transaction
+
+### What is an "anonymity set"?
+
+The anonymity set is the pool of deposits that your withdrawal could potentially come from. A larger anonymity set means better privacy. PrivacyLayer's anonymity set grows with each deposit.
+
+### Should I use a VPN?
+
+Yes, for additional privacy. While PrivacyLayer protects on-chain privacy, your IP address could reveal your activity to:
+- Your ISP
+- The dApp operator
+- Network observers
+
+Using a VPN or Tor adds a layer of network-level privacy.

+
+## Developer Questions
+
+### How do I integrate PrivacyLayer into my application?
+
+See our SDK documentation at `docs/SDK.md` for:
+- Installation instructions
+- API reference
+- Code examples
+- Best practices
+
+### What programming languages are supported?
+
+Primary SDK support:
+- **TypeScript/JavaScript:** Full-featured SDK
+- **Python:** Community SDK available
+- **Rust:** Core library available
+
+### Can I run my own relayer?
+
+Yes. Relayers help users submit transactions without needing XLM for fees. See `docs/RELAYER.md` for setup instructions.
+
+### How can I contribute?
+
+We welcome contributions! See:
+- `CONTRIBUTING.md` for guidelines
+- Open issues labeled "good first issue"
+- Our Discord for community discussion
+
+---
+
+## Troubleshooting
+
+### My withdrawal failed. What should I do?
+
+Common causes:
+1. **Insufficient balance:** Check the pool balance
+2. **Invalid note:** Verify your deposit note
+3. **Network issues:** Wait and retry
+4. **Already withdrawn:** Each note can only be used once
+
+### I deposited but can't see my funds
+
+Check:
+1. Correct network (Stellar mainnet/testnet)
+2. Transaction confirmed on Stellar
+3. Your deposit note is valid
+
+### The dApp is loading slowly
+
+This could be due to:
+1. High network traffic
+2. Merkle tree synchronization
+3. Browser performance
+
+Try:
+- Refreshing the page
+- Clearing browser cache
+- Using a different browser
