SIP Protocol
Privacy Infrastructure for Solana
Stealth addresses + Pedersen commitments + Viewing keys for compliance
Zypherpunk Hackathon Winner
Security is Non-Negotiable
Our program handles user funds with complex cryptography. Professional audit is mandatory before mainnet.
Handles Real Value
The Solana program processes shielded transfers of SOL and SPL tokens. User funds must be protected.
Cryptographic Complexity
Pedersen commitments, stealth addresses, and ZK proof verification require expert review.
Pre-Mainnet Critical Path
Security audit is the gating item for mainnet deployment. No audit = no mainnet.
Institutional Trust
Audited code unlocks enterprise adoption. DAOs and institutions require audit reports.

Focused scope: Solana Anchor program for privacy-preserving transfers
Source Files
| File | LOC | Description |
|---|---|---|
lib.rs | ~650 | Main program: initialize, shielded_transfer, claim_transfer, admin functions |
commitment/mod.rs | ~200 | Pedersen commitment verification and format validation |
zk_verifier/mod.rs | ~200 | ZK proof deserialization and verification logic |
| Total | ~1,050 | Solana Anchor program |
Program Instructions
| Instruction | Risk | Description |
|---|---|---|
initialize | Low | One-time config setup with authority |
shielded_transfer | Critical | SOL/SPL transfers with hidden amounts |
shielded_token_transfer | Critical | SPL token variant with mint validation |
claim_transfer | Critical | Recipient claims with nullifier + ZK proof |
claim_token_transfer | Critical | SPL token claim variant |
verify_commitment | Medium | On-chain Pedersen verification utility |
verify_zk_proof | High | ZK proof verification for Noir proofs |
set_paused / update_fee | Low | Admin functions with authority check |
Cryptographic Privacy Stack
Stealth Addresses
EIP-5564 style one-time recipient addresses. Prevents linkability between transactions.
Pedersen Commitments
C = v*G + r*H hides amounts cryptographically. Any amount, no fixed pools.
Viewing Keys
Selective disclosure for compliance. Auditors can verify without compromising user privacy.
Noir ZK Proofs
Funding, validity, and fulfillment proofs. Browser-compatible WASM verification.
Why SIP, Not Mixers
Pool-based privacy exposes amounts. Cryptographic privacy hides everything.
| Feature | SIP Protocol | Pool Mixers |
|---|---|---|
| Privacy Method | Cryptographic (Pedersen) | Pool Mixing |
| Amount Privacy | Hidden (commitments) | Visible on-chain |
| Viewing Keys | Native support | None |
| Amount Correlation | Impossible | Vulnerable |
| Pool Constraints | Any amount | Fixed sizes |
| Regulatory Risk | Low (compliance-first) | High (mixer) |
Proven Traction

Solo Founder, SIP Protocol • 🇮🇩 Indonesia
💡 About
Indonesian developer building the privacy standard for Web3. Blockchain architect with $24,300+ across 6 wins (2024-2026) including $10K Superteam grant, MonkeDAO 1st, Zypherpunk Winner (3 tracks), and more. Focused on cryptographic privacy, cross-chain infrastructure, and high-performance systems. Privacy is a right, not a feature.
🔐 Why Privacy?
Remember when HTTP was the norm? We now consider sites without HTTPS dangerous. Web3 is in its HTTP era — transparency is the default, but crime follows money. As Web3 matures, privacy becomes essential defense. SIP doesn't ignore blockchain fundamentals — it makes them better. Privacy isn't hiding, it's protection.
⚡ Why Solo?
Many doubt solo founders. I think differently. After building with teams, I learned that wrong teams are more dangerous than external threats — they're internal ones. Good projects with good teams still die from lack of synchronization. Solo means pure execution.
