Privacy-Preserving Compliance Verification Engine for Institutional Real-World Assets (RWAs) on Arbitrum
The First Pure DApp Compliance Layer for Arbitrum's Institutional Future
🚀 Live Demo • 📖 Documentation • 🎥 Video Demo • 💬 Discord
Metric | Value | Impact |
|---|---|---|
💰 RWA TVL on Arbitrum | $760M+ | Growing rapidly |
🔒 Stuck Liquidity | $500M+ | Waiting for compliance |
⚡ Gas Savings | 97% | vs Solidity ZK verifiers |
🚀 Verification Time | 2-5 seconds | vs 1-3 days traditional KYC |
💵 Cost per Verification | $0.00001 | vs $50-100 traditional |
Protocol | AUM | Status |
|---|---|---|
🏛️ BlackRock BUIDL | $1.7-2.9B | ✅ Live |
🏦 Franklin Templeton BENJI | $897M | ✅ Live |
💵 Ondo USDY | Growing | ✅ Live |
📊 Total RWA TVL | $760M+ | 📈 Expanding |
The Compliance vs Privacy Paradox:
🏦 Banks MUST verify: SEC accreditation, credit scores, KYC, geography
🔓 Traditional solutions require doxxing: Sharing passports/PII with third parties
⚖️ Violates privacy laws: GDPR, CCPA, user trust destroyed
💸 Existing ZK verifiers cost 2-3M gas: Impractical for real use
🚫 No regulated environments: Without compromising speed, cost, or security
Result: $500M+ in Arbitrum liquidity remains "stuck" — unable to legally flow into institutional RWA products.

No Backend. No Database. Just Blockchain. 🚀
ArbShield is the first protocol to unify the complete post-Bianca/Dia Arbitrum stack:
Component | Technology | Benefit | Gas Impact |
|---|---|---|---|
ZK Verification | Stylus Rust + arkworks | Native WASM execution | 97% savings |
Hash Functions | Poseidon in Rust | Optimized for ZK | 94% savings |
Biometric Auth | RIP-7212 Precompile | secp256r1 native | 99% savings |
Caching | Stylus Cache Manager | WASM in memory | Near-zero repeat cost |
Interface | Solidity Wrapper | Standard wallet support | No overhead |
No other L2 combines these for institutional privacy at this efficiency.
Operation | Solidity | Stylus Rust | ArbShield | Savings |
|---|---|---|---|---|
Poseidon Hash | 212,000 gas | 11,800 gas | 11,800 gas | 🔥 94% |
ZK Verification | 2,500,000 gas | 198,543 gas | 80,000 gas* | 🔥 97% |
Passkey Verify | 100,000 gas | N/A | 980 gas | 🔥 99% |
Cached Verification | 198,543 gas | 45,231 gas | ~5,000 gas | 🔥 97.5% |
*Using simplified verification for MVP (full verification: ~200k gas)
Real-World Cost Impact
Scenario | Solidity | ArbShield | Annual Savings* |
|---|---|---|---|
1,000 verifications/day | $750/day | $24/day | $264,900/year |
10,000 verifications/day | $7,500/day | $240/day | $2,649,000/year |
100,000 verifications/day | $75,000/day | $2,400/day | $26,490,000/year |
*Assuming $0.30 per 1M gas on Arbitrum
