Privacy-Preserving DeFi Protocol Development
We design and build DeFi protocols with integrated privacy layers using zero-knowledge proofs (zk-SNARKs/zk-STARKs) or trusted execution environments (TEEs). Shield transaction amounts and counterparties while maintaining full on-chain auditability for compliance.

Privacy Technology Comparison: zk-Proofs vs. TEEs
Selecting the right privacy layer is critical for DeFi protocol security, compliance, and user experience. This table compares the two leading approaches for private computation.
| Feature | Zero-Knowledge Proofs (zk-Proofs) | Trusted Execution Environments (TEEs) |
|---|---|---|
Privacy Guarantee | Cryptographic (Mathematically Proven) | Hardware-Based (Intel SGX/AMD SEV) |
Trust Assumption | Trustless (No trusted third party) | Trust in Hardware Manufacturer & Attestation |
Development Complexity | High (Circuit Design, Proving Systems) | Medium (Secure Enclave Programming) |
Proving/Compute Overhead | High (Minutes for complex proofs) | Low (Near-native execution speed) |
Verification Cost (On-Chain) | High Gas (Verifier contract) | Low Gas (Attestation check only) |
Resistance to Side-Channel Attacks | High | Medium (Requires careful implementation) |
Ideal Use Case | Private payments, identity, compliance proofs | Private smart contract state, order book matching |
Chainscore Implementation Time | 8-12 weeks | 4-6 weeks |
Typical Project Cost | $80K - $200K+ | $40K - $100K |
