COMPETITIVE ADVANTAGES
Business Outcomes: Why Privacy Matters for Your Platform
Privacy-enhanced confidential atomic swaps are not just a technical feature; they are a strategic business asset. Here’s how they deliver tangible value for your platform and users.
01
Institutional-Grade Compliance
Our confidential swap architecture enables selective disclosure for audits and regulators, allowing you to meet AML/CFT requirements without exposing all user data. This builds trust with enterprise partners and opens regulated markets.

Technical & Operational Comparison
Confidential Swaps vs. Standard Atomic Swaps
A detailed breakdown of how privacy-enhanced confidential atomic swaps differ from traditional atomic swaps in security, functionality, and operational overhead.
| Feature / Specification | Standard Atomic Swaps | Chainscore Confidential Swaps |
|---|---|---|
Privacy Level | Transparent (On-chain) | Confidential (Zero-Knowledge Proofs) |
Transaction Visibility | Public amounts & participants | Hidden amounts, shielded participants |
Core Technology | Hash Time-Locked Contracts (HTLCs) | ZK-SNARKs / Bulletproofs + HTLCs |
Development Complexity | High (Custom logic, security risks) | Managed (Pre-audited, modular) |
Time to Integrate | 3-6 months (in-house) | 4-8 weeks (with our SDK) |
Security Posture | Your responsibility (unaudited) | Enterprise-grade (audited by Halborn, CertiK) |
Cross-Chain Support | Limited (UTXO-based chains) | Broad (EVM, Cosmos, Solana via bridges) |
Regulatory Readiness | Low (Fully transparent ledger) | High (Selective disclosure capabilities) |
Typical Implementation Cost | $150K+ (Engineering months) | $50K - $150K (Fixed-scope project) |
Ongoing Maintenance | Full in-house DevOps required | Optional SLA with 99.9% uptime |

Frequently Asked Questions
Get clear answers on development timelines, security, and process for building trustless, private cross-chain exchange protocols.
A production-ready confidential atomic swap protocol typically takes 4-8 weeks from kickoff to mainnet deployment. This includes 2 weeks for architecture and ZKP circuit design, 2-3 weeks for core smart contract and off-chain relayer development, and 1-2 weeks for security audits and final testing. For more complex multi-asset or multi-chain systems, timelines extend to 10-12 weeks.
