CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built to your exact specifications.
- Protocol Development: Custom
ERC-20,ERC-721,ERC-1155, and bespoke token standards. - DeFi & DEX: Automated Market Makers (AMMs), liquidity pools, staking, and yield farming contracts.
- NFT Ecosystems: Minting, marketplaces, dynamic metadata, and royalty enforcement.
- Utility & Governance: Multi-signature wallets, DAO frameworks, and access control systems.
We deliver battle-tested contracts with a comprehensive audit report, reducing your time-to-audit by weeks and mitigating critical vulnerabilities before mainnet deployment.
Our engineers write in Solidity 0.8+ and Vyper, leveraging OpenZeppelin libraries and following ConsenSys best practices. We provide full documentation and a deployment pipeline for your team.

Architectural Comparison
ZK KYC vs. Traditional KYC for Borderless Payments
A technical and operational breakdown of privacy-preserving Zero-Knowledge KYC versus conventional centralized systems for global payment platforms.
| Feature | Traditional KYC | ZK KYC (Chainscore) |
|---|---|---|
Data Privacy & User Sovereignty | ||
Compliance Proof | Centralized Database | On-Chain ZK Proof |
Cross-Border Data Transfer | Legal Complexity (GDPR, etc.) | No PII Transfer Required |
Onboarding Friction | High (Document Upload, Wait Time) | Low (One-Time Verification, Reusable Proof) |
Developer Integration | Months (Custom API Work) | Weeks (Standard SDKs & Templates) |
Audit Trail & Transparency | Opaque, Proprietary | Transparent, Verifiable Proofs |
Ongoing Maintenance Cost | High (Licensing, Storage, Security) | Predictable (Protocol-Based) |
Time to Launch New Market | 3-6 Months | 4-8 Weeks |
Estimated Annual TCO for Startup | $200K+ | $50K - $150K |

Frequently Asked Questions
Get clear, technical answers about implementing compliant, privacy-preserving identity verification for your global payment rails.
Our solution is architected to meet global AML/CFT standards like FATF Travel Rule and EU's AMLD6. We implement ZK-SNARK proofs that verify a user's credentials (e.g., passport, address) are valid and from a trusted issuer, without revealing the underlying data. The protocol outputs a cryptographically signed attestation that your payment system can verify on-chain, providing a clear audit trail for regulators while keeping user data private. We work with legal partners to ensure the verification logic aligns with jurisdictional requirements.
