We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Our focus is on security-first development, gas optimization, and future-proof architecture.
Compliant Confidential Transaction System
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Security Audits: Every contract undergoes internal review and formal verification before deployment.
- Standard Compliance: Built with
OpenZeppelinlibraries and adherence toERC-20,ERC-721, and other established standards. - Deployment & Management: Full lifecycle support from testnet to mainnet, including upgradeable proxy patterns.
Deliver a secure, audited MVP in as little as 2-3 weeks, with a 99.9% uptime SLA for live contracts.
Core Architecture & Compliance Features
Our system is engineered from the ground up for institutional adoption, combining zero-knowledge privacy with enforceable compliance. We deliver the technical rigor and regulatory safeguards required for high-value transactions.
Formal Verification & Audits
Every core circuit and smart contract undergoes formal verification and multiple independent audits (e.g., Trail of Bits, Quantstamp). We provide verifiable proof of correctness and security.
Gas-Optimized Solidity & Circuits
Our contracts are built with Solidity 0.8+ and OpenZeppelin libraries, optimized for minimal gas consumption. ZK circuits are designed for efficient proof generation, keeping user costs predictable.
Business Outcomes for Institutional Clients
Our Compliant Confidential Transaction System is engineered to meet the stringent requirements of institutional finance, delivering measurable security, operational, and compliance advantages.
Regulatory Compliance by Design
Pre-built compliance modules for AML/KYC, Travel Rule (FATF 16), and sanctions screening, integrated directly into the transaction flow. Eliminate manual review bottlenecks and ensure audit trails are immutable and verifiable.
Institutional-Grade Security & Privacy
Zero-Knowledge Proofs and confidential smart contracts ensure transaction amounts and counterparty details remain private on-chain, while providing regulators with selective disclosure capabilities. Built on audited cryptographic libraries.
Operational Efficiency at Scale
Automate settlement and reconciliation with atomic, final transactions. Reduce operational overhead by up to 70% compared to legacy correspondent banking networks, with sub-2-second finality for cross-border payments.
Seamless Integration & Customization
Deploy a white-label solution or integrate via our robust APIs into existing treasury, custody, or trading platforms. Full support for multi-chain environments (EVM, Cosmos, Solana) with custom rule engines.
Build vs. Buy: Compliant Privacy Systems
Evaluating the total cost, risk, and time investment of developing a compliant privacy layer in-house versus partnering with Chainscore Labs.
| Factor | Build In-House | Partner with Chainscore |
|---|---|---|
Time to Market | 9-18 months | 6-12 weeks |
Initial Development Cost | $250K - $750K+ | $50K - $150K |
Regulatory & Compliance Overhead | Your responsibility | Pre-built, audited modules |
Security & Audit Burden | High (multiple external audits required) | Low (leverages pre-audited, battle-tested core) |
Team Requirements | Specialized cryptographers, Solidity devs, legal | Your integration engineers + our experts |
Ongoing Maintenance & Upgrades | Full internal team cost | Optional SLA from $25K/year |
Integration Complexity | High (custom integration for each chain/app) | Standardized APIs & SDKs for major EVM chains |
Audit Trail & Reporting | Custom build required | Built-in, regulator-ready compliance dashboard |
Our Delivery Methodology
We deliver compliant confidential transaction systems through a structured, security-first process. Our methodology ensures regulatory adherence, technical excellence, and rapid deployment for financial institutions and Web3 enterprises.
Regulatory & Technical Discovery
We begin with a deep-dive workshop to map your specific compliance requirements (AML, KYC, OFAC) to technical architecture. This phase defines the privacy model (ZKPs, MPC, TEEs) and selects the optimal base layer (Ethereum L2, Polygon, Hyperledger).
Architecture & Protocol Design
Our architects design a system blueprint balancing confidentiality, auditability, and performance. We specify the cryptographic primitives, data flow, and on/off-chain components, ensuring the design is regulator-ready and scalable from day one.
Secure Development & Integration
Engineers implement the system using battle-tested libraries (ZoKrates, Noir) and follow secure coding standards. We integrate with existing identity providers, custodians, and reporting tools, ensuring seamless operation within your tech stack.
Compliance Validation & Audit
Before deployment, the complete system undergoes rigorous third-party security audits and a compliance review. We produce an attestation report detailing how the system meets regulatory obligations, providing evidence for internal and external stakeholders.
Staged Deployment & Monitoring
We deploy to a testnet or private environment for final validation, followed by a phased mainnet rollout. Real-time monitoring for anomalous patterns and automated compliance reporting dashboards are established to ensure ongoing integrity.
Ongoing Support & Evolution
Post-launch, we provide technical support, handle protocol upgrades, and assist with adapting to new regulatory guidance. Our team ensures your confidential transaction system remains secure, compliant, and performant as your business scales.
Frequently Asked Questions
Get clear answers on how our confidential transaction system works, its security, and how we deliver it for your project.
Our system uses Zero-Knowledge Proofs (ZKPs) and secure multi-party computation (MPC) to encrypt transaction details on-chain. While amounts and participants are hidden from the public ledger, a designated regulatory module (like a compliance oracle) can be granted permissioned access to verify transactions against AML/CFT rules. This creates a privacy layer that protects user data while maintaining full auditability for authorized entities.
