CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Full Lifecycle Development: From initial spec and
Solidity/Rustcoding to deployment and upgrade management. - Security-First: Every contract undergoes manual review and automated analysis with tools like
SlitherandMythX. - Gas Optimization: We deliver contracts with up to 40% lower gas costs through efficient patterns and bytecode optimization.
We deliver audit-ready code in 2-4 weeks, backed by a 99.9% uptime SLA for deployed contracts.

The Infrastructure Investment Decision
Build In-House vs. Our Managed SDK
Compare the total cost, risk, and time investment required to develop and maintain a cross-chain privacy layer internally versus leveraging our production-ready SDK.
| Key Factor | Build In-House | Chainscore Managed SDK |
|---|---|---|
Time to Production | 6-12 months | 4-8 weeks |
Initial Development Cost | $250K - $500K+ | $75K - $150K |
Core Expertise Required | ZK-SNARKs, MPC, Cross-Chain Messaging | Your Application Logic |
Security & Audit Burden | High (Your Responsibility) | Low (Pre-Audited, Continuous Monitoring) |
Ongoing Maintenance | Dedicated 2-3 Engineer Team | Fully Managed, Optional SLA |
Protocol Upkeep (e.g., ZK Circuits) | Manual, Costly Upgrades | Automatic, Backward-Compatible Updates |
Supported Ecosystems | Limited to Your Build | Ethereum, Polygon, Arbitrum, Base, Solana, Sui |
Total Cost of Ownership (Year 1) | $400K - $800K+ | $100K - $200K |
Risk Profile | High (Unaudited Code, Protocol Drift) | Low (Audited, Insured, Proven Track Record) |

PROVEN FRAMEWORK
Our Delivery Methodology
We deliver production-ready privacy SDKs through a structured, transparent process designed for technical teams. From initial architecture to final audit, our methodology ensures security, interoperability, and rapid integration.
01
Architecture & Specification
We begin with a collaborative design session to define your privacy model (ZK-SNARKs, MPC, TEEs) and integration points across EVM, Solana, and Cosmos ecosystems. Deliverables include a technical spec and integration roadmap.
1-2 weeks

3+ ecosystems
Cross-Chain Scope
02
Core SDK Development
Our engineers build the modular SDK in Rust/TypeScript, implementing zero-knowledge circuits (Circom, Halo2), secure enclaves, or multi-party computation protocols. Code follows OWASP and blockchain security best practices.
