overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We deliver contracts that are secure by design, not patched after deployment.
- Custom Logic: Build bespoke DeFi primitives, governance systems, and asset management contracts.
- Gas Optimization: Reduce user transaction costs by 15-40% through expert bytecode-level tuning.
- Full Audit Support: Contracts are developed with
SlitherandMythXintegration, prepped for third-party audits.
From ERC-20/721/1155 tokens to complex cross-chain bridges, we ensure your contracts are reliable, upgradeable, and ready for mainnet. Typical delivery for a core protocol MVP is 3-4 weeks.

PROVEN FRAMEWORK
Our Delivery Methodology
We deliver production-ready ZK-Rollup infrastructure through a structured, milestone-driven process designed for technical founders. Our methodology ensures predictable delivery, transparent communication, and a secure, scalable final product.
01
Architecture & Design Sprint
A collaborative 2-week sprint to define your privacy-first settlement layer's core architecture. We deliver a technical specification covering ZK circuit design, data availability strategy, and sequencer/decentralization roadmap.

The Infrastructure Decision for Your Privacy-First Application
Build vs. Buy: Custom ZK-Rollup vs. Generic L2
A detailed comparison of the cost, time, and risk involved in developing a custom ZK-Rollup settlement layer in-house versus partnering with Chainscore's specialized development team.
| Key Factor | Build In-House | Generic Public L2 | Chainscore Custom ZK-Rollup |
|---|---|---|---|
Time to Production | 9-18 months | Immediate | 8-16 weeks |
Upfront Development Cost | $300K - $1M+ | $0 (gas fees only) | $75K - $250K |
Custom Privacy Logic | Full control | None (public by default) | Tailored to your use case |
Prover & Verifier Setup | Build from scratch | Uses chain's default | Optimized & pre-audited |
Cryptographic Expertise Required | Senior ZK researchers (2-3) | Minimal | Included in our team |
Security Audit Burden | Your responsibility (high risk) | Shared with L2 provider | Included + formal verification options |
Data Availability Strategy | Your design & implementation | Managed by L2 | Custom (Ethereum, Celestia, etc.) |
Ongoing Node Operations | Your DevOps team | Managed by L2 provider | Fully managed SLA (99.9% uptime) |
Total Cost of Ownership (Year 1) | $450K - $1.2M+ | Low, but limited flexibility | $125K - $350K (predictable) |
Competitive Advantage | Theoretical, if successful | None (same as competitors) | Built-in via custom privacy & scaling |
