CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts for your token, DeFi, or NFT project.
From initial concept to mainnet launch, we deliver contracts you can trust with real user funds.
Our typical deliverables include:
- Token Systems:
ERC-20,ERC-721,ERC-1155with custom minting, vesting, and governance logic. - DeFi Protocols: Custom AMMs, lending/borrowing pools, staking, and yield aggregators.
- Security & Compliance: Integration of
OpenZeppelinlibraries, comprehensive unit/integration testing, and audit report remediation.
We partner with your team for a 2-4 week MVP delivery or ongoing development. All code is documented, version-controlled, and deployed with CI/CD pipelines for seamless iteration.

Technical & Operational Comparison
ZK Bridges vs. Traditional Bridging Solutions
A detailed comparison of security, performance, and cost between next-generation Zero-Knowledge interoperability and conventional bridging methods.
| Evaluation Factor | Traditional Bridges (HTLC/Multi-Sig) | Chainscore ZK Bridges |
|---|---|---|
Security Model | Trusted validators or committees | Cryptographic (ZK-SNARKs/STARKs) |
Trust Assumption | High (requires trust in operators) | Minimal (trustless, verifiable) |
Vulnerability Surface | High (target for exploits, key theft) | Low (no central custody points) |
Finality & Latency | High (10-30 mins for confirmations) | Low (< 2 minutes) |
Cross-Chain Message Cost | Variable, often high gas fees | Optimized, predictable gas costs |
Development & Audit Time | 6-9 months + extensive audits | 4-8 weeks + streamlined audit |
Protocol Flexibility | Limited to asset transfers | Full smart contract state interoperability |
Ongoing Operational Overhead | High (monitoring, key management) | Managed service with 99.9% SLA |
Total Cost of Ownership (Year 1) | $300K-$750K+ (build & maintain) | $80K-$200K (managed service) |
Ideal For | Simple asset transfers with high trust | Secure DeFi, gaming, institutional use |

Our Delivery Process: From Architecture to Mainnet
We deliver production-ready ZK interoperability infrastructure through a structured, milestone-driven process. This ensures technical alignment, predictable timelines, and a secure, scalable launch.
01
Architecture & Protocol Design
We define your interoperability model, select optimal ZK proving systems (e.g., Plonk, Groth16, Halo2), and design the trust-minimized bridge or messaging protocol architecture.

Frequently Asked Questions on ZK Interoperability
Get clear, specific answers to the most common questions from CTOs and technical founders evaluating zero-knowledge interoperability solutions.
From architecture to mainnet deployment, a standard cross-ecosystem ZK bridge takes 4-8 weeks. This includes 1-2 weeks for design and security review, 2-4 weeks for core development and internal testing, and 1-2 weeks for audit preparation and final deployment. Complex multi-chain or custom proving schemes can extend this timeline, which we scope precisely during the initial discovery phase.
