overview
SECURE FOUNDATIONS
Custom Smart Contract Development
Production-ready smart contracts built for security, gas efficiency, and long-term maintainability.
A secure, well-architected contract suite is the single most critical investment for any blockchain project's longevity and user trust.
Our deliverables include:
- Gas-optimized code using Solidity
0.8.x+and OpenZeppelin libraries. - Full test coverage with Hardhat or Foundry, including edge cases and attack vectors.
- Deployment scripts & documentation for seamless mainnet launch.
- Post-deployment support for upgrades and parameter tuning via transparent proxy patterns.
We specialize in complex DeFi primitives (AMMs, lending protocols, yield vaults), NFT ecosystems (ERC-721A, ERC-1155 with custom mechanics), and enterprise-grade token standards. Projects typically move from spec to audited testnet deployment in 3-6 weeks.

Business Outcomes for Your Fintech Platform
Our ZK-Rollup scaling solution for stablecoin transfers delivers concrete, measurable results that directly impact your platform's performance, security, and bottom line.
01
Radically Lower Transaction Costs
Move stablecoin settlements off-chain with zero-knowledge proofs, reducing gas fees by over 90% compared to mainnet. This enables micro-transactions and high-frequency transfers previously cost-prohibitive on Ethereum L1.

ZK-Rollup vs. Alternative Scaling Paths for Stablecoins
A technical and operational comparison of scaling solutions for high-volume, low-cost stablecoin transfers, highlighting why ZK-Rollups are the optimal choice for enterprise-grade applications.
| Scaling Factor | ZK-Rollup (Our Service) | Optimistic Rollup | Sidechain (e.g., Polygon PoS) | Application-Specific Chain |
|---|---|---|---|---|
Transaction Finality | < 10 minutes (with proofs) | 7 days (challenge period) | < 2 seconds | < 6 seconds |
Transaction Cost (Est.) | < $0.01 | < $0.02 | $0.001 - $0.01 | $0.001 - $0.05 |
Throughput (TPS) | 2,000+ | ~1,000 | ~7,000 | 1,000 - 10,000+ |
Security & Trust Model | Cryptographic Validity (Ethereum L1) | Economic & Fraud Proofs | Independent Validator Set | Independent Validator Set |
Capital Efficiency | High (instant withdrawals with proofs) | Low (7-day withdrawal delay) | High | High |
Sovereignty & Customization | High (custom logic, own sequencer) | High (custom logic, own sequencer) | Low (shared chain rules) | Maximum (full control) |
Time to Launch (with Chainscore) | 8-12 weeks | 10-14 weeks | 2-4 weeks | 3-6 months |
Development & Operational Complexity | High (requires expert team) | High (requires expert team) | Low (fork & deploy) | Highest (build from scratch) |
Ideal Use Case | High-value, high-frequency stablecoin transfers requiring L1 security | General-purpose apps where 7-day finality is acceptable | Applications prioritizing low cost & speed over L1 security | Projects needing maximum control, willing to bootstrap security |

Technical & Commercial FAQs
Get specific answers on timelines, costs, security, and technical implementation for your custom ZK-Rollup solution.
Our proven deployment process takes 4-8 weeks from kickoff to mainnet launch, depending on the complexity of your stablecoin logic and integration requirements. We follow a structured 4-phase approach: 1) Architecture & Design (1-2 weeks): Finalize circuit design and rollup architecture. 2) Core Development (2-4 weeks): Build the ZK circuits, sequencer, and prover. 3) Testing & Auditing (2 weeks): Conduct internal audits and simulate high-load scenarios. 4) Deployment & Integration (1 week): Deploy to your chosen L1 and integrate with your front-end. We provide a detailed project plan with weekly milestones.
