overview
INFRASTRUCTURE
Blockchain API Development
Scalable, secure APIs to power your Web3 applications and integrations.
- Custom Endpoints: Tailored for your specific data needs—token balances, NFT metadata, transaction history, gas prices.
- Multi-Chain Support: Connect to
EVMchains (Ethereum, Polygon, Arbitrum) andSolanavia a unified API. - Enhanced Performance: Built-in caching, webhook alerts, and sub-100ms response times for critical queries.
- Enterprise Security: API key management, rate limiting, DDoS protection, and SOC 2 compliant infrastructure.
Focus on your product logic while we handle the heavy lifting of node management, data indexing, and network reliability. Deploy a production-ready API in under 2 weeks.

BUILT FOR ENTERPRISE
Core Components of Your Compliance Sandbox
Our EVM-based sandbox framework is engineered as a modular system, providing the specific tooling and infrastructure needed to test, validate, and deploy compliant Web3 applications with confidence.
01
Isolated Test Environment
A dedicated, private EVM fork with configurable network parameters (gas fees, block times) and pre-loaded test tokens. Enables realistic stress testing without exposing your mainnet assets or data.
100%
Network Isolation
10+ Chains
Supported Forks
02
Regulatory Rule Engine
A programmable middleware layer that enforces compliance logic (e.g., KYC checks, transaction limits, jurisdiction filters) at the smart contract and RPC level before execution.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts for your protocol or dApp.
We architect and deploy custom smart contracts that form the secure, immutable backbone of your application. Our development process ensures gas efficiency, audit readiness, and compliance with industry standards like ERC-20, ERC-721, and ERC-1155.
Deliver a battle-tested, on-chain logic layer in weeks, not months.
- End-to-End Development: From initial design and
Solidity/Vypercoding to testing, deployment, and verification on mainnet. - Security-First Approach: Built with OpenZeppelin libraries and patterns, followed by rigorous internal audits before third-party review.
- Key Deliverables: Production-ready contracts, comprehensive test suites, deployment scripts, and technical documentation.
Infrastructure Decision Matrix
Build vs. Buy vs. Our Managed Framework
A clear comparison of the time, cost, and risk involved in developing a compliant EVM sandbox using different approaches.
| Key Factor | Build In-House | Buy Generic Solution | Chainscore Managed Framework |
|---|---|---|---|
Time to Launch (MVP) | 6-12+ months | 3-6 months | 4-8 weeks |
Initial Development Cost | $250K - $750K+ | $100K - $300K (license + integration) | $50K - $150K (project-based) |
Regulatory Compliance Coverage | Your responsibility (high risk) | Generic templates (moderate risk) | Tailored to your jurisdiction (low risk) |
Smart Contract Security | Requires full audit cycle | Vendor-dependent, may lack audits | Pre-audited modules + custom audit |
Integration with Legacy Systems | Custom, complex development | Limited APIs, may require workarounds | Pre-built adapters for KYC/AML/CRM |
Ongoing Maintenance & Updates | Full internal team required | Vendor roadmap, potential upgrade fees | Included in optional SLA |
Scalability & Multi-Chain Support | Significant re-architecture needed | Often chain-locked or limited | Built-in architecture for Ethereum, Polygon, Arbitrum, Base |
Total Cost of Ownership (Year 1) | $400K - $1M+ | $150K - $400K | $80K - $200K (with SLA) |
EVM Regulatory Sandbox
Frequently Asked Questions
Common questions from CTOs and compliance leads about designing and deploying a compliant on-chain testing environment.
A complete EVM-based sandbox framework from design to deployment typically takes 4-8 weeks. This includes a 1-week discovery and scoping phase, 2-3 weeks for core architecture and smart contract development, 1-2 weeks for integration with monitoring/analytics tools, and 1-2 weeks for security review and final deployment. For clients with pre-defined compliance rules, we've delivered MVP sandboxes in as little as 2 weeks.
