overview
CORE INFRASTRUCTURE
Custom Smart Contract Development
Secure, audited smart contracts built for your specific business logic and compliance needs.
From tokenomics to complex DeFi logic, we translate your requirements into immutable, gas-optimized code.
- Custom Token Standards:
ERC-20,ERC-721,ERC-1155, and bespoke implementations with minting, vesting, and governance modules. - DeFi & DEX Protocols: Automated Market Makers (AMMs), liquidity pools, staking mechanisms, and yield aggregators.
- Enterprise Logic: Multi-signature wallets, access control systems, and compliant asset issuance frameworks.
- Full Audit Trail: Every contract undergoes internal review and is prepared for third-party audits from firms like CertiK or Quantstamp.

Why a dedicated local execution environment is critical for StarkNet
Local Sandbox vs. Public Testnet Development
Compare the development experience, cost, and speed of building StarkNet applications using a public testnet versus Chainscore's Cairo Local Execution Engine.
| Development Factor | Public Testnet | Chainscore Local Engine |
|---|---|---|
Iteration Speed | Minutes to hours per test | Sub-second feedback loop |
Gas Costs for Testing | $50-$200+ per month | $0 (no transaction fees) |
Environment Control | Shared, unpredictable state | Deterministic, isolated state |
CI/CD Integration | Complex, rate-limited | Native, seamless integration |
Debugging Capabilities | Limited to transaction logs | Full Cairo VM trace & step-through |
Network Latency | 100ms - 2s+ | < 10ms |
Time to First Prototype | 2-4 weeks | 2-4 days |
Team Onboarding Complexity | High (wallet setup, faucets) | Low (single Docker command) |
Total Annual Cost (Dev Time + Fees) | $25K - $100K+ | $15K - $50K |
