CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155implementations with advanced features like vesting, staking, and governance. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, and yield aggregators with gas-optimized logic.
- Enterprise Logic: Multi-signature wallets, access control systems, and verifiable on-chain workflows for business processes.
- Full Audit Trail: Every contract includes comprehensive documentation,
NatSpeccomments, and a security review report.
We deliver contracts that are secure by design, reducing your audit costs and mitigating the risk of catastrophic exploits.
From a 2-week MVP to a complex multi-chain protocol, we provide the technical foundation you can launch with confidence. Our engineers are fluent in Solidity, Rust (Solana), and Vyper to match your chain of choice.

Why StarkNet's ZK-Proof Warranty is the Superior Choice
ZK Verification vs. Traditional & Basic Blockchain Methods
A technical comparison of verification methodologies, highlighting the security, cost, and performance advantages of Chainscore's StarkNet-based ZK-Proof Warranty Verification service over conventional approaches.
| Verification Factor | Traditional Oracles | Basic On-Chain Logic | Chainscore ZK-Proof Warranty |
|---|---|---|---|
Data Integrity & Tamper-Proofing | Centralized point of failure | Limited to on-chain data only | Cryptographically proven off-chain computation |
Verification Cost (Gas) | High (frequent updates) | Variable (on-chain execution) | Ultra-low (single proof for multiple claims) |
Settlement Finality | Minutes to hours | Block time dependent | Sub-second with StarkNet validity proofs |
Security Model | Trust in external API | Trust in public mempool | Trustless cryptographic proof |
Scalability (Claims/Second) | < 100 | < 1,000 | 10,000+ |
Fraud Detection | Reactive (post-facto) | Limited to predefined rules | Proactive (proofs guarantee correctness) |
Implementation Timeline | 2-4 weeks | 4-8 weeks | 4-8 weeks (with proven security) |
Ongoing Operational Overhead | High (API management, monitoring) | Medium (gas optimization, upgrades) | Low (managed proof generation & submission) |
Typical Use Case | Simple price feeds | Basic eligibility checks | Complex warranty logic, financial settlements, compliance proofs |
