CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 specialists for your token, DeFi, or NFT project.
- Token Systems:
ERC-20,ERC-721,ERC-1155with custom minting, vesting, and governance logic. - DeFi Protocols: Automated Market Makers (AMMs), liquidity pools, staking, and yield farming vaults.
- Enterprise Logic: Multi-signature wallets, access control, upgradeable contracts using
OpenZeppelinpatterns.
Every contract undergoes rigorous internal review and is built for audit-readiness, significantly reducing time and cost for third-party security audits from firms like CertiK or Quantstamp.
We deliver fully documented, tested, and deployable contracts within 2-4 weeks for an MVP, ensuring you move from concept to mainnet with confidence and speed.

Architectural Comparison
ZK Oracle Proofs vs. Traditional Oracle Consumption
A technical and operational comparison between Chainscore's ZK Oracle Proofs and conventional oracle data feeds for EVM smart contracts.
| Feature / Metric | Traditional Oracle Consumption | Chainscore ZK Oracle Proofs |
|---|---|---|
Data Integrity Guarantee | Trust-based on reputation | Cryptographically verified with ZK proofs |
On-Chain Data Footprint | Large (full data payload) | Minimal (compact proof only) |
Gas Cost for Verification | High (data processing + logic) | Up to 70% lower (proof verification only) |
Latency to On-Chain Finality | Variable (3-12+ blocks) | Predictable (< 2 blocks) |
Security Model | Honest majority / Economic slashing | Cryptographic soundness (no trust assumptions) |
Supported Data Types | Primarily numeric/price feeds | Any verifiable computation (prices, RNG, off-chain state) |
Implementation Complexity | Moderate (oracle client integration) | Low (single verification contract) |
Ongoing Operational Overhead | High (node monitoring, fallbacks) | Minimal (set-and-forget verification) |
Ideal Use Case | Simple price feeds for DeFi | Complex logic, gaming, compliance, high-value settlements |
