CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Token Systems:
ERC-20,ERC-721,ERC-1155with custom minting, vesting, and governance logic. - DeFi Protocols: Automated market makers (AMMs), staking pools, yield aggregators, and lending vaults.
- Enterprise Logic: Multi-signature wallets, access control systems, and cross-chain asset bridges.
- Security First: Every contract undergoes manual review and automated analysis with tools like Slither and MythX before deployment.
We deliver audited, battle-tested code with 99.9% uptime SLAs on mainnet, reducing your time-to-market from months to 2-4 weeks for an MVP.

Build vs. Buy: Custom Identity Feed vs. Generic Oracles
A technical and financial comparison between developing your own encrypted identity verification feed in-house versus leveraging Chainscore's specialized oracle service.
| Key Factor | Build In-House | Generic Oracle | Chainscore Custom Feed |
|---|---|---|---|
Time to Production | 6-12 months | 2-4 weeks | 4-8 weeks |
Initial Development Cost | $150K-$400K+ | $5K-$15K (setup) | $30K-$100K |
Annual Maintenance Cost | $80K-$200K (team) | 15-30% of setup fee | Optional SLA from $20K/year |
Data Source Integration | Your responsibility | Limited pre-set sources | Custom integrations (KYC providers, government DBs, etc.) |
Encryption & Privacy | Custom implementation risk | Basic or none | Zero-Knowledge proofs, selective disclosure |
Security Audit Burden | High (unaudited code) | Relies on oracle provider | Delivered pre-audited with OpenZeppelin patterns |

Frequently Asked Questions
Get clear answers on how we build secure, compliant, and scalable identity verification systems for Web3 applications.
Standard implementations take 4-8 weeks from kickoff to production. This includes requirements analysis, smart contract development, integration with your frontend, and a full security audit. For more complex use cases like cross-chain verification or custom credential schemas, timelines may extend to 12 weeks. We provide a detailed project plan within the first week of engagement.
