overview
CORE INFRASTRUCTURE
Custom Smart Contract Development
Secure, audited smart contracts built to your exact business logic and deployed on your chosen blockchain.
- Custom Logic: Tailored
Solidity/Rustcontracts for DeFi protocols, NFT collections, DAOs, and enterprise use cases. - Security Rigor: Built with
OpenZeppelinstandards and undergo multiple audit stages before mainnet deployment. - Deployment & Verification: Full deployment pipeline, including testnet validation, mainnet launch, and block explorer verification.
We deliver battle-tested contracts with a 99.9% security audit pass rate and typical project timelines of 3-6 weeks from spec to mainnet.

Infrastructure Decision Matrix
Build vs. Buy: Managing Smart Contract State Archival
A detailed comparison of the total cost of ownership, risk, and operational overhead between developing an archival node solution in-house versus leveraging Chainscore's managed service.
| Factor | Build In-House | Chainscore Managed Service |
|---|---|---|
Initial Development Timeline | 6-12+ months | 4-8 weeks |
Upfront Engineering Cost | $250K - $600K+ | $0 |
Security & Audit Burden | High (Your responsibility) | Low (Pre-audited, SOC 2 compliant) |
Infrastructure Complexity | High (Node ops, sync, storage) | None (Fully abstracted API) |
Ongoing Maintenance & DevOps | 2-3 FTE Engineers | Fully Managed by Chainscore |
Historical Data Integrity | Risk of chain reorg corruption | Guaranteed with cryptographic proofs |
Query Performance & Latency | Variable (depends on setup) | < 100ms P95 latency SLA |
Multi-Chain Support Effort | Per-chain implementation | Single API (Ethereum, Polygon, Arbitrum, etc.) |
Total Cost of Ownership (Year 1) | $500K - $1.2M+ | Starting at $75K/year |
Time to First Historical Query | Months (after sync) | Immediate |
