CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Custom Tokenomics: Design and implement
ERC-20,ERC-721, andERC-1155tokens with vesting, staking, and governance modules. - DeFi Protocols: Build automated market makers (AMMs), lending/borrowing pools, and yield aggregators with sub-second finality.
- Enterprise Logic: Develop bespoke contracts for supply chain, identity, and asset tokenization with multi-signature controls.
We deliver a fully tested, documented, and deployable contract suite in 2-4 weeks, backed by a 99.9% uptime SLA for mainnet deployments.

The Strategic Choice for Your Web3 Product
Build vs. Buy: On-Chain Subscription Solutions
A detailed comparison of the total cost, risk, and time investment required to develop a secure, production-ready recurring billing system in-house versus partnering with Chainscore Labs.
| Key Factor | Build In-House | Buy with Chainscore |
|---|---|---|
Time to Production Launch | 6-12+ months | 4-8 weeks |
Initial Development Cost | $150K - $400K+ | From $50K |
Security & Audit Overhead | High (unaudited risk) | Low (pre-audited, battle-tested) |
Ongoing Maintenance Burden | Full-time engineering team | Managed service with optional SLA |
Feature Set (e.g., cancellations, upgrades, trials) | Basic, built from scratch | Comprehensive, production-proven |
Multi-Chain Support (EVM, Solana, etc.) | Custom integration per chain | Native, configurable deployment |
Total Cost of Ownership (Year 1) | $200K - $500K+ | $75K - $200K |
Guaranteed Uptime & Monitoring | Your responsibility | 99.9% SLA with 24/7 alerting |

Frequently Asked Questions
Get clear answers on our process, security, and timelines for building your custom subscription billing system.
A standard implementation takes 4-8 weeks from kickoff to mainnet deployment. This includes smart contract development, integration with your frontend, and security audits. Complex features like multi-chain support or advanced payment logic can extend this timeline. We provide a detailed project plan within the first week.
