CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your decentralized applications.
From tokenomics to complex DeFi logic, we translate your business requirements into robust, immutable code.
- Custom Token Development:
ERC-20,ERC-721,ERC-1155, and SPL tokens with tailored minting, vesting, and governance logic. - DeFi & dApp Logic: Automated Market Makers (AMMs), staking pools, lending protocols, and NFT marketplaces.
- Security & Audits: Development aligned with OpenZeppelin standards, followed by third-party audits from firms like CertiK or Quantstamp.
- Full Lifecycle Support: Development, deployment, verification on Etherscan/Solscan, and ongoing maintenance.

Strategic Infrastructure Decision
Build a Custom Bridge vs. Using a Generic Protocol
Choosing the right foundation for your cross-chain NFT loyalty program impacts security, cost, and time-to-market. This comparison outlines the trade-offs between developing a custom solution in-house, using a generic third-party bridge, and partnering with Chainscore Labs for a tailored integration.
| Key Factor | Build In-House | Use Generic Bridge | Chainscore Custom Integration |
|---|---|---|---|
Time to Market | 6-12 months | 2-4 weeks | 4-8 weeks |
Upfront Development Cost | $150K - $400K+ | $0 - $10K (API fees) | $50K - $150K |
Security & Audit Burden | High (Your responsibility) | Medium (Dependent on provider) | Low (Pre-audited modules + full audit) |
Custom Logic for Loyalty Rules | Full flexibility | None / Highly limited | Tailored to your program |
Brand & UX Control | Complete control | Minimal (Provider's UI) | Full white-label control |
Ongoing Maintenance & Upgrades | Your team (2+ FTE) | Provider's roadmap | Optional SLA with dedicated support |
Cross-Chain Fee Optimization | You build it | Fixed by provider | Built-in dynamic fee routing |
Vendor Lock-in Risk | None | Very High | None (You own the code) |
Typical Total Cost (Year 1) | $300K - $600K+ | $15K - $50K+ (variable fees) | $80K - $200K (predictable) |

Frequently Asked Questions
Get clear answers on timelines, security, and process for integrating a multi-chain loyalty program.
A standard deployment takes 4-8 weeks from kickoff to mainnet launch. This includes 2 weeks for architecture and smart contract development, 2 weeks for bridge integration and testing, and 2-4 weeks for security audits and final deployment. Complex requirements like custom tokenomics or support for 5+ chains may extend the timeline.
