overview
CORE SERVICE
Smart Contract Development
Secure, gas-optimized smart contracts built for production from day one.
- Security-First Architecture: Every contract undergoes rigorous internal review using
SlitherandMythXbefore deployment. We implement multi-sig controls and timelocks as standard for critical functions. - Gas Optimization: We specialize in minimizing on-chain costs, achieving up to 40% gas reduction through efficient storage patterns and bytecode optimization.
- Full Lifecycle Support: From initial spec to mainnet deployment and post-launch upgrades, we manage the entire contract lifecycle with 99.9% uptime SLAs.
We don't just write code; we engineer resilient systems that protect your assets and scale with your user base.

The Strategic Choice for Your Bridge
Build vs. Buy vs. Our Custom SDK
Compare the strategic, technical, and financial implications of developing a cross-chain bridge in-house, using a generic third-party SDK, or partnering with Chainscore for a custom, production-ready solution.
| Key Factor | Build In-House | Generic Third-Party SDK | Chainscore Custom SDK |
|---|---|---|---|
Time to Production Launch | 6-12+ months | 2-4 months | 4-8 weeks |
Initial Development Cost | $250K - $750K+ | $0 - $50K (license) | $80K - $200K |
Security Posture & Audit Burden | High (Your team's responsibility) | Medium (Shared risk, limited audits) | Low (Pre-audited core, custom audit included) |
Protocol & Chain Coverage | Custom, requires ongoing R&D | Fixed, limited to vendor roadmap | Tailored to your roadmap, future-proof |
Gas Optimization & Fee Management | Built from scratch | One-size-fits-all | Custom logic for your tokenomics |
Ongoing Maintenance & Upgrades | Full internal team required | Dependent on vendor releases | Optional SLA with 24/7 monitoring |
Custom Features (e.g., staking, governance) | Fully customizable | Highly limited or impossible | Designed and integrated from day one |
Total Cost of Ownership (Year 1) | $400K - $1M+ | $50K - $150K+ (license + dev) | $100K - $250K (all-inclusive) |
Strategic Control & IP Ownership | Full ownership | Vendor lock-in, no IP | Full IP ownership of custom layer |

Frequently Asked Questions
Get clear answers on development timelines, security, and support for your mobile cross-chain bridge project.
A production-ready, audited SDK for 2-3 major chains (e.g., Ethereum, Polygon, BSC) typically takes 4-6 weeks from kickoff to deployment. This includes architecture, core development, security audits, and integration testing. Adding support for additional chains or complex features like gasless transactions can extend the timeline by 1-2 weeks per chain.
