DELIVERABLES & GUARANTEES
Business Outcomes: Secure, Verifiable Compliance
Our migration service delivers more than just code. We provide a production-ready, auditable compliance layer that reduces your operational risk and accelerates time-to-market.
01
Zero-Risk Logic Migration
We guarantee the functional equivalence of your migrated compliance rules. Every KYC check, AML flag, and jurisdiction filter is validated against your legacy system's outputs before deployment.

Architectural Comparison
Client-Side Scripts vs. On-Chain Compliance Logic
A technical breakdown comparing the traditional, vulnerable approach of client-side validation with the secure, verifiable standard of on-chain logic.
| Compliance Factor | Client-Side Scripts (Legacy) | On-Chain Logic (Chainscore) |
|---|---|---|
Verification Integrity | ||
Attack Surface | High (Frontend manipulation) | Low (Immutable code) |
Audit Trail | None (Off-chain) | Complete (On-chain ledger) |
Regulatory Proof | Impossible to provide | Automatically generated |
Time to Remediate Flaw | Days (Requires redeploy) | Hours (Logic update only) |
Implementation Complexity | Medium (Custom UI logic) | Low (Standardized modules) |
Typical Annual Cost | $50K-$200K+ (Security incidents) | $25K-$75K (Managed service) |

FOUNDATION
Blockchain Infrastructure & Node Management
Enterprise-grade node infrastructure with 99.9% uptime SLAs, multi-cloud redundancy, and real-time monitoring.
We eliminate the operational burden of running your own nodes. Our managed infrastructure provides dedicated, high-performance RPC endpoints for Ethereum, Polygon, Arbitrum, and other major L1/L2 networks, ensuring your application never misses a block.
- Guaranteed Reliability: 99.9% uptime SLA with multi-cloud redundancy across AWS, GCP, and bare-metal providers.
- Real-Time Monitoring: Proactive health checks, performance dashboards, and instant alerting for chain reorganizations or latency spikes.
- Enhanced Performance: Access to archival data,
debugandtraceAPIs, and optimized gas estimation for complex transactions.
Focus on building your product, not maintaining infrastructure. We handle node upgrades, security patches, and scaling so you can deploy with confidence.

Frequently Asked Questions
Get clear, specific answers about migrating your compliance logic from backend to on-chain smart contracts.
A standard migration for a single protocol or DApp takes 3-6 weeks, from initial audit to final deployment and testing. This includes: 1-week discovery & audit, 2-4 weeks of development & unit testing, and 1 week of integration testing and mainnet deployment. Complex multi-protocol migrations or those requiring custom rule engines can extend to 8-12 weeks. We provide a detailed project plan with milestones within the first 3 days of engagement.
