CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts for your protocol or dApp.
- Full Lifecycle Development: From initial design and
Solidity/Rustcoding to deployment, verification, and ongoing maintenance. - Security-First Approach: All code undergoes internal audits and follows
OpenZeppelinstandards before we recommend third-party review. - Gas Optimization: We write efficient code to minimize transaction costs for your users, a critical factor for adoption.
- Integration Ready: Contracts are built for seamless interaction with frontends, oracles, and other protocol layers.
Deliver a secure, auditable, and gas-efficient foundation. We handle the complex backend logic so you can focus on product and growth.

PROVEN PROCESS
Our Migration Methodology: Zero-Downtime Execution
A systematic, battle-tested approach to migrate your staking infrastructure without service interruption or loss of rewards. We ensure validator uptime, fund security, and protocol compliance throughout the transition.
01
Phase 1: Architecture & Risk Assessment
We conduct a full audit of your current staking stack—from node clients and key management to slashing protection—to identify migration risks and dependencies. This includes a security review and a detailed rollback plan.

Phase 2: Staged Validator Migration
We migrate validators in controlled batches, not all at once. This minimizes exposure, allows for real-time monitoring of each batch's performance on the new system, and ensures rewards continue accruing.

Phase 3: Live Cutover & Monitoring
Final migration of core services (RPC endpoints, APIs) with comprehensive health checks. We provide 24/7 monitoring dashboards for your team, tracking validator effectiveness, block proposals, and slashing conditions.

TANGIBLE ROI
Business Outcomes: Beyond Technical Debt Reduction
Migrating your legacy staking system isn't just about fixing old code. It's a strategic investment that unlocks new revenue streams, strengthens security, and accelerates your roadmap. Here's what you gain.
01
Unlock New Revenue Streams
Deploy flexible staking models (liquid, restaking, validator services) to capture market demand. We build with composability in mind, enabling integration with DeFi protocols to generate additional yield for your treasury and users.

The Infrastructure Trade-Off
Legacy In-House vs. Modern API-Driven Staking
A direct comparison of the operational, financial, and technical burdens of maintaining legacy staking systems versus adopting a modern, API-driven solution.
| Key Factor | Legacy In-House System | Chainscore Migration |
|---|---|---|
Time to Upgrade & Launch | 6-12 months | 4-8 weeks |
Upfront Development Cost | $200K - $500K+ | $0 (No rebuild required) |
Security & Audit Burden | High (Your team's responsibility) | Inherited (Pre-audited, battle-tested protocols) |
Ongoing DevOps & Node Ops | Full-time team required | Fully managed (Zero ops for you) |
Protocol Upgrade Agility | Months of redevelopment | Instant via API (We handle upgrades) |
Multi-Chain Support | Custom integration per chain | Native support for 15+ chains |
Uptime & Slashing Risk | Your liability (Single points of failure) | 99.9% SLA with slashing insurance |
Total Cost of Ownership (Year 1) | $300K - $750K+ | $50K - $150K (Predictable subscription) |

Legacy Staking Migration: Key Questions for CTOs
Critical questions to evaluate when migrating from a legacy staking system to a modern, scalable architecture. Based on our experience with 50+ protocol migrations.
Standard migrations are delivered in 2-4 weeks with a fixed-price model ranging from $25K to $75K. This includes architecture review, smart contract migration, testing, and deployment. Complex migrations with custom slashing logic or multi-chain support require a custom quote, typically $80K-$150K. We provide a detailed project plan and cost breakdown within 48 hours of a technical discovery call.
