overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
Deliver a secure, functional MVP in as little as 2-4 weeks, not months.
Our full-service development includes:
- Gas-optimized logic for
ERC-20,ERC-721, and custom token standards. - Upgradeable architecture using transparent proxies for seamless future improvements.
- Comprehensive testing suite with 95%+ coverage and integration with
HardhatorFoundry. - Deployment & verification on your target chain (Ethereum, Polygon, Solana, etc.).
We focus on security-first development. Every contract undergoes internal review against common vulnerabilities before we recommend third-party audits from firms like CertiK or Quantstamp, ensuring your protocol's integrity and user trust.

Smart Contract Upgrade & Migration
Chainscore vs. In-House or Generic Dev Shop
A clear comparison of approaches for managing smart contract evolution, highlighting the trade-offs between time, cost, security, and control.
| Key Factor | In-House Team | Generic Dev Shop | Chainscore |
|---|---|---|---|
Time to First Secure Upgrade | 3-6 months | 6-12 weeks | 2-4 weeks |
Upgrade Pattern Expertise | Self-taught risk | Variable, often basic | Proven (UUPS, Beacon, Diamond) |
Pre-Migration Security Audit | Optional extra cost | Often outsourced separately | Included in core service |
Post-Deployment Monitoring | Your responsibility | Rarely included | Included with 24/7 alerting |
Gas Optimization for Migrations | Trial and error | Basic estimates | Pre-simulated & cost-optimized |
Total Cost (First Major Upgrade) | $80K-$200K+ | $30K-$80K | $25K-$60K |
Long-Term Upgrade Maintenance | High (ongoing team cost) | None (project ends) | Optional SLA available |
Protocol-Specific Knowledge | Built from scratch | Limited to common standards | Deep (ERC-20/721, DeFi, L2s) |

PROVEN PROCESS
Our 4-Phase Migration Methodology
A systematic, security-first approach to upgrading live contracts, minimizing risk and ensuring zero downtime for your users.
01
Phase 1: Audit & Strategy
We conduct a comprehensive audit of your existing contracts, dependencies, and state. This phase defines the migration scope, selects the optimal upgrade pattern (Transparent/UUPS/Beacon), and creates a detailed rollback plan.

Code Coverage Audit
3-5 Days
Strategy Finalization
02
Phase 2: Development & Simulation
Our engineers build the new contract logic using established patterns (OpenZeppelin Upgrades). We run extensive simulations in a forked mainnet environment to test all migration paths and edge cases before any live deployment.

Phase 3: Staged Deployment
We execute the migration using a phased, canary-style rollout. This includes deploying the proxy/beacon upgrade, verifying storage layout compatibility, and migrating user state in controlled batches to monitor system stability.

Phase 4: Verification & Monitoring
Post-migration, we verify all contract functions, user balances, and permissions. We provide 72-hour enhanced monitoring with real-time alerts and a final security review to confirm the upgrade's success and integrity.

Technical & Commercial Questions
Smart Contract Upgrade & Migration FAQ
Answers to common questions from CTOs and engineering leads about our upgrade and migration methodology, security, and delivery.
We follow a structured 4-phase process: 1) Audit & Planning (1 week) – comprehensive code review and migration strategy. 2) Development & Testing (2-3 weeks) – building upgrade modules and rigorous unit/integration testing. 3) Security Review (1 week) – internal audit and formal verification. 4) Deployment & Verification (3-5 days) – mainnet deployment with on-chain verification. Most standard upgrades are delivered in 4-6 weeks from kickoff.
