CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built for production by Web3 experts.
- Token Systems:
ERC-20,ERC-721,ERC-1155, and custom tokenomics. - DeFi Primitives: Automated Market Makers (AMMs), staking pools, and lending logic.
- Governance & DAOs: On-chain voting, treasury management, and proposal systems.
- Enterprise Logic: Supply chain tracking, credential verification, and asset tokenization.
Every contract undergoes rigorous security audits and formal verification before mainnet deployment, mitigating risks and protecting user funds.
We deliver production-ready contracts in 2-4 weeks, complete with deployment scripts, documentation, and a clear path to audit by leading firms like CertiK or Quantstamp.

The Strategic Choice for Protocol Evolution
Chainscore Migration vs. In-House or Ad-Hoc Approaches
A clear comparison of the cost, risk, and operational impact of different strategies for upgrading your smart contract system.
| Key Factor | In-House Development | Ad-Hoc Freelancer | Chainscore Professional Service |
|---|---|---|---|
Time to Secure Upgrade | 3-6 months | 4-8 weeks | 2-4 weeks |
Security & Audit Quality | Variable (team-dependent) | High Risk (single point) | Enterprise-Grade (multi-audit) |
Total Cost (Year 1) | $250K-$750K+ | $30K-$80K + hidden risks | $50K-$150K (fixed scope) |
Protocol Downtime Risk | High | Very High | Near Zero (proven process) |
Post-Migration Support | Internal team burden | Limited or none | Included (90-day warranty) |
Knowledge Retention | Internal (if team stays) | Lost after engagement | Documented & transferred |
Compliance & Best Practices | Self-defined | Inconsistent | Built-in (upgrade patterns, EIPs) |

A STRUCTURED APPROACH
The Chainscore Migration Process
Our proven, four-phase methodology ensures secure, efficient, and zero-downtime smart contract migrations. We manage the entire lifecycle from risk assessment to final deployment.
01
Phase 1: Discovery & Risk Assessment
We conduct a comprehensive audit of your existing contracts, dependencies, and architecture. This includes a security review, gas analysis, and identification of migration risks and upgrade paths.

Smart Contract Migration FAQs
Get clear, specific answers to the most common questions CTOs and technical leads ask when evaluating a smart contract migration partner.
A standard migration for a DeFi protocol or NFT project takes 2-4 weeks from kickoff to mainnet deployment. This includes audit, testing, and a phased rollout. Complex migrations (e.g., cross-chain state transfer, major architectural changes) can extend to 6-8 weeks. We provide a detailed project plan with weekly milestones during discovery.
