CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Token Standards:
ERC-20,ERC-721,ERC-1155, and custom implementations. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, staking mechanisms.
- Governance Systems: DAO frameworks with voting, treasury management, and proposal execution.
- Enterprise Logic: Custom business rules, access control, and multi-signature workflows.
We deliver a fully tested, gas-optimized contract suite in 2-4 weeks, ready for mainnet deployment and third-party audit.

PROVEN PROCESS
Our Migration Framework
A systematic, security-first approach to CosmWasm contract upgrades. We deliver predictable, zero-downtime migrations that protect your protocol's integrity and user funds.
01
Migration Strategy & Planning
We architect a detailed migration plan covering state transition, data integrity, and user communication. This includes dependency analysis, rollback procedures, and governance coordination for a seamless upgrade.

AVOID DOWNTIME & DATA LOSS
Why a Structured Migration Strategy Matters
Ad-hoc contract upgrades risk protocol integrity and user trust. A structured, audited migration process ensures continuity, security, and a seamless user experience.
03
Security-First Audit Trail
Every migration plan undergoes a full security review, including upgrade handler logic and post-migration state checks, to prevent introducing vulnerabilities.
04
Governance & Multi-Sig Coordination
We design and execute the proposal and voting flow, integrating with Cosmos SDK governance or custom multi-sig setups for secure, permissioned upgrade execution.
05
Rollback & Emergency Procedures
We deliver a documented rollback plan and emergency pause mechanisms, providing a safety net in case of unforeseen issues during the live migration.
06
Post-Migration Verification
Our service includes automated testing suites and on-chain verification to confirm the new contract behaves as intended, ensuring a successful transition.
From Assessment to Production
Typical CosmWasm Migration Timeline
A phased breakdown of a standard contract migration project, from initial code analysis to post-deployment monitoring.
| Phase & Key Activities | Duration | Chainscore Deliverables | Client Responsibilities |
|---|---|---|---|
Phase 1: Audit & Analysis • Security & logic review of existing contracts • Migration feasibility assessment • Gas optimization analysis | 1-2 weeks | Comprehensive audit report Risk mitigation plan Migration architecture proposal | Provide access to source code Share project requirements & goals |
Phase 2: Migration Development • Refactoring code to CosmWasm 1.x • Implementing new features/upgrades • Unit & integration testing | 3-5 weeks | Migrated, audited contract code Test suite with >95% coverage Deployment scripts | Review progress in weekly syncs Provide testnet credentials Clarify business logic |
Phase 3: Testing & Validation • Multi-chain testnet deployment • End-to-end functionality tests • Security re-audit of final code | 1-2 weeks | Testnet deployment on target chains Final audit report & certificate Performance benchmark data | Participate in UAT (User Acceptance Testing) Approve final contract version |
Phase 4: Production Deployment • Mainnet deployment & verification • Liquidity/state migration execution • Post-deployment monitoring setup | 1 week | Live mainnet contracts Verification on block explorers Initial 72-hour monitoring | Execute governance proposals (if needed) Provide mainnet deployer keys Confirm migration success |
Phase 5: Support & Handoff • Documentation & knowledge transfer • Optional SLA for ongoing support • Performance review | 1 week | Technical documentation Post-migration review report Optional support contract | Internal team training Plan for future upgrades |

Your Migration Questions, Answered
CosmWasm Migration FAQs
Get clear, technical answers to the most common questions about migrating smart contracts to CosmWasm. Based on our experience with 30+ successful migrations.
A standard migration for a single, well-documented contract takes 2-4 weeks from codebase handoff to testnet deployment. Complex protocols with multiple interdependent contracts, custom logic, or significant refactoring needs typically require 6-10 weeks. We provide a detailed project plan with milestones after the initial technical assessment.
