DELIVERABLES
Business Outcomes: Secure, Governed Upgrades
Our migration service delivers more than just code deployment. We provide a structured governance framework and security-first process that ensures your protocol evolves without risk.
01
Governance-Enabled Migration Module
We deliver a custom CosmWasm migration module that integrates with your DAO's voting system (e.g., DAODAO, cw3-flex-multisig). This enables token-holder or multi-sig controlled upgrades, ensuring community-led evolution.

Cost & Risk Analysis
Build vs. Buy: In-House vs. Chainscore Migration
A detailed comparison of the time, cost, and risk profile for migrating CosmWasm contracts internally versus partnering with Chainscore's specialized team.
| Key Factor | Build In-House | Chainscore Migration Service |
|---|---|---|
Time to Production | 4-9 months | 4-8 weeks |
Initial Security Risk | High (unaudited, custom tooling) | Low (pre-audited patterns, battle-tested tools) |
Team Composition Required | 2-3 Senior Rust/CosmWasm Devs | Your existing team + our dedicated migration engineers |
Total First-Year Cost | $180K - $400K+ (salaries, tools, audits) | $50K - $150K (fixed-scope engagement) |
Post-Migration Support | Internal team responsibility | Optional SLA with 24/7 monitoring & incident response |
Guarantee on Delivery | None (internal project risk) | Fixed timeline & budget with success-based milestones |
Access to Expertise | Limited to hired team's knowledge | Direct access to team with 50+ CosmWasm migrations completed |

STRUCTURED FOR SUCCESS
Our Proven 4-Phase Migration Process
We execute CosmWasm migrations with a predictable, transparent methodology. This phased approach ensures zero downtime, eliminates upgrade risks, and delivers a production-ready contract on schedule.
01
Phase 1: Audit & Analysis
We conduct a comprehensive security and code review of your existing CosmWasm contract. This includes identifying migration blockers, gas inefficiencies, and security vulnerabilities to create a detailed migration blueprint.
Key Deliverable: A prioritized migration report with security findings and upgrade roadmap.
