PROVEN METHODOLOGY
Our Migration Assurance Framework
A systematic, four-phase approach to de-risk your wallet protocol upgrade. We manage the entire migration lifecycle to ensure zero user funds are lost and zero functionality is broken.
01
Phase 1: Pre-Migration Audit & Strategy
We conduct a comprehensive audit of your existing protocol and dependencies to identify migration risks. This includes dependency mapping, state analysis, and a detailed rollback plan.

Dependency Coverage
< 72 hours
Risk Assessment
02
Phase 2: Isolated Staging & Simulation
Your new protocol is deployed to a forked mainnet environment. We execute automated test suites simulating real user behavior and edge cases before any production touchpoints.

Phase 3: Gradual Canary Deployment
We migrate user cohorts in controlled phases, starting with internal teams, then whitelisted users, monitoring on-chain metrics and off-chain logs for anomalies in real-time.

Strategic Decision Analysis
Managed Migration vs. In-House Patching
A detailed comparison of the cost, risk, and resource allocation between handling a wallet protocol upgrade internally versus partnering with Chainscore for a managed migration.
| Key Factor | In-House Patching | Chainscore Managed Migration |
|---|---|---|
Time to Secure Upgrade | 3-6 months | 4-8 weeks |
Initial Security Risk | High (unaudited custom code) | Negligible (pre-audited patterns) |
Team Resource Drain | 2-3 senior engineers full-time | Your team remains focused on core product |
Upgrade Success Guarantee | None | 100% success SLA |
Post-Migration Support | Your responsibility | 30-day monitoring & incident response |
Total Project Cost | $150K - $300K+ | $50K - $120K |
Protocol Expertise | Requires deep, acquired knowledge | Immediate access to our specialists |
Downtime Risk | Significant (unforeseen issues) | Planned near-zero downtime |

We focus on long-term maintainability. Every contract includes detailed documentation, upgradeability planning via transparent proxies, and post-launch support to ensure your protocol evolves securely.
Technical & Process Questions
Wallet Protocol Migration FAQs
Answers to common questions about our structured approach to upgrading your wallet infrastructure, from initial audit to production deployment.
A standard migration for a single protocol (e.g., from WalletConnect v1 to v2, or a custom EIP-4337 upgrade) takes 2-4 weeks. This includes the audit, development, testing, and deployment phases. Complex multi-chain integrations or custom feature additions can extend this to 6-8 weeks. We provide a detailed project plan with milestones during the initial scoping call.
