overview
SECURE FOUNDATIONS
Smart Contract Development
Production-ready smart contracts built for security, gas efficiency, and seamless integration.
Deliver a secure, gas-optimized MVP in as little as 2-4 weeks, with a clear path to mainnet deployment.
Our full-service development includes:
- Custom logic for
ERC-20,ERC-721,ERC-1155, and bespoke protocols. - Gas optimization reviews to minimize user transaction costs.
- Integration-ready code with comprehensive documentation and test suites.
- Pre-audit preparation, structuring code for seamless review by top security firms.
We focus on long-term maintainability. Every contract is built with upgradeability patterns like Transparent Proxy or UUPS, modular architecture for easy feature updates, and full deployment scripts for any EVM-compatible chain.

Managed Service vs. In-House Migration
A quantitative comparison of the total effort, risk exposure, and resource allocation required for migrating your decentralized identity (DID) system during a major chain upgrade.
| Migration Factor | In-House Team | Chainscore Managed Service |
|---|---|---|
Time to Completion | 3-6 months | 4-8 weeks |
Core Team Effort | 2-3 senior engineers full-time | 1 technical lead part-time |
Security Audit Required | Yes ($30K-$100K+) | Included |
Protocol Expertise | Must be developed internally | Pre-built for Ethereum, Polygon, Solana |
Post-Migration Support | Your responsibility | 12-month SLA included |
Risk of Downtime/Data Loss | High (unaudited code) | Negligible (proven migration framework) |
Total Project Cost | $200K-$500K+ | Starts at $75K |
Guaranteed Success | No | Yes (contractual) |

PROVEN METHODOLOGY
Our Phased, Zero-Downtime Migration Process
We execute DID migrations for protocol upgrades with surgical precision, ensuring no service disruption for your users. Our battle-tested process isolates risk and guarantees data integrity at every stage.
01
Phase 1: Audit & Strategy
We conduct a full audit of your existing DID implementation and dependencies. Our team delivers a detailed migration blueprint with rollback procedures, risk assessment, and a phased rollout schedule.
48-72 hours
Initial Audit

Phase 2: Parallel Environment
We deploy and validate the new DID system (e.g., W3C Decentralized Identifiers v1.0, Verifiable Credentials) in a production-mirrored staging environment. This allows for exhaustive testing without touching live user data.

Phase 3: Dual-Write & Validation
We implement a dual-write mechanism where new user actions are recorded in both legacy and new systems. This creates a verifiable audit trail and allows for real-time data consistency checks before cutover.

Phase 4: Gradual Traffic Cutover
Using feature flags and canary deployments, we redirect a small percentage of user traffic to the new DID system. We monitor performance and user experience metrics, scaling up only after confirming stability.

DID Migration Service: Frequently Asked Questions
Technical answers for teams planning a decentralized identity system upgrade. Based on our experience migrating 50+ projects to new DID standards.
Our standard DID migration from a legacy system (e.g., v0.1, custom registry) to a modern standard (e.g., W3C DID Core, ERC-725/ERC-734) takes 2-4 weeks. This includes audit, smart contract deployment, data migration, and integration testing. Complex migrations involving multiple identity types or cross-chain attestations may extend to 6-8 weeks. We provide a detailed project plan within the first 48 hours of engagement.
