PROVEN PROCESS

Our Migration Methodology

A structured, security-first approach to migrating your access control logic across blockchains, minimizing risk and ensuring zero downtime for your users.

Comprehensive Architecture Audit

We perform a deep-dive analysis of your existing smart contract architecture, token standards, and user permissions. This identifies dependencies, security vulnerabilities, and optimization opportunities before a single line of migration code is written.

Initial Report

Multi-Chain Strategy & Blueprint

We design a tailored migration blueprint detailing the target chains (EVM, Solana, Cosmos), bridge selection, phased rollout, and fallback mechanisms. This plan ensures business logic consistency and defines clear success metrics for each phase.

Zero-Downtime

Guarantee

Secure Contract Migration & Deployment

Our engineers execute the migration using verified, audited code patterns. We handle the deployment, configuration, and verification of new access control contracts (e.g., ERC-20/721, custom governance) on all target networks with complete state synchronization.

End-to-End Testing & Simulation

Before mainnet deployment, we run the entire migration process on testnets and private forks. This includes stress testing, simulating user interactions, and validating all cross-chain permission flows to catch edge cases.

A METHODICAL APPROACH

The Chainscore Migration Process

Our proven 4-phase framework ensures a secure, efficient, and zero-downtime migration of your access control logic across EVM chains. We handle the technical complexity so you can focus on growth.

Phase 1: Architecture & Audit

We conduct a comprehensive audit of your existing access control system (e.g., OpenZeppelin Ownable, AccessControl) and design a gas-optimized, upgradeable architecture for multi-chain deployment.

48-72 hours

Initial Audit

100% Coverage

Logic Review

Phase 2: Smart Contract Development

Our engineers develop and harden the migration contracts using Solidity 0.8+ and OpenZeppelin libraries. Includes custom logic for cross-chain role synchronization and pause mechanisms.

1-2 weeks

Development Time

Security Standard

Phase 3: Testing & Simulation

We deploy to testnets (Sepolia, Holesky) and run exhaustive simulations using Foundry and Hardhat. This includes stress tests, role migration dry-runs, and failure scenario analysis.
