PROVEN METHODOLOGY
Our Migration Framework
A systematic, security-first approach to migrating your existing DeFi, NFT, or enterprise application to a new privacy protocol. We minimize downtime, eliminate data loss, and ensure full compatibility.
01
Discovery & Architecture Audit
We conduct a comprehensive analysis of your current smart contracts, tokenomics, and user flows to identify migration risks and dependencies. This creates a detailed migration blueprint.

EXPERT MIGRATION
Why Migrate with Chainscore
Move from Tornado Cash, Aztec, or other deprecated privacy protocols with zero downtime and full compliance. Our battle-tested migration framework ensures your application's core logic and user assets are preserved.
01
Zero-Downtime Migration
We execute a phased, on-chain migration strategy that keeps your dApp live. Users continue transacting while we migrate liquidity and state in the background, eliminating service interruption.

Technical & Commercial Questions
Privacy Protocol Migration FAQs
Common questions from CTOs and technical founders about migrating from deprecated privacy protocols to secure, audited alternatives.
A standard migration to a compliant privacy protocol like Aztec, ZK-proof systems, or custom implementations takes 2-4 weeks from audit to mainnet deployment. This includes threat modeling, smart contract development, security audits, and integration testing. Complex protocols with custom privacy-preserving logic may extend to 6-8 weeks.
