THE QUANTUM THREAT IS REAL
Why Upgrade Your Multi-Sig Security Now
Post-quantum cryptography is no longer theoretical. With quantum computers advancing, traditional ECDSA signatures securing your multi-sig wallets today are vulnerable to future attacks. Proactive migration is the only defense.
02
Maintain Regulatory Compliance
Stay ahead of emerging financial security mandates. Our upgrade implements FIPS-compliant, audited cryptographic modules, providing documented evidence of due diligence for auditors and regulators concerned with long-term asset security.

Strategic Decision Analysis
Build vs. Buy: Quantum-Resistant Upgrade Paths
Compare the resource investment, risk, and timeline of developing quantum-resistant multi-sig security internally versus partnering with Chainscore Labs.
| Factor | Build In-House | Partner with Chainscore |
|---|---|---|
Time to Implementation | 9-18 months | 6-12 weeks |
Initial Development Cost | $250K - $600K+ | $75K - $200K |
Core Cryptography Expertise | Required (PQC, Lattice) | Provided by our team |
Security Audit & Penetration Testing | External vendor required ($50K+) | Included in service package |
Ongoing Maintenance & Updates | Dedicated internal team | Managed service with optional SLA |
Integration with Existing Wallets | Custom development needed | Pre-built adapters for Ledger, MetaMask |
Post-Quantum Signature Scheme | NIST PQC Finalist selection & implementation | Production-ready implementation of ML-DSA/SPHINCS+ |
Risk of Cryptographic Obsolescence | High (team must track standards) | Low (we manage protocol upgrades) |
Smart Contract Migration Path | Manual, error-prone process | Automated tooling with rollback safety |

Technical & Commercial Questions
Quantum-Resistant Upgrade FAQs
Get clear, specific answers about upgrading your multi-signature wallets to be quantum-resistant. We address common technical, timeline, and security concerns for CTOs and engineering leads.
A standard upgrade for a single multi-sig wallet implementation takes 2-4 weeks from kickoff to mainnet deployment. This includes architecture review, smart contract development, internal testing, and a formal security audit. Complex deployments with multiple signers or custom logic may extend to 6-8 weeks. We provide a detailed project plan with weekly milestones upon engagement.
