Core Architectural Components We Deliver
We design and implement the core infrastructure for your cross-chain custody network, ensuring security, scalability, and seamless interoperability from day one.
01
Multi-Party Computation (MPC) Node Infrastructure
Deploy a distributed network of MPC nodes using industry-standard libraries (GG20/GG18) for threshold signature generation. We implement geographic distribution, automated key refresh, and Byzantine fault tolerance to eliminate single points of failure.

Business Outcomes of a Distributed MPC Network
Our multi-party computation (MPC) network design delivers tangible operational and financial results, moving beyond theoretical security to measurable business advantage.
01
Eliminate Single Points of Failure
Distribute signing authority across multiple, geographically separate nodes. No single entity holds a complete private key, removing the risk of catastrophic loss from a single breach or insider threat.

Reduce Operational Overhead by 70%
Automate key generation, rotation, and transaction signing workflows. Replace manual, error-prone processes with programmable policies, freeing your team from daily key management tasks.

Architectural Comparison
MPC Network vs. Traditional Custody Models
A technical breakdown of how our distributed MPC network design fundamentally differs from legacy single-provider or in-house custody solutions.
| Architectural Factor | Traditional Custody (Single-Provider) | In-House MPC | Chainscore MPC Network |
|---|---|---|---|
Key Management Model | Centralized (Provider Vault) | Distributed (Your Infrastructure) | Federated (Multi-Cloud, Multi-Region) |
Single Point of Failure | High (Provider Outage) | Medium (Your Infrastructure) | None (Byzantine Fault Tolerant) |
Geographic Resilience | Limited to Provider DCs | Your Responsibility | Built-in (3+ Global Regions) |
Time to Secure Deployment | 4-8 weeks (Onboarding) | 6-12 months (R&D + Build) | 2-4 weeks (Integration) |
Cryptographic Security | HSM-based (SLOW) | MPC Library (Varies) | Threshold ECDSA (Audited, SLOW10) |
Cross-Chain Native Support | Limited / Bridged | Custom Development Required | Native (EVM, Solana, Cosmos SDK, Move) |
Operational Cost (Year 1) | $100K+ (Fees + Ops) | $250K-$500K (Team + Infra) | $50K-$150K (SLA-based) |
Disaster Recovery RTO | 24-72 hours | Defined by Your Team | < 4 hours (SLA-backed) |
Compliance & Audit Trail | Provider's System | Your Responsibility | Unified, Immutable Ledger |
Team Expertise Required | Low (API Integration) | Very High (Cryptography, DevOps) | Low (SDK/API Integration) |

Technical & Commercial Insights
Frequently Asked Questions on MPC Custody Networks
Get clear, specific answers to the most common questions CTOs and founders ask when evaluating a cross-chain MPC custody solution.
A standard deployment for a production-ready, cross-chain MPC custody network takes 4-8 weeks. This includes the architecture design, smart contract development, key management system integration, and security audit preparation. For more complex integrations with existing treasury systems or novel signing schemes, timelines extend to 10-12 weeks. We provide a detailed project plan within the first week of engagement.
