ENTERPRISE-GRADE SECURITY
Our Custom MPC Development Capabilities
We build custom Threshold Signature Scheme (TSS) solutions that eliminate single points of failure for your digital assets. Our engineering focuses on provable security, operational resilience, and seamless integration.
01
Protocol-Agnostic TSS Design
We implement MPC for any blockchain protocol (EVM, Solana, Cosmos, Bitcoin) using battle-tested libraries like GG18/20. Our designs ensure your signing logic is future-proof and portable.

STRATEGIC ADVANTAGES
Why Build a Custom MPC Scheme?
Off-the-shelf MPC solutions impose limitations on security, compliance, and user experience. A custom-built threshold signature scheme gives you precise control over your protocol's most critical asset: its keys.
01
Tailored Security Model
Design a signature scheme that matches your exact threat model and governance requirements. We implement custom signing ceremonies, define participant roles, and enforce business logic at the protocol level for unparalleled security.

Regulatory & Compliance Fit
Integrate specific compliance controls directly into your key management logic. Build support for transaction screening, geofencing, and multi-party approvals that meet institutional and jurisdictional requirements.

Protocol-Specific Optimization
Optimize signature generation and verification for your specific blockchain (EVM, Solana, Cosmos) and use case (staking, bridging, DeFi). Achieve lower latency and gas costs versus generic solutions.

Future-Proof Architecture
Avoid vendor lock-in and gain the ability to upgrade cryptographic primitives (e.g., to post-quantum schemes), add new signers, or modify policies without migrating your entire infrastructure.

Why a custom MPC-TSS is the strategic choice for production systems
Custom Build vs. Standard Library
Choosing between a generic open-source library and a custom-built MPC threshold signature scheme is a critical infrastructure decision. This comparison highlights the operational and security trade-offs for teams building high-assurance custody, staking, or institutional DeFi applications.
| Factor | Generic Open-Source Library | Chainscore Custom MPC-TSS |
|---|---|---|
Time to Production | 6-12+ months | 4-8 weeks |
Initial Security Posture | High risk (unaudited, untested) | Audited, battle-tested architecture |
Protocol & Chain Flexibility | Limited to library support | Custom-built for your target chains (EVM, Cosmos, Solana, etc.) |
Key Management & Rotation | Manual, complex process | Automated, policy-driven workflows |
Signing Latency & Throughput | Variable, often unoptimized | Optimized for <500ms signing, 10k+ TPS |
Ongoing Maintenance Burden | Your team handles upgrades, bugs, security | Managed service with optional 24/7 SLA |
Compliance & Audit Trail | Basic or non-existent | Comprehensive, tamper-evident logs |
Total Cost of Ownership (Year 1) | $250K-$750K+ (engineering, security, ops) | $80K-$200K (predictable service fee) |
Business Risk | High (single point of failure, talent dependency) | Low (professional SLAs, shared security model) |
