Custom MPC Threshold Signature Schemes

Design and implementation of bespoke MPC protocols and signature schemes (ECDSA, EdDSA) tailored to your specific security, performance, or regulatory requirements.

overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by experts for your Web3 application.

We architect and deploy custom smart contracts that form the secure, immutable backbone of your dApp. Our development process is built on audited code patterns, OpenZeppelin libraries, and rigorous testing to mitigate risk and ensure reliability from day one.

Deliver a market-ready product in 4-6 weeks with a full-stack MVP, including front-end integration and deployment scripts.

  • Security-First Development: Every contract undergoes static analysis, unit testing, and a formal verification review before deployment to Mainnet or testnets.
  • Protocol Expertise: Specialized development for ERC-20, ERC-721, ERC-1155, staking systems, custom AMMs, and governance modules.
  • Full Lifecycle Support: From initial architecture and Solidity 0.8+ development to deployment, verification, and post-launch monitoring.

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.

02

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.

03

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.

Enhanced User Experience

Design seamless onboarding and transaction flows. Implement social recovery, multi-device management, and intuitive approval interfaces that abstract away MPC complexity for your end-users.

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.
