Quantum-Resistant Multi-Signature Development

Deploy a future-proof transition strategy with our dual-signature approach, combining ECDSA with PQC signatures to maintain compatibility with existing infrastructure while securing against future quantum threats.

Our Solidity libraries are engineered for minimal on-chain overhead, reducing the computational cost of quantum-safe verification by up to 40% compared to naive implementations, keeping transaction fees predictable.

Configure complex approval workflows with our on-chain policy module. Set M-of-N thresholds, time-locks, and role-based permissions that are enforced by the quantum-resistant signature scheme, ensuring flexible yet secure governance.

Every kit undergoes rigorous security audits following our standardized process, which includes formal verification of cryptographic primitives and penetration testing to ensure the implementation matches the mathematical security proofs.

Accelerate integration with our client-side SDKs for web and mobile. Includes support for EVM chains (Ethereum, Polygon, Arbitrum) and seamless wallet connectivity (MetaMask, WalletConnect) for a smooth user experience.

Protect high-value wallets, treasury management systems, and institutional custody solutions from future quantum attacks. Our multi-sig solutions use NIST-standardized post-quantum cryptography (PQC) algorithms.

Retrofitting security is exponentially more expensive and disruptive than building it in from the start. Our development integrates quantum resistance at the protocol layer, eliminating future migration risks.

Financial regulators and institutional partners are beginning to mandate quantum-readiness. Our audited solutions provide the documentation and cryptographic assurance needed for compliance.

Differentiate your protocol or custodial service by offering clients the gold standard in long-term security. Demonstrating quantum preparedness builds unparalleled trust with enterprise partners.

We begin with a comprehensive security assessment, mapping out attack vectors and designing a multi-layered architecture. This includes selecting optimal post-quantum cryptographic algorithms (e.g., CRYSTALS-Dilithium, Falcon) and defining key management policies.

Implementation of custom, gas-optimized multi-signature logic using Solidity 0.8+ and OpenZeppelin libraries. We integrate post-quantum signature verification modules and ensure backward compatibility with existing ECDSA wallets during the transition period.

Every line of code undergoes multi-stage review: automated analysis, internal peer review, and a final audit by a leading third-party security firm. We provide a public audit report to build trust with your users.

Seamless integration with your existing front-end and back-end systems. We conduct exhaustive testing including unit tests, integration tests, and simulated quantum attack scenarios on testnets before mainnet deployment.

Managed mainnet deployment with a secure, audited key generation and distribution ceremony for initial signers. We ensure proper configuration of transaction thresholds and provide comprehensive deployment documentation.

Post-deployment, we provide monitoring dashboards for transaction activity and security alerts. We offer ongoing support for upgrades, including integration of new NIST-standardized PQC algorithms as they emerge.
