Multi-Signature Wallet Contract Penetration

Focused attack simulation targeting signature replay, approval logic, and social engineering vectors in Gnosis Safe and custom multi-sig implementations.

overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 specialists.

We architect and deploy custom smart contracts that power your dApp's core logic. Our development process is built on security-first principles, utilizing OpenZeppelin libraries and comprehensive audit workflows to mitigate risk.

  • Token Standards: ERC-20, ERC-721, ERC-1155, and custom implementations.
  • Protocol Logic: Automated market makers (AMMs), staking pools, vesting schedules, and governance modules.
  • Deliverables: Fully tested code, deployment scripts, and technical documentation.

From a 2-week MVP to a complex DeFi protocol, we deliver contracts that are gas-optimized, upgradeable, and secure by design.

PROVEN PROCESS

Our Penetration Testing Methodology

Our structured, multi-layered approach to multi-signature wallet security goes beyond automated scanners. We simulate real-world attacks to uncover critical vulnerabilities before they can be exploited.

01

Architecture & Design Review

We analyze your multi-sig's access control logic, upgrade mechanisms, and dependency architecture against known attack vectors and industry best practices.

100%
Code Coverage
OWASP
Compliance Checked
02

Manual Code Review & Static Analysis

Expert auditors manually inspect every line of Solidity/Vyper code for logic flaws, gas inefficiencies, and reentrancy risks, supplemented by leading static analysis tools.

Dynamic & Stateful Fuzzing

We execute thousands of randomized transactions to test edge cases, invalid states, and unexpected user behaviors that static analysis can miss.

Economic & Governance Attack Simulation

We model complex attack scenarios including governance takeovers, signature replay attacks, and economic incentives to drain funds or disrupt operations.

Integration & Dependency Testing

We audit the security of interactions with external contracts (oracles, DeFi protocols) and libraries (OpenZeppelin) to prevent supply-chain attacks.

Our Engagement Process

Our structured, four-phase approach ensures a comprehensive security assessment with clear deliverables at every step, minimizing disruption to your development cycle.

01

Discovery & Scoping

We conduct an in-depth technical kickoff to understand your wallet's architecture, governance model, and specific threat vectors. This phase defines the audit scope, timelines, and success criteria.

Multi-Signature Penetration Testing FAQs

Get clear answers on our rigorous security assessment process for multi-signature smart contracts and governance systems.

Our methodology follows a hybrid approach, combining manual expert review with automated analysis. We conduct a three-phase assessment: 1) Architecture Review of the governance model and signer management logic, 2) Code-Level Analysis using static analysis tools and manual line-by-line review for business logic flaws, and 3) Dynamic Testing in a forked mainnet environment to simulate real-world attack vectors like front-running, replay attacks, and signer collusion scenarios. This process is based on the NIST Cybersecurity Framework and OWASP Testing Guide, adapted for smart contracts.
