Validator Client Audit for Storage Networks | Chainscore Labs

overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built to your exact specifications.

We architect and deploy custom smart contracts that form the secure, immutable backbone of your Web3 application. Our development process ensures your logic is flawlessly translated into code, from ERC-20 tokens and ERC-721 NFTs to complex DeFi protocols and DAO governance systems.

Full Lifecycle Development: From initial specification and architecture design to deployment, verification, and ongoing maintenance.
Security-First Approach: All code undergoes rigorous internal review and is built with OpenZeppelin standards and formal verification best practices.
Gas Optimization: We write efficient code to minimize transaction costs, a critical factor for user adoption and protocol sustainability.

Deploy a secure, audited smart contract suite in as little as 2-4 weeks, accelerating your time-to-market while mitigating critical risks.

Our team specializes in Solidity for EVM chains (Ethereum, Polygon, Arbitrum) and Rust for Solana, delivering contracts that are reliable, upgradeable, and future-proof.

RIGOROUS SECURITY ASSESSMENT

Comprehensive Audit Scope for Validator Clients

Our audit process is engineered for enterprise-grade validator client software, delivering actionable security insights and performance optimizations to ensure network reliability and client trust.

Core Consensus Logic & State Transition

In-depth review of block proposal, attestation, and fork choice logic. We verify correctness against the network's official specification to prevent consensus failures and slashing risks.

Peer-to-Peer (P2P) Network Layer

Security assessment of libp2p implementations, message validation, and peer scoring. We identify vulnerabilities to eclipse attacks, DoS vectors, and ensure robust network propagation.

Msg Validation

Zero DoS

Guarantee

Cryptographic Implementation Review

Line-by-line analysis of BLS signatures, hash functions (SHA256, Keccak), and VDFs. We ensure constant-time execution, side-channel resistance, and compliance with latest standards.

RPC & API Security

Penetration testing on JSON-RPC and REST endpoints. We validate authentication, input sanitization, and rate limiting to protect against injection and unauthorized access.

Frequently Asked Questions on Validator Client Audits

Get clear answers on our rigorous audit process for validator client software, designed to secure the consensus layer of storage networks like Filecoin, Arweave, and beyond.

Our standard audit engagement follows a structured 4-phase process over 3-5 weeks, depending on codebase size and complexity. Phase 1 (1 week): Onboarding & Threat Modeling. Phase 2 (2-3 weeks): In-depth manual review, automated analysis, and adversarial testing. Phase 3 (3-5 days): Report compilation and remediation guidance. Phase 4 (Ongoing): Re-audit of critical fixes. We provide weekly syncs and a dedicated Slack channel for real-time communication.
