Security Audits

Overview

Sigma Prime delivers comprehensive blockchain security audits combining protocol-level expertise with smart contract review capabilities. As creators of Lighthouse, one of Ethereum's leading consensus clients, our team brings deep understanding of blockchain architecture, cryptography, and distributed systems to identify critical vulnerabilities and provide actionable remediation guidance.

Service Offerings

Protocol & Infrastructure Audits

Security reviews of core blockchain components including consensus mechanisms, P2P networks, cryptographic primitives, virtual machine implementations, L2 sequencers, and full client implementations. Additionally, the building of fuzzing and differential fuzzing tools to help find bugs in protocol implementations.

Smart Contract Audits

In-depth security analysis across multiple ecosystems:

• Solidity - Ethereum and EVM-compatible chains

• Solana - Rust-based Solana programs

• Move - Aptos & Sui smart contracts

• Bitcoin Script & Taproot - Bitcoin applications

• NEAR - Rust smart contracts

• Noir - Aztec Contracts

• Cairo - StarkNet contracts

Cloud Infrastructure Reviews

Security assessment of blockchain node infrastructure, validator deployments, key management systems, API endpoints, and cloud architecture. We evaluate access controls, network security, and operational security practices.

Front-End Security Audits

Review of web3 application front-ends including wallet integrations, transaction signing flows, API security, and client-side vulnerabilities. We assess supply chain risks, dependency security, and user-facing attack vectors.
