About

Sigma Prime is a blockchain security and engineering company that states it was born and is headquartered in Sydney, Australia. It audits off-chain code, zero-knowledge systems, blockchain infrastructure and smart contracts. Its security services include infrastructure audits of cloud, CI/CD, signers and validators, blockchain protocol audits of consensus, clients, rollups and layer 2 networks, smart contract audits, rolling commit reviews for actively developed codebases, an integrated security engineer offer, frontend application reviews of dApps, wallets and APIs, and security training. A smart contract audit is a manual line-by-line review of Solidity, Vyper or Rust contracts, with Move and Cairo also listed, usually carried out in pairs, with a second engineer independently checking findings. Static analysis (Slither, Mythril, custom Semgrep rules), invariant fuzzing (Foundry, Echidna, Halmos) and symbolic execution run alongside the manual work, and reports include reproducible findings with severity and remediation guidance. Sigma Prime also develops Lighthouse, an open-source Rust Ethereum consensus client, Anchor, a Rust SSV implementation for distributed validators, and the Bombora block builder, and publishes its public audits on GitHub.
