Composable Security

About

Composable Security is a smart contract security company based in Kraków, Poland, led by two managing partners who co-authored the Smart Contract Security Verification Standard (SCSVS). It performs threat-based security reviews of smart contracts, off-chain components and AI integrations, for protocols where the contract is only part of the system. Its services are smart contract audits, threat modelling workshops that introduce security by design and raise team awareness, and security consultations that provide expert advice or a second opinion. Its specialisations include EVM projects such as stablecoins, real-world assets, DeFi, tokens, GameFi and staking, liquid staking vaults with their off-chain components, oracles, bridges and custom blockchain implementations, and AI agents and LLM-based products. The audit process runs from initial contact and a tailored proposal through a signed contract, the audit itself, a detailed report, corrections and a retest before final sign-off. Its work page lists each engagement with its date and a link when the report is public, and its blog documents vulnerabilities found in liquid staking, restaking, reward distribution and cross-chain messaging code. Cited engagements involve Base and BNB Chain.
