Threat-based security reviews that go beyond code
They have trusted us
Hear from people we worked with
CTO Dean Rubin, Othentic Labs
Dean Rubin, CTO of Othentic Labs, partnered with Composable Security to conduct a thorough security review of the Rewards V2 smart contract module. The project aimed to verify the robustness of a new rewards distribution mechanism integrated with EigenLayer and ensure secure cross-chain operations across multiple Layer 2 networks.
CEO Amadeo Brands, YieldNest
Amadeo Brands, CEO of YieldNest, partnered with us to evaluate the security of their Max Vault integration with the Kernel protocol on BNB Chain. The goal was to ensure safe yield generation and optimize protocol robustness before launch.
Chief Architect Nick Velloff, Braintrust
Nick Velloff came to us for a security review of Braintrust, a decentralized talent network. The primary objective was to ensure the secure expansion of the Braintrust platform onto the Base network, validate integrations with third-party services such as Coinbase Onramp, and secure the wallet infrastructure used by its users.

What is Composable Security? +
We are elite team of security experts specializing in protocols where the contract is only half the system. We tailor our solutions to each client’s unique needs. We reject one-size-fits-all strategies in favor of a personalized, continually evolving service that delivers the highest level of security.
What is smart contract audit? +
A smart contract audit is a comprehensive examination of the code underlying a blockchain-based smart contract. This process involves expert auditors looking for security vulnerabilities, design issues, and efficiency problems. The goal is to ensure the smart contract operates as intended, without any flaws that could lead to security breaches, rug pulls, or hacks.
Smart contract audit is crucial in the blockchain ecosystem to maintain trust and reliability in projects building decentralized applications.
How long do audits take? +
It depends on the complexity of the smart contract. However, on average it takes approximately two weeks.
To learn about how we perform smart contract audits head to this artice.
How much does a security review cost? +
Smart contract audits done by professionals typically cost ~$10000-$30000 for an average project. The price of the audit depends on many factors, but the following have a key impact on the price:
- number of lines of solidity code (nSLOC),
- the complexity of the code,
- documentation quality and code clarity,
- whether the auditors know your protocol and the components you use,
- whether you are using standard implementations or implementing something from scratch,
- the deadline for the audit.
Smart contract audit cost can be slightly minimized if before the audit you use a checklist prepared by us.
What kind of post-audit support do you provide? +
After introducing the changes to the smart contract, we perform a one-time verification to make sure that the recommendations have been introduced in the right way and that the found vulnerabilities do not exist anymore. Afterward, we are always open to assisting our clients in answering all of their questions and helping in solving issues related to security.

Why do smart contracts need to be audited? +
Smart contracts need to be audited to ensure their security and effectiveness. As they are self-executing contracts with the terms directly written into code, any flaws can lead to significant financial losses.
Smart contract audits help identify vulnerabilities before deployment, safeguarding against potential hacks and ensuring the contract functions as intended.
