Smart Contract Audits
Decentralized Appication Security
Decentralized applications are prominent high-value targets for cybersecurity attacks with particular threat models and attack surfaces. Oak Security exists to solve the problem faced by decentralized application developers to secure their creations throughout the software lifecycle, from early planning to daily operations.
Ethereum is the biggest platform for decentralized finance. Oak Security team members have been involved in Ethereum smart contract auditing since 2017 and have collected vast experience in anything from DeFi protocols to complex L2 solutions.
We are constantly investing in new talent and research on emerging platforms yet to be covered by a comprehensive security ecosystem. If you are working on more recent additions to the smart contract work, such as Cardano or Solana, we are able to help you secure your applications.
Blockchain security begins at the protocol level. With modular platforms allowing the development of application-specific blockchains and the emergence of blockchain interoperability, security reviews must be extended to these layers.
Blockchains used to silos but have recently started to communicate with each other. The Oak security team has been involved with blockchain bridges since the early days, in research, development, and, most importantly, security.
