Every month several important smart contract audits are performed by blockchain security companies like us. It is important to stay up to date with the latest findings in order to learn and improve protection processes. Following we will describe three recent and interesting findings:
A security audit is a process in which a client subjects his or her smart contracts to a review, in which one or more auditors search and document vulnerabilities that may alter the project correct functionality. The main idea of this post is to specify the process of audits, who belongs to them and how the different individuals interact from the moment the client reaches us to the moment we end communication with them.
After our articles Smart Contract Auditing: Human vs. Machine and Auditing Solidity code with Slither we decided to test another static analysis tool from ChainSecurity called Securify.

Smart contract security is a serious problem today. Security flaws, misbehavior, and inefficiency are very expensive when you deploy a Smart Contract to the Blockchain. Companies are especially concerned about their Smart Contract code because once it is run, there is no turning back (they are irreversible) and money can be stuck in the blockchain and lost forever. Thus, to make sure their code is written correctly, these enterprises usually hire well known external auditors (like Coinfabrik) because they know that a problem in their code could cost a lot more money if they skip the audit. Since Smart contracts are used to move, store, distribute funds, errors in smart contract code and design must be minimized. Furthermore, since the appearance of the ICOs in the past few years and with their boom in 2017 and 2018, the smart contract security audits have become one of the most ordered services in the blockchain industry.
