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.
