Smart contracts and security basics

Abstract

Currently, one of the most vital issues concerns dealing with smart contracts is security. Concerns over inefficiency, security, and fraud are grounded, and ignoring them when using the blockchain network to create smart contracts can result in extremely high additional costs. This article covers the most common tools for auditing smart contracts. The purpose of this article is to compare the most popular software tools to analyze smart contract security. For this purpose, the following types of smart contract vulnerabilities were investigated. This article provides examples of the major smart contract vulnerabilities, and given the relevance of digital agreements and the catastrophic consequences of errors, recommendations have been offered to redress smart contract vulnerabilities.
