An Opcode-Based Vulnerability Detection of Smart Contracts

Aiming at the problem of insufficient technology for detecting smart contract vulnerabilities and lack improvement certain detection tools, a method expansion internal module Mythril is proposed. Since not yet mature there are in contracts, vulnerability particularly important. tool covers most types vulnerabilities, its accuracy rate also highest. In order to ensure effect detection, this paper proposes Mythril, which realizes operation automatic analysis when performing by improving efficiency simplifying opcodes while analyzing them. The comparison experimental results shows that proposed more suitable improved, with an average 94.07%. It performs better provides effective guarantee security reliability has important application value research significance.
