Embodiment Construction

[0026] In view of this, the present invention provides a method and device for smart contract vulnerability detection to improve the developer's development efficiency and enhance the code Security, reducing developer time and investment costs.

[0027] The technical solution of the present invention is as follows: a method for smart contract vulnerability detection, the method comprising uploading smart contract code files;

[0028] Correspondingly, the smart contract code file is in a .sol file format.

[0029] Such as figure 1 Shown is the function implementation topology diagram of the smart contract vulnerability detection method in this embodiment. Specifically, the .sol smart contract file to be audited is determined by the local client and uploaded to the server.

[0030] In this embodiment, the smart contract vulnerability detection method is an engine made through a series of technical detections for the smart contract written in Solidity and running on the Ethereu...

Abstract

The invention provides an intelligent contract vulnerability detection method and system, and belongs to the technical field of intelligent contracts. The method comprises the steps of uploading an intelligent contract code file; enabling the server side to execute intelligent contract vulnerability detection on the intelligent contract code file and returns an intelligent contract vulnerability detection result; wherein the smart contract vulnerability comprises a reentrant attack vulnerability; and one or more of integer value overflow vulnerability, conditional logic risk verification, access control authority risk verification, return value risk verification, random number misuse risk verification, execution sequence dependent vulnerability, timestamp dependent vulnerability, short address attack vulnerability, platform interface misuse vulnerability, denial of service attack detection vulnerability and multi-signature contract vulnerability. According to the method, the intelligent contract program file is uploaded to the server side through the client side to execute automatic detection of the vulnerability, so that manpower is liberated, detection is convenient, the speed ishigh, and the accuracy is high.

Description

technical field [0001] The invention relates to the technical field of smart contracts, in particular to a method and system for detecting smart contract vulnerabilities. Background technique [0002] Ethereum (Ethereum) is an open source public blockchain platform, which has the characteristics of decentralization, consensus, and distributed ledgers of the blockchain. It provides all developers with a smart contract solution platform based on the Solidity language. It provides various modules for users to create smart contracts for their own projects. [0003] A smart contract is a computer protocol designed to communicate, verify or enforce contracts in an informational manner. Smart contracts allow for trusted transactions without third parties, which are traceable and irreversible. The purpose of smart contracts is to provide a method of security superior to traditional contracts and to reduce other transaction costs associated with contracts. [0004] At present, the...
