CodeNet: Code-Targeted Convolutional Neural Network Architecture for Smart Contract Vulnerability Detection

open access: yesIEEE Access, 2022
A smart contract is a computer program which is automatically executed with some conditional statements such as “if/then”. Since smart contracts can include some vulnerable program codes, smart contract exploit was recently highlighted as ...

Smart Contract Upgradeability on the Ethereum Blockchain Platform: An Exploratory Study [PDF]

open access: yesarXiv, 2023
Context: Smart contracts are computerized self-executing contracts that contain clauses, which are enforced once certain conditions are met. Smart contracts are immutable by design and cannot be modified once deployed, which ensures trustlessness. Despite smart contracts' immutability benefits, upgrading contract code is still necessary for bug fixes ...

DEFECTCHECKER: Automated Smart Contract Defect Detection by Analyzing EVM Bytecode [PDF]

open access: yes, 2020
Smart contracts are Turing-complete programs running on the blockchain. They are immutable and cannot be modified, even when bugs are detected. Therefore, ensuring smart contracts are bug-free and well-designed before deploying them to the blockchain is extremely important. A contract defect is an error, flaw or fault in a smart contract that causes it

Probabilistic Framework For Loss Distribution Of Smart Contract Risk [PDF]

open access: yesarXiv, 2021
Smart contract risk can be defined as a financial risk of loss due to cyber attacks on or contagious failures of smart contracts. Its quantification is of paramount importance to technology platform providers as well as companies and individuals when considering the deployment of this new technology. That is why, as our primary contribution, we propose
