Interaction-Aware Vulnerability Detection in Smart Contract Bytecodes

IEEE Transactions on Dependable and Secure Computing
The detection of vulnerabilities in smart contracts remains a significant challenge. While numerous tools are available for analyzing smart contracts in source code, only about 1.79% of smart contracts on Ethereum are open-source. For existing tools that

Smart Contract Code Repair Recommendation based on Reinforcement Learning and Multi-metric Optimization

ACM Transactions on Software Engineering and Methodology, 2023
A smart contract is a kind of code deployed on the blockchain that executes automatically once an event triggers a clause in the contract. Since smart contracts involve businesses such as asset transfer, they are more vulnerable to attacks, so it is ...

Smart Contract Languages: a comparative analysis

Future generations computer systems
Smart contracts have played a pivotal role in the evolution of blockchains and Decentralized Applications (DApps). As DApps continue to gain widespread adoption, multiple smart contract languages have been and are being made available to developers, each

Smart (Legal) Contracts, or: Which (Contract) Law for Smart Contracts?

2020
The law applicable to smart contracts is a neglected topic. At times it is even discarded as irrelevant or unnecessary. In fact, many authors claim that smart contracts especially when stored and executed with the help of blockchain technology make contract law and, in fact, the entire legal system obsolete.

Smart Contract

2022
A smart contract is a technology that allows the creation of a negotiation process capable of running independently, without human intervention. This chapter intends to frame the figure of the “smart contract” from a legal point of view. It shows that the smart contract is an advanced tool in the context of a contractual relationship.
