Risk Assessment of Smart Contracts

Abstract

In cryptocurrency market, smart contracts are used to transfer billions of dollars, and risk analysis of these contracts is crucial for ensuring their security in this rapidly evolving digital landscape. This study uses eight key risk criteria of smart contracts from the literature. The importance of these criteria was determined through a survey of experts by applying neutrosophic PIPRECIA method to weigh experts' opinion significance based on their knowledge and experiences. This leads to improve the credibility of the risk analysis process. The risk of nine specific smart contracts was then evaluated by applying a hybrid of the DEMATEL and PIPRECIA multi-criteria methods to weigh the evaluation criteria and calculate the security score for each smart contract. The security scores assigned to each smart contract provide valuable insights for traders and investors in the cryptocurrency market, highlighting the contract's robustness and reliability in the context of smart contract risks.
