Through a prospective analysis based on data from the Housing Bank, this study sought to illustrate how blockchain technology, with its dimensions of block, hash, information, and time signature, affects guaranteeing the legitimacy of electronic sales contracts in Metaverse. In view of the swift digital changes taking place in the banking industry and virtual settings, this study sought to investigate the nature of the relationship between blockchain dimensions and the dependent variable, namely electronic sales contracts. A descriptive strategy was used to accomplish the study's goals. The Housing Bank of Jordan was the study's goal, and the research sample was chosen utilizing a thorough survey procedure. Every Housing Bank branch that made up the study population was included in the sample. Employees in these branches IT personnel, compliance and risk staff, legal affairs staff, and digital transformation staff were given electronic questionnaires (210). The Statistical Package for the Social Sciences (SPSS) was used to examine the 191 questionnaires that were found to be valid for statistical analysis. The findings demonstrated a statistically significant connection between electronic sales contracts in the Metaverse and blockchain technology. The results also demonstrated a significant impact of each blockchain dimension individually. It was found that the block, hash, information, and time signature each play an active role in enhancing the legality of electronic contracts within the virtual environment. The research recommended developing clear regulatory and legislative frameworks to govern the use of smart contracts. Metaverse utilizes blockchain technology, ensuring legal recognition and enhancing the protection of contracting parties' rights.
