However, developing smart contracts is non-trivial and challenging due to the lack of tools and expertise in this field. A promising solution to overcome this issue is to use Model-Driven Engineering (MDE), however, using models still involves a learning curve and might not be suitable for non-technical users. To tackle this challenge, chatbot or conversational interfaces can be used to assess the non-technical users to specify a smart contract in gradual and interactive manner. In this paper, we propose iContractBot, a chatbot for modeling and developing smart contracts. Moreover, we investigate how to integrate iContractBot with iContractML, a domainspecific modeling language for developing smart contracts, and instantiate intention models from the chatbot. The iContractBot framework provides a domain-specific language (DSL) based on the user intention and performs model-to-text transformation to generate the smart contract code. A smart contract use case is presented to demonstrate how iContractBot can be utilized for creating models and generating the deployment artifacts for smart contracts based on a simple conversation35-38eninfo:eu-repo/semantics/openAccessChatbotsBlockchainDomain specific languages (Computer science)Ethereum (Databases)Hyperledger composerModel-driven engineeringSmart contractsHugbúnaðargerðHugbúnaðarverkfræðiLíkönSamskiptaforritSamskiptatækniSamningarNetöryggiinfo:eu-repo/semantics/conferenceObject2021 IEEE/ACM Third International Workshop on Bots in Software Engineering (BotSE)10.1109/BotSE52550.2021.00015
