SmartML: Towards a Modeling Language for Smart Contracts

Smart contracts codify real-world transactions and automatically execute the terms of the contract when predefined conditions are met. This paper proposes SmartML, a modeling language for smart contracts that is platform independent and easy to comprehend. We detail the formal semantics and the type system, focusing on its role in addressing security vulnerabilities and attacks. Through case studies we show how SmartML contributes to the prevention of reentrancy attacks, illustrating its efficacy in reinforcing the reliability and security of smart contracts within decentralized systems.
