【Abstract】In recent years, Blockchain technology has proved its efficiency in many domains. A smart contract is a software component allowing exposing services via the Blockchain network. Smart contracts are small programs that automatically execute the terms of an agreement when predetermined terms and conditions are reached. With the increasing growth in the popularity of smart contracts, searching, retrieving and understanding smart contracts before executing them becomes a significant challenge. Nevertheless, the majority of these contracts are closed source contracts. Therefore, users cannot understand their functionality and their internal mechanism. In addition, their description lacks the expressiveness and it didn't cover the QOS parameters. In this paper, we propose a Uniform Description language for Smart Contract named UDL-SC. This proposal is an extension of USDL based on the MDA approach to promote trust and minimize the ambiguity between the user and the contract provider.
