Ethereum is the first blockchain-based decentralized computing platform that has standardized this type of tokens into a well-defined interface, namely ERC721. We propose a framework that provides developers with a smart contract suite that offers complete implementations of the ERC721 standard and common extensions and features frequently encountered in ERC721-based applications. We introduce a specification language that enables customization and configuration of the smart contract suite by including and excluding the supported features and extensions. We evaluate the smart contract suite for its extensibility and reusability and compare the metrics with four reference implementations tackling a similar problem. In addition to this, we evaluate and analyze the effort and efficiency of the specification language in comparison to manual configuration of the smart contract suite. Our contribution lies in examining quality metrics for code extensibility and reusability and determining the more insightful metrics for assessing these quality attributes in the context of Solidity smart contracts. Additionally, from the lines of code metric, We conclude that our specification language offers a simple and efficient alternative to manual smart contract suite customization.},
