Automatic Code and Test Generation of Smart Contracts from Coordination Models (Artifact)

Abstract

The companion paper proposes a formal approach for specifying and implementing decentralised coordination in distributed systems, with a focus on smart contracts. The model captures dynamic roles, data-driven transitions, and external coordination interfaces, enabling high-level reasoning about decentralised workflows. A toolchain supports formal model validation, Solidity code generation (extensible to other smart contract languages), and automated test synthesis. Although targeting blockchain platforms, the methodology is platform-agnostic and may generalise to other service-oriented and distributed architectures. The expressiveness and practicality of the approach are demonstrated through modelling and realising coordination patterns in smart contracts.
This artifact accompanies our paper [Elvis Konjoh Selabi et al., 2026]. It provides a toolchain for generating smart contract code from EDAM (Extended Data-Aware Machines) specifications. The artifact includes the complete source code, a Docker image for easy deployment, pre-generated experiment data (generated code, automated tests, and mutation testing results), and reproduction scripts.
