Introducing Fondant – Your Seamless Casper Blockchain Testing Tool

Fondant, an intuitive, all-in-one, open-source development and testing toolkit that simplifies the process of creating and debugging Casper-based applications, is the latest grant recipient of the Casper Accelerate Grant Program.

Fondant offers an integrated testing environment for decentralized app development on Casper. With Fondant, developers can quickly fire up a personal Casper network, run tests, explore blocks, and inspect the chain operations. Everything is wrapped up in a clean and intuitive UI.

Casper has a unit test framework for smart contracts. DApps can implement their tests to verify business functionality, with projects using Docker in Github for unit testing. Fondant provides a nice application to manage and work with local Casper networks, spin them up ad-hoc, kill them, restart them, drill down into the blocks, and deploy with a visual tool. Fondant simplifies the testing process and provides a quick start for dApp development and testing.

Fondant offers key features aimed at simplifying the development and testing process for Casper blockchain applications.

Local Casper Network

Fondant allows developers to start up a local Casper network without having to use the command line. All you need is Docker and Fondant to have a local network to test your code against.  

Track Every Network Action

Fondant allows developers to monitor and analyze every action within their network, ensuring that it operates with optimal speed and dynamics. By tracking network actions, developers can identify bottlenecks and areas for improvement, leading to enhanced performance.


Inspect Deploy Structures

Developers can delve into Casper's deploy structures using Fondant, gaining a deep understanding of their architecture for optimal performance and functionality. By inspecting deploy structures, there can be identified potential issues and optimized their applications for efficiency. As an open-source project, developers are encouraged to contribute to its ongoing development, ensuring that the tool evolves to meet the changing needs of the ecosystem.

Explore Internal Chain Logs

Fondant provides developers access to internal chain logs, enabling them to gain valuable insights into the chain operations. By exploring these logs, developers can audit the chain's activities and identify potential areas for enhancement. This allows for continuous improvement and refinement of blockchain applications.

Summary for Developers

Fondant is committed to fostering long-term collaboration within the Casper community. Fondant is designed to work seamlessly with the existing Casper toolchain. This integration ensures that developers can use Fondant alongside other tools without the need for cumbersome adjustments or configurations. For Casper developers, Fondant represents a solution that streamlines the development and testing process.

Fondant's community-driven approach ensures that the tool remains responsive to the needs of its users. Fondant will not only enhance the efficiency of individual developers but also contribute to the overall growth and maturation of the Casper ecosystem.
