dApp Development Framework

Ontology's dApp development framework - Punica suite

Punica suite is the first dApp development framework based on the Ontology platform that encapsulates and provides all the necessary development tools and resources in a package so as to allow developers to swiftly get acquainted with dApp development.

The primary functions and attributes of the framework as as follows:

  • Supports unit and functional testing, relatively simpler than the SDK testing mechanism, thus faster and convenient.

  • Smart contract compilation, deployment, and testing can all be carried out using the respective commands in the command line interface, thereby making the process more efficient.

The debug functionality is already a part of the SmartX IDE. In the future, the CLI will also provide the same.

  • Solo-chain allows developers to track and check the on-chain data, which is a lot more convenient and efficient than using the testnet or setting up a private node.

  • The SDKs and dAPI available in different programming languages can be used to develop applications and software for all different kinds of user groups.


A whole set of development tools are a part of the Punica suite. The tools include:

  • Punica Python CLI and Punica Typescript CLI command line tools allow the developer to conveniently compile, deploy, and test smart contracts on the TestNet, MainNet and the privatenet.

  • Punica box provides a variety of dApp templates and application use cases.

  • Solo-chain is the private chain management tool that allows the developers to deploy a private node thereby making testing a lot more convenient.

  • VS code extension is a Visual Studio plugin.

Developers looking for a starting point to get acquainted with the Ontology development framework are suggested to start learning from Punica CLI.

After installing Punica, developers can start using SmartX to develop smart contracts while referring to Punica boxes.
