# Currency The Currency Module provides a fast and customizable way to launch a metagraph with native support for currency (L0 token) transactions. Unlike closed-loop systems such as smart-contract platforms, this framework offers enhanced flexibility by allowing direct modifications of application-level code. It encapsulates functionalities necessary for peer-to-peer token transactions, chain data construction, and more, in an easy-to-use package. Note that launching a token is not required when developing with the Metagraph Framework, and at present, the Metagraph Framework is also the most efficient way to launch a data-focused application with or without a token associated with it. Extending the framework with the Data module allows developers to build metagraphs with custom data ingestion, validation, and storage logic. See the [Data Application](https://docs.constellationnetwork.io/sdk/metagraph-framework/data/overview) section for more detail. By basing their metagraphs on this framework, developers gain the advantage of working with a proven set of underlying features and functionality in order to be able to focus on their project's own business logic rather than boilerplate functionality. Example projects are provided in order to speed up development. See [metagraph examples](https://github.com/Constellation-Labs/metagraph-examples) or use the `install-template` method of `hydra`. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
