Liquidity: A Smart Contract Language for Dune Network

Sep 8, 2023 | Blockchain

Welcome to the world of Liquidity! This brilliant language is designed specifically for programming smart contracts on the Dune Network (and Tezos). By harnessing the syntax of OCaml (and ReasonML), Liquidity not only adheres to the strict security principles of Michelson but also provides developers with powerful tools to create efficient and secure smart contracts.

The Liquidity Project

The Liquidity project encompasses several important components:

  • A compiler that converts Liquidity files (with the .liq extension) to Michelson.
  • A de-compiler that translates Michelson files (ending in .tz) back to Liquidity.
  • A Tezos client for deploying and interacting with Liquidity contracts.

Features of the Liquidity Language

Liquidity boasts several exciting features that enhance its usability:

  • Full coverage of Michelson: Anything that can be coded in Michelson can also be coded in Liquidity.
  • Local variables: Unlike the stack manipulations seen in Michelson, Liquidity allows developers to store values in local variables, making the code more intuitive.
  • High-level types: Liquidity enables the definition and use of sophisticated types like sum-types and record-types, increasing the expressiveness of the programming language.

Branches of Liquidity

In the Liquidity project, there are two significant branches:

  • Master Branch: This is the go-to for the latest stable release, ensuring reliability for users and developers.
  • Next Branch: This branch houses the upcoming version of Liquidity, which is intended for experimentation. Features may still undergo modifications before their next release, making it an exciting place for innovators!

Installation and Usage

Ready to dive in? You’ll need to follow specific steps to install and use Liquidity. For detailed installation instructions, visit the installation instructions and check out the usage documentation for help on getting started.

Documentation

To ensure users can navigate through Liquidity with ease, comprehensive documentation is available:

Status of Liquidity

All features of Michelson are fully supported in Liquidity, allowing for seamless transitions between both languages. All test contracts from the Dune Network repository can be decompiled to Liquidity and then recompiled to Michelson without any issues.

Troubleshooting Ideas

While working with Liquidity, you may encounter some challenges. Here are some troubleshooting ideas:

  • If you experience issues with code compilation, double-check that your Liquidity file (.liq) adheres to the required syntax.
  • For decompilation problems, ensure that the Michelson file (.tz) is correctly formatted and follows Michelson language rules.
  • Always refer to the latest documentation for updates on installation or any new features added to Liquidity.
  • If you discover any bugs or unexpected behaviors, consider reaching out to the community or checking the relevant issue tracker for known issues.
