Liquidity: a Smart Contract Language for Tezos
Liquidity is a language to program Smart Contracts for Tezos. It uses the syntax of OCaml, and strictly complies to Michelson security restrictions.
The Liquidity Project
The Liquidity project contains:
- A compiler from Liquidity files (.liq extension) to Michelson
- A de-compiler from Michelson files (.tz extension) to Liquidity
- An evaluator of Michelson contracts
The Liquidity Language
The Liquidity language provides the following features:
Full coverage of the Michelson language: Anything that can be written in Michelson can be written in Liquidity
Local variables instead of stack manipulations: values can be stored in local variables. The only restriction is that local variables do not survive to
Contract.call, following the philosophy of Michelson to force explicite storage of values to limit reentrancy bugs.
High-level types: types like sum-types and record-types can be defined and used in Liquidity programs.
master branch contains the latest stable release. The
branch contains the upcoming version: the language on the
branch is for experimentation, and features may be modified before the
Installation and Usage
All features of Michelson are supported in Liquidity. All tests from https://github.com/tezos/tezos/tree/alphanet/test/contracts can be decompiled to Liquidity and recompiled to Michelson.
The current roadmap is:
Development of an online editor for Liquidity
Development of a proof assistant for Liquidity contracts
