## Usage
The Contract module is a work in progress. The following examples show how this Contract module
can be used to instantiate and call contracts.
- [`ink`](https://github.com/paritytech/ink) is
an [`eDSL`](https://wiki.haskell.org/Embedded_domain_specific_language) that enables writing
WebAssembly based smart contracts in the Rust programming language. This is a work in progress.

This module executes WebAssembly smart contracts. These can potentially be written in any language
that compiles to web assembly. However, using a language that specifically targets this module
will make things a lot easier. One such language is [`ink`](https://github.com/paritytech/ink)
which is an [`eDSL`](https://wiki.haskell.org/Embedded_domain_specific_language) that enables
writing WebAssembly based smart contracts in the Rust programming language.
