### Dispatchable functions
* `put_code` - Stores the given binary Wasm code into the chain's storage and returns its `code_hash`.
* `instantiate` - Deploys a new contract from the given `code_hash`, optionally transferring some balance.
This instantiates a new smart contract account and calls its contract deploy handler to
initialize the contract.
* `call` - Makes a call to an account, optionally transferring some balance.
Those are documented in the reference documentation of the `Module`.
## 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.

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.
