-This directory contains example code for javascript, python, and rust. Please note that **none of these examples are production-ready**, and are included really just to show how the client interacts with the Nym system.

-## Go
-There are two examples here: 
-* `binarysend`, which (as the name suggests) sends a binary file, and 
-* `textsend` which sends a raw text file. 
-
-Both examples send these files over the Nym mixnet to the address of your running Nym client, logging information in your terminal window. 
-
-## Javascript 
-The example included here starts a websocket server on port 8888, the ui of which can be used to send strings over the Nym mixnet to the address of your running Nym client. 
-
-### Prerequisites
-* Reasonably up to date `NodeJS` & `npm` (>= ~v12)
-
-### Running it
-Run the following commands:
-
-```
-# install dependencies
-npm install
-# start a webserver on port 8888 
-npm start 
-```
-
-Then open your browser to `localhost:8888`.

-# Basic Bandwidth Credential Generator 
-
-This directory contains the contract and unit tests for the `BandwidthGenerator` smart contract. 
-
-This contract allows users to generate Basic Bandwidth Credentials (BBCs) on the Nym cosmos blockchain using ERC20 representations of NYM as payment, utilising the Cosmos Gravity Bridge for cross-chain payment. 
-         
-BBCs are credentials that will be presented to Gateways by a Nym Client, and represent a certain amount of bandwidth which can be sent through the Nym Mixnet. 
-
-By default 1 NYM = 1 GB of bandwidth. The ratio of NYM - bandwidth is denominated in bytes, and represented in the smart contract by the `BytesPerToken` variable. This variable can be adjusted by the contract owner. 
-  
-The amount of bandwidth bought is calculated according to the following formula: 
-`(Token amount in 'wei' * BytesPerToken) / 10**18`
-
-## Usage 
-* `npm install`
-* `npx hardhat compile`
-* `npx hardhat test`

- * @dev   Contract for generating Basic Bandwidth Credentials (BBCs) on the Nym cosmos blockchain, 
- *        using ERC20 representations of NYM as payment. Utilises the Gravity Bridge for cross-chain payment. 
- *        
- *        Credentials represent a certain amount of bandwidth which can be sent through the Nym Mixnet. 
- *        By default 1 NYM = 1 GB of bandwidth. The `BytesPerToken` amount can be adjusted by the contract owner. 
- * 
- *        The amount of bandwidth bought is calculated according to the following formula: 
- *        `(Token amount in 'wei' / 10**18) * BytesPerToken`
