 A TypeScript client for interacting with CosmWasm smart contracts in Nym validators. 

+Running examples
+-----------------
+
+With the code checked out, `cd examples`. This folder contains runnable example code that will set up a blockchain and allow you to interact with it through the client. 
+
 Running tests
 -------------

-The tests will be separated into three categories: unit, integration and mock.
-
-Currently the command to run all tests: 
-
 ```
 npm test
 ```

-The tests require `.env.example` being renamed to `.env`. The variables and their values for these tests are currently pointing to the `nym-sandbox` environment.
+You can also trigger test execution with a test watcher. I don't have the centuries of life left to me that are needed to fight through the arcana of wiring up a working TypeScript mocha triggered execution setup, so for now my Cargo-based hack is:

-`Tests are still in development` - the test libary is `jest` and the test script will execute currently with: `--coverage --verbosity false`
+
+```
+cargo watch -s "cd clients/validator && npm test"
+```
+
+It's ugly but works fine if you have Cargo installed. TypeScript setup help happily accepted here.

-# 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`
