@@ -3,26 +3,20 @@ Nym Validator Client

 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
 ```

-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:
+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.

-
-```
-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. 
+`Tests are still in development` - the test libary is `jest` and the test script will execute currently with: `--coverage --verbosity false`

+# 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`

Bogdan-Ștefan Neacşu	0b6adf59ce	Feature/fix gateway sign (#1004 ) * Include version check in sign command * Ask for wallet address the same way as mixnode The reason for this is that the cosmos mnemonic that is asked at init is for the address that gets rewarded for gateway usage.
