 1 | #  Smart Contracts That Power the Redacted Cartel Protocol🦋:
 2 | 
 3 | Here are the contracts that power REDACTED V1. Our V1 is a friendly fork of OHM, however, it contains a handful of key differences:
 4 | - Reserve assets have variable values (that can be set by calling setFloor() within our treasury)
 5 | - Bond contracts have been designed to return fees to Olympus
 6 | - Different bonding calculators due to our main LP pair being between 2 9dp coins, as opposed to a 9dp/18dp pair
 7 | 
 8 | ## Tech
 9 | 
10 | Redacted Cartel  uses a number of open source projects to work properly:
11 | 
12 | - Hardhat - Ethereum development environment.
13 | - Typescript - Strongly Typed JS
14 | - Typechain - TS Types for Solidity Smart Contracts
15 | - Node - JS runtime
16 | 
17 | 
18 | And of course Redacted Cartel itself is open source with a public repository on GitHub.
19 | 
20 | ## Installation
21 | 
22 | Redacted Smart Contracts requires [Node.js](https://nodejs.org/) v10+ to run.
23 | 
24 | Install the dependencies and devDependencies and start the server.
25 | 
26 | ```sh
27 | cd Redacted-Smart-Contracts
28 | yarn install
29 | ```
