# Poly-Flash
An open source flashloan smart contract on polygon network
## Installation
### 1. Install [Node.js](https://nodejs.org/en/) & [yarn](https://classic.yarnpkg.com/en/docs/install/#windows-stable), if you haven't already.
### 2. Clone This Repo
Run the following command.
```bash
git clone https://github.com/yuichiroaoki/poly-flash.git
cd poly-flash
```
## Quickstart
### 1. Setup Environment Variables
You'll need an `ALCHEMY_POLYGON_RPC_URL` environment variable. You can get one from [Alchemy website](https://alchemy.com/?r=33851811-6ecf-40c3-a36d-d0452dda8634) for free.
Then, you can create a .env file with the following.
```
ALCHEMY_POLYGON_RPC_URL=''
```
#### Add your Private Key
If you want to execute flashloan on the polygon mainnet, you need to add your `PRIVATE_KEY` environment variable, [with a private key from your wallet](https://metamask.zendesk.com/hc/en-us/articles/360015289632-How-to-Export-an-Account-Private-Key).
```
PRIVATE_KEY='your-PRIVATE_KEY'
```
\*Note: If using metamask, you'll have to add a `0x` to the start of your private key)
### 2. Install Dependencies
Run the following command.
```bash
yarn install
```
### 3. Compile Smart Contracts
Run the following command.
```bash
yarn compile
```
### 4. Test on Polygon Mainnet Fork 🔥
Run the following command.
```bash
yarn test test/polygon/dodoflash.test.ts
```
## Deploy
Once you have successfully done the above quickstart and added your private key to .env file, you can deploy your smart contract with the following command:
```bash
yarn deploy --network polygon
```
It costs about 0.2 MATIC to deploy `Flashloan` contract.
