Run the following command.

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 for free.

Then, you can create a .env file with the following.

ALCHEMY_POLYGON_RPC_URL='<your-own-alchemy-polygon-mainnet-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.

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.

yarn install

3. Compile Smart Contracts

Run the following command.

yarn compile

4. Test on Polygon Mainnet Fork 🔥

Run the following command.

yarn test test/flashloan.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:

yarn deploy --network polygon

It costs about 0.2 MATIC to deploy Flashloan contract.
