This project consists of a smart contract and a script to interact with it and perform flash loans on Ethereum. A flash loan is a cryptocurrency loan that must be repaid in the same transaction. It is a powerful feature that allows developers to temporarily leverage large amounts of liquidity to carry out complex financial operations.

The smart contract in this project is called contractExample.sol. It is an implementation of the IERC3156FlashBorrower interface that allows receiving a flash loan and executing custom business logic. In this example, an unlimited approval is set for the received loan, and additional logic can be added to carry out specific trading operations.

The testnet.js script is a Node.js script that uses the ethers.js library to interact with the flash loans smart contract.

Before running the testnet.js script, make sure to configure the following environment variables in a .env file:

PRIVATE_KEY=YourPrivateKey
PROVIDER=EthereumProviderURL

Replace YourPrivateKey with the private key of the account that will perform the flash loan, and EthereumProviderURL with the URL of the Ethereum provider you want to connect to. Do not share your private key with anyone

1. Clone this repository on your local machine.
2. Run npm install to install the necessary dependencies.
3. Configure the environment variables in a .env file.
4. Modify the value of flashLoanReceiverAddress in the testnet.js script with the address of your custom smart contract that implements the IERC3156FlashBorrower interface.
5. Modify the values of flashLoanProviderAddress, tokenAddress, and vaultOfToken according to your needs.
6. Run node testnet.js to perform a flash loan.

I am not responsible for any misuse of this information, and I do not recommend implementing this on the mainnet, make sure you perform the necessary tests on the testnet and make sure you understand how a flash loan works before you implement it.

All this project is made thanks to the documentation of Equalizer Finance, which you can find at: https://docs.equalizer.finance/

Enjoy exploring the possibilities of flash loans on Blockchain!😁😁
