# Flash Arbitrage

## Overview

To reduce the cost and risk of arbitrage, I use FlashLoan for cross-protocol arbitrage so that I only need to pay the fees of FlashLoan to complete a series of transactions. It calls the `flashloansimple()` method from Aave's pool,  trades between the two platforms, and finally repays the fund to the pool. The entire operation is done within one transaction.

## Usage
When all contracts have been deployed, you can stake some assets to the contract, and call the `execute()` method to initiate transactions.

```solidity
flashArbitrage.deploy(USDC, 5e6);  # remember to approve assets
flashArbitrage.execute(
    'uniswap',     # buy WMATIC on Uniswap (using USDC)
    'sushiswap',   # sell WMATIC on Sushiswap (receive USDC)
    USDC,          # borrow USDC ( from AAVE )
    WMATIC,        # trade WMATIC
    100e6           # borrow amount, all-in one trade.
);
```
## Development

```Shell

# Apply an ETHERSCAN_KEY: https://polygonscan.com/apis
# PRIVATE_KEY: Export from your Wallet
cp .env.example .env
make test

# if tests all passed, deploy all contracts.
# scripting is a way to declaratively deploy contracts using Solidity
# instead of using the more limiting and less user friendly `forge create`.
make scripting

# if scripting isn't ok, you can deploy a single contract at once time.
make deploy-contract DEPLOY_CONTRACT={DEPLOY_CONTRACT} CONSTRUCTOR_ARGS={CONSTRUCTOR_ARGS}
```
