Testing

The testing is optimized for a successful arbitrage with a Flash Loan.

Before running the test you should run in a console:

ganache-cli --fork EthereumNode-URL@13009534 --unlock 0xE8E8f41Ed29E46f34E206D7D2a7D6f735A3FF2CB

(The block number is important for the testing).

Then, to run the test:

truffle test

Deployment in Polygon

To deploy the contract to the Polygon-Mainnet, run:

$ truffle migrate --network polygon_mainnet

Before deploy it you must change the Aave: Leending Pool Address Provider V2 for its address at Polygon, which is: 0xd05e3E715d945B59290df0ae8eF85c1BdB684744. Also, make sure you have enough MATIC for deployment.
