Flash Loans Exercise 1

Intro

In this exercise, your goal is to implement an ETH Pool that enables flash loans.

You will also implement 2 receivers contracts:

1. A "Receiver" contract which requests a flashloan and pays it back.
2. A "Greedy Receiver" contract which requests the loan and doesn't pay it back.

After implementing the contracts, you will have to test them and make sure that the logic works.

Tasks

Task 1

Implement the Pool.sol contract.

Complete the flashLoan function:

1. Revert the transaction in case there is not enough ETH in pool (Less than requested).
2. Call the getEth function on msg.sender with the requested amount of ETH.
3. Make sure that the ETH was paid back.

Task 2

Implement the Receiver.sol contract:

1. Complete the flashLoan function so it will request a flash loan from the pool.
2. Complete the getEth function so it sends back the ETH to the Pool contract.

Task 3

Implement the GreedyReceiver.sol contract:

1. Complete the flashLoan function so it will request a flash loan from the pool.
2. Complete the getEth function so it DOESN'T send back the ETH to the Pool contract.

Note: Should you consider anything else is needed to be implemented for the contracts to work, please proceed. The instructions given are not exhaustive.

Task 4

Complete the tests in the tests.js file.
