Procedure and Analysis

• Created two ERC-20 tokens tokenA and tokenB each having 1000 initial mint.

• Created a contract called SimpleDEX which handles the functionality of exchanging these tokens (A to B for a provided exchange Rate).

• The below picture showing all the deployed contracts which include the 2 ERC-20 tokens along with the SimpleDEX contract

• Below picture showing me fund the contract for 5 out of the 1000 minted tokens of B to ensure we can exchange via the SimpleDEX contract, some tokens of A to tokens of B provided a given exchange rate

• Below picture approving the SimpleDEX contract to spend given number of tokensA (for exchange of A to B)

• Below logs confirming successful transaction of tokens A to tokens B for given fixed exchange rate which here is given 1 for easy debugging
