Joint Savings Contract

The goal of this project was to create a contract that can send ETH to either one of two savings accounts. This contract will have a withdraw function that requires that the recipient of the funds in the smart contract are your two savings accounts. Otherwise, funds will not be withdrawn. There is a deposit function and a fallback function that can be used to send funds into the contract. There is a function setAccounts that will take in two payable addresses account1 and account2 that will receive savings from our smart contract.

Testing Contract Functionality

Using deposit function to deposit funds

I was able to send 1 Ether, 10 Ether and 5 Ether to the contract address using the deposit function. The contractBalance would show the balance of the contract in wei.

Withdrawing funds to accountOne

Using the withdraw function I was able to withdraw 5 Ether to accountOne. You can confirm using lastToWithdraw, lastWithdrawAmount and contractBalance to check if the withdraw was successfull.

Withdrawing funds to accountTwo

I was able to withdraw 10 Ether to accountTwo. I can confirm using lastToWithdraw, lastWithdrawAmount and contractBalance to check if the withdraw was successfull.

Improvements

I would add a modifier onlyOwner to the contract that would require msg.sender to equal owner of the deployed contract. Then add the modifier to setAccounts funtion son only the owner can set the accounts.
