'Build Your own Ethereum Transaction App with React and Solidity: (Part 1)' react solidity
transactionCountsis an array that will hold the addresses of the users that interact with our smart contract.
On this block of code, we are telling our smart contract to use a transfer event whenever a transfer is carried out between two accounts. This event will bear a record of the sender and receiver’s address, the amount sent, a remark made for the transaction, and a timestamp that will mark when the transaction was made.
constructor { owner=msg.sender; balanceOf[tx.origin]=msg.sender.balance; } function getOwner public view returns { return owner; } function sendMoney public returns { if balanceOf; event Transfer; struct TransferStruct { address sender; address receiver; uint256 amount; string remark; uint256 timestamp; } TransferStruct[] transactions; constructor { owner=msg.sender; balanceOf[tx.origin]=msg.sender.
Once you have clicked on the deploy orange button, a transaction success will be recorded on the terminal. You will see a deployed contract hash code on the bottom left of the page and a reduction in your ether balance.
