This project is an implementation of a simple React app that interacts with the Ethereum testnet chain Rinkeby. The user enters text into a form, clicks the send transaction button, uses Metamask to submit the transaction and then sends the text to the Ethereum blockchain and IPFS. Once that is complete, the app will output some text underneath the form informing the user the text was successfully submitted to the blockchain and IPFS. Running the app locally is much faster than the production version so please keep that in mind.

clone this repo $ cd Consensys-Academy-Final-Project/ $ npm install
-
Open another terminal and run the Ganache blockchain (remember to set up your seed phase in Metamask).
$ ganache-cli
-
Compile and migrate the smart contracts.
$ truffle compile $ truffle migrate
-
Run the tests to make sure the contract is working correctly.
