Template Ethereum Smart Contract Interaction

Template to interact with deployed smart contract on Ethereum's blockchain (Deprecated)

This template allows a user to (a) utilise a smart contract template that can be deployed on Ethereum's blockchain, (b) connect the smart contract to a local repository, (c) interact with the smart contract through a frontend, and (d) customize frontend whilst still being connected to the smart contract.

• (a): Secret.sol: Smart contract written in Solidity with two simple functions
• (b): app.js: Interacting with the smart contract on Ethereum's blockchain - change two variables to add your own contract once you have deployed it.
• (c): app.js and index.html: Intuitive and simple interaction between the html (frontend) and JavaScript (using web3.js to interact with the smart contract)
• (d): index.css: Simple CSS to customize the website

Get Started

1. Clone Repository
2. cd To Repository
3. Run npm install
4. Run local server: npm run dev
5. Edit changes to the template in a code editor. Changes are automatically shown on localhost.

The smart contract

This repository is connected to a deployed contract on Ropsten Test Network. The smart contract in this repository [Secret.sol] is simply included as a smart contract template. To add your own contract:

1. Use the smart contract in this repository as your template
2. Go to Remix IDE (https://remix.ethereum.org/) and try interacting with the template to check that everything works
3. Deploy the contract
4. Go to [app.js] and change the ABI and var contractAddress

Secret.sol

Our template contract is written in Solidity and has two main funcitons:

• setSecretWord allows the user to set "a secret word"
• getSecretWord: retrieving the latest "secret word"

The file is included in this repo for reference, but not used for other purposes. The exact same smart contract is deployed on Ropsten - hence, changes in this file will not affect the template.

Please read:

1. You need MetaMask for this template - it is injecting the web3
2. If you are using the pre-made template, remember switching to "Ropsten Test Network" on MetaMask
3. Don't have Ether on your Ropsten Account? Use Faucet (https://faucet.metamask.io/)
