Promise on ETH 🤝 🔷

Promise on ETH is a decentralized application built with Scaffold-ETH 2 for its Hackathon. This DApp allows users to set up goals and motivate themselves to complete them by setting up a failing fee in ETH. Users have to assign a supervisor who will confirm if the goal is completed or failed by the deadline. If the creator of the goal fails, loses the ETH.

Demo Video

Features

• Users can create goals with deadlines and failing fees in ETH (promise on ETH).
• Supervisors can confirm if a goal is completed or failed.
• If the goal is failed, the user loses their failing fee.
• If the goal is completed, the user gets back their ETH.
• Users can browse other users' goals for inspiration.
• Users can check the goals they currently have.
• Supervisors can view the goals they got assigned to supervise and mark them as complete or failed.
• A security withdrawal feature allows the contract owner to withdraw the failing fee if the supervisor's account is lost (2 years after deadline, could maybe lower it to a few months).

Potential Future Developments

Some potential future developments for Promises on ETH could include:

• Implement an optional staking feature, allowing users to earn rewards for completing their goals.
• Allow users to create group goals with multiple participants, increasing collaboration and motivation.
• Introduce an NFT-based achievement system to gamify the goal-setting process and encourage user engagement.
• Adding a reward system for supervisors.
• Implementing a voting mechanism for supervisors.
• Enhancing the user interface for better user experience.
• Adding notifications and reminders for upcoming deadlines.

Quickstart

To get started with Scaffold-Eth 2, follow the steps below:

1. Clone this repo & install dependencies

git clone https://github.com/tokodev/eth-promises.git
cd eth-promises
yarn install

2. Run a local network in the first terminal:

yarn chain

This command starts a local Ethereum network using Hardhat. The network runs on your local machine and can be used for testing and development. You can customize the network configuration in hardhat.config.ts.

3. On a second terminal, deploy the test contract:

yarn deploy

This command deploys a test smart contract to the local network. The contract is located in packages/hardhat/contracts and can be modified to suit your needs. The yarn deploy command uses the deploy script located in packages/hardhat/deploy to deploy the contract to the network. You can also customize the deploy script.

4. On a third terminal, start your NextJS app:

yarn start

Visit your app on: http://localhost:3000. You can interact with your smart contract using the contract component or the example ui in the frontend. You can tweak the app config in packages/nextjs/scaffold.config.ts.

Run smart contract test with yarn hardhat:test

• Edit your smart contract YourContract.sol in packages/hardhat/contracts
• Edit your frontend in packages/nextjs/pages
• Edit your deployment scripts in packages/hardhat/deploy
