CCP + Bread Fundraising Contract

This project implements a fundraising smart contract using the Mina protocol and zero-knowledge proofs via o1js and the fts-scaffolded-xt library. It allows donors to contribute funds in the form of tokens towards a fundraising goal and includes two withdrawal methods:

• Donor Refunds: Allows donors to reclaim their donation if the deadline passes without reaching the goal.
• Beneficiary Claim: Allows the beneficiary to claim the total donation amount if the fundraising goal is met after the deadline.

Project Structure

• src/Fundraiser.ts
  Contains the smart contract logic for donations, refunds, and beneficiary withdrawals.
• src/fundraiser_runner.ts
  A runner script that deploys and initializes the token and fundraiser contracts, simulates donations, time progression, refunds, and finally the beneficiary withdrawing funds.

Installation

1. Clone the repository.

2. Install dependencies using:

   npm install

Building the Project

To compile the TypeScript sources into JavaScript, run:

npm run build

Running the Project

You can run the local simulation of the fundraiser with:

npm run run

Alternatively, for debugging with TypeScript, use:

npm run debug

This will execute the fundraiser_runner.ts script which:

• Deploys and initializes the token and fundraiser contracts.
• Executes a series of transactions simulating donations, refunds, and ultimately a beneficiary claim.

Code Quality and Formatting

• ESLint is configured to lint TypeScript and JavaScript files.
• Prettier is set up to enforce code formatting.
• Husky hooks are configured to run linting and formatting before commits.

Additional Notes

• This project uses dummy proofs and verification keys for testing and demonstration purposes.
