The Charity Donation Tracking module facilitates the transparent and accountable management of charitable donations, enabling donors, recipients, and authorities to interact in a decentralized manner. It offers functionalities for making donations, tracking their purposes and amounts, validating donations by authorities, transferring donations to recipients, and managing donation cancellations.

• id: Unique identifier for the donation.
• donor_address: Address of the donor making the donation.
• purpose_id: Identifier for the purpose of the donation.
• amount: Amount of the donation.
• donation_fund: Balance of SUI tokens representing the donated amount.
• recipient_is_pending: Boolean indicating whether the donation is pending receipt by the recipient.
• authority_validation: Boolean indicating whether the donation has been validated by the authority.

• id: Unique identifier for administrative privileges within the charity tracking system.

• id: Unique identifier for authority privileges, allowing designated authorities to validate donations.

Allows users to make a donation by creating a new donation object with the provided purpose and amount.

Creates a capability for authority to validate donations.

Allows editing the purpose ID of a donation, restricted to pending donations.

Allocates donation funds to a specific purpose, ensuring there are enough funds available.

Allows the authority to validate a donation.

Allows the recipient to receive a donation, transferring the donation fund and ownership.

Allows the authority to claim a donation after validation.

Allows the donor to cancel a donation, refunding the donation amount if not yet received by the recipient.

Allows the authority to validate a donation, marking it as validated.

Allows the authority to reject a donation, returning the donation amount to the donor.

1. Rust and Cargo: Install Rust and Cargo on your development machine by following the official Rust installation instructions.

2. SUI Blockchain: Set up a local instance of the SUI blockchain for development and testing purposes. Refer to the SUI documentation for installation instructions.

1. Clone the Charity Donation Tracking repository and navigate to the project directory on your local machine.

2. Compile the smart contract code using the Rust compiler:

   cargo build --release

3. Deploy the compiled smart contract to your local SUI blockchain node using the SUI CLI or other deployment tools.

4. Note the contract address and other relevant identifiers for interacting with the deployed contract.

To make a donation, invoke the make_donation function with the specified purpose and amount.

Authorities can validate or reject donations using the validate_with_authority or reject_donation functions, respectively.

Recipients can receive donations using the receive_by_recipient function, transferring the donation fund and ownership.

Donors can cancel donations that have not yet been received by the recipient using the cancel_donation function.

Donation purposes can be edited using the edit_purpose_id function, restricted to pending donations.

1. Utilize the SUI CLI to interact with the deployed smart contract, providing function arguments and transaction contexts as required.

2. Monitor transaction outputs and blockchain events to track the status of donations and transactions.

1. Develop web interfaces or applications that interact with the smart contract using JavaScript libraries such as Web3.js or Ethers.js.

2. Implement user-friendly interfaces for making donations, tracking purposes and amounts, and managing donation transactions within the Charity Donation Tracking platform.

The Charity Donation Tracking Smart Contract offers a decentralized solution for managing charitable donations, fostering transparency, accountability, and efficiency in the donation process. By leveraging blockchain technology, donors, recipients, and authorities can engage in secure and transparent transactions, ultimately contributing to the greater good of society.
