• This DApp relies on the Sui blockchain framework for its smart contract functionality.
• Ensure you have the Move compiler installed and configured to the appropriate framework (e.g., framework/devnet for Devnet or framework/testnet for Testnet).

Sui = { git = "https://github.com/MystenLabs/sui.git", subdir = "crates/sui-framework/packages/sui-framework", rev = "framework/devnet" }

Follow these steps to deploy and use the Charity Donation Platform:

1. Move Compiler Installation: Ensure you have the Move compiler installed. Refer to the Sui documentation for installation instructions.

2. Compile the Smart Contract: Switch the dependencies in the Sui configuration to match your chosen framework (framework/devnet or framework/testnet), then build the contract.

   sui move build

3. Deployment: Deploy the compiled smart contract to your chosen blockchain platform using the Sui command-line interface.

   sui client publish --gas-budget 100000000 --json
