  4. create React App (in app folder)
  5. phantom wallet intigration in react

Create new wallet

cd my-solana-wallet solana-keygen grind --starts-with cf:1 solana config set --url devnet solana airdrop 2 -k [wallet.json]

Deploy program

run yarn install in root directory set newly generated wallet address in "Anchor.toml" file run cargo clean , anchor build and solana address -k target/deploy/solana_crowdfunding_dapp-keypair.json copy new program id and past it in "Anchor.toml" and "lib.rs" files run anchor build && anchor deploy

Explain Rust Program

In this program we use 4 struct

  1. Initialize: This struct use for create and initialize the PDA. Whenver we create a new compaign that program will first create the PDA for thet compaign and that PDA will hold the program data and balance that any one will donate.
  2. Withdraw This struct use for the withdraw balance from PDA and only admin who will create the compaign can withdraw the SOL.
  3. Donate This struct use when a doner wants to donate an ammount of SOL and tha PDA will hold that SOL.
  4. Compaign This is the basics struct that use in above all structs.

Functions that we use in this program

  1. initialize(ctx: Context, name: String, description: String) -> Result<()> Use for create and initialize new compaign. This function gat the 3 perameters 1: Initialize struct, 2: name String and description String.
  2. withdraw(ctx: Context, amount: u64) -> ProgramResult Use for withdraw the SOL from compaign PDA. This function get 2 parameters 1: Withdraw struct and amount u64.
  3. donate(ctx: Context, amount: u64) -> ProgramResult Use for donate SOL to a compaign. This function get 2 parameters 1: Donate struct and amount u64.

Use this application

  1. run this command in app folder npm run and open it on web browser
