Learning Solana

Welcome to my Solana learning repository! This repo contains various projects and experiments as I learn about Solana development using Rust and TypeScript.

Environment Setup

Before you begin, ensure you have the following installed:

• Node.js (LTS version recommended)
• Yarn
• Rust (install via rustup)
• Solana CLI
• Anchor CLI

Install Solana web3.js

   npm install @solana/web3.js

Set Up Local Solana Test Validator

• Command to start solana env locally

   solana-test-validator

• Connect to the local validator:

   solana config set --url localhost

1. Start development workflow

• For Rust-based Solana programs: You can use the Anchor framework to create and deploy your smart contracts.

   anchor init my_solana_project
   cd my_solana_project

Project Structure

my_solana_project/
├── Anchor.toml
├── Cargo.toml
├── programs/
│   └── my_solana_project/
│       └── src/
│           └── lib.rs
├── migrations/
├── tests/
│   └── my_solana_project.ts
└── target/

• Anchor.toml: Configuration file for the Anchor framework.
• Cargo.toml: Configuration for Rust dependencies and project settings.
• programs/: Contains the Rust smart contract (program).
• lib.rs: The main Rust source file where you’ll write your Solana program.
• tests/: Contains the TypeScript tests for your program.

2. Write your On-chain program on lib.rs

3. Build project

• build the project with following command

   anchor build

• sync the 32Bit hash generated in the build process with the following command

   anchor keys sync

4. Deploy the program

before deploying ensure your Anchor.toml file config

[programs.localnet]
    my_solana_project = "onchain-program-address"

[registry]
    url = "https://api.apr.dev"

[provider]
    cluster = "devnet" // change it accordinglly
    wallet = "~/localwallet1.json" // change the provider wallet address accordinglly

Deploy with the following command

anchor deploy
