A minimal Solana program built with Anchor, logging Hello, Solana! on-chain.
Fast, local, verifiable — perfect for first-contact with Anchor.

• Rust (smart contracts)
• Anchor Framework (program + Mocha tests)
• Solana CLI
• Node.js + Yarn/NPM
• Local validator / Devnet setup

anchor build

anchor test

You’ll see output like:

Program log: Hello, Solana!

That’s your program running successfully inside Anchor’s local test validator.

🌍 Optional: Deploy to Devnet

solana config set --url https://api.devnet.solana.com
solana airdrop 2
anchor build
anchor deploy

Copy your Program Id from the deploy output and ensure it matches: Anchor.toml → [programs.devnet] programs/solana-hello/src/lib.rs → inside declare_id!()

• programs/ – Rust smart contracts
• tests/ – JS/TS test scripts
• Anchor.toml – project configuration
• target/idl - Generated IDL after build

Hello, Solana! logged via Anchor.

🧪 Example Test import * as anchor from "@coral-xyz/anchor"; import { Program } from "@coral-xyz/anchor"; import { SolanaHello } from "../target/types/solana_hello";

describe("solana-hello", () => { const provider = anchor.AnchorProvider.env(); anchor.setProvider(provider); const program = anchor.workspace.SolanaHello as Program;

it("Says Hello, Solana!", async () => { const tx = await program.methods.initialize().rpc(); console.log("Transaction Signature:", tx); }); });

• Instruction: hello() — logs "👋 Hello, Solana!"
• Accounts: none (CPI-free), stateless demo
• ID (devnet): GWTzAruVThiratXikUeYHo8F1ruZJQiVvfWczQRiwNX9
• Explorer: https://explorer.solana.com/address/GWTzAruVThiratXikUeYHo8F1ruZJQiVvfWczQRiwNX9?cluster=devnet
