Hello World

Project goal

Ship a minimal hello-world style Solana project and execute it successfully.

Milestones

1. Initialize the project structure.
2. Implement the smallest useful instruction.
3. Execute the instruction and inspect the result.
4. Verify expected state changes.

Reuse from quick start: read account state

Before moving to larger projects, reuse the exact account-read workflow from /docs/intro/quick-start/reading-from-network.

Use that walkthrough’s result to validate these fundamentals:

• executable is false for wallet accounts.
• owner is the System Program for wallet accounts.
• lamports reflects the funded balance.
• space is 0 for system wallets with no custom data.

Verification

• The program runs without runtime errors.
• Transaction confirmation is successful.
• Expected output/state is visible in logs or account data.
