Introduction

This page guides you through creating, deploying, and verifying a simple Hello World Anchor program in Solana—all using CODI’s web-native interface. You’ll see how scaffold-agent generates boilerplate, deploy-agent publishes your contract, and the UI helps you inspect transactions on Devnet.

1. Scaffold Hello World

• scaffold-agent creates programs/hello-world with lib.rs, Anchor.toml, and TypeScript test boilerplate.

2. Inspect Generated Code

• lib.rs: Contains hello() instruction emitting a log via msg! macro.

• Anchor.toml: Configured for hello-world id and local cluster settings.

• tests/hello-world.ts: Stub test file expecting to import and call hello().

3. Build & Deploy

• deploy-agent compiles Rust code, generates IDL, and publishes the program to Devnet.

• On success, it prints the program ID and transaction signature.

4. Verify on Devnet

• Open the UI’s Explorer panel.

• Paste the transaction signature or program ID to view logs and account details.

• Confirm hello() executed by checking for Program log: Hello, Solana! entry.

5. Run Automated Test

• test-agent executes the generated TypeScript test suite, asserting that hello() emits the correct log.

• Review pass/fail output in the Tests pane.

6. Next Steps

• Customize Logic: Modify hello() in lib.rs to accept parameters.

• Advanced Tests: Add edge-case tests for input validation.

• Audit: Run audit to check for best practices even in simple programs.

Conclusion

The Hello Solana example demonstrates CODI’s seamless end-to-end flow: scaffolding, deploying, verifying, and testing—all without leaving your browser.
