Your First Build

This is the simplest challenge in the entire course. Your goal: hit the Build button and see it succeed.

The starter code is a minimal Anchor program that compiles with zero changes. Don't modify anything — just click Build and watch the build server compile your first Solana program.

What to Expect

• The build takes 30-60 seconds on first run (dependencies are cached after that)
• You'll see compiler output in the panel below
• A green checkmark means your program compiled to a .so binary
• The build UUID is your compiled program's identifier

Why This Matters

This proves the pipeline works end-to-end: your code leaves the browser, reaches the build server, gets compiled by cargo-build-sbf, and the result comes back. Every lesson after this builds on this foundation.
