Here's how you can inspect a Solana contract:

1. IDL (Interface Definition Language):

   • If the program was built using Anchor (a popular Solana framework), developers often publish the .json IDL file.

   • You can find IDLs on sites like https://app.project-serum.com, or if you know the program ID, you can fetch it using the Anchor CLI:

     php-template
     

     anchor idl fetch <PROGRAM_ID>

2. Source code (Rust):

   • Check public GitHub repositories if the project is open source. Many Solana programs publish their code under their project name (e.g., Mango, Jupiter).

   • Search on GitHub using:

     php-template
     

     <PROGRAM_ID> site:github.com

3. Solana Explorer Limitations:

   • Solana Explorer or Solscan mainly show deployed program metadata, not function-level details unless the devs explicitly publish them.

Bonus Tip:

If you're building or auditing programs and want full control over IDLs, deployment, and debugging, you might want to use custom tooling. Our team at Telbox builds and deploys Solana programs at scale with built-in IDL exposure and testing support — feel free to check it out if you're exploring deeper Solana development workflows.
