Solana program (smart contract) has a very unique programming model. A counter program is one of the simplest examples to demonstrate how data storage is handled. Meanwhile using Seahorse framework is the most elegant way to develop Solana programs.

Follow this blog to install Seahorse, your installations sequence will be Rust > Solana > Anchor > Seahorse.

The most stable software combination as of writing is as follows:

• Rust 1.77.2
• Solana 1.18.12
• Anchor 0.29.0
• Seahorse 0.2.0

1. Create a Solana wallet account with solana-keygen new if you haven't done so. Your private key is located at ~/.config/solana/id.json

2. Initialize your project folder with seahorse init <program_name>

3. Go to the project folder and build the Anchor sources with anchor build. It takes several minutes but only required to do once.

4. You may start writing your Seahorse program in programs_py/<program_name>.py

5. Run anchor keys list to find the correct program ID. Make sure the one found in Anchor.toml and that enclosed in the declare_id() statement are in sync.

6. Compile your Seahorse program into Anchor with seahorse build. You can also get the IDL under target/idl/

7. With the IDL, you can now start writing the Mocha test cases in tests/<program_name>.ts. Autocomplete is supported.

8. Run anchor test to deploy the Anchor program to localnet and run the test script at the same time.

9. Every time you modify the Seahorse program, changes are not synchronized to Anchor codes automatically. You may create a Node script in package.json to streamline the tasks.
