SolPg

Solana Playground (SolPg) Overview¶

Solana Playground (SolPg for short) is a browser-based integrated development environment (IDE) designed specifically for Solana smart contract (program) development. It allows developers to write, build, deploy, and test Solana programs directly in the browser without installing any local tools. SolPg significantly lowers the barrier to Solana development and is an ideal tool for learning and rapid prototyping.

Usage Flow¶

1. Create a New Project¶

Start from a template:

1. Visit https://beta.solpg.io/
2. Click "Create New Project"
3. Select a template (Anchor, Native Rust, etc.)
4. The project is automatically created and the editor opens

2. Write Code¶

Write a program using the Anchor framework:

use anchor_lang::prelude::*;

declare_id!("Program ID will be auto-generated");

#[program]
pub mod my_program {
    use super::*;

    pub fn initialize(ctx: Context<Initialize>) -> Result<()> {
        msg!("Hello from Solana Playground!");
        Ok(())
    }
}

#[derive(Accounts)]
pub struct Initialize {}

3. Compile the Program¶

Click the "Build" button:

• Compiles Rust code to BPF bytecode
• Generates the IDL file
• Displays compilation results and errors

4. Deploy the Program¶

Deploy to the blockchain:

1. Select the target network (Devnet recommended)
2. Ensure the wallet has sufficient SOL (Devnet can auto-airdrop)
3. Click "Deploy"
4. Confirm the transaction
5. Obtain the Program ID

5. Test Interaction¶

Write test scripts:

// Test file
describe("my_program", () => {
  it("Initialize", async () => {
    const tx = await pg.program.methods.initialize().rpc();
    console.log("Transaction signature:", tx);
  });
});

Run tests: - Click the "Test" tab - Click "Run" to execute tests - View test results and output
