Build & Deploy Your First Program

This guide provides a step-by-step overview of deploying a program on BARA SVM. Familiarity with command-line tools is necessary.

1. Install CLI Tools

Ensure that the Solana command line tools are installed as you will be using these tools throughout the deployment process.

2. Write Your Program

Develop your program logic. For those using Rust with Anchor, input your program logic into the lib.rs file located in the src directory of your project. Confirm that your program compiles correctly and passes all tests.

3. Build Your Program

Compile your program to a BPF (Berkeley Packet Filter) executable, the format required for on-chain programs:

With Anchor

Run anchor build. Anchor manages the compilation details.

Without Anchor

Use cargo build-bpf for direct Rust usage.

4. Deploy Your Program

Before deploying your program, ensure your CLI is set to the BARA Devnet network using the following command:

solana config set --url https://devnet.bara.games

After deploying your building your program and configuring your RPC URL, you can deploy your program with the following command:

solana program deploy <PATH_TO_YOUR_COMPILED_PROGRAM>

Ensure that you have enough SOL in your wallet to cover deployment costs. You can get some devnet tokens from the BARA faucet.

---

After configuring your network, you may now deploy your program to BARA. Use the following commands based on your setup:

With Anchor

If the Anchor CLI is installed, you can deploy your program with the following command. This handles the deployment automatically.

anchor deploy

Without Anchor

If you're using the native solana method to author your program, you can also use the Solana CLI to deploy your program.

5. Verify Deployment

Post-deployment, check that your program operates as intended. Interact with your program using Solana's web3.js library or the CLI tools to send transactions.

Additional Tips:

• Keep your program's keypair secure for future upgrades or interactions.

• Monitor the network and your program's performance, particularly if it gains widespread usage.

Example: "Hello BARA!" Program

This example implements a simple Greeting Counter Program on BARA.

With Solana Native Program

use borsh::{BorshDeserialize, BorshSerialize};
use solana_program::{
    account_info::{next_account_info, AccountInfo},
    entrypoint,
    entrypoint::ProgramResult,
    msg,
    program_error::ProgramError,
    pubkey::Pubkey,
};

#[derive(BorshSerialize, BorshDeserialize, Debug)]
pub struct GreetingAccount {
    pub counter: u32,
}

entrypoint!(process_instruction);

pub fn process_instruction(
    program_id: &Pubkey,
    accounts: &[AccountInfo],
    _instruction_data: &[u8],
) -> ProgramResult {
    
    msg!("Hello, Sonic World!");
    
    let accounts_iter = &mut accounts.iter();
    let account = next_account_info(accounts_iter)?;

    if account.owner != program_id {
        msg!("Greeted account does not have the correct program id");
        return Err(ProgramError::IncorrectProgramId);
    }

    let mut greeting_account = GreetingAccount::try_from_slice(&account.data.borrow())?;
    greeting_account.counter += 1;
    greeting_account.serialize(&mut *account.data.borrow_mut())?;
    
    msg!("Greeted {} time(s)!", greeting_account.counter);
    Ok(())
}

With Anchor Program

If you are building with Anchor, you may use the variant below. Please remember to change the program ID after building your program with anchor build before deploying it.

use anchor_lang::prelude::*;

// !!! Replace with your program ID after running `anchor build` !!!
declare_id!("<REPLACE_WITH_YOUR_PROGRAM_ID>");

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

    pub fn initialize(ctx: Context<Initialize>, authority: Pubkey) -> Result<()> {
        let greeting_account = &mut ctx.accounts.greeting_account;
        greeting_account.counter = 0;
        greeting_account.authority = authority;
        Ok(())
    }

    pub fn increment_greeting(ctx: Context<IncrementGreeting>) -> Result<()> {
        msg!("Hello, Sonic World!");

        let greeting_account = &mut ctx.accounts.greeting_account;
        greeting_account.counter += 1;

        msg!("Greeted {} time(s)!", greeting_account.counter);
        Ok(())
    }
}

#[derive(Accounts)]
pub struct Initialize<'info> {
    #[account(init, payer = user, space = 8 + 4 + 32)]
    pub greeting_account: Account<'info, GreetingAccount>,
    #[account(mut)]
    pub user: Signer<'info>,
    pub system_program: Program<'info, System>,
}

#[derive(Accounts)]
pub struct IncrementGreeting<'info> {
    #[account(mut, has_one = authority)]
    pub greeting_account: Account<'info, GreetingAccount>,
    pub authority: Signer<'info>,
}

#[account]
pub struct GreetingAccount {
    pub counter: u32,
    pub authority: Pubkey,
}

Run your dAPP on BARA Devnet

Example "Hello World" application in TypeScript:

Running the above script [either with Solana Native, or with Anchor] programs should output the following:

Use 'solana confirm -v TsCwj8s8meQFSfqUKdHqDQVzfUbqRcugP2gJ5kaGCj4v4D7aKvohqQQncvUFunqZVH9sS6jhESMjwe6SHGPfrXf' to see the logs
Sonic Greeting successful. Account data: GreetingAccount { counter: 1 }
Done
