Solana Development

Build Solana programs using Anchor framework or native Rust. Both approaches share the same core concepts (accounts, PDAs, CPIs, tokens) but differ in syntax and abstraction level.

Quick Start

Recommended: Anchor Framework

Anchor provides macros and tooling that reduce boilerplate and increase developer productivity:

use anchor_lang::prelude::*;

declare_id!("YourProgramID");

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

    pub fn initialize(ctx: Context<Initialize>, data: u64) -> Result<()> {
        ctx.accounts.account.data = data;
        Ok(())
    }
}

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

#[account]
pub struct MyAccount {
    pub data: u64,
}

When to use Anchor:

• Building DeFi, NFT, or standard programs
• Need TypeScript client generation with IDL
• Want faster development with less boilerplate
• Following common Solana patterns
• New to Solana development

Installation:

cargo install --git https://github.com/coral-xyz/anchor avm --locked --force
avm install latest
avm use latest
anchor --version

Create project:

anchor init my_project
cd my_project
anchor build
anchor test

→ See references/anchor.md for complete Anchor guide

Advanced: Native Rust

Native Rust provides maximum control, optimization potential, and deeper understanding of Solana's runtime:

use solana_program::{
    account_info::AccountInfo,
    entrypoint,
    entrypoint::ProgramResult,
    pubkey::Pubkey,
    msg,
};

entrypoint!(process_instruction);

pub fn process_instruction(
    program_id: &Pubkey,
    accounts: &[AccountInfo],
    instruction_data: &[u8],
) -> ProgramResult {
    msg!("Processing instruction");
    // Manual account parsing and validation
    // Manual instruction routing
    Ok(())
}

When to use Native Rust:

• Need maximum compute efficiency (CU optimization critical)
• Require advanced features (versioned transactions, durable nonces, ALTs)
• Learning Solana fundamentals from first principles
• Building highly optimized or specialized programs
• Framework overhead is unacceptable

Setup:

cargo new my_program --lib
cd my_program
# Configure Cargo.toml (see native-rust.md)
cargo build-sbf

→ See references/native-rust.md for complete native Rust guide

Common Tasks Quick Reference

Create a new program:

• Anchor:

  anchor init my_project

  → anchor.md#getting-started
• Native:

  cargo new my_program --lib

  → native-rust.md#setup

Initialize a PDA account:

• Anchor: Use

  #[account(init, seeds = [...], bump)]

  → pda.md#anchor
• Native: Manual

  invoke_signed

  with System Program → pda.md#native

Transfer SPL tokens:

• Anchor: Use

  anchor_spl::token::transfer

  → tokens-operations.md#transferring-tokens
• Native: CPI to Token Program → tokens-operations.md#transferring-tokens

Test your program:

• Both: Mollusk for fast unit tests → testing-frameworks.md#mollusk-testing
• Anchor:

  anchor test

  for integration tests → testing-frameworks.md#anchor-specific-testing

Local development with mainnet forking:

• Both:

  surfpool start

  for mainnet-forked local network → surfpool.md

Test with mainnet state (Jupiter, Raydium CPIs):

• Both: Use Surfpool JIT forking → surfpool.md#mainnet-forking

Profile compute units in detail:

• Both:

  surfnet_profileTransaction

  cheatcode → surfpool.md#transaction-profiling

Deploy to devnet:

• Anchor:

  anchor deploy

  → deployment.md#anchor
• Native:

  solana program deploy

  → deployment.md#native

Deploy to production (verified builds):

• Both:

  solana-verify build

  +

  solana program deploy

  → production-deployment.md

Optimize compute units:

• Both: Profile with Mollusk bencher → compute-optimization.md

Handle 40+ accounts:

• Both: Use Address Lookup Tables → versioned-transactions.md

Offline transaction signing:

• Both: Use durable nonces → durable-nonces.md

Decision Guide

Note: You can also start with Anchor for rapid development, then optimize critical paths with native Rust patterns if needed.

Typical Development Workflow

Anchor Workflow

1. Init:

   anchor init my_project

2. Define accounts: Use

   #[derive(Accounts)]

   with constraints
3. Implement instructions: Write functions in

   #[program]

   module
4. Define state: Use

   #[account]

   macro for account structures
5. Test: Write tests in

   tests/

   , run

   anchor test

6. Deploy:

   anchor deploy

   to configured network
7. Client: Import generated IDL and types in TypeScript/Rust

Native Rust Workflow

1. Setup:

   cargo new my_program --lib

   , configure Cargo.toml
2. Define entrypoint: Implement

   process_instruction

   function
3. Define state: Manual Borsh serialization structs
4. Implement instructions: Manual routing and account parsing
5. Validate accounts: Explicit ownership, signer, writable checks
6. Test: Write Mollusk tests, run

   cargo test

7. Build:

   cargo build-sbf

8. Deploy:

   solana program deploy target/deploy/program.so

9. Client: Build client manually or use web3.js/rs

Best Practices

General (Both Approaches)

✅ Always validate accounts: Check ownership, signers, mutability ✅ Use checked arithmetic:

.checked_add()

.checked_sub()

Anchor-Specific

✅ Use

InitSpace

has_one

Program<'info, T>

emit!

Native Rust-Specific

✅ Use

next_account_info

create_program_address

solana-verify build

Security Considerations

Both frameworks require security vigilance:

⚠️ Common vulnerabilities:

• Missing signer checks
• Integer overflow/underflow
• Account confusion attacks
• PDA substitution
• Arbitrary CPI targets
• Missing account ownership checks
• Insufficient rent exemption
• Account closing without zeroing

→ For defensive programming patterns and secure coding practices, see security.md

That guide provides:

• Core security rules and principles
• Account validation patterns
• Arithmetic safety guidelines
• Pre-deployment security checklist

→ For comprehensive security audits, use the

solana-security

That skill provides:

• Systematic vulnerability analysis
• Attack scenarios and exploit POCs
• Framework-specific security reviews
• Professional audit workflows

When to Switch or Combine

Start with Anchor, optimize later:

• Build MVP with Anchor for speed
• Profile to find CU bottlenecks
• Optimize critical paths with native patterns
• Keep Anchor for non-critical code

Start with Native, add Anchor features:

• Build core program logic in native Rust
• Use Anchor's client generation separately
• Leverage anchor-spl for common patterns
• Maintain control where it matters

Use both in a workspace:

[workspace]
members = [
    "programs/core",      # Native Rust
    "programs/wrapper",   # Anchor facade
]
