SolScript vs Anchor: Solidity vs Rust for Solana
SolScript and Anchor are both tools for building Solana programs. SolScript uses Solidity syntax and compiles to Anchor/Rust code. Anchor is the native Rust framework. Here's how they compare.
Key Takeaways
- SolScript is best for Ethereum developers who want to build on Solana using familiar Solidity syntax.
- Anchor is best for Rust developers who want full control over their Solana programs.
- SolScript generates Anchor code, so the output is fully compatible and equally performant.
- SolScript handles PDA derivation, account validation, and boilerplate automatically.
Feature Comparison
| Feature | SolScript | Anchor |
|---|---|---|
| Language | Solidity | Rust |
| Learning curve (ETH devs) | Minimal | Steep |
| Learning curve (Rust devs) | Medium | Minimal |
| PDA handling | Automatic | Manual (macros) |
| Account validation | Automatic | Derive macros |
| Boilerplate | Low | Medium |
| Output | Rust/Anchor or BPF | BPF |
| Browser compiler | Yes (WASM) | No |
| Ecosystem maturity | Beta | Production |
| Auditable code | Yes (generated Rust) | Yes (native Rust) |
Code Comparison: Counter Contract
The same counter contract written in SolScript vs Anchor. Notice the difference in verbosity and boilerplate.
SolScript (Solidity syntax)
counter.sol
contract Counter {
uint256 public count;
address public owner;
event Incremented(address by, uint256 newValue);
error Unauthorized();
modifier onlyOwner() {
if (msg.sender != owner) revert Unauthorized();
_;
}
constructor() {
owner = msg.sender;
}
function increment() public {
count += 1;
emit Incremented(msg.sender, count);
}
function reset() public onlyOwner {
count = 0;
}
} Anchor (Rust)
counter.rs
use anchor_lang::prelude::*;
declare_id!("...");
#[program]
pub mod counter {
use super::*;
pub fn initialize(ctx: Context<Initialize>) -> Result<()> {
let counter = &mut ctx.accounts.counter;
counter.count = 0;
counter.owner = ctx.accounts.signer.key();
Ok(())
}
pub fn increment(ctx: Context<Increment>) -> Result<()> {
let counter = &mut ctx.accounts.counter;
counter.count += 1;
emit!(Incremented {
by: ctx.accounts.signer.key(),
new_value: counter.count,
});
Ok(())
}
pub fn reset(ctx: Context<Reset>) -> Result<()> {
let counter = &mut ctx.accounts.counter;
require!(counter.owner == ctx.accounts.signer.key(),
CounterError::Unauthorized);
counter.count = 0;
Ok(())
}
}
#[derive(Accounts)]
pub struct Initialize<'info> {
#[account(init, payer = signer, space = 8 + 8 + 32)]
pub counter: Account<'info, Counter>,
#[account(mut)]
pub signer: Signer<'info>,
pub system_program: Program<'info, System>,
}

- You're building complex DeFi protocols at scale
- You need access to the full Anchor ecosystem
Frequently Asked Questions
What is the difference between SolScript and Anchor? ▼
SolScript lets you write Solana contracts in Solidity syntax, then compiles them to Anchor/Rust code. Anchor requires writing Rust directly. SolScript is ideal for developers coming from Ethereum who want to build on Solana without learning Rust.
Is SolScript as performant as Anchor? ▼
Yes. SolScript generates standard Anchor/Rust code, so the compiled output has identical performance. The generated code is auditable and can be modified before deployment.
Can I use SolScript with existing Anchor projects? ▼
SolScript generates standalone Anchor programs. You can use the generated Rust code alongside existing Anchor projects, or integrate SolScript-compiled programs with Anchor frontends using standard Solana SDKs.
Do I need to know Rust to use SolScript? ▼
No. SolScript handles the Solidity-to-Rust compilation automatically. However, understanding the generated Anchor code is helpful for advanced debugging and optimization.
Which should I choose for a new Solana project? ▼
Choose SolScript if your team has Solidity experience and wants rapid development. Choose Anchor directly if your team knows Rust and wants full control over the program code.
