Deploying Zig Programs on Solana: A Step-by-Step Guide

Solana: zig programs on solana

When it comes to deploying programs on the Solana blockchain, users often face issues related to ELF (Executable and Linkable Format) files. In this article, we will explore how to deploy Zig programs on Solana using the popular Rust-based development environment.

What is Solana?

Solana is a fast, decentralized, and scalable blockchain platform that enables developers to build a wide range of applications, from decentralized finance (DeFi) protocols to gaming and social networking platforms. To deploy a program on Solana, you need to compile it using the Solana compiler (solc), which can be done in two main ways: via the command line or via the Solana development environment.

Why Zig?

Zig is a new programming language released by Zircon.io, an open source company based in California. It is designed to be fast and efficient, making it an excellent choice for building programs on the Solana blockchain. In this article, we will focus on deploying Zig programs on Solana using solc.

Why ELF?

The main reason you need an ELF file is that Solana uses a binary format called WASM (WebAssembly) to compile your program. However, when compiling with solc, you can choose to output the compiled code in a more traditional ELF format instead of WebAssembly. This allows you to deploy your Zig program on Solana using the solana-cli tool.

Step 1: Install solc and cargo

To get started, you will need to install solc and Cargo, Rust’s package manager. You can do this by running the following commands:


Install solc using pip

sudo apt-get update && sudo apt-get install -y libzircon-dev libwasm-time-0-dev


Install Cargo

sudo add-apt-repository -y "deadsnakes-org/deb-pull"

sudo apt-get update

sudo apt-get install -y cargo

Step 2: Compile your . Zig program using groove

To compile the Zig program, use the following command:

cargo build --release --target solana-base32

Replace with the actual path to your . Zig file. The --release flag tells Cargo to compile your program in release mode, which should be sufficient for deployment to Solana.

Step 3: Deploy Your Program to Solana

To deploy your program to Solana, use the following command:

solana-cli deploy --pubkey

Replace with the actual path to your Zig file and with your Solana public key. This will upload your compiled program to the Solana network, allowing you to deploy it to your applications.

Example Use Case

Here is an example of how you can create a simple calculator application in Zig using solc:

const std = @import("std");

pub fn main() !void {

// Define a struct to represent our computer

const Calculator = struct {

pub add: fn(int, int) int,

pub decrement: fn(int, int) int,

};

// Initialize the calculator with some initial values

var calculator: Calculator = .{

.add = std.mem.add,

.subtract = std.mem.subtract,

};

// Create a new program using solc

const Program = try std.heap.page_allocator.alloc(Program, 2);

defer Program.deinit();

Program.* = try Program.init(allocator(), calculator);

// Test the add function

try calculator.add(10, 5);

}

This code defines a simple calculator application with „add” and „subtract” functions. Then compile this program into an ELF file using solc and deploy it to Solana using the solana-cli tool.

Conclusion

In this article, we explored how to deploy Zig programs to Solana using solc. By following these steps, you can compile your Zig programs using solc and deploy them to the Solana network.
