Deploying a Solana Token from Scratch: A Step-by-Step Guide

As a developer building on the Solana blockchain, you are likely to come across the popularity of Solana-based tokens. One such token is SPL (Solana Plasma), which is used for various applications such as decentralized finance (DeFi) platforms and decentralized governance systems. In this article, we’ll walk through the process of deploying an SPL token from scratch using the Solana SDK.

Prerequisites

Before you begin, make sure you have the following:

• Make sure the Solana CLI is installed on your machine

• A Solana Node running the mainnet testnet (we recommend using the solana-cli tool to interact with your node)

• A basic understanding of Solidity and Solana-specific concepts

Step 1: Clone the SPL Token Repository

Create a new repository for your SPL token by cloning the official SPL token repository:

git clone 

This will create a new directory structure with the necessary files and folders.

Step 2: Set Up Your Development Environment

Create a new Solana wallet using the solana-keygen command. This will generate a JSON key pair for your wallet.

solana-keygen --key-size=4096 --out keypair.json wallet

This will create a wallet.json file containing your private and public keys.

Step 3: Set Up Your Solana Node

Update the Solana node’s configuration to use the solana-cli tool to interact with your local blockchain. Create a new config.toml file in the ~/.solana/cli/config.toml directory:

[cli]

keypair = "path/to/wallet.key"

Replace "path/to/wallet.key" with the actual path to your wallet JSON file.

Step 4: Initialize and Compile Your Token

Create a new folder for your token and initialize it using the following commands:

mkdir -p tokens/spl-token

cd tokens/spl-token


npm install solanacli --save-dev

npx solana-cli init spl-token

This will create a new spl-token directory with a basic configuration.

Step 5: Create and Deploy Your Token

Create a new file named spl-token.sol in the tokens/spl-token directory. This is the Solidity smart contract for your SPL token.

// tokens/spl-token/spl-token.sol


pragma solidity ^0.8.0;


contract SplToken { {

  mapping ( address => uint256 ) public balances ;


  function deposit ( address _owner , uint256 amount ) public onlyOwner { ;

    balances[_owner] += amount;

  } }


  function withdraw ( address _owner , uint256 amount ) public onlyOwner { ;

    require( balances[_owner] >= amount, "Insufficient balance");

    balances [_owner] -= amount;

  } }

} }


function onlyOwner() internal view requiresOwnership {) .

  require ( msg . sender == address ( _owner ) ) ;

} }

This contract provides basic functionality for depositing and withdrawing SPL tokens.

Step 6: Compile and Deploy Your Token

Compile your spl-token.sol file using the following command:

solc -- bin spl - token . sol -- allow -- or solana

This will create a new spl-token.json file containing the compiled contract’s bytecode.

Deploy your token to the Solana mainnet testnet using the following commands:

npx solana-cli deploy --pubkey < YOUR_MAINNET_PUBLIC_KEY > \

  --chain-id\

  --contract-name spl-token \

  --storage-account \

  --accounts account1,account2,account3\

  --gas 2000000\

  --gas-price 10 ether

Replace with the actual public key of your mainnet wallet.
