Deploying Solana Tokens from Scratch: A Step-by-Step Guide
As a developer building on the Solana blockchain, you’ve probably come across the popularity of Solana-based tokens. One such token is SPL (Solana Plasma), which is used for a variety of applications, such as decentralized finance (DeFi) platforms and decentralized governance systems. In this article, we’ll walk you through the process of deploying an SPL token from scratch using the Solana SDK.
Prerequisites
Before you begin, make sure you have the following:
- Solana CLI installed on your machine
- A Solana node running the mainnet testnet (we recommend using the “solana-cli” tool to interact with the node)
- A basic understanding of Solidity and Solana-specific concepts
1. Step 1: Clone the SPL Token Repository
Create a new repository for the 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 with 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.
3. Step 1: Configure Solana Node
Update the Solana node configuration to use the “solana-cli” tool to interact with the 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 the Wallet JSON file.
4. Step 5: Initialize and compile your token
Create a new folder for your token and initialize it with the following commands:
mkdir -p tokens/spl-token
cd tokens/spl-token
npm install solana cli --save-dev
npx solana-cli init spl-token
This will create a new spl-token' directory with basic configuration.
Step 5: Create and install the token
Create a new file calledspl-token.sol’ in the tokens/spl-token' directory. This is the Solidity smart contract for the SPL token.
// tokens/spl-token/spl-token.sol
pragma solidity ^0.8.0;
contract SplToken {
map state balances(address => uint256);
function deposit(address _owner, uint256 amount) public onlyOwner {
balances[_owner] += amount;
}
function withdraw(address _owner, uint256 amount) public onlyOwner {
request(balances[_owner] >= amount, "Insufficient balance");
balances[_owner] -= amount;
}
}
function onlyOwner() internal view requestOwnership {
request(msg.sender == address(_owner), "Only the owner can call this function");
}
This contract provides basic functionality for depositing and withdrawing SPL tokens.
6. Step 2: Compile and install your token
Compile the "spl-token.sol" file with the following command:
solc --bin spl-token.sol --allow-abi -r solana
This will create a new spl-token.json` file containing the compiled contract bytecode.
Deploy the token to the Solana mainnet testnet using the following commands:
npx solana-cli deploy --pubkey \
--chainid \
--contractname spl-token \
--storage-account \
--accounts account1,account2,account3 \
--gas 2000000 \
--gas-price 10 ether
Replace the key “” with the actual public key of your mainnet wallet.
