Solana Quick Start Guide
Welcome to the Solana Quick Start Guide! This hands-on guide will introduce you to the core concepts for building on Solana, regardless of your prior experience. By the end of this tutorial, you'll have a basic foundation in Solana development and be ready to explore more advanced topics.
What You'll Learn #
In this tutorial, you'll learn about:
- Understanding Accounts: Explore how data is stored on the Solana network.
- Sending Transactions: Learn to interact with the Solana network by sending transactions.
- Building and Deploying Programs: Create your first Solana program and deploy it to the network.
- Program Derived Addresses (PDAs): Learn how to use PDAs to create deterministic addresses for accounts.
- Cross-Program Invocations (CPIs): Learn how to make your programs interact with other programs on Solana.
The best part? You don't need to install anything! We'll be using Solana Playground, a browser-based development environment, for all our examples. This means you can follow along, copy and paste code, and see results immediately, all from your web browser. Basic programming knowledge is helpful but not required.
Let's dive in and start building on Solana!
Игровая площадка Солана #
Solana Playground (Solpg) is a browser-based development environment that allows you to quickly develop, deploy, and test Solana programs!
Open a new tab in your web browser and navigate to https://beta.solpg.io/.
Create Playground Wallet #
If you're new to Solana Playground, the first step is to create your Playground Wallet. This wallet will allow you to interact with the Solana network right from your browser.
Step 1. Connect to Playground #
Click the "Not connected" button at the bottom left of the screen.
Not Connected
Step 2. Create Your Wallet #
You'll see an option to save your wallet's keypair. Optionally, save your wallet's keypair for backup and then click "Continue".
Create Playground Wallet
You should now see your wallet's address, SOL balance, and connected cluster (devnet by default) at the bottom of the window.
Connected
Your Playground Wallet will be saved in your browser's local storage. Clearing your browser cache will remove your saved wallet.
Some definitions you may find helpful:
- wallet address: a unique identifier for a digital wallet, used to send or receive crypto assets on a blockchain. Each wallet address is a string of alphanumeric characters that represents a specific destination on the network. Think of it like an email address or bank account number—if someone wants to send you cryptocurrency, they need your wallet address to direct the funds.
- connected cluster: a set of network nodes that work together to maintain a synchronized copy of the blockchain. These clusters are essential for providing a decentralized, distributed ledger and powering the Solana network by validating transactions, securing the chain, and executing programs (smart contracts).
Get Devnet SOL #
Before we start building, we first need some devnet SOL.
From a developer's perspective, SOL is required for two main use cases:
- To create accounts where we can store data or deploy programs
- To pay for transaction fees when we interact with the network
Below are two methods to fund your wallet with devnet SOL:
Option 1: Using the Playground Terminal #
To fund your Playground wallet with devnet SOL. In the Playground terminal, run:
solana airdrop 5Option 2: Using the Devnet Faucet #
If the airdrop command doesn't work (due to rate limits or errors), you can use the Web Faucet.
- Enter your wallet address (found at the bottom of the Playground screen) and select an amount
- Click "Confirm Airdrop" to receive your devnet SOL
