In recent years, blockchain technology has advanced significantly, and smart contracts are at the core of this revolution. Smart contracts are self-executing contracts where the terms are directly written into code. Solana, known for its high speed and low transaction costs, has become a popular blockchain for developers. In this guide, we’ll walk through the steps to get started as a smart contract developer using Solana.
**
Solana architecture:**
- Setting Up the Development Environment
To begin working with Solana, you’ll need to install the Solana CLI (Command Line Interface). This tool allows you to interact with the Solana blockchain from your terminal.
*Installing Solana on macOS & Linux:
*
Open your favourite terminal application and install the Solana release by running:
2. Creating a New Wallet
After installing the Solana CLI, the next step is to create a wallet, which will hold your Solana (SOL) tokens and allow you to interact with the blockchain.
Run the following command to create a new keypair:
solana-keygen new
➜ ~ solana address
Error: No default signer found, run "solana-keygen new -o /Users/saurabh/.config/solana/id.json" to create a new one
➜ ~ solana-keygen new
Generating a new keypair
solana address
47ywpno1NYn1tFQrSa6m9x4VoVSgvLiDYGuxCD2CKxEV
Generating a new keypair
For added security, enter a BIP39 passphrase
NOTE! This passphrase improves security of the recovery seed phrase NOT the
keypair file itself, which is stored as insecure plain text
BIP39 Passphrase (empty for none):
Wrote new keypair to /Users/saurabh/.config/solana/id.json
===================================================================
pubkey: 47ywpno1NYn1tFQrSa6m9x4VoVSgvLiDYGuxCD2CKxE
This command generates a public and private keypair, which is essential for signing transactions. For added security, you can set a BIP39 passphrase. This passphrase adds another layer of protection to your wallet's recovery seed phrase.
Once your wallet is created, you can check your public address by running:
solana address
Make a note of this address as it will be needed for testing and interacting with your smart contracts.
3. Setting Up a Development Environment
Since real SOL tokens cost money, it’s best to test your smart contracts on Solana’s Devnet, a test network where you can request free tokens.
To configure your CLI to connect to the Devnet, run:
solana config set --url https://api.devnet.solana.com
You can check if your Devnet setup is working by checking your public address again.
*4. Funding Your Wallet with Test SOL Tokens
*
On Devnet, you can request free SOL tokens to deploy and test your smart contracts. To airdrop 2 SOL to your wallet, use the following command:
After the airdrop, you can confirm your wallet balance and see if the tokens arrived successfully.
5. Checking Transactions on Solana Explorer
Once you've received SOL tokens in your wallet, you can view transaction details on Solana’s Devnet Explorer. For instance, visit Solana Explorer and enter your wallet's public address to track your balance and transaction history.
Using the explorer, you can verify all transactions and monitor how your smart contracts are performing on the network.
6. Running on Testnet and Local Blockchain
Once you’re comfortable with Devnet, you can also test on Solana’s Testnet, which is closer in performance to the Mainnet. Additionally, you can set up a local Solana blockchain for offline development and testing.
To configure your CLI for a local blockchain setup, use the RPC URL of your localhost and perform an airdrop as follows:
*> solana config set --url http://localhost:8899 solana airdrop 2
*
This step enables a safe environment for rigorous testing without any real tokens involved.
**
Final Thoughts**
Becoming a smart contract developer on Solana involves setting up your environment, creating a wallet, and testing contracts on Devnet and Testnet before moving to the Mainnet. With the Solana CLI and Devnet tokens, you’re ready to begin deploying smart contracts on one of the fastest-growing blockchain ecosystems.
Embrace these steps, and you’ll be well on your way to becoming a proficient smart contract developer on Solana!
