Solana CLI Basics
Solana Config
To see your current config:
$solana config get
You should see output like the following:
Config File: /Users/test/.config/solana/cli/config.ymlRPC URL: https://api.mainnet-beta.solana.comWebSocket URL: wss://api.mainnet-beta.solana.com/ (computed)Keypair Path: /Users/test/.config/solana/id.jsonCommitment: confirmed
The RPC URL and Websocket URL specify the Solana cluster the CLI makes requests to.
You can update the Solana CLI cluster using the following commands:
$solana config set --url mainnet-beta$solana config set --url devnet$solana config set --url localhost$solana config set --url testnet
You can also use the following short options:
$solana config set -um # For mainnet-beta$solana config set -ud # For devnet$solana config set -ul # For localhost$solana config set -ut # For testnet
The Keypair Path points to the default Solana wallet (keypair) used by the
Solana CLI to pay transaction fees and deploy programs. By default, this file is
stored at ~/.config/solana/id.json.
Create Wallet
To send transactions using the Solana CLI, you need a Solana wallet funded with SOL.
To generate a keypair at the default Keypair Path, run the following command:
$solana-keygen new
You should see output like the following:
Generating a new keypairFor added security, enter a BIP39 passphraseNOTE! This passphrase improves security of the recovery seed phrase NOT thekeypair file itself, which is stored as insecure plain textBIP39 Passphrase (empty for none):Wrote new keypair to /Users/test/.config/solana/id.json===========================================================================pubkey: 8dBTPrjnkXyuQK3KDt9wrZBfizEZijmmUQXVHpFbVwGT===========================================================================Save this seed phrase and your BIP39 passphrase to recover your new keypair:cream bleak tortoise ocean nasty game gift forget fancy salon mimic amazing===========================================================================
If you already have a file system wallet saved at the default location, this
command doesn't override it unless you explicitly force override using the
--force flag.
To view your wallet's address (public key), run:
$solana address
Airdrop SOL
Request an airdrop of SOL to your wallet to pay for transactions and program deployments.
Set your cluster to the devnet:
$solana config set -ud
Then request an airdrop of devnet SOL:
$solana airdrop 2
Devnet airdrops limit requests to 5 SOL per request. If you hit rate limits or encounter errors, try using the Web Faucet instead.
To check your wallet's SOL balance, run the following command:
$solana balance
Run Local Validator
The Solana CLI includes a built-in test validator for local development.
In a separate terminal, run the following command to start a local validator:
$solana-test-validator
Remember to also update your CLI to use localhost before running Solana CLI commands:
$solana config set -ul
