Creating and Managing Wallets
Solana · Chapter 4
Creating and Managing Wallets
A wallet helps you manage keys and approve actions. Assets are recorded on the network; the wallet provides the keys used to authorize transactions.
The basics
- Your public address can be shared to receive test SOL. Your private key and recovery phrase must stay private.
- Use a separate development wallet rather than your everyday wallet.
- Check the network before requesting funds. An airdrop on Devnet does not fund Mainnet.
Try it yourself
In Playground, request Devnet SOL using the official faucet linked in the quick start. Check the balance and locate your public address in the Devnet explorer.
