--- title: Paper Wallet Usage --- Solana commands can be run without ever saving a keypair to disk on a machine. If avoiding writing a private key to disk is a security concern of yours, you've come to the right place. > Even using this secure input method, it's still possible that a private key gets written to disk by unencrypted memory swaps. It is the user's responsibility to protect against this scenario. ## Before You Begin - [Install the Solana command-line tools](../cli/install-solana-cli-tools.md) ### Check your installation Check that `solana-keygen` is installed correctly by running: ```bash solana-keygen --version ``` ## Creating a Paper Wallet Using the `solana-keygen` tool, it is possible to generate new seed phrases as well as derive a keypair from an existing seed phrase and (optional) passphrase. The seed phrase and passphrase can be used together as a paper wallet. As long as you keep your seed phrase and passphrase stored safely, you can use them to access your account. > For more information about how seed phrases work, review this [Bitcoin Wiki page](https://en.bitcoin.it/wiki/Seed_phrase). ### Seed Phrase Generation Generating a new keypair can be done using the `solana-keygen new` command. The command will generate a random seed phrase, ask you to enter an optional passphrase, and then will display the derived public key and the generated seed phrase for your paper wallet. After copying down your seed phrase, you can use the [public key derivation](#public-key-derivation) instructions to verify that you have not made any errors. ```bash solana-keygen new --no-outfile ``` > If the `--no-outfile` flag is **omitted**, the default behavior is to write the keypair to `~/.config/solana/id.json`, resulting in a [file system wallet](../file-system-wallet/README.md) The output of this command will display a line like this: ```bash pubkey: 9ZNTfG4NyQgxy2SWjSiQoUyBPEvXT2xo7fKc5hPYYJ7b ``` The value shown after `pubkey:` is your _wallet address_. **Note:** In working with paper wallets and file system wallets, the terms "pubkey" and "wallet address" are sometimes used interchangably. > For added security, increase the seed phrase word count using the `--word-count` argument For full usage details run: ```bash solana-keygen new --help ``` ### Public Key Derivation Public keys can be derived from a seed phrase and a passphrase if you choose to use one. This is useful for using an offline-generated seed phrase to derive a valid public key. The `solana-keygen pubkey` command will walk you through entering your seed phrase and a passphrase if you chose to use one. ```bash solana-keygen pubkey ASK ``` > Note that you could potentially use different passphrases for the same seed phrase. Each unique passphrase will yield a different keypair. The `solana-keygen` tool uses the same BIP39 standard English word list as it does to generate seed phrases. If your seed phrase was generated with another tool that uses a different word list, you can still use `solana-keygen`, but will need to pass the `--skip-seed-phrase-validation` argument and forego this validation. ```bash solana-keygen pubkey ASK --skip-seed-phrase-validation ``` After entering your seed phrase with `solana-keygen pubkey ASK` the console will display a string of base-58 character. This is the _wallet address_ associated with your seed phrase. > Copy the derived address to a USB stick for easy usage on networked computers > A common next step is to [check the balance](#checking-account-balance) of the account associated with a public key For full usage details run: ```bash solana-keygen pubkey --help ``` ## Verifying the Keypair To verify you control the private key of a paper wallet address, use `solana-keygen verify`: ```bash solana-keygen verify ASK ``` where `` is replaced with the wallet address and they keyword `ASK` tells the command to prompt you for the keypair's seed phrase. Note that for security reasons, your seed phrase will not be displayed as you type. After entering your seed phrase, the command will output "Success" if the given public key matches the keypair generated from your seed phrase, and "Failed" otherwise. ## Checking Account Balance All that is needed to check an account balance is the public key of an account. To retrieve public keys securely from a paper wallet, follow the [Public Key Derivation](#public-key-derivation) instructions on an [air gapped computer](). Public keys can then be typed manually or transferred via a USB stick to a networked machine. Next, configure the `solana` CLI tool to [connect to a particular cluster](../cli/choose-a-cluster.md): ```bash solana config set --url # (i.e. https://api.mainnet-beta.solana.com) ``` Finally, to check the balance, run the following command: ```bash solana balance ``` ## Creating Multiple Paper Wallet Addresses You can create as many wallet addresses as you like. Simply re-run the steps in [Seed Phrase Generation](#seed-phrase-generation) or [Public Key Derivation](#public-key-derivation) to create a new address. Multiple wallet addresses can be useful if you want to transfer tokens between your own accounts for different purposes. ## Support Check out our [Wallet Support Page](../wallet-guide/support.md) for ways to get help.
