If this is your first time using the Solana CLI, you will need to generate a new key pair. This key pair will serve as your identity when interacting with the SOON Testnet. To generate a new keypair, run the following command: 
solana-keygen new
You should see output similar to: 
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 /home/xxxxx
============================================================================
pubkey: AEG18Z4ESnzEh1rcgUHk1dLwVY4LyfZ6TWzgShGry5UN
============================================================================
Save this seed phrase and your BIP39 passphrase to recover your new keypair:

Important Security Considerations

  • Private Key Security: The private key in your keypair should never be shared or exposed. It grants access to your account and the ability to sign transactions on your behalf. Always keep this file secure.
  • Public Key: The public key, derived from the keypair, will serve as your wallet address and can be shared with others to receive funds or interact with contracts.
