Configure your wallet

This step will help you set up your wallet as the first step to using Kroma.

A seed phrase generated by a blockchain wallet is important information that can be used to recover or reset the wallet. Therefore, it is crucial to store the seed phrase safely. Here are some tips for securely storing seed phrases:

  1. Store the seed phrase offline. Storing the seed phrase on a computer or smartphone connected to the internet poses a risk of exposure to hacking or malware. Instead, write the seed phrase on an offline storage medium, such as paper or metal.

  2. Store the seed phrase in a secure location. Keep the paper or metal storage medium with the seed phrase in a safe and confidential place. For example, a safe that can protect it from fire or flood would be ideal.

  3. Encrypt the seed phrase. Use encryption when storing the seed phrase for added security. For example, store the seed phrase in an encrypted file or add a password required for decryption to limit access to the seed phrase.

  4. Do not disclose the seed phrase. Do not share the seed phrase with anyone else. Do not show the seed phrase to anyone or share it via phone, email, or any other means.

  5. Back up the seed phrase frequently. The seed phrase can be lost at any time. Therefore, frequently back up the seed phrase to a secure location and delete previous versions from the safe location when updating.

By following these tips, you can securely store the seed phrase and protect yourself from the risks of losing your wallet or exposure to hackers.
