To protect your DeFi wallets, you must use several protection methods to secure your seed phrase.

Keeping your seed phrase online is a significant security risk that should be avoided. When stored online—whether in cloud storage, email, or even as a digital file on your computer—your seed phrase becomes vulnerable to hacking, phishing attacks, and malware.

Writing your seed phrase down on paper is one of the most secure methods to protect it. Unlike digital storage, a physical copy of your seed phrase is not susceptible to hacking or malware.

When writing it down, ensure that you double-check your seed Phrase and each word is legible and in the correct order, as any mistakes could make it impossible to recover your wallet.

After writing down your seed phrase, place it securely in a fireproof, waterproof safe place or a safety deposit box. Consider making multiple copies and storing them in separate, secure places to safeguard against potential disasters like fire and flooding.

If you have already set up your wallet and haven’t written down the seed phrase, you may not be able to view it again within most wallets for security reasons. If available, some wallets have a backup option where you can view or re-confirm your seed phrase, but this typically requires entering your wallet password or passcode. 

Some wallets also ask you to write down some words from the seed Phrase to confirm that you saved it correctly, other wallets have an option to write it down later. You can find it in your wallet's security settings.
