Basic Safety and Security Tips

What is a Secret Recovery Phrase in cryptowallets?

The use of a seed phrase, or Secret Recovery Phrase, is a standard most crypto wallets use. It's generated randomly when you create your cryptowallet, and provides access to all the accounts (addresses) within your wallet.

Don’t share your Secret Recovery Phrase and private keys

Anyone who has your Secret Recovery Phrase or private keys can control your assets, and therefore send tokens out of your accounts. Never share them with anyone, including the Undeads team or anyone claiming to represent us.
Undeads will never ask you to provide your Secret Recovery Phrase. If someone claims that we do, insist on not sharing.
This applies to websites and apps, as well.

If you have a large value of tokens in your account(s), consider getting a hardware wallet.
Hardware wallets are commonly thought to be the safest way to store your tokens. They are often referred to as 'cold' wallets, since they're disconnected from the internet most or all of the time. This approach means your private keys are never reachable by bad actors online, with the hardware wallet itself required to sign (authorize) any transactions.
There is no such thing as too much safety. The basic guide here is by no means comprehensive. Always learn how to better protect your tokens, by learning from the community, informative materials or discussion channels.

What are token approvals and why do you need them?

Token approvals grant permission for a dapp to access and move a specific type of token and token amount from your wallet. If you are not careful about what token approvals you are approving in your cyptowallet, then this could potentially be an attack vector for your wallet to get drained.
To avoid this from happening try and follow these guidelines:

• Always check what a dapp is actually requesting before clicking ‘approve’.
• DYOR. The best time to get in the habit of performing due diligence on any dapp before interacting with it was six months ago; the second best time is today. Look out for misspellings, low-quality images/logos, and other giveaways.
• Remember that . If you’re being offered overwhelming profits, you’re probably on thin ice.

Keep your passwords safe

Increase complexity of your passwords, change them from time to time and follow basic password safety tips:

• Make them long. At least 16 characters—longer is stronger!
• Make them random. Two ways to do this are: Use a random string of mixed-case letters, numbers and symbols.
• Make them unique. Use a different strong password for each account.
