Blockchain is designed to be trustless. Ironically, in crypto, you must assume that everyone is trying to lie and steal from you.
Even if you are not doing anything out of the ordinary, even your priceless meme coins could still be drained, like in the recent ~500m ledger attack.
Here are a couple of quick tips on how to reduce such risks.
Separate your accounts
Most of your funds must be stored on a separate, dedicated address in a hardware wallet that is not used for your daily activities. Your hardware wallet can derive multiple accounts from a single seed phrase and splitting your daily account from your savings account this way will limit the impact of a compromise.
If you want to go further, set up an additional account derived from 13th or 25th word pass phrase, hidden behind a separate pin code.
Assume malicious destination
Always add the recipient addresses to your address book first and never copy or type these addresses again.
Attackers will try to fool you by generating malicious addresses matching most of the letters in the expected address so you must compare every single letter when adding new addresses to your address book.
You will see malicious addresses in the list of your past transactions, in your emails, messengers and your social media – don't trust anything not in your address book.
Always check the display of your hardware wallet when signing transactions – read and compare the destination address diligently.
Stay safe out there!
