Additional protection against hacking and theft of funds from your wallet can be the use of so-called “cold” wallets, which are not connected to the network and are offline until you need them. They are ideal for storing your tokens. You can always plug in the wallet and make the transactions you need, and the rest of the time your tokens will be safe.
For example: Tangem, Ledger, Trezor.
Buy cold wallets only from official manufacturer sites.
Marketplaces, chain stores (even big ones), ad sites, and even more so used devices can be dangerous for your funds!
