Wallet security


I have recently read that online wallets for cryptocurrency storage are generally not suggested as a safe deposit
method .
Is it enough :
a) to frequently check the url address (https form) ? b)to restore account using the seed phrase ?
How does the waves decentralised exchange platform (DEX) contribute to asset protection?


Firstly, on Waves DEX only you have access to your account and your assets - unlike centralised exchanges, where you give up control of your tokens.

Cryptocurrencies are still primarily traded on centralised exchanges, and user
funds are at risk of hacking and theft. Waves’ decentralised exchange (DEX) ensures users maintain control of their funds, since trades are settled on the blockchain.

Secondly, you can now use Ledger Nano S to better protect your account. https://docs.wavesplatform.com/en/waves-client/account-management/ledger-nano.html

Thirdly, we are currently working on 2FA for blockchain accounts.
