While crypto wallets are constantly improving, there is still more to be done. The post describes a potential wallet enhancement, which will provide users access to necessary information about the Dapp they’re using, helping them more easily weed out scam attempts.
Phishing scams targeting #crypto wallets are everywhere. In our latest blog post, @viktorot details one such attack and offers suggestions on how wallets can improve their security.
