Wallet security is operational, not theoretical. Most losses come from phishing, seed phrase theft, malicious approvals, and compromised devices — not from broken cryptography.
Good habits compound: separate wallets for experiments and savings, verify URLs before connecting, and never enter a seed phrase into any website or app that asks for it online.
Assume every unsolicited message about your wallet is hostile. Real protocols do not need your seed phrase, and legitimate support will never ask you to sign a mystery transaction to fix an account.
