#CryptoSecurity101

Centralized exchanges, self-custody wallets and DeFi dapps all share one weak link: the human who clicks “Confirm.” Fortify your habits before chasing returns. Start with app-based two-factor authentication; SMS codes can be SIM-swapped. Next, move long-term holdings to a hardware wallet, isolating keys from malware. Always verify URLs and contract addresses; phishing pages often look pixel-perfect. On-chain, use allowance revokers to cut old token approvals. Back up your seed phrase offline, split it if needed, and never store a photo in the cloud. Finally, whitelist withdrawal addresses so an attacker can’t drain funds even with your password. Security is boring—until it isn’t—so make it a daily routine.
