Your seed phrase is the only key that truly exists. Not your password. Not your email. Not your 2FA code. The seed phrase. Write it down by hand, store it somewhere physical, and never — not once — let it touch a screen you didn't own from day one.

Most people think they'll remember to be careful "when it matters." The problem is, by the time it matters, you've already clicked the link.

Four things that block over 90% of attacks in Web3:

Never open wallet-related links sent through DMs, even from people you know. Their account might already be compromised.

Never enter your seed phrase anywhere, ever. No legitimate app, platform, or support team will ask for it. If they do, that is the attack.

Never sign a transaction you don't fully understand. Tools like Rabby Wallet show you what you're actually approving before you approve it. Use them.

Never connect your main wallet to unknown dApps. Keep a second wallet with only what you're willing to lose for testing new protocols.

Hardware wallet for the bulk of your stack. Hot wallet only for what you're actively using. That split alone changes your risk profile entirely.

And the one thing people skip most: smart contract audits. Before depositing into any DeFi protocol, check whether the contract has been audited, and by whom. "High APY, no audit" is not an opportunity. It's a trap with good marketing.

The future of Web3 genuinely belongs to people who stay cautious. Not paranoid — cautious. There's a difference. Paranoid people don't participate. Cautious people participate and keep their assets.
