Your seed phrase is the only key that matters. Whoever has it controls your wallet — no exceptions, no recovery, no appeals. Write it down on paper, store it somewhere private, and never enter it into any website, app, or chat. Not even once.
Hardware wallets are not optional for serious holdings. If your private key never touches an internet-connected device, an entire class of attacks disappears. Treat it like a vault — not something you casually carry or expose.

Every smart contract interaction carries risk. Before approving a transaction, understand exactly what you’re signing. Blind approvals are the root of most wallet drains. If a dApp requests unlimited token access, revoke it immediately after use.
Phishing in Web3 doesn’t look obvious. It looks like a support DM, a sponsored link above the real site, a nearly identical domain, or a random airdrop. The danger is subtle — slow down before every click.
Use separate wallets for different purposes. One for storage (cold, untouched), another for interaction (minting, claiming, experimenting). This separation alone can save your entire portfolio.

Token approvals don’t expire — they stack quietly over time. Regularly audit and revoke anything you no longer need. Old permissions are a hidden vulnerability.
For large holdings, multi-signature wallets are worth the extra effort. If one device gets compromised, your funds remain protected. A few extra steps now can prevent total loss later.

No protocol is risk-free. Not the biggest names, not the most trusted platforms. Spread your exposure, review it often, and never keep more on-chain than you can afford to lose.
Security in Web3 isn’t a setup — it’s a mindset.
